Best colored light for sleeping

Sleep is essential to a healthy lifestyle. It helps maintain physical and mental well-being. A good night’s sleep is not only related to the amount of sleep, but also to the quality of sleep. One of the factors affecting sleep quality is the color of light we sleep with. This article explains what is the best colored light for sleeping and how it affects our sleep.[1]

The best light color for sleeping is red

When it comes to the best color of light for sleeping, red is the winner. Red light has the least impact on circadian rhythm and melatonin production. This means it won’t disrupt your sleep cycle or affect your sleep quality. In addition, red light has a calming effect on the body and mind, which can help you fall asleep faster and improve sleep quality.

The circadian rhythm

The circadian rhythm is a natural biological process that regulates the human sleep-wake cycle. It’s essentially an internal 24-hour clock that responds to environmental cues like light and darkness to determine when we feel awake or asleep. When it’s dark, the body produces melatonin, a hormone that promotes sleep. When it’s light, melatonin production decreases and the body feels awake and alert.

Different colors of light and their effect on sleep

• Blue light and sleep
• Red light and sleep
• Green light and sleep
• Yellow light and sleep

Blue light and sleep

Blue light is known to disrupt circadian rhythms and melatonin production. It is commonly emitted by electronic devices such as smartphones, tablets, and computers. Exposure to blue light before bed can suppress melatonin production, making it harder to fall asleep and stay asleep. It is best to avoid blue light before bed or use a blue light filter on electronic devices.

Red light and sleep

Red light has the least impact on circadian rhythm and melatonin production. It’s a calming color that promotes relaxation and can help you fall asleep faster. Additionally, red light has been shown to improve sleep quality, particularly in those with insomnia. You can use a red lightbulb or a filter to create a sleep-friendly environment.

Green light and sleep

Studies on the effects of green light on circadian rhythms and melatonin production are mixed. While some studies have shown that green light can help reset circadian rhythms and improve sleep quality, others have found no significant effects on melatonin production or sleep architecture.

Yellow light and sleep

Yellow light can have both positive and negative effects on sleep, depending on the context and timing of exposure.

On the one hand, yellow light has a lower color temperature than blue light emitted by electronic devices and has been shown to suppress the production of melatonin, a hormone that helps regulate sleep-wake cycles. Yellow light, on the other hand, is less disruptive to melatonin production and less likely to disrupt sleep.

In fact, some studies suggest that exposure to warm-colored light, including yellow light, in the evening hours can actually improve sleep quality and quantity by promoting relaxation and reducing alertness that may be keeping us awake. For this reason, many sleep experts recommend dimming the lights and using warmer light sources in the hours before bed.

However, it’s worth noting that exposure to yellow light or any other light source too close to bedtime can still interfere with sleep by delaying the onset of melatonin production and disrupting the body’s natural circadian rhythm. For this reason, it’s generally a good idea to limit exposure to bright lights and electronic devices in the hour or two before bed, regardless of the color temperature of the light source.

How to choose the best colored light for sleep

When choosing the best colored light for sleep, consider your sleeping environment, lighting fixtures, light filters, and screen time. Create a sleep-friendly environment by minimizing exposure to blue light, using the right lighting fixtures, and limiting screen time before bed.

Other factors affecting sleep quality

Temperature, noise and comfortable beds are other factors that affect sleep quality. It is important to create a comfortable sleeping environment that promotes relaxation and restful sleep.

In summary, the best light color for sleeping is red. Red light has the least impact on circadian rhythm and melatonin production, which helps to relax and improve sleep quality. However, it’s important to consider other factors that affect sleep quality, such as temperature, noise, and comfortable beds.

To create a sleep-friendly environment, consider using a red light lamp or filter, using the right lighting fixtures, and limiting screen time before bed. Through these adjustments, you can improve the quality of your sleep and wake up feeling refreshed and rejuvenated.
