1. Stick to a sleep schedule
Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces your body's sleep-wake cycle and helps promote better sleep at night. There's a caveat, though. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired. If you agonize over falling asleep, you might find it even tougher to nod off.
2. Pay attention to what you eat and drink
Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet.
Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine take hours to wear off and can wreak havoc on quality sleep. And even though alcohol might make you feel sleepy at first, it can disrupt sleep later in the night.
3. Create a bedtime ritual
Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to soothing music — preferably with the lights dimmed. Relaxing activities can promote better sleep by easing the transition between wakefulness and drowsiness.
Be wary of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime interferes with sleep.
4. Get comfortable
Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.
Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you share your bed, make sure there's enough room for two. If you have children or pets, try to set limits on how often they sleep with you — or insist on separate sleeping quarters.
