From what I understand an IR sauna only emits on the IR and FIR range (roughly from 4 to 1000 microns wavelength)Green_Manalishi said:Hi all. I have two questions.
The benefit we get from the far infra red radiation in the sauna (apart from the sweating) is the same as if one would stand directly in the sun's light? The radiation is the same, and I remember reading in a a book about someone who travelled to China in which the author said one advice that was given to her by a Chinese "popular medicine doctor" was that there was nothing better for the body then standing naked in the sun for one hour every day.
The sun emits on a much broader range including UV, IR and visible spectrum.
So there is a qualitative difference between sun emissions and FIR sauna emission.
There might also be a quantitative factor (that I'm unable to calculate) knowing that a FIR sauna generates roughly 300 W of IR radiations that are beamed on the whole skin.
Maybe in order to get such amount of IR radiation from the sun, one should spend a lot of time tanning and/or would receive a lot of harmful rays ?
This being said this sun and sea water cocktail reminds me of something. Where I live (French Mediterranean coast) there is this specific population of retired people who spend their time on the beach. They keep tanning and swimming and actually they seems very healthy and energetic.
I'm wondering if it's linked to their high level of IR and magnesium absorption ?
