What it concludes

• Adults should sleep between 7 and 9 hours per night on a regular basis to promote optimal health and avoid adverse health outcomes.
• Maintaining a consistent sleep schedule and waking up at the same time helps synchronize internal chemistry and adenosine levels.
• Getting morning sunlight exposure within a few hours of waking helps trigger the release of cortisol and epinephrine for alertness and sets a 12 to 14 hour timer for melatonin release.
• Morning and light exercise helps build an anticipatory circuit that promotes morning energy and evening sleepiness.
• Stopping caffeine consumption 8 to 10 hours before bedtime prevents interference with adenosine receptors and improves sleep quality.
• Catching evening sunlight helps signal the circadian clock that sleep is approaching and promotes melatonin production later in the evening.
