What are the contraindications for light therapy treatments?

If you are referring to the light therapy used as a (questionable) treatment for Seasonal Affective Disorder (severe winter depressions), the most apparant contraindications deal with potential ocular (eye) damage.

The full-spectrum devices have frequencies at both the red (infrared) and the blue (ultraviolet) ends of the spectrum that can cause various eye problems. Also, especially with the "blue enhanced" devices, overexposure to ultraviolet rays could cause skin problems including the possibility of skin cancer in severe cases.

Since people with this ailment (SAD) are likely to be Vitamin D deficient, you might be better off to take cod liver oil or halibut liver oil supplements through the winter months, and perhaps also calcium supplements, and then find something to do to keep from sleeping all winter.

What is contraction and relaxation?

  • Nerve impulse, or electrical signal, travels down the nerve to the terminal to cause the release of the neurotransmitter acetylcholine (ACh).
  • ACh diffuses across the neuromuscular junction and binds to the receptor sites.
  • Stimulation of the receptor sites causes an electrical impulse to form in the muscle membrane. The electrical impulse travels along the muscle membrane and penetrates deep into the muscle through the T-tubular system.
  • The electrical impulse stimulates the sarcoplasmic reticulum to release calcium into the sarcomere (a contractile unit of a mofibril) area.
  • Calcium allows the actin, myosin, and ATP to interact, causing crossbridge formation and muscle contraction. This process continues as long as calcium is available to the actin and myosin.
  • Muscle relaxation occurs when calcium is pumped back into the sarcoplasmic reticulum, away from the actin and myosin. When calcium moves in this way, the actin and myosin cannot interact, and the muscle relaxes.
