How does red light therapy work?

Red light is thought to work by producing a biochemical effect in cells that strengthens the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate).

By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.

All living things need to make ATP cellular energy to function and survive, and nearly all living things rely on natural light to power this process in our cells every day. Red and near infrared wavelengths of natural light stimulate the mitochondria in your cells, the powerhouses responsible for taking light, oxygen, and the food we eat—and turning it into usable energy for our bodies through the process of cellular respiration.

In addition to making more ATP energy and performing at higher levels, here are some of the other basic principles of red light therapy:

Antioxidants Reduce Oxidative Stress: Natural red and near infrared light helps promote antioxidant production, which plays a central role in reducing the oxidative stress associated with cell injury and things like muscle fatigue and joint pain & inflammation. Antioxidants also increase the production of heat proteins—special enzymes that help protect cells from stress and early death.

Increased Circulation: Studies have also identified an increase in circulation following red light therapy, indicating tissues are receiving more oxygen and other nutrients important for healing—while also ridding themselves of toxic byproducts.

Ever since the initial experiments in space, there have been hundreds of clinical studies and thousands of laboratory studies conducted to determine if RLT has medical benefits.

Many studies have had promising results, but the benefits of red light therapy are still a source of controversy. The Centers for Medicare and Medicaid Services (CMS), for example, has determined that there isn’t enough evidence to show that these devices are better than currently existing treatments for treating wounds, ulcers, and pain.

Basics of a Red Light Therapy Treatment

A high-quality red light therapy device like a Bestqool uses medical-grade LEDs to deliver concentrated wavelengths of natural light to your skin and cells, without dangerous UV rays or excess heat. All you have to do is sit or stand near a device for 10-15 minutes a day to charge your cells. The more surface area of your body you can cover, the more your cells absorb natural light, and the more full-body benefits you can expect to see with consistent use.
