There has been an explosion of photobiomodulation studies over the past several years. I have previously reported results of studies that conclude photobiomodulation (light therapy) offers relief from neurological conditions such as Parkinsons and Alzheimers. These, however, are only a few of the conditions photobiomodulation studies conclude offer symptom relief.
Given the explosion of photobiomodulation studies recently – over 1500 studies alone published since 2025 – what conditions do the studies find photobiomodulation offer relief from symptoms?
Here is the list. Get ready to be surprised at the diversity of conditions photobiomodulation studies find this therapy to be effective.
- Mitochondrial function
- Cognition
- Parkinsons
- Alzheimers
- Traumatic Brain Injury
- Transmission of stem cells
- Macular degeneration
- Diabetic retinopathy
- Sperm motility
- Wound healing
- Inflammation
- TMJ
- Pain
- Cancer
- Alopecia
- Brain function
- Port wine birthmarks in infants
- Bone regeneration
- Carpal Tunnel Syndrome
- Cardiovascular disese
- Retinal Disease
- Sleep
- Spinal injuries
- Neuropathy
And this is not even an exhaustive list!
As you can see above, there is at long last compelling evidence that light therapy is a medicine of the future. This prediction is no longer an idle speculation on my part!
Vielight.com is the gold standard company that has been inventing photobiomodulation devices since 2016. They deliver light therapy with patented helmet and nasal applicators. There have now been 25+ published studies using their devices that address many of the conditions listed above.
Vielight offers a 10% discount on purchases – coupon code is healing4me. If users do not celebrate a welcome relief from symptoms, the company offers an 80% refund for units returned within 6 months of use.
Over the past two decades I have documented dozens of natural treatments that offer the opportunity to experience relief from neurological symptoms. My top recommendation in 2026 is the Vielight photobiomodulation therapy which has been documented in studies to produce consistent welcome relief from neurological conditions.
The company has humans (not AI) who answer the phone and answer your questions – 1-877-355-8012. They are a Canadian company but units are shipped from the USA to USA destinations so no tariffs are involved. https://www.vielight.com
