Is infrared really safe?
Absolutely. Infrared light energy is beneficial and not damaging to the body. Infrared has been researched and used in medical practices for many years with Far Infrared heating used in hospitals to warm newborn infants. Sports medicine has long accepted and used infrared to promote healing of sprains and strains. NASA has also concluded after lengthy trails in the 1980’s that infrared therapy is the best way for astronauts to maintain cardiovascular fitness on long cramped space flights.
