Can Red Light Therapy Improve Your Sleep?

Light and Circadian Rhythm

Your body's sleep-wake cycle (circadian rhythm) is regulated by light. Blue light (from screens and overhead lighting) suppresses melatonin production and signals wakefulness. Red and near-infrared light, by contrast, do not suppress melatonin and may actually support the transition to sleep by reducing cortisol and promoting relaxation.

What the Research Shows

A 2012 study published in the Journal of Athletic Training found that female basketball players who received red light therapy showed significant improvements in sleep quality, melatonin levels, and athletic performance compared to controls. Multiple other studies have shown improvements in sleep duration and quality with consistent red light use.

• May increase melatonin production
• Reduces cortisol (stress hormone) levels
• Supports circadian rhythm regulation
• Improves sleep quality scores in clinical studies
• Non-habit forming — no medication required

Practical Application at LightLab

Evening sessions at LightLab Wellness in Clive can be particularly beneficial for sleep. The warm, non-stimulating wavelengths of the Dahlia bed create a deeply relaxing experience that many members describe as 'the best 20 minutes of their day.' We're open until 7pm Monday through Thursday to accommodate evening sessions.
