Struggling to Sleep?
If you’re reading this late at night, you might be one of the millions dealing with sleep disorders. Sleep disorders prevent restful sleep and, when chronic, have significant impacts on quality of life. Occasional sleepless nights aren’t a concern, but persistent sleep deprivation can have severe long-term consequences. (Source)
Why Is Sleep So Important?
Over the past few years, research has highlighted sleep as a critical factor for overall health. Chronic sleep deprivation has been closely linked to hypertension, heart attacks, strokes, obesity, diabetes, depression, anxiety, impaired brain function, memory loss, weakened immunity, reduced fertility, and psychiatric disorders.

Poor sleep is also tied to an increase in workplace injuries and traffic accidents, negatively affecting economic productivity. Despite these consequences, 35.5% of U.S. adults sleep less than the recommended 7–9 hours per night. Teens, who need even more sleep for cognitive development, fare worse, with 75% sleeping less than 8 hours. (Source)
Why Aren’t We Sleeping Well?
Common factors include:
- Caffeine: Consuming caffeine even 6 hours before bedtime can reduce total sleep by an hour. (Source)
- Exercise: Lack of physical activity can reduce deep sleep, which is critical for recovery and mood regulation. (Source)
- Stress: Persistent stress increases cortisol and adrenaline, delaying relaxation and disrupting sleep. (Source)
- Poor sleep habits: Irregular sleep schedules, screen usage in bed, and environmental factors like noise and light can severely impact sleep quality.
How Light Affects Sleep
Your circadian rhythm, a 24-hour internal clock, determines your sleep-wake cycle. Controlled by the pineal gland, it regulates melatonin production in response to light exposure. Bright and blue light suppress melatonin and promote wakefulness, while dim, red light encourages melatonin production and relaxation. (Source)
Modern artificial light, especially from screens, disrupts this natural process. Exposure to blue light at night confuses the pineal gland, suppressing melatonin, raising cortisol, and disrupting sleep cycles. (Source)
How Red Light Therapy Can Improve Sleep
Red light therapy (RLT) offers a natural, non-invasive way to improve sleep by regulating your circadian rhythm. Unlike blue light, red light soothes the body, encouraging relaxation and melatonin production.
Key Benefits of RLT for Sleep
- Boosts Melatonin: A study on female basketball players showed a significant increase in sleep quality and melatonin levels after two weeks of nightly red light therapy. (Source)
- Reduces Sleep Inertia: Red light exposure post-nap improved cognitive performance and reduced grogginess in shift workers. (Source)
- Enhances Workouts: RLT boosts muscle recovery, allowing better workouts and, consequently, better sleep. (Source)
- Eases Pain and Inflammation: Chronic pain, a common sleep disruptor, can be alleviated with RLT, reducing discomfort and improving sleep. (Source)
- Establishes a Bedtime Routine: Using red light at night can signal to your body that it’s time to unwind, creating a consistent bedtime habit.
Safe for Daily Use
Unlike sleep aids, which often come with side effects like brain fog or dependency, red light therapy is safe for daily use, with rare and mild side effects.
Light-Related Tips for Better Sleep
At Night:
- Use blackout curtains or a sleep mask.
- Replace nightlights with dim red or orange bulbs.
- Avoid screens 30–60 minutes before bed.
During the Day:
- Open blinds in the morning to let in natural light.
- Get outdoor sunlight exposure to improve alertness and mood.
