This is very different than a shower or even a pool, because those water sources usually have a low concentration of bacteria,” Chattman Nielsen said.
#Does your body absorb water when you swim skin
“Ocean water is a unique exposure, because not only does it wash off normal skin bacteria, it also deposits foreign bacteria onto the skin. They had also completely changed from the microbiota present before their swim.Īt six hours, their microbiomes began to return to what they were before swimming. But after their swim, the microbiome communities of all the participants were similar. They were then swabbed six hours and 24 hours after their swim.īefore they entered the water, the participants had different communities of bacteria on their skin. The participants were swabbed on the back of their calf before entering the water and swabbed again after they swam for 10 minutes and dried off completely. In undertaking their study, the researchers from UC Irvine enlisted nine volunteers who hadn’t used sunscreen, had infrequent exposure to the sea, hadn’t bathed in the past 12 hours, and hadn’t taken antibiotics in the previous six months. Other studies have also found that changes in the microbiome may make a person more vulnerable to infection.
Previous studies have found associations between swimming in the ocean and infections, due in part to poor water quality at beaches from wastewater or stormwater runoff. This would indicate that if pathogens are present in the water, they may also be present on the swimmer’s skin even 24 hours after they swim,” Marisa Chattman Nielsen, MS, a PhD student at the University of California, Irvine, and lead author of the study, told Healthline. Organisms present in the water were still detected on the skin 24 hours after swimming. “Participants swam in relatively clean water, and still their microbiomes were significantly different after swimming than they were before. However, experts interviewed by Healthline say there really isn’t any reason to avoid the beach this summer.Īt the annual meeting this weekend for the American Society for Microbiology, scientists shared research that showed exposure to ocean water through swimming changes the composition and diversity of a person’s skin microbiome. Your skin microbiome is altered after you swim in the ocean, according to research presented at a conference on microbiology. For more information on the skin and wrinkles, visit the links on the next page.Share on Pinterest Experts say you probably don’t have to shower after swimming in the ocean, but it’s still not a bad idea. Unlike wrinkles you get when you're older - which are usually the result of sun damage, dry skin or loss of fatty tissue - those caused by water absorption are temporary and should go away soon after you dry off. This makes them especially susceptible to wrinkling in water. Researchers are studying other theories for what might help cause the wrinkling, such as the whether the constriction of blood vessels is related to it.īut if most of your body is submerged in the water, why do these wrinkles occur only on the hands and feet and not on other areas? Because they get so much use, the palms of your hands and the soles of your feet have thicker skin - and therefore a thicker layer of keratin - than the rest of your body. As a result, the stratum corneum wrinkles to give the temporary new surface area someplace to go. As the dead cell layer expands, it begins to take up more surface area, but it's still connected to the living cells beneath and doesn't have anywhere to go. These dead keratin cells in the stratum corneum absorb water easily and start to swell after extended periods in the water, but the living keratin cells deeper in the skin do not.
