Daylight & blue light
Getting the right amount of daylight is a huge part of keeping the circadian rhythm on point, which is the internal regulator of sleep and wakefulness. “Sunlight is probably the most important factor that gives the signal to our brain that it’s time to be awake, and diminishing amounts of the light signal that it is now the time for our body to get ready for sleep.” as Mairav Cohen-Zion, the chief science officer of dayzz, explained.
Cohen-Zion also added that it’s highly recommended to get a minimum of 20 to 30 minutes of sunlight in the morning and try to avoid blue light 2 hours before bedtime. It will make your sleep-wake cycle more robust, and help you feel awake or sleepy just when you’re supposed to.
