There is a common misconception that your menstrual flow stops when you get in the water, but the reality is a bit more complex. This article explores how being in water affects your period, why it may seem like your flow stops, and answers other questions you may have about swimming while menstruating.
Your Period, Underwater
Contrary to popular belief, water does not stop your period. Whether you’re in a pool, river, or ocean, your uterus will continue shedding its lining as usual, unless there is an underlying medical issue. So, while you can’t avoid your period by being submerged in water, the flow of blood may appear to halt temporarily.
What’s the Science Behind It?
When your body is in water, the pressure from the water counteracts the force of gravity that normally helps blood flow out of your body. This buoyant force can make it seem like your period has stopped, but it’s just a temporary effect.
If you engage in activities that exert force on your body, like coughing or sneezing, the pressure from these actions can sometimes overcome the water’s resistance and let some blood out.
Tips for Swimming on Your Period
Swimming may help alleviate PMS-related symptoms
A study from 2018 found that swimming can reduce PMS symptoms, including cramps. So, if you’re not up for intense exercise, a relaxing swim may help ease your discomfort.
Don’t worry about being unsanitary in the pool
Most public pools are treated with enough chemicals to prevent any sanitary concerns while swimming on your period. Additionally, the amount of blood lost during menstruation is minimal, so leaks are unlikely.
Sharks won’t attack you (just because of your period)
Contrary to popular myths, sharks are unlikely to attack you just because you’re menstruating in the ocean. While sharks may be able to detect blood, they also sense other bodily fluids, so the risk of an attack is low.
Skip out on panty liners and pads
If you’re swimming on your period, it’s best to avoid panty liners and pads as they can become waterlogged and lead to leaks. Instead, consider using tampons or menstrual cups, which are safe for water activities and provide reliable protection.
