Said Hasyim's Quote

"Regular sleep regulates your stress level throughout the day. Your cortisol level is higher as you wake up to prepare you for work and handling any stressful events, and lower at night to prepare you for sleep."
Peak Human Clock

Good sleep hygiene can have a huge affect on your stress levels throughout the day.
