Swimming in the ocean is sure fun and it would be quite refreshing. But, research revealed that swimming in the ocean alters the skin microbiome and increases the chances of skin infection. This research was narrated at the meeting of ASM Microbe 2019. "Our data demonstrate for the first time that ocean water exposure can alter the diversity and composition of the human skin microbiome," said Marisa Chattman Nielsen, the lead author.
They can even lead to respiratory illness, gastrointestinal issues, skin infections along with ear infection. A survey has been conducted and tests are done for all those who were interested in swimming in the ocean. Tests are conducted after a ten-minute swim, after sic hours post-swim and 24-hours post-swim. Six hours post swimming told that the microbiomes started to revert to their pre-swim composition. Vibrio species (causes cholera) were found in most of the people after six hours post-swim.
