A Must Have for Heart Health: Red Light


In the western world, people are spending most of their waking hours amidst artificial light . We work in office settings amidst artificial fluorescent lighting while staring all day at devices that emit blue light. We then go home to watch television, read emails or continue to work from our devices, leading to more blue light exposure. Blue light is a wavelength we need but nowhere near the amount we are all generously granting to ourselves.

The problem is that the many LEDs (blue light emitting diodes) disrupt our circadian rhythms or our biological clocks. Misalignment of circadian rhythmicity is observed in numerous conditions, including aging, and is thought to be involved in the development of age-related disorders, such as depression, diabetes, hypertension, obesity, and cancer.

What Is Red Light Therapy

Red light therapy or photobiomodulation involves exposing cells or tissue to low levels of red and near infrared (NIR) light. It involves having low-power red light wavelengths emitted directly through the skin. This treatment is now FDA cleared for conditions like chronic joint pain and slow to heal wounds. Red light wavelengths, therefore, affect bodily cells on a biochemical level by increasing mitochondrial function – the ability to produce cellular energy.

Low levels of red light can be effective for a variety of therapeutic purposes, including:

Disrupted Sleep Patterns & Heart Disease

Various studies document that blue light exposure will significantly suppress melatonin production, important in the initiation of sleep. This then increases the amount of time it takes to fall asleep and reduces the quality of sleep.

The American Medical Association stated,

“In addition to its impact on drivers, blue-rich LED streetlights operate at a wavelength that most adversely suppresses melatonin during night. It is estimated that white LED lamps have five times greater impact on circadian sleep rhythms than conventional streetlamps. Recent large surveys found that brighter residential nighttime lighting is associated with reduced sleep times, dissatisfaction with sleep quality, excessive sleepiness, impaired daytime functioning and obesity.”

Poor Sleep’s Impact on the Heart

  • Sleeping less than six hours a night dramatically increases your risk of insulin resistance, which is at the core of most chronic diseases, especially heart disease.
  • High blood pressure
  • High blood cholesterol
  • Diabetes

Benefits of Red Light Therapy for The Heart

  • Stem-cell production and healing of heart cells post heart attack
  • Stimulating collagen synthesis and fibroblast formation, anti-inflammatory action, stimulation of energy production in mitochondria, and even stimulating DNA repair
  • Increased circulation and the formation of new capillaries
  • Suppression of  inflammation and production of inflammatory cytokines and dramatically reduces inflammation throughout the body
  • Reduction of ———-studies reveal consistently positive effects of red light therapy by reducing the size of the damaged area in heart attacks up to 76%
  • decreasing inflammation and scarring, and accelerating tissue repair of the heart


Red light therapy has been proven in the literature to show many benefits as an anti-inflammatory treatment in several disease conditions even when inflammation is a secondary consequence, such as in a heart attack. The benefits of red light therapy for improving overall health are astounding: if you have access to receiving this therapy go for it! We at Natural Heart Doctor recommend the Mito Red Light Therapy Device. It is a third-party tested device with the highest power on the market made affordable and effective!
