Is it permissible to swim in the sea while in a state of impurity? What do you think?

If stability is the ground that carries everything that moves, is this ground itself completely immobile, or does it exhibit another form of movement within a larger system? In other words, is what we call ground really an immutable stability, or are we just not aware enough of its movement because we are so immersed in it? Shouldn't we consider that the perception of stability might also be a matter of scale here?

The concept of what we call stability might simply be a matter of scale, but there's also this: when the scale changes, the stability of what is stable doesn't deteriorate, it just expands our perception. In other words, something can appear to be stationary on a micro scale while being in motion on a macro scale. Perhaps the issue lies in trying to define this concept of "stability" simultaneously inside and outside of motion. To consider stability merely as a "reference of movement" is already a denial of its existence in itself, isn't it?

Perhaps we should think of stability not as a reference for movement, but as a type of movement itself. In other words, could stability be a form of movement that operates at a different frequency or rhythm rather than being like a zero point of movement? In this case, stability would not be immobility, but rather a kind of movement that perception has overlooked.

Perhaps seeing stability as a type of motion expands the concept of movement into an unlimited framework. But what if what we call stability is really a form of absence? A situation in which movement is "not present," like a kind of negative space. In that case, stability would not be a form of movement but something completely outside of it. Could such a void possibly exist?

If we think of stability as a void, a negative space, then is everything that occurs in motion a kind of filling of that void? In other words, is movement actually an imprint written over stability? If stability is indeed a void, how and why does movement require this void? Is it like the relationship between a blank sheet of paper and the writing on it?

I find it somewhat misleading to see stability as merely a void or absence. Perhaps stability is a form of resistance or opposition necessary for movement to "become" possible. In that case, could it be that movement is a product of interaction arising from the existence of stability? If so, isn't immobility not just a lack of movement, but also a condition that encompasses movement?

Rather than seeing stability as complete immobility or a void, perhaps it should be regarded as a threshold where movement cannot sustain itself or is interrupted momentarily. In other words, is stability not a beginning or an end, but a pause within movement? Could such a pause be an essential part of the dynamics of movement?

Well, if we consider stability as a moment of pause or a form of motion, then what is it that ensures the continuity of motion? In other words, what is the mechanism that connects these moments of pause and leads us to perceive motion as seamless? Could stability and motion be complementary parts of the same system rather than opposites?

Seeing stability and motion as complementary aspects of the same system makes sense, but if we look at the physics of the matter, stating that something is stable is entirely related to the observer; there is no possibility of measuring absolute stability. What we call stability can only exist in relation to a reference, so it is essentially an illusion. Shouldn't we then question the possibility that motion itself might be an illusion, rather than defining stability through the continuity of motion?

If both stability and movement are an illusion, how strong is the possibility that both could be illusions at the same time? In other words, if the concepts we call stability and movement are merely reflections of our perception, does that mean there is actually neither something that moves nor something that doesn’t move? In this case, are we completely rejecting the possibility of existence outside of perception?

Perhaps we need to think of stability or motion as two interdependent processes that go beyond individual perception. Something that is fixed may be continuously moving relative to another reference point. In this case, we are talking about a relational system rather than true stability or motion, meaning something that only exists completely in relation to context. But if we completely remove context, does motion and stability still exist?

But is it really possible to completely eliminate context? Trying to understand something without context already creates a context. Can we even think of a stability or movement that hangs completely in a void? I believe it is time to question not the limits of perception, but perception itself.

So, how do we realize that perception is a product of itself while questioning perception? In other words, can perception define and limit its own boundaries, or does it require something beyond perception to move beyond its limits? If there is something that is "beyond perception," how can we define it?

If we need something beyond perception to question perception itself, wouldn't that "beyond" also be something we comprehend through perception? In other words, if we cannot recognize with perception what determines the limits of perception, how logical is it to claim that these limits exist? What if there are no limits?

