JackyKey Takeaway:
- The best light color for sleep is warm white or yellow light. Warm white light has a similar color temperature to incandescent bulbs, while yellow light has a calming effect on the eyes and promotes relaxation. These colors of light don’t disrupt the production of melatonin, the sleep hormone, and help maintain a healthy sleep pattern.
- Avoid using blue light before bed to help maintain a healthy sleep wake cycle. Blue light disrupts the body’s biological clock, reduces melatonin production, and impairs sleep quality. To reduce blue light exposure, limit screen time at least an hour before bed, use blue-blocking glasses, and use warm-colored light bulbs in the bedroom.
- Creating the right sleep environment is key to improving sleep habits. This includes controlling the amount and color of light in the bedroom, blocking out external sources of light, and designing a relaxing sleep space. Considering the role of light in sleep can improve sleep hygiene and help promote better quality rest.
How Light Affects Sleep

Need better sleep? It’s time to get light-savvy!
The circadian rhythm impacts your sleep pattern. This can cause insomnia and other sleep issues. Melatonin is key for good sleep health. Too much blue light can mess with melatonin production. But, don’t worry! There are ways to use light therapy, color temperature, and bedroom lighting to help.
Circadian Rhythm
Our body’s natural sleep-wake cycle is regulated by a biological process called the daily rhythm. This internal clock, also known as the circadian system, ramps up in response to bright light and suppresses in darkness. Sleep patterns can be disrupted by various factors, including certain medications, caffeine, alcohol and exposure to blue light before bed.
The circadian rhythm governs more than just sleep; it influences hormone production, digestion, body temperature and other vital physiological functions. The body releases melatonin during dark hours to aid in restful sleep. Disruptions to this hormone production often result in insomnia or other sleep disorders.
To maintain optimal sleep patterns, it is important to regulate our circadian rhythms with appropriate lighting. Different colors of light during specific times of day contribute differently to these biological processes. For instance, red light has been shown to enhance melatonin production while not disrupting the circadian rhythm compared to blue light.
While not as effective as red light for promoting restful sleep, orange light may help you wind down before bed and encourage relaxation. Yellow light has also shown similar effects on calming the mind before bedtime, although yellow enhances wakefulness rather than inducing drowsiness.
Warm white lighting (2700-3000K) color temperatures mimic the warmth of natural indoor lighting after dark and have been linked to increasing melatonin levels and improving overall circulation & heart rate before bed.
By avoiding blue light from phones or computer screens two hours before bedtime, your brain will produce more melatonin that could lead to improved mental health along with a higher likelihood of good night’s rest. Be sure your bedroom is dimly lit leading up until bedtime for facilitating quality slumber.
Don’t suffer from insomnia or other sleep disorders-get the best light color for your nightly routine! Light exposure can either boost or bust your sleep health and quality, and melatonin production is the key player in this game.
Melatonin Production
Studies have suggested that light exposure has significant effects on sleep quality and overall sleep health. Specifically, the production of the hormone melatonin is heavily influenced by the presence or absence of light. Melatonin is a hormone produced in the pineal gland in response to darkness, which helps regulate the circadian rhythm. While levels of melatonin typically rise in the evening and fall during the day, exposure to artificial light at night can significantly suppress its production.
In addition to general light exposure, the type of light can also play a significant role. For example, blue light has been shown to be particularly effective at suppressing melatonin production, while warm colors like red and orange have less of an impact. Additionally, yellow and warm-white lights typically induce less strain for your eyes than blue-light heavy ones.
It’s important for individuals to take their light exposure into consideration when attempting to improve their sleep quality. By avoiding blue-light heavy screens before bed and utilizing warmer forms of lighting throughout your space will lead one towards better sleep patterns along with maintaining optimal health conditions.
Blue light may be great for light therapy and natural lighting, but it’s not the best for bedroom lighting and sleep.
Blue Light
The blue wavelength, found in natural light and many electronic devices, affects sleep by suppressing melatonin production. This can lead to difficulty falling asleep and disrupted circadian rhythms.
Light therapy suggests using light with a color temperature of less than 3000K for bedroom lighting. Yellow, warm white, and red-orange lights are better alternatives to blue light. These colors have a lower impact on the production of melatonin.
To avoid blue light exposure before bed, use night mode on electronic devices or download apps that reduce blue light emissions. Additionally, dimming lights an hour before bedtime and using lamps with warm-colored bulbs can promote healthy sleep patterns.
