Not a trend. A therapy.
PHOTOBIOMODULATION EXPLAINED
Red light therapy has been studied for over four decades by NASA, Harvard Medical School, and leading research institutions worldwide. The NightSwitch uses clinically validated wavelengths — 660nm and 850nm — to support your body's natural sleep cycle.

Known side effects
How red light prepares you for sleep
Light Absorption
Red and near-infrared photons are absorbed by cytochrome-c oxidase in your mitochondria.
Melatonin Support
Stimulates your pineal gland to produce melatonin naturally, signalling to your body it's time to sleep.
Circadian Reset
Consistent nightly use recalibrates your body clock for deeper, more restorative sleep cycles.
Myth vs. Fact
Unlike blue light, red and near-infrared wavelengths do not suppress melatonin production. Studies show red light in the evening can actually increase melatonin levels and improve sleep quality.
Red light therapy uses specific wavelengths (660nm and 850nm) with zero UV radiation. It cannot burn or damage skin — tanning beds do.
Wavelength accuracy matters more than brightness. A device outside 600–850nm produces little benefit regardless of intensity.
Red light therapy works cumulatively. Most studies show measurable results after 4–8 weeks of consistent use.
Red light therapy is backed by over 5,000 peer-reviewed studies spanning four decades, including research from NASA and Harvard Medical School.
What leading researchers say
The applications of PBM therapy are extremely diverse in modern medicine, so that it has gained considerable credibility among available therapeutic strategies.
