Question

Can regulated sunbathing be an option to avail infrared rays for physical healing?

Answer 1

Old treatment for a head cold, to dry the sinuses, great natural source for Vitamin D.

Sun is the best way to sterilize pet cages- takes 2 weeks after they have been washed. Why can't it be applied to humans, just don't burn  severally and end up with sun poisoning.

Out door treatment was used in the long ago past for TB.

Anyway it is more fun to sit in the sun that be in a tan tube.
