Back to School in a Pandemic: Tips to Foster Mental Health In this way, cortisol plays a critical role in sleep-wake cycles: stimulating wakefulness in the morning, continuing to support alertness throughout the day while gradually dropping to allow the body’s own internal sleep drive and other hormones—including adenosine and melatonin—to rise, and help bring about sleep.
