Winter swimming

outdoor swimming during winter, often with ice

Winter swimming is the activity of human swimming during the winter season, typically in outdoor locations, or in unheated pools or lidos. It is done mostly for health benefits.[1] Many winter swimmers swim with standard swimming costumes rather than with wetsuits or other thermal protection.
