Red light therapy, an integrative photomedicine approach, may have wellness benefits, from boosting brain health to healing wounds.
1. Helps Address Skin and Hair Concerns, From Acne to Wrinkles and hair loss
2. Lessens Pain 
There’s a specific protein on the surface of the neuron that when it absorbs light, it reduces the ability of the cell to conduct or perceive pain. Past research shows that LLLT may be useful to control pain for those who have neuropathy (nerve pain, which is commonly caused by diabetes, according to the Cleveland Clinic). 
3. Helps With Sports Performance and Injury Recovery
Red light stimulates your mitochondria (the energy powerhouse of cells), triggering an enzyme that drives up ATP (the “energy currency” of the cell according to StatPearls), which — in the end — benefits muscle growth and repair.
4. Helps Brain Health 
There are striking studies that show photobiomodulation treatments [can potentially] improve neurocognition. PBM may not only reduce inflammation, but may also improve blood flow and oxygen to form new neurons and synapses in the brain, which may be helpful in people who have suffered traumatic brain injuries or strokes, according to an article published in the Journal of Neuroscience Research in April 2018. 
5. Improves Wound Healing
From skin to oral wounds, red light may be used to improve healing.
6. Improves Circadian Rhythm and sleep patterns
Red light stimulates the production of serotonin, which is important for regulating mood and sleep. It also helps to reduce the production of cortisol, a stress hormone that can interfere with sleep. So while red light therapy does not provide the same benefits as natural sunlight, it can still be beneficial for sleep.
