Red light exposure
For mitochondrial health and light exposure
The experts we follow agree on this.
Red light exposure supports skin and mitochondrial health, and helps prepare the body for sun exposure.
Who is behind it
Voices including a Princeton-trained molecular biology PhD, a GP with a Master of Public Health and a clinical nutritionist.
How strong the research is
Backed by some published research, and by what the experts see in practice.
In their words
“42 percent of the light from the sun is red light and this is really important for counteracting all the blue light”
a molecular biology PhD
Red light exposure protects skin from sunburn and supports mitochondrial function.
Red light preconditions the skin for UV exposure and is essential for maintaining skin health and melanin function.
Artificial blue light inhibits mitochondrial water production, while red and near infrared light promotes it, supporting cellular voltage and health.
Red light liberates nitric oxide from cytochrome C oxidase in mitochondria, which supports water production and may help lower eye pressure.
Physical closeness and fireside exposure provide infrared energy which supports healing and energy balance.
Red light triggers biological cascades that calm the nervous system according to Nobel Prize-winning science.

How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Backed by some published research, and by what the experts see in practice.
