The best color light for sleeping is red.
Red light has the longest wavelength of visible light, which means it has the least amount of energy. This makes it less likely to disrupt your body's natural sleep-wake cycle, also known as your circadian rhythm.
Here's why red light is better for sleep:
- Minimizes melatonin suppression: Blue light, found in many electronic devices, suppresses the production of melatonin, a hormone that regulates sleep. Red light has a minimal effect on melatonin production, allowing your body to prepare for sleep naturally.
- Promotes relaxation: Red light can have a calming effect on the nervous system, making it easier to fall asleep.
- Reduces eye strain: Red light is less harsh on your eyes than blue light, making it more comfortable to use in the evening.
While red light is generally considered the best for sleep, you can also use other warm-toned colors like orange and yellow.
To maximize the benefits of red light for sleep, consider using a red light bulb in your bedroom or using a red light therapy lamp for 20-30 minutes before bedtime.
