Does photobiomodulation improve sleep?

Photobiomodulation is a therapeutic technique that uses wavelengths of red or infrared light to treat skin problems, such as wrinkles, scars and persistent wounds, as well as other conditions such as joint, tendon and muscle pain.

It releases energy at low intensity, without thermal effects and without ablation of the skin surface. These are two technologies that once you understand you can't help but use. Today it is used in every field and has radically changed many sectors, especially the medical one.

The researchers found it to be an effective way to treat muscle wasting, slow wound healing and bone density problems caused by weightlessness during space travel. And it is precisely in the medical sector that photobiomodulation and phototherapy have made it possible to achieve important results in the evolution of techniques for the creation of new devices.

Red light produces a biochemical effect in cells that strengthens the mitochondria (the powerhouse of the cell, where cellular energy is created). The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate).

The study Lights at night: does photobiomodulation improve sleep?, published on the Neural regeneration research, explained: "Sleep is a critical part of our daily routine. It impacts every organ and system of our body, from the brain to the heart and from cellular metabolism to immune function.

A consistent daily schedule of quality of sleep makes a world of difference to our health and well-being. Despite its importance, so many individuals have trouble sleeping well.Poor quality sleep has such a detrimental impact on many aspects of our lives;it affects our thinking, learning, memory, and movements.Further, and most poignantly , poor quality sleep over time increases the risk of developing a serious medical condition, including neurodegenerative disease.In this review, we focus on a potentially new non-pharmacological treatment that improves the quality of sleep.

This treatment, called photobiomodulation, involves the application of very specific wavelengths of light to body tissues.In animal models, these wavelengths, when applied at night, have been reported to stimulate the removal of fluid and toxic waste-products from the brain; that is, they improve the brain's inbuilt house-keeping function.

We suggest that transcranial nocturnal photobiomodulation, by improving brain function at night, will help improve the health and well-being of many individuals, by enhancing the quality of their sleep."
