Chronotype refers to the preferred timing throughout the day-night period for when we sleep, as well as for activities and performance during wakefulness. It is most popularly defined into two categories: Morning types (larks) and Evening types (owls).
Bright lights in the morning will not only generate an alerting affect in the brain, but will also help to strengthen and shift our circadian rhythm making for a better sleep-wake cycle.
It is commonly mentioned to avoid bright lights and screen time before bed in order to achieve better sleep. This is because the eyes have a direct connection to the structure of the brain that regulates our circadian rhythm, our internal biological clock.
