A brief, 30-minute session in a sauna, especially when followed by a short cold shower, can temporarily activate your immune system. Research from Finland indicates that the heat of the sauna, in combination with the shock of cold water, led to an increase in all types of white blood cells circulating in the blood. This surge includes critical infection-fighting cells like neutrophils and lymphocytes.
