German sauna medical research shows that saunas were able to significantly reduce the incidences of colds and influenza among participants. As the body is exposed to the heat of a sauna and steam (in the case of traditional saunas), it produces white blood cells more rapidly, which in turn helps to fight illnesses and helps to kill viruses.In addition, saunas can relieve the uncomfortable symptoms of sinus congestion from from colds or allergies - especially when used with steam (tip: add eucalyptus to the water for added benefit and overall enjoyment). The steam vapor action helps to clear up unwanted congestion and is a wonderful aspect of the Finnish sauna experience.