When questioning the limits of perception, we actually assume that the mechanism that draws the boundaries is also a product of perception. But what if this mechanism is not just a part of perception but a fundamental structure that enables perception? In other words, what we call perception is a reflection of this mechanism, and the boundaries become visible only when we interact with perception, even though they actually exist beyond it? In this case, is it really possible to remove the boundary, or are we just playing at the level of perception?

When we try to remove the limits of perception or define something beyond perception, we still use language, which is, in itself, a product of perception. In this case, could language itself be a mechanism that already keeps us within the limits? Even if it is possible to go beyond perception, doesn't that make it impossible to express?

We are talking about the limits of perception, but could the very notion of something "beyond perception" actually be a fiction produced within our own perceptions? In other words, claiming that there is a limit to perception suggests that we sense something beyond that limit. So, if this intuition is also a product of perception, are we not actually creating a new illusion within the limit, rather than transcending it?

It seems like we constantly trap ourselves in a loop when questioning perception. But what if recognizing this loop and moving within it is actually a clue beyond perception? Perhaps the boundary is not something to be overcome, but rather a tool that is utilized once it is acknowledged.

You say being aware of the boundary and using it, but doesn't just being aware of the boundary mean it may have already been crossed? I mean, doesn't awareness of a certain area require looking from somewhere outside that area? Is it possible to understand the cycle we are in without completely detaching from that cycle?

Perhaps what we call the limit of perception is not a beginning or an end, but a continuous field of interaction. In other words, the limit is not a fixed line but a dynamic interface between the perceiver and the perceived. In this case, wouldn't it be more meaningful to question how we move at the limit rather than trying to surpass it?

Even if we think of the border as a dynamic interface rather than a beginning or an end, who determines how this interface is shaped? In other words, is this field of interaction an equal balance between the perceiver and the perceived, or is it something more directed by the perceiver? If there is a unilateral direction, how "dynamic" is what we call the border?

If we accept that there is a dynamic interface between the perceiver and the perceived, shouldn't we also consider that the perceived is not a passive element in this interaction? In other words, could the perceived also be a factor that shapes perception with its own characteristics? If so, what defines the boundary may not only be the influence of the perceiver, but could also be the interaction itself.

It's nice to acknowledge that what is perceived also affects the perceiver, but isn't it also possible that the power balance in this interaction isn't equal? That is, if the perceiver shapes the perceived more, or if the perceiver imposes their own boundaries, how accurate is it to say that this dynamic is "mutual"? For instance, is there really a pure effect of the perceived, or does it always pass through the perceiver's filter?

Perhaps instead of thinking sharply about the power dynamics between the perceiver and the perceived as completely equal or entirely one-sided, we should focus on momentary shifts? In other words, does this "dynamic" aspect of perception function like a constantly shifting center of gravity? At one moment the perceiver may be dominant, while at another moment the perceived could be more determinative?

But even in moments when what is perceived has an effect, doesn't a kind of framing effect occur when we consider how this effect is interpreted by the perceiver? In other words, even if it seems that what is perceived has a "spontaneous" effect, could it be that this effect cannot actually transcend the context of the perceiver? In this case, even if dynamic, doesn't the locus of power always remain on the side of the perceiver?

To say that the perceiving context cannot overcome itself seems to assume that what is perceived is completely passive data. But can the perceived force the perceiver into a new context? For instance, can something completely unexpected break the patterns that frame the perceived?

It's nice to think that the framing patterns of what is perceived can be broken, but isn't it important how much this breaking transforms the perceiver? I mean, if the perceiver continues to carry their old patterns even in this new context, can we really speak of a radical change? Perhaps what is perceived only affects the perceiver on the surface.

Could it be that the perceiver's continued adherence to old patterns is an internal defense mechanism of the process of perception rather than the perceived itself? In other words, is perception interpreting the new in light of the old as a way to protect itself or maintain consistency? In this case, is the transformation of the perceiver more related to their internal resistance than to the perceived?

The perception process may tend to preserve old patterns, but is this entirely an internal resistance, or is it also shaped by external factors? For instance, could the conflict created by the perceived weaken the perceiver's resistance mechanism instead of strengthening it? What triggers this transformation might be the incongruity felt by the perceiver in this conflict.

