Why Do Periods Stop in Water?

Published in Women's Health 1 min read

The sensation of periods stopping or lessening in water is primarily due to water pressure, but it's not a complete cessation.

Here's a breakdown of why this perception occurs:

  • Water Pressure: The water pressure surrounding your body can counteract gravity, potentially reducing the flow. This is more noticeable in deeper water. However, this pressure doesn't completely stop the flow.

  • Muscular Contractions: Being in water, you're likely moving and engaging your abdominal muscles. This movement can sometimes increase the flow due to the added pressure.

  • Perception vs. Reality: The blood released in water is diluted quickly, making it less visible. Therefore, you might not perceive the period as actively flowing, even if a small amount is still being released.

Key takeaways:

  • Periods don't actually stop in water. The flow may be reduced or less noticeable.
  • Water pressure plays a role in potentially slowing the flow.
  • Movement can sometimes increase the flow.
  • Sanitary products like tampons and menstrual cups are still effective and recommended for managing your period while swimming.
