Red light therapy — sometimes called photobiomodulation — uses specific wavelengths of visible red and near-infrared light to support the body in a gentle, non-invasive way. It has moved from professional clinics and recovery rooms into calm, everyday home rituals.
The wavelengths that matter
Most wellness devices focus on two ranges: visible red light around 660 nm and deeper near-infrared around 850 nm. Red light works closer to the surface, while near-infrared reaches further into tissue.
Why people use it
- As part of a calming skincare ritual
- To support comfortable muscle and joint recovery
- To create a quiet, screen-free pause in the day
Red light therapy is designed to be used consistently and gently. Most people build a short daily habit of just a few minutes.
