Radiant heat is also called Infrared
Energy (IR). The infrared segment
of the electromagnetic spectrum
is divided into 3 segments by
wavelength, measured in microns
or micrometers (a micron = 1/1,000,000
of a meter); 0.076 ~ 1.5 microns
= near or close; 1.5 ~ 5.6 = middle
or intermediate; 5.6 ~ 1,000 =
far or long wave infrared. The
infrared segment of the electromagnetic
spectrum occurs just below or
to red light as the next lowest
energy band of light. This band
of light is not visible to human
eyes but can be seen by special
cameras that translate infrared
into colors visible to our eyes.
We can, however, feel this type
of light that we perceive as heat.
It has nothing to do with either
ultraviolet radiation (which gives
you a sunburn and damages your
skin) or atomic radiation (the
kind from a nuclear bomb). Radiant
heat is simply a form of energy
that heats objects directly through
a process called conversion, without
having to heat the air in between.
Our sun produces most of its energy
output in the infrared segment
of the spectrum. Our atmosphere
has a window± in it that
allows IR rays in the 7 ~ 14 micron
range to safely reach the earth's
surface. When warmed, the earth
radiates infrared rays in the
7 ~ 14 micron band with its peak
output at 10 microns.
According to Dr. Tsu-Tsair Oliver
Chi in his summation on the mechanism
of actions of infrared devices
tuned to the human body, these
rays are selectively absorbed
by the tissues needing a boost
in their output. The internal
production of infrared energy
that normally occurs within our
tissues is associated with a variety
of healing responses and may require
a boost to a maximal level to
insure the fullest healing response
possible in a tissue under repair.
Harmlessly. This phenomenon is
called ¡°resonant absorption.¡±
The sun is the principal source
of radiant energy that we experience
Have you ever been outside on a
partly cloudy spring day of about
50¡× and felt quite
comfortable when the sun was suddenly
obscured by a cloud? Although
the air temperature had not had
time to drop, you felt chilled,
as the cloud would not let the
warming infrared rays through
to reach you.
Our palms emit infrared energy
at between 8 ~ 14 microns. Palm
healing, which has a 3,000 year-
old tradition in China, has been
based on the healing properties
of these natural infrared rays.
The Yogis of India also use such
palm healing and recommend it
especially for relieving eye strain.
Sauna use has been popularized
by the Finns whose old religion
used it as a ceremony for mental,
spiritual and physical cleansing.
This religion came with the Finns
when they migrated from an area
northwest of present day Tibet,
between 5,000 ~ 3,000 year BC,
to their present location in Finland.
The Chinese researchers consider
the band from 2 ~ 25 microns as
the most therapeutic.
