@Mauritio said in Just 1 minute of red light is effective:

Just one minute in the morning was enough to improve eye health in a study . It only worked in the morning as far as I remember. There seems to be something about red light in the morning being very healthy

Some time ago, I posted about it on RPF here.

Below is that post screenshot as I don't know whether the link is generally usable.

I definitely wouldn't base my decision or research on what a random TikToker has to say, even if they pitch out math as their evidence.

In a situation like this my suggestion is to hunt down more professional research.

As for infra red vs narrow range red vs incandescent, there's a few differences obviously, each one has it's rightful place for certain folks.

The greatest effects came from variations that included blue light (on the right side) and it would be minimal with heat lamps.

Ultraviolent light also affects nitric oxide levels. Based on what's shown above, the typical durations recommended for sunlight exposure would fall within the length needed to level out the effect from red light.

Red or infrared before blue light didn't lessen the impact of blue in isolation, but afterwards they did. It's only helpful that exposing the skin to longer wavelengths before ultraviolence can minimize damage:

@NangaParbat also
"Irradiation by ultraviolet, gamma, or x-rays, and even by blue light, is damaging to mitochondrial respiration. All of the ionizing radiations produce immediate and lingering edema, which continues to damage metabolism in a more or less permanent way, apart from any detectable mutagenic actions. The amount of water taken up following irradiation can be 20% to 30% of the normal weight, which is similar to the amount of swelling that intense work produces in a muscle, and to the weight increase under hormonal imbalances. The energy changes produced by irradiation in, for example, the heart, appear to accelerate the changes produced by aging. Since unsaturated fats accumulate in the respiratory system with aging, and are targets for radiation damage, the involvement of these fats in all sorts of antirespiratory degenerative processes deserves more attention. Darkness, like irradiation, excess lactate, and unsaturated fats, has the diabetes-like effect of greatly reducing the ability of muscle to absorb sugar, while light stimulates respiration"
