The red light can penetrate through the skin and positively impact the mitochondriaTrusted Source within the body’s cells, helping to create more energy and allowing the cells to function better and repair themselves.

Co-lead study author Dr. Michael Powner, senior lecturer in neurobiology in the School of Health & Psychological Sciences at City University London said they decided to look at red light therapy as a way to help control blood sugar levels after reading a study from 2019Trusted Source highlighting that sunlight exposure could correlate with improved glucose metabolism.

“We explored this in bumblebeesTrusted Source and found that red light reduced systemic glucose after feeding,” Dr. Powner told Medical News Today. “This latest study clearly shows a translation of this to humans.”

“Red light is absorbed by mitochondria and helps them produce more energy,” he explained.

“It lubricates the energy-making machine. But in producing more energy this way they need more raw material and this is largely glucose. They take this out of the blood.”

 
I remember my nan using a red lamp back in the 1970s. Supposed to have “health benefits?” (Not sure what, she was in her 70s & I was just a kid. Some sort of pain relief?) could be on the infrared spectrum? I do remember it chucked out a fair bit of heat with it angled at her arm or shoulder. (She hated doctors.)
 
For years and years I always had a red bulb in my bedside lamp, but these days it's a soft glow led bulb. I think I might have a couple of leftover red ones in the cupboard. If so, with my wife being the other side of the world at the moment, I might swap bulbs for a while.
