This would be an apparatus that looks like a tanning
bed, but instead of UV lamps it would have longwave
infrared lamps, and its purpose would be to bathe the
user in longwave infrared light which can accelerate
healing for the body. Even NASA has researched infrared
light therapy as a way
to keep astronauts in strong
health and to help heal their injuries far from home.
The user could relax and sleep in the Infrared Therapy
Bed and wake up feeling very refreshed and vigorous.
This might even be good for business travelers suffering
from jet lag and other travel fatigue. It would also be
good for the elderly, to help against the effects of old
age.
The user would not have to wear eye-protection while
using the Infrared Therapy Bed, because not only will
longwave infrared rays not harm the eyes, but they
would actually help to stimulate cellular metabolism to
rejuvenate the eyes, and help stave off things like
macular degeneration.
