How Much Sleep Do You Need?
Exploring your sleep needs and the different stages of sleep
Tired of tossing and turning at night? These simple sleep hygiene tips can help you fall asleep quickly, stay asleep longer, and be more energetic and productive during the day.
Sleeping well directly affects your mental and physical health. Fall short and it can take a serious toll on your daytime energy, productivity, emotional balance, and even your weight. Yet many of us regularly toss and turn at night, struggling to get the sleep we need.
Getting a good night’s sleep may seem like an impossible goal when you’re wide awake at 3 a.m., but you have much more control over the quality of your sleep than you probably realize. Just as the way you feel during your waking hours often hinges on how well you sleep at night, so the cure for sleep difficulties can often be found in your daily routine.
Unhealthy daytime habits and lifestyle choices can leave you tossing and turning at night and adversely affect your mood, brain and heart health, immune system, creativity, vitality, and weight. Whether you struggle to fall asleep when you get into bed or wake up in the night and find it difficult to go back to sleep, the solution often lies in establishing healthy sleep habits, known as “sleep hygiene”. By improving your sleep hygiene, you can fall asleep faster, stay asleep for longer, boost your overall health, and improve how you think and feel during the day.
Getting in sync with your body’s natural sleep-wake cycle, or circadian rhythm, is one of the most important strategies for sleeping better. If you keep a regular sleep-wake schedule, you’ll feel much more refreshed and energized than if you sleep the same number of hours at different times, even if you only alter your sleep schedule by an hour or two.
Try to go to sleep and get up at the same time every day. This helps set your body’s internal clock and optimize the quality of your sleep. Choose a bed time when you normally feel tired, so that you don’t toss and turn. If you’re getting enough sleep, you should wake up naturally without an alarm. If you need an alarm clock, you may need an earlier bedtime.
Avoid sleeping in—even on weekends. The more your weekend/weekday sleep schedules differ, the worse the jetlag-like symptoms you’ll experience. If you need to make up for a late night, opt for a daytime nap rather than sleeping in. This allows you to pay off your sleep debt without disturbing your natural sleep-wake rhythm.
Be smart about napping. While napping is a good way to make up for lost sleep, if you have trouble falling asleep or staying asleep at night, napping can make things worse. Limit naps to 15 to 20 minutes in the early afternoon.
Start the day with a healthy breakfast. Among lots of other health benefits, eating a balanced breakfast can help sync up your biological clock by letting your body know that it’s time to wake up and get going. Skipping breakfast on the other hand, can delay your blood sugar rhythms, lower your energy, and increase your stress, factors that may disrupt sleep.
Fight after-dinner drowsiness. If you get sleepy way before your bedtime, get off the couch and do something mildly stimulating, such as washing the dishes, calling a friend, or getting clothes ready for the next day. If you give in to the drowsiness, you may wake up later in the night and have trouble getting back to sleep.
Melatonin is a naturally occurring hormone controlled by light exposure that helps regulate your sleep-wake cycle. Your brain secretes more melatonin when it’s dark—making you sleepy—and less when it’s light—making you more alert. However, many aspects of modern life can alter your body’s production of melatonin, shift your circadian rhythm, and make it harder to sleep.
Here’s how to influence your exposure to light:
Expose yourself to bright sunlight in the morning. The closer to the time you get up, the better. Have your coffee outside, for example, or eat breakfast by a sunny window. The light on your face will help you wake up
Spend more time outside during daylight. Take your work breaks outside in sunlight, exercise outside, or walk your dog during the day instead of at night.
Let as much natural light into your home or workspace as possible. Keep curtains and blinds open during the day, and try to move your desk closer to the window.
If necessary, use a light therapy box. This simulates sunshine and can be especially useful during short winter days.
Avoid bright screens within 1-2 hours of your bedtime. The blue light emitted by your phone, tablet, computer, or TV is especially disruptive. You can minimize the impact by using devices with smaller screens, turning the brightness down, or using light-altering software such as f.lux.
