Light Therapy

Here you can find links to research projects conducted into the effectiveness of low light therapy as a treatment for a variety of conditions.

In summary, laser therapy normalizes our body’s cellular functions by restoring disabled mitochondrial ATP production. This in turn leads to a cascade of processes that increases the recovery of damaged or poorly functioning tissue. The main categories of recovery are:

  1. Nerve Function (stimulation, healing, and pain reduction)
  2. Inflammation (takes the chronic inflammation into the acute phase)
  3. Wound Healing(inflammation, proliferation, maturation)
  4. Circulation (vasodilation and microcirculation)

Here is the list of research backed evidence to support the use of Low Light Therpay…
