Light Sensitivity - Individuals with rare
conditions causing extreme sensitivity to
light or who have previously reacted to red
light therapy should avoid its use.
Fever or Infection - There is a theoretical
risk that the use of red light therapy can
worsen existing hyperthermia caused by
fever or infection.
Systemic Lupus Erythematosus (SLE) - SLE
can cause skin sensitivity, increasing the
risk of a reaction to red light therapy.
Severe Bleeding or Blood Loss - Some
research suggests that red light therapy
may slow the body’s ability to stop
bleeding.
Use of Photosensitizing Medications -
Medications that increase sensitivity to
light may increase risks of sensitivity to red
light therapy.
Tattoos - Red light therapy may cause
cosmetic defects to body art, especially
body art that uses red inks may be prone
to fading when exposed to intense red
light. The tattoo ink may also cause
uneven absorption of red light, causing
therapy to be less uniform.
Dark skin pigmentation - The effect of skin
pigmentation on red light therapy is still
being studied. Those with darker skin
tones may find that their skin absorbs
more light, making it warmer than those
with lighter skin tones would experience. A
smaller amount of red light may actually
reach deeper tissues, however, this effect
is not likely to be large.
