Have a good night sleep!

Try these ideas to find the sleep formula that works best for you.

1. Set a sleep schedule—and stick with it



If you do only one thing to improve your sleep, this is it, says Dr. Breus: Go to bed at the same time every night and get up at the same time every morning—even on weekends. A regular sleep routine keeps your biological clock steady so you rest better. Exposure to a regular pattern of light and dark helps, so stay in sync by opening the blinds or going outside right after you wake up (bonus: morning light has been shown to keep you slim)



2. Keep a sleep diary

To help you understand how your habits affect your rest, track your sleep every day for at least 2 weeks. Write down not only what's obviously sleep related—what time you go to bed, how long it takes you to fall asleep, how many times you wake up during the night, how you feel in the morning—but also factors like what you ate close to bedtime and what exercise you got. Comparing your daily activities with your nightly sleep patterns can show you where you need to make changes.

  

3. Stop smoking

Reason number 1,001: Nicotine is a stimulant, so it prevents you from falling asleep. Plus, many smokers experience withdrawal pangs at night. Smokers are 4 times more likely not to feel as well rested after a night's sleep than nonsmokers, studies show, and smoking exacerbates sleep apnea and other breathing disorders, which can also stop you from getting a good night's rest. Don't worry that quitting will keep you up nights too: That effect passes in about 3 nights, says Lisa Shives, MD, sleep expert and founder of Northshore Sleep Medicine.

4. Review your medications

Beta-blockers (prescribed for high blood pressure) may cause insomnia; so can SSRIs (a class of antidepressants that includes Prozac and Zoloft). And that's just the beginning. Write down every drug and supplement you take, and have your doctor evaluate how they may be affecting your sleep.

5. Exercise, but not within 4 hours of bedtime



Working out—especially cardio—improves the length and quality of your sleep, says Dr. Shives. That said, 30 minutes of vigorous aerobic exercise keeps your body temperature elevated for about 4 hours, inhibiting sleep. When your body begins to cool down, however, it signals your brain to release sleep-inducing melatonin, so then you'll get drowsy.

6. Cut caffeine after 2 pm



That means coffee, tea, and cola. Caffeine is a stimulant that stays in your system for about 8 hours, so if you have a cappuccino after dinner, come bedtime, it'll either prevent your brain from entering deep sleep or stop you from falling asleep altogether.

7. Write down your woes



"The number one sleep complaint I hear? 'I can't turn off my mind,' " says Dr. Breus. To quiet that wakeful worrying, every night jot down your top concerns—say, I have to call my insurer to dispute that denied claim, which will take forever, and how can I spend all that time on the phone when work is so busy? Then write down the steps you can take to solve the problem—I'm going to look up the numbers before breakfast, refuse to stay on hold for more than three minutes, and send e-mails tomorrow night if I can't get through—or even I can't do anything about this tonight, so I'll worry about it tomorrow. Once your concerns are converted into some kind of action plan, you'll rest easier.

  

8. Take time to wind down

"Sleep is not an on-off switch," says Dr. Breus. "It's more like slowly easing your foot off the gas." Give your body time to transition from your active day to bedtime drowsiness by setting a timer for an hour before bed and divvying up the time as follows:
First 20 minutes: Prep for tomorrow (pack your bag, set out your clothes).
Next 20: Take care of personal hygiene (brush your teeth, moisturize your face).
Last 20: Relax in bed, reading with a small, low-wattage book light or practicing deep breathing.