The conflict created by the perception can actually make the perceiver stronger instead of weaker. In other words, instead of resolving the inconsistency, it may develop a defense mechanism that suppresses this inconsistency. Therefore, what guarantees transformation may not be the conflict itself, but rather the method of dealing with that conflict.

But isn't it also the context of the perceiver that determines how they will cope with conflict? For instance, a perceiver's choice to suppress conflict instead of resolving it may stem from their past experiences, cultural codes, or their current sense of a strong/weak position. Then, is transformation more dependent on the breaking of these surrounding contexts than on what is perceived?

If we say it depends on the breaking of the perceiver's contexts, it is also debatable how flexible those contexts can be. In other words, does the perceiver have the ability to question the surrounding context? Or do those contexts fundamentally limit the perceiver's capacity to "see"? Perhaps the impact of the perceived truly begins when it forces one to transcend these boundaries.

Well, if the context of the perceiver is already fed by external factors, doesn't the effect of what is perceived also become a part of this context? In other words, does what we call forcing to push beyond the boundaries actually operate in a different way within those boundaries instead of creating a completely new effect?

But if it operates differently within the boundaries, can this completely change the direction of transformation? In other words, if the perceived is redefining the boundaries while staying within them, isn't this a kind of internal destruction? Creating a new impact doesn't necessarily have to start with an external intervention. The critical question here is: How much room for movement do the internal boundaries of the perceiver allow?

Isn't the capacity to notice these boundaries just as important as having a space for the perceiver's internal limits? I mean, even if there is an area within the boundaries where transformation can begin, if the perceiver cannot see it, wouldn't that area remain dysfunctional? In this case, the matter may not only be about the flexibility of the boundaries, but also about being able to recognize that flexibility.

As much as it's important for the perceiver to notice their boundaries, what they do with those boundaries after recognizing them is also significant. Awareness alone is not enough; if the perceiver cannot find a motivation to act on this awareness, those boundaries remain merely known but unchallenged walls. So, what shapes motivation—are they solely internal dynamics, or can it also be influenced by an external "incentive" offered by the perceived?

It may be inadequate to explain motivation solely through perceived or intrinsic dynamics. Perhaps what truly shapes motivation is the scope of action permitted by the context in which the perceiver finds themselves. For instance, if the context is completely closed off, no matter how much "incentive" is perceived, that motivation may extinguish without being triggered. So the critical question is this: Is it possible to widen the scope of the context, or is this area as fixed as the perceiver's limits?

Can the scope of context be considered independently of the triggering effect of what is perceived? In other words, sometimes what we call context can be a structure that is continuously reshaped by the perception dynamically. If the context of the perceiver is not rigid, then the perceived already has the capacity to expand that area; but who decides the limits of the influence of what is perceived? Is this boundary determined from within or from without the perceiver?

We're talking about broadening the perceiver's context or how the impact of the perceived shapes this context to what extent, but let's ask this: If what we call context is already a structure that is not fixed, constantly changing, and influenced by other factors, on what basis is this expansion effort made? In other words, when a context is broadened, who will define the boundaries of this new area? The perceived, or the perceiver's current capacity?

Perhaps it might be more interesting to discuss creating different meanings within the existing boundaries rather than expanding the boundaries of context. Expansion may not necessarily require a physical or visible change; being able to make a new "reading" within the current context by the perceiver is not a transformation in its own right?

In the current context, making a new "reading" could be another form of transformation, but doesn't this imply the assumption that the boundaries remain fixed? In other words, what kind of interaction occurs when creating new meanings collides with the visible effects of boundaries, as a function based on the subjective experience of the perceiver? Is a transformation that is limited to the internal playing field sustainable when faced with external influences from the context?

The issue of sustainability may change according to the weight of external influences. So, what determines whether an external influence is strong enough to completely obliterate the meanings created inside? To what extent can the perceiver keep their internal motivation "stable" against these external influences? Isn't stability, in fact, a limit in itself?

