What does science say about red light therapy?

Red light therapy, also known as photobiomodulation, is a non-invasive technique that has recently received significant attention for its potential in various areas, including: skin and hair care, hormone balancing during menopause, sleep quality, recovery after physical exertion, mental health, reducing inflammation, eye health, strengthening the immune system, improving blood circulation etc.

Effects on skin and hair

  • Studies have shown that red light therapy is a safe and effective alternative for promoting hair growth. 3 9It also stimulates the production of collagen and elastin in the skin, which helps restore the skin barrier and reduce inflammation. 5 7.

Hormone balancing

  • Red light therapy can help regulate melatonin levels, which is important for hormone balance and sleep quality. 1May ease menopause symptoms Balance hormones so the body functions as it should

Better sleep

  • Studies show that red light therapy can improve sleep quality and increase melatonin levels, which is important for preventing sleep disorders. 1 4.

Faster recovery

  • Red light therapy can help you recover faster after exercise by improving blood circulation and reducing inflammation. 1 6.

Mental health and concentration

  • Red light therapy can improve mood and reduce sleepiness, especially during the winter months when natural sunlight is lacking. 4.

Reducing inflammation

  • Red light therapy is effective in reducing inflammation and oxidative stress, which can help treat various skin conditions. 2 7.

Eyes

  • Red light therapy may have positive effects on eye health by reducing inflammation and oxidative stress 6.

Immune system

  • Red light therapy can boost the immune system by promoting cell growth and reducing inflammation 6.

Blood circulation

  • Red light therapy can improve blood circulation, which is important for faster recovery and overall health improvement. 1 6.

Red and near infrared light: what's the difference?

Cells benefit most when using red and near-infrared light wavelengths.

Effects on the bodyBiostimulatorBiostimulator
Body reactionMore cellular energyMore cellular energy
Operating areaAt the surface level (skin, scars, reduced swelling, hair) At a deep level (muscles, bones, joints and organs)

How does it work?

ATP provides the fuel that each cell needs to perform all of its functions, including regeneration and healing.

Red light and near-infrared light stimulate mitochondria. These wavelengths of light cause your mitochondria to produce more energy in the form of ATP (adenosine triphosphate).

Conclusions

Red light therapy is a promising non-invasive form of treatment that can improve health and beauty in a variety of ways. It is effective for hair and skin care, hormone balancing, sleep quality, recovery from exercise, mental health, reducing inflammation, eye health, strengthening the immune system, and improving blood circulation.
