Daylight helps us regulate our circadian rhythms - the daily cycle of waking and sleeping. These natural rhythms are affected by signals from our environment, the most important of which is daylight. For optimal daytime productivity we need to get good quality sleep. Exposure to daylight turns the genes that control our internal clocks on and off.