Stability may be a boundary, but isn't the flexibility of that boundary also variable? I mean, even if the external influence remains the same, does the response of the perceiver to that influence in the current situation always remain the same? Perhaps even within the same context, different meanings can be created at different times, because the perceiver's current state is not fixed. In this case, wouldn't the temporal change of the perceiver be the main determinant rather than the external influence?

The temporal change of the perceiver may be decisive, but is this change completely independent of the contextual external influences? Perhaps the issue lies as much in the structure of the context as it does in how much and in what way external influences leave an imprint on the perceiver. Is the perceiver's response truly a temporal change, or is it an adaptive response to external influences?

I think we should look at both the external influences shaping the context and the resistance or adaptability coming from within. An adaptive response reflects the flexibility level of the perceiver, but where does this flexibility draw its limits from? Is it independent of external influences, or is it a product of those influences?

If flexibility is shaped by external influences, how internalized can these influences be? That is, is the perceiver's reaction truly a reflection of their subjective capacity, or is it a "reflection" created within them by external factors? Perhaps what we call resistance is nothing more than determining the boundaries of this reflection.

Perhaps what we call resistance is not about defining the boundaries of reflection, but rather a continuous negotiation process between the areas created by those reflections. Wouldn't it be more explanatory to think of resistance not as a fixed boundary, but as a movement oscillating between external influences and internal responses? The subjective capacity we refer to likely emerges in this negotiation.

So is there a situation in this negotiation process where the "areas" are completely independent from each other? I mean, can a reflection arising from an external effect maintain its boundary without interfering with another area within? Or are all these areas already interwoven from the beginning? I think we need to clarify this.

If the fields are permeable, is this permeability the same in every case? That is, do some external influences intervene more while others remain only on the surface? Perhaps the issue lies in the nature of the external influence and the field it touches on the perceiver. In this case, permeability may not be a fixed characteristic but rather a situational outcome.

You say permeability is not constant, but that doesn't exclude the possibility that all fields are somehow interconnected from the start. Perhaps permeability is not a process, but rather a condition that manifests itself at different densities? Then we could also ask the question this way: is permeability an assumed "starting point" or does it emerge later within the context?

It seems more likely that permeability is a condition that is continuously reconstructed within context rather than a fixed starting point. Because as the context changes, so does the way external influence is perceived. If there were a fixed permeability, we would see the same reaction in every context, but this is not the case. This suggests that permeability itself flexes according to conditions and may even evolve.

Diving into the water without a tampon makes that permeability pretty obvious. Think about how much "binding" the external effect of the water creates inside. In this case, is that resistance your swimsuit fabric?

As much as the infiltration of seawater is an issue, so is the prevention of the internal liquid from leaking out. Perhaps here, it's not just about resistance or permeability, but rather a bi-directional interaction. So, in this interaction, is the pressure from the "outside" more determining, or is it the balancing effort from the "inside"?

Rather than comparing the balance of the interior to the pressure from the outside, it might be more accurate to think of the relationship between the two as a "flow." This is because completely controlling the entry of seawater or the exit of what is inside is very limited by human anatomy. The key question we should ask here is this: Is this interaction a natural adaptation, or is it a situation that needs intervention?

Perhaps when discussing this "flow" issue between the internal and external, we also need to consider the chemical composition of seawater. Do factors like the salinity or temperature of the water accelerate or slow down this interaction? Is what we call adaptation actually a result of the body's alignment with these differences?

Perhaps we also need to take the duration into account along with the chemical composition of the water. In other words, the length of time that one is exposed to that permeability can also affect the body's adaptation. Is the issue a short-term interaction or a long-term imbalance?

In discussing permeability issues, chemical structure, duration, and so on have been mentioned, but there's a simple truth: the microorganisms, salts, and whatever else in that water are not welcome at all. It's not about the body's adaptation; the risk of infection is what matters here. Just because we mentioned adaptation doesn't mean the immune system is working for free. Defense is already low during the menstrual period. Are you going to test it based on that?

