Red light therapy has moved from elite sports clubs into everyday recovery routines. It is also surrounded by bold claims. This is a plain account of what it is, what the evidence suggests and what a session at Floatwell involves.
What red light therapy is
A red light bed bathes the body in red and near-infrared light from panels of LEDs. It is not a sunbed: there is no ultraviolet light, so it does not tan or burn. You lie on the bed, the light runs for a set time, and you feel little more than gentle warmth.

How it is thought to work
Red and near-infrared light is absorbed by cells, particularly by the mitochondria that produce their energy. The leading theory, often called photobiomodulation, is that this light helps cells produce energy more efficiently and calms local inflammation.
What the research shows
Studies on red and near-infrared light for exercise recovery suggest it may reduce muscle soreness and support performance in some settings, and it is widely used in sport for that reason. Results vary between studies, devices and doses, and the research is still developing. We describe red light as a promising, low-risk part of a recovery routine, not a cure for anything.
What a session at Floatwell involves
Our red light bed is in a private room. You lie down, the session runs, and you are free to go — no shower or recovery time needed. A single session is £35. It is also part of several of our recovery packages, alongside the infrared sauna, compression suit and sports massage.
Who it suits
- Runners, lifters and team-sport players looking for an easy addition to recovery days.
- People combining it with a sauna or massage as part of a regular routine.
- Anyone curious to try it before committing to a course.
Who should check first
If you are pregnant, have a condition that makes you sensitive to light, take medication that increases light sensitivity, or have a history of skin cancer, check with your GP before booking. Keep your eyes closed while the light is on.
Combining it with other treatments
Red light pairs naturally with heat and rest. A common order is infrared sauna first, then red light, then a float or massage. Our Recovery Taster is the simplest way to try the combination.
