may still be shining overhead, there’s a chill in the wind which confirms the seasons are changing.
“Many of us are familiar with the stress-related hormone, cortisol, and how it keeps us awake and alert during the day. Melatonin, secreted by the pineal gland in the brain, calms our brain and allows us to fall and stay asleep.” In this way, when we wake up and it’s still dark outside, our bodies are still producing melatonin, which is why we continue to feel sleepy and groggy once our eyes are open. It’s for this reason– the bright, natural light triggers the release of cortisol, which helps you to feel more alert and dampens any feelings of grogginess.