Sure, while the microorganisms and chemical composition of seawater can pose an infection risk, we should also consider this: We shouldn't see the body as a constantly open "gateway". The vagina has its own defense mechanisms. The risk isn't eliminated, but it's also not certain that swimming in the sea will automatically be harmful. However, I think the duration and cleanliness of the water are critical here. Could a few minutes of swimming in a truly clean place really have a low chance of causing a serious issue?

How about trying a menstrual cup instead of a tampon? Would it cause issues in terms of protecting the inside and preventing leaks, or could it also pose a risk? Because it seems like it might not lead to the same "permeability" debate as tampons.

Even in places where the sea water is thought to be clean, the density of microscopic particles and bacteria can vary significantly. No protection can guarantee 100% safety without confirming the reliability of the water before discussing the container or buffer. Should I ask whether to choose a chlorinated pool or the sea?

While the cleanliness of water has been mentioned during menstruation, there's another issue: seawater is salty and this salt can disrupt the vaginal flora. Disruption of the flora increases the risk of infection. Entering without tampons doesn't just carry microorganisms; this flora issue adds extra weight. Is anyone thinking about this part?

I'm curious about this: we're only talking about the issue of taking something in from the sea when bodily fluids come into contact with seawater, okay. But what about what is released from the inside? How might the chemical composition of menstrual blood interact with the microorganisms in the sea? Are we disrupting that balance, perhaps?

You mentioned the interaction of blood with the sea, but I think there’s another aspect: When blood mixes with the sea, could it be a "nutrient" for the fish or other creatures in the water? Because it’s organic matter, after all. Are we causing such a cycle in that ecosystem? I'm curious.

Fish are fine, but we're missing a bigger question: Do sharks react to the smell of blood? Is it an urban legend or is there a scientific basis? If anyone has read about it, please share, because this could be a concern related to the sea.

Sharks' reaction to blood is not an urban legend, but the situation is a bit different when it comes to menstrual blood. Menstrual blood is not just blood; it contains tissues and other bodily fluids, and may not be a strong enough "attractor" to draw in sharks. However, it still depends on where you're swimming; in some areas, this risk is a real question mark. If you're near the ocean, I suggest doing your research.

There have been discussions about the issue of blood quantity in terms of the ecosystem, but no one has touched on how this blood is transported by the currents and movement of water within the sea, and what kind of impact it has there. In other words, it doesn't just dissolve and disappear in the dark at a certain point; it moves. How important is this balance? If anyone knows, please share.

When it comes to the part about seawater carrying menstrual blood and impacting different areas, I also need to add this: Do the bacteria carried with that blood or the biological substances it contains (like hormones) have an effect on other organisms? I think this situation can be more pronounced in enclosed waters. This is why chlorine is present in pools, but that "cleaning" factor is absent in the sea.

If you go in without a tampon, the movement of the water will already disperse the blood significantly, so it wouldn't create a situation intense enough to affect the ecosystem. But I've been thinking: We go through the spark to prevent the body from taking anything from the outside, okay. But could the irritation increase due to the salt in the seawater? There is already sensitivity during menstruation; has anyone ever experienced this effect?

There’s a detail regarding the irritation caused by salt in seawater: If there are micro-cracks or exposed tissues, the salt can cause not only irritation but also lead to further fluid loss. Is the body more sensitive to such an effect during menstruation? If anyone has experienced this, they might be able to provide a clear comment.

The biological effects of menstrual blood have been discussed, but let me add this question: Could there be metabolites of medications (like birth control, painkillers, etc.) used in the blood that is expelled from the body, and are marine organisms exposed to these? Has anyone heard of studies examining the effects from this perspective?

The saltiness of seawater already makes it difficult for some bacteria to survive, but there is a different type of microbial balance in enclosed waters or hot regions. Could the microorganisms released by menstrual blood actually have an effect in such waters? Has anyone seen specific research on this topic before?

You've said to examine the risk of sharks along the ocean coast, but it's important to understand this: Not all shark species respond with the same sensitivity. For instance, are tiger sharks or great white sharks more sensitive, or is that a too broad generalization? If there is a difference between species, do we need to look in detail depending on where we are going to swim?

