The Science: How Infrared Heat Affects the Body

Can a Sauna Kill the Flu Virus? The Science
Let’s answer the scientific question in question: Will a sauna kill the flu virus inside the human body?
The answer is largely no. While the influenza virus is sensitive to heat (killed at temperatures above 167degF or 75degC), your body cannot get to those internal temperatures safely. If your core body temp reaches 107 degrees F, you are in a fatal situation of brain damage.
The misconception stems from the fact that the purpose of a fever is to make the environment less hospitable to the virus. An infrared sauna triggers a fever, but it does not “cook” the virus to death. It only aids in the immune response (when used properly) or interferes with it (when used during a high fever).
Summary: Should You Do Infrared Sauna When You Are Sick?
Let’s conclude the verdict for using infrared sauna when sick:
- Can I use infrared sauna when I am sick with a cold? Yes, generally safe and beneficial for congestion.
- Can I use infrared sauna when I am sick with flu? No. The risk for dehydration and overheating is too high.
- Is Good to infrared Sauna when Sick with Fever? Never.
- What about a far infrared sauna when you are sick? The same rules apply. Far infrared is more penetrating and can feel soothing on aches, but is more hazardous if you are running a fever.
The best infrared sauna when sick with flu is no sauna at all – rest and fluids are better. But for a nagging winter cold, a gentle session may be just the ticket to clear your sinuses and relax your body.
