Red Light Therapy for Sleep: A Simple Way to Sleep Better
Do you have trouble falling asleep at night? You’re not alone. Many people struggle with sleep. One way to help is with something called red light therapy. It’s a safe, natural way to sleep better. This blog will show how red light therapy for sleep works and why it helps your body rest.
What Is Red Light Therapy?
Red light therapy is a type of light treatment. It uses red-tinted lighting to help your body feel calm and relaxed. This light is not bright or harsh like some white light or blue lights. Instead, it feels warm and gentle on your eyes.
People use red light therapy instruments or light therapy boxes at home or in wellness centers. Some healthcare providers also use it. This therapy is a type of noninvasive therapy, meaning it doesn’t hurt and doesn’t go inside your body.
How Does Red Light Therapy Help Sleep?
When it gets dark, your body makes something called melatonin. Melatonin helps you get sleepy and stay asleep. But when there is too much artificial light, especially blue light from phones or TVs, your body slows down melatonin production.
That’s where red light therapy helps. Red light doesn’t stop melatonin like other lights do. Instead, it supports the natural production and release of melatonin. This helps your body get ready for bed.
Some studies show that red light can:
- Boost melatonin levels
- Improve sleep efficiency
- Help with chronic insomnia
- Reset your biological clock or internal clock
What Is the Circadian Rhythm?
You may have heard the word circadian rhythm. This is your body’s natural clock. It helps you know when it’s time to sleep or wake up.
The circadian rhythm works best when you sleep and wake at the same times every day. But light at night can confuse your clock. Red light therapy helps you keep a healthy rhythm so you can get better rest.
People with circadian rhythm sleep disorder or psychophysiologic insomnia may feel sleepy at the wrong times or wake up too early. Red light can help get their schedule back on track.
Who Can Benefit from Red Light Therapy?
Red light therapy for sleep can help many people, like:
- Kids and adults with trouble falling asleep
- Female athletes who train late at night
- Female basketball players with high stress levels
- People with sleep disorders, including early-morning awakening insomnia
- Adults with insomnia
In one study, red-light treatment participants had better sleep quality after just a short postintervention period. The Pittsburgh Sleep Quality Index showed an improvement in serum melatonin and improved sleep variables.
What Does Science Say About Red Light Therapy?
Doctors and scientists have studied how light wavelength affects sleep. Red light has longer wavelengths. These wavelengths are calming and help you feel relaxed.
One study showed a correlation between sleep quality and melatonin levels in athletes. Another found red-light treatment helped increase Gamma – Melatonin levels and supported alleviation of sleep maintenance problems.
Studies also tracked performance among basketball players and exercise on sleep quality, showing that better sleep leads to better energy level and aerobic performance.
Sources like the Trusted Source National Library of Medicine show red light is safe and effective when used right.
How to Use Red Light Therapy for Sleep
You don’t need a doctor’s visit to try red light therapy. Many light therapy products are easy to use at home. Here’s how:
- Use a red-light therapy device or diode therapy tool.
- Place it near your bed or in your room.
- Use it during your nighttime routine or before bed.
- Try a 12-minute test period and see how it feels.
- Use the light each night for a period of time to see results.
Some people like red-tinted light bulbs in their bedroom. Others prefer a red light source they can turn on and off.
Always think about your personal preference, and make sure you give informed consent if you’re trying therapy with a professional.
Red Light Therapy vs. Other Light Types
| Light Type | Good for Sleep? | Notes |
|---|---|---|
| Red Light | ✅ Yes | Boosts melatonin, supports calm |
| Blue Light | ❌ No | Stops melatonin, wakes you up |
| White Light | ❌ No | Bright and may cause melatonin suppression |
| Night Mode | ✅ Maybe | Helps a little but not as much as red light |
Avoiding bright light at night can make a big difference. Red light helps keep your serum melatonin levels high so you fall asleep faster.
Real Results from Red Light Therapy
In a study on human participants, people using red light before bed had:
- Better scores on the Pittsburgh Sleep tests
- Fewer correlates of sleep complaints
- More positive emotion items and fewer negative emotion items
- Decreases in sleep quality reversed over time
One group was given red-light treatment, while another group was given a placebo. The red-light treatment group had better rest and felt more refreshed in the morning.
Athletes also had improvements in endurance performance and less exercise-induced skeletal muscle fatigue, including knee extensor muscle fatigue.
