Light with higher kelvin (K) is best used to help you feel more awake and focused, while light with lower kelvin is better for relaxing. You're probably familiar with this concept from your smartphone, with "night mode" now a popular feature. This feature has become so widespread because blue light suppresses melatonin, and when we expose ourselves to blue light at night, our sleeping pattern can get disturbed.
Want to go to sleep more peacefully? Use warm, golden light around bedtime. And if you have to turn the lights on in the middle of the night, keep them warm and red-toned — this excludes that melatonin-suppressing blue light.
Want to wake up in a better mood? Create a Wake up automation that rouses you by gently brightening the lights, which has been shown to improve mood.
Want to be more alert? Automate your lights to switch to bright, cool light. Good morning!
Because light color can have such an impact on our health, it's a good idea to incorporate color lights in your bedroom. This way, you can set any mood you want!
