A saunas’ dry heat (which can get as high as 185° F) has profound effects on the body. Skin temperature soars to about 104° F within minutes. During a 10-20 minute sauna session, your heart rate increases by 50-75%. This provides the same metabolic result as physical exercise. There is a nominal effect on blood pressure because the heat also causes blood vessels in skin to expand to accommodate increased blood flow.
Blood vessels become more flexible and there is increased circulation to the extremities. During a sauna, blood flow to the skin increases to as high as 50-70% of cardiac output (compared to the standard 5-10%). This brings nutrients to subcutaneous and surface tissue resulting in glowing healthy skin.
*****When taking a sauna, skin temperature rises to 40°C (104°F) and internal body temperature rises to about 38°C (100.4°F). Exposure to the high heat creates an artificial fever state. Fever is part of the body’s natural healing process. Fever stimulates the immune system resulting in increased production of disease fighting white blood cells, antibodies and interferon (an anti viral protein with cancer fighting capability).*****
The steam is only affecting the head. So would we get the same benefits as a sauna? Does the temperature of one body part heat up the rest of the body? If not, then the steam treatment isnt getting the same benefits as a sauna gives becuase the sauna heats up the whole body. And we need the heat in order to make a fake fever so the immune system can heal our lips faster.