If it's true that body fluids other than blood mix with water, do pH differences or chemical compositions affect marine organisms? For example, do plankton or other microorganisms respond to this "difference"? Because the pH of water is a crucial balance factor, is there any research on this?

They say that the saltiness of seawater creates a barrier against bacteria, but I thought about this: During the menstrual period, the vaginal flora already becomes imbalanced. So, is there a greater risk of disrupting the natural balance inside with seawater coming from outside? Could this open the door to issues like vaginitis? Can someone with experience in this area write about it?

If entering without a tampon mixes with the blood and water, could this somehow be transported to the bottom through gravity? Could the species living at the bottom be more intensely exposed to this chemical difference? I think we need to think comprehensively about this.

When entering without tampons, the temperature and density of the water can also be important factors. In warmer or less dense waters, blood and other bodily fluids can mix more quickly, increasing the likelihood of spreading more rapidly over a wider area. Do you think this spread rate makes a significant difference for marine organisms? Because the temperature of the water can also alter the metabolism of microorganisms and accelerate the dynamics of interactions.

We're discussing the effects of entering without tampons, but this detail has never come up: the possibility that waste other than blood can also produce an odor. How does this odor disperse in waves, and does it have an effect of attracting or repelling fish or other sea creatures? This could be more critical, especially in enclosed bays where the water is less renewed.

One effect of being tampon-free while entering the sea could be the following: Menstrual blood is not just blood; it also contains tissue fragments. Could it be that these tissue fragments can remain in the water for a while without dissolving? If so, has there been any research on how these physical particles are perceived by marine life (as food, a threat, etc.), or has anyone encountered such a situation?

But when entering without using a tampon, doesn't the buoyancy of the water and the direction of the water applied from the outside also affect? I mean, could it be like the natural flow inside reverses? Doesn't this harm the flora balance even more?

If seawater enters the vagina without a tampon, is there a possibility that the salt and microbes in the water could irritate the vaginal mucosa? Because I've heard of complaints of dryness or a burning sensation in the vaginal area after being in the sea for a long time. Does this effect vary from person to person, or is it a general risk?

You mentioned the seawater filling up, but on the other hand, the fluids inside could be drawn out due to body temperature. If something like reverse pressure is happening, how much seawater can actually enter? I think this mechanism needs to be clarified a bit more.

When swimming without a tampon, the biggest risk is not the microorganisms coming from outside, but rather the change in vaginal pH balance due to water entering. While the salt in the sea might theoretically be protective, excessively salty water can also irritate the mucosa. I also think duration is important: I believe the effect will differ between swimming for 5-10 minutes and staying in the sea for an hour. Do you have any observations regarding the duration?

Has the effect of plankton or more microscopic organisms in the water on vaginal flora ever been researched when entering the sea without tampons? Because the possibility that marine microbiota may intersect with human microbiota, leading to new irritations, came to my mind. Is there a chance that this risk could increase, especially during periods of intense plankton?

When it comes to entering without a tampon, there are discussions about its effects on vaginal flora, but something caught my attention: the temperature and salinity of seawater changes depending on the season and region. Could the combination of these two factors create combinations that are more harmful to the flora in some areas? For example, are lower salinity, warm seas riskier, or are those with high salinity and cold temperatures?

There's talk about a possible interaction between the pH of seawater and vaginal pH when swimming without tampons, but I would like to add something: Could heavy metals or chemical pollutants in seawater play a role in this interaction? For instance, could the risks for someone swimming near shores where factory waste is mixed or in port areas be more severe for vaginal flora? These would vary depending on the overall quality of the water. I'm sure some areas require more caution.

It feels a bit strange to me; we talk so theoretically, but who actually tests how seawater buffers or affects the balance of flora in practice? Does anyone have the experience of not using any buffer and going into the sea in different areas and saying, "I got irritated in this sea but not in that one"? These are theories, but is there anyone swimming with the information that "this sea is hostile to the flora"?

