Light therapy uses specific wavelengths—especially red and infrared—with some proven benefits from sunlight but mixed and frequency-dependent evidence for many commercial devices.

Wake is a tactile, science-backed sleep light that uses sunrise/sunset lighting and soundscapes to improve sleep, promote melatonin release, and enable gentler wake-ups.

Shorter fall days disrupt circadian rhythms, increase melatonin, lower vitamin D, and cause fatigue and mood changes mitigated by light therapy and vitamin D.
