Saunas are fromFinland; the word means a room made of wood. Temperatures in a sauna range from 80 to 100° C, with an ambient humidity of less than 30%. Each cycle in the hot room lasts from 8 to 15 minutes, following by a short period to cool off under the shower or in a separate cold plunge. The interplay of hot and cold stimulates bodily functions, especially circulation and blood flow. In addition the body’s own powers of resistance are mobilised, activity of the heart is stimulated and blood pressure regulated.
