Infrared light exposure, which is similar but not the same as red light therapy, should be limited to no more than 20 minutes in some instances.

These particles possess the unique property of absorbing near-infrared light, generally between 800 and 1,600 nanometres, and re-emitting this light as visible light at 400–700 nanometres.

Berly McCoy and Regina Barber of Short Wave talk about a hawk's clever hunting strategy, contacts that allow wearers to see infrared light, and how immunity varies during the day.

Researchers have finally figured out how mosquitoes see humans in the dark: They detect infrared light the body generates via heat.
