These chemicals can be irritating if swallowed.

Chemical byproducts – Chlorine is often used to disinfect pool water, but it can react with organic matter to form disinfection byproducts, like chloramines.

These organisms can cause infections if ingested.

Bacteria and parasites – Pools can harbor harmful microorganisms, such as E.

Pool water typically contains various contaminants, including:

However, it’s essential to know the potential health risks associated with ingesting pool water and how to minimize water ingestion. Swallowing pool water is a common occurrence, especially for those who are new to swimming. Swallowing Pool Water: Is It Harmful To Your Body? So to stay hydrated, we must drink enough water before, during, and after swimming.

Our skin prevents water absorption but not fluid loss. Swimming requires sufficient fluid intake to stay healthy. Your kidneys detect this as an increase in blood volume and work to clear excess fluids, causing more frequent urine. External pressure compresses your body, forcing blood from your extremities to your torso. Swimming increases water pressure, especially when you dive deeper. Moreover, water’s hydrostatic pressure raises blood pressure.

Constriction raises blood pressure, which reduces vasopressin (antidiuretic hormone or ADH) synthesis. Water pulls heat from your body, constricting blood vessels near your skin to retain warmth. This is caused by water pressure and temperature. Immersion diuresis occurs when you’re underwater. I know, you might be wondering – swimming typically makes you want to pee. “ Stratified squamous epithelium ” cells in our skin block water from entering inside. Kind of like how some, but not all, fish… fart.Even while you’re swimming your skin remains protected from water absorption. The saltwater-soaked ones will still be crunchy, but the freshwater ones, having absorbed water, will be softer. Want to see osmosis for yourself? Submerge some potato slices in salt or fresh water overnight. Saltwater fishes’ kidneys also help to filter out some of their salt. In freshwater fish, the cells constantly pump salt in, and in saltwater fish, they constantly pump salt out. To stop the exploding fish phenomenon, their gills have special cells that selectively pump salt in, or out of their blood. They can’t just allow the water to diffuse freely through their gills the saltwater fish would shrivel up and the freshwater fish would explode! Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.īut fishes’ bodies, just like ours, need a certain concentration of salt to function best.

The opposite is true for saltwater fish.Īs well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. In the case of freshwater fish, their blood and bodily fluids are much saltier than the water they swim in, so water will flow in through their gills. It serves to equalize the concentrations in the two areas. Osmosis is the flow of water across membranes from areas of low concentration of dissolved things (solutes) to areas of high concentration. Can’t they just, I don’t know, absorb it or something?įish do absorb water through their skin and gills in a process called osmosis.

Nonetheless, it seems silly that an underwater creature should have to drink. Without it, the chemical reactions that take place constantly in our bodies would have no solvent and we would die. Our bodies and fishes’ (yes, fishes is a grammatically correct plural form of fish) bodies as well need water.
