Cold Laser Therapy
Certain wavelengths of light have the ability to penetrate high-water content material such as animal tissue. This penetration allows the process of photobiostimulation on animal cells is similar to photosynthesis in plant cells whereby light sets in motion a chain of chemical reactions. In human tissue the resulting photochemical reaction produces an increase in the cellular metabolism rate which expedites cell repair and the stimulation of several systems: the immune, lymphatic and vascular.
LED (Light Emitting Diode) Therapy Our bodies use light as a source of energy. The energy from light has shown to help heal wounds. We often have more energy and feel better on bright sunny days.

NASA has been using LED color therapy for the past 30 years to accelerate
the healing process for their astronauts while in space. It was noted
that astronauts with wounds, broken bones or damaged muscles and cartilage
would not heal quickly unless LED therapy was applied.
The Space program is now looking at light energy to help heal astronauts.
In space, wounds are slow to heal. Muscles and bones become weaker from
time spent in space. Using light as a way to help the astronauts is
a good thing.
