While daily physical activity is great, you'll sleep much better if you finish your workout at least three hours before your bedtime to allow the stimulating effects of exercise to dissipate.
Nix late-night meals, which may interfere with your ability to sleep soundly, and give your body a rest from digestion. Try to finish supper at least three hours before you turn in for the night, and keep any bedtime snacks on the light side.
"Alcohol first induces sleep because it's a sedating compound," says Dr. Charles Samuels of Calgary's Centre for Sleep and Human Performance, "but then it disrupts sleep because the alcohol leaves the system very quickly." He adds that the depressant also suppresses REM, or dream, sleep, which the body needs to repair itself. If you have a drink with dinner, however, it will likely clear your system by bedtime, so it shouldn't affect your sleep cycle.
Staring at your computer, tablet or smartphone until lights-out can curtail your ability to doze off (interestingly, watching TV is fine, as long as it's not done in bed). The light from these devices suppresses the release of sleep-inducing melatonin from our brains, and the stimulation from games, emails and social media keeps our brains active. For best sleep, turn off devices three hours before bedtime and keep all screens out of the bedroom.
