How does the brain know when we should sleep? Well, our brain helps regulate our sleeping schedule through our circadian rhythm. Our circadian rhythm can be defined as the brain’s system of determining when our body needs to sleep or stay awake based on environmental factors, like whether it is sunny or dark outside. According to the National Sleep Foundation, different ages require varied amounts of sleep to stay healthy. Children ages 6-13 require 9-11 hours of sleep, teens ages 14-17 need 8-10 hours of sleep, and adults ages 18-64 require 7-9 hours of sleep.
