The science
Calmer evenings start with the light you let in.
Your body keeps time by light. Screens and indoor lighting after sunset tell it the day isn’t over, so melatonin, the hormone that signals night, is held back. Blue light has also been linked to a stimulatory effect on cortisol, the hormone that keeps you alert and under pressure. It is one reason an evening can feel wired instead of calm.