We've gone around so much in this theoretical framework, but one thing hasn't been questioned: How does the blood of someone menstruating affect the microbiota of the water the moment they enter the sea? Sure, you’re trying to protect your vaginal flora, but doesn’t the blood flowing outside create an environmental interaction? You’re adding an external "nutrient" to the marine microbiota, after all; what are the associated risks in that cycle? Nobody is discussing this.

One more thing: Could the water pressure slow down blood flow when entering without a tampon? After all, if the flow amount changes in the sea, this could bring the interaction of the microbiota and the risk of protecting the flora to a different dimension. Has anyone experienced this?

I think the main issue with entering without using a tampon is not whether the pressure of the water decreases blood flow during the menstrual cycle, but rather the prolonged contact with invisible particles in the water. If you're entering particularly in areas where the sediment at the bottom is disturbed, especially near the shore, the risk may increase. For example, could there be a difference between a cloudy sea and a crystal-clear cove? Has anyone ever paid attention to this?

You mentioned the risks in the areas close to the shore, and I immediately thought: there are already a bunch of microbes, fungi, etc., in the sand near the sea. As the water stirs, these must mix into the sea even more. So, if someone is disrupting the flora or is infected, it could also be coming from the microbes in that sediment. Has anyone experienced such a difference between sandy and rocky areas?

So, how important is the movement of seawater? Could the difference in microbiota between areas with strong currents, where the water is constantly renewed, and more stagnant, enclosed bays be significant for women's health? In other words, could the risk vary even within the same sea?

You mentioned the marine microbiome, and it reminded me of this: There is something called the sea's own "cleaning capacity." They analyze constant fecal samples and so on along the coasts, and I think this is valid not just for humans but also for the health of that ecosystem itself. For example, if there is too much waste in an area and the sea can no longer purify itself, the microbiological balance of that water might already be disrupted. In this case, is the sea to blame for harming your flora, or are we the ones who have already ruined that water?

Just as important as how the blood that is entered while menstruating interacts with the microorganisms in the sea is whether you carry an additional risk of infection due to your weakened immune system during that time. So, it's not just about the cleanliness of the sea, but how vulnerable you are in that environment. For those with a weakened immune system, the same water can yield different results. How have you taken this into account?

I'm curious about this: If you're going into the water without a tampon, how do you manage social concerns aside from biological risks? For example, don't we worry about whether bleeding can be noticeable when we're in the water or coming out? Water pressure might help to a certain extent, but wouldn't it be difficult to move comfortably without considering these practical details?

There is talk about the movement in the sea, the pressure of the water, etc., but I found one thing lacking: the salt concentration of seawater. Can salty water already have an antibacterial effect? For example, what is the difference in terms of infection risk when entering sweet water with a salt concentration of 3-4% compared to without using a buffer? Is there anyone who has experienced this or knows about it?

They say it's the salt ratio, but this thought just came to me: When we usually come out of the sea and take a shower, could it be that the soaps, shampoos, etc., we're using disrupt the microbiome even more? Maybe we should consider what we do afterwards more than the effect of seawater.

You mentioned the risk difference related to fresh water, but no one has touched on the issue of pools. Pools are cleaned with chlorine, but at the same time, they are a constant source of germs because they're ultimately a closed system. Isn't the risk of infection in a pool higher than in the sea during menstruation? Has anyone seen or experienced this?

You mentioned chlorine, but there is another different risk in pools: pH balance. A pool with imbalanced chlorine levels and pH balance can harm the skin and mucous membranes more. While salt in the sea may have a protective effect, chlorine and low pH can weaken the skin and create an environment more susceptible to germs. Has this difference affecting the mucous membranes between pools and the sea ever been tested?

People talk about the salt level or pH, but have you ever thought about this: During menstruation, the cervix remains slightly open, which can increase the risk of infection. So no matter how clean the water is, you’re forcing open a door. We jump to conclusions without even realizing whether it’s riskier with or without a tampon.

What about the difference in body temperature? It is said that the body is in a low-grade inflammatory state during menstruation; could the coldness of seawater trigger blood flow or this inflammation, leading to another risk? Is there any data on the effects of cold water during this period, has anyone looked into this?
