Answers: How can I get better sleep?

• sleep hygiene
• caffeine and sleep
• screen time before bed
• circadian rhythm

What it concludes

• Consuming caffeine 3 hours before habitual bedtime induces a 40-minute phase delay of the circadian melatonin rhythm in humans.
• Getting 8 hours of sleep requires more time in bed than 8 hours to account for time to fall asleep and nighttime tossing and turning.
• Using screens before bed delays your body's internal clock, suppresses the release of sleep-inducing melatonin, and makes it more difficult to fall asleep.
