2. An infrared sauna uses infrared heaters to emit infrared
radiant heat which is absorbed directly into the human
body, unlike traditional saunas which heat the body
indirectly via air or steam. Different radio waves have
different effect on human body.
4. X-Rays
These rays help us to see into
our bodies to check whether
we need medical attention
or not. When doctor takes
x-ray what he is doing is
shooting x-ray wavelengths
through our body onto a
film on the other side.
These rays are very harmful
if uncontrolled.
9. Radio waves
Radio and wire transmission.
Longest and less frequent wavelengths
safe for human beings
10. As we discussed different wavelengths have different
effect on our body. So Infrared Sauna uses different
radiations to directly absorb heat into human body.