Say no to late-night television. Not only does the light from a TV suppress melatonin, but many programs are stimulating rather than relaxing. Try listening to music or audio books instead.
Don’t read with backlit devices. Tablets that are backlit are more disruptive than e-readers that don’t have their own light source.
When it’s time to sleep, make sure the room is dark. Use heavy curtains or shades to block light from windows, or try a sleep mask. Also consider covering up electronics that emit light.
Keep the lights down if you get up during the night. If you need some light to move around safely, try installing a dim nightlight in the hall or bathroom or using a small flashlight. This will make it easier for you to fall back to sleep.
People who exercise regularly fall asleep faster at night, sleep better, and feel less sleepy during the day. Regular exercise also improves the symptoms of insomnia and sleep apnea and increases the amount of time you spend in the deep, restorative stages of sleep.

Exercise speeds up your metabolism, elevates body temperature, and stimulates hormones such as cortisol. This isn’t a problem if you’re exercising in the morning or afternoon, but too close to bed and it can interfere with sleep.
Try to finish moderate to vigorous workouts at least three hours before bedtime. If you’re still experiencing sleep difficulties, move your workouts even earlier. Relaxing, low-impact exercises such as yoga or gentle stretching in the evening can help promote sleep.
Your daytime eating habits play a role in how well you sleep, especially in the hours before bedtime.
Focus on a heart-healthy diet. It’s your overall eating patterns rather than specific foods that can make the biggest difference to your quality of sleep, as well as your overall health. Eating a Mediterranean-type diet rich in vegetables, fruit, and healthy fats—and limited amounts of red meat—may help you to fall asleep faster and stay asleep for longer.
Cut back on sugary foods and refined carbs. Eating lots of sugar and refined carbs such as white bread, white rice, and pasta during the day can trigger wakefulness at night and pull you out of the deep, restorative stages of sleep.
Limit caffeine and nicotine. You might be surprised to know that caffeine can cause sleep problems up to ten to 12 hours after drinking it! Similarly, smoking is another stimulant that can disrupt your sleep, especially if you smoke close to bedtime.
Avoid big meals at night. Try to make dinnertime earlier in the evening, and avoid heavy, rich foods within two hours of bed. Spicy or acidic foods can cause stomach trouble and heartburn.
Avoid alcohol before bed. While a nightcap may help you relax, it interferes with your sleep cycle once you’re out.
Avoid drinking too many liquids in the evening. Drinking lots of fluids may result in frequent bathroom trips throughout the night.
For some people, a light snack before bed can help promote sleep. For others, eating before bed leads to indigestion and makes sleeping more difficult. If you need a bedtime snack, try:
A peaceful bedtime routine sends a powerful signal to your brain that it’s time to wind down and let go of the day’s stresses. Sometimes even small changes to your environment can make a big difference to how fast you fall asleep and the quality of your sleep.
Keep noise down. If you can’t avoid or eliminate noise from neighbors, traffic, or other people in your household, try masking it with a fan or sound machine. Earplugs may also help.
Keep your room cool. Most people sleep best in a slightly cool room (around 65° F or 18° C) with adequate ventilation. A bedroom that is too hot or too cold can interfere with quality sleep.
Make sure your bed is comfortable. Your bed covers should leave you enough room to stretch and turn comfortably without becoming tangled. If you often wake up with a sore back or an aching neck, you may need to experiment with different levels of mattress firmness, foam toppers, and pillows that provide more or less support. Using an adjustable base could help to improve your sleep position.
Reserve your bed for sleeping and sex. By not working, watching TV, or using your phone, tablet, or computer in bed, your brain will associate the bedroom with just sleep and sex, which makes it easier to wind down at night.
Do you often find yourself unable to get to sleep or regularly waking up night after night? Residual stress, worry, and anger from your day can make it very difficult to sleep well. Taking steps to manage your overall stress levels and learning how to curb the worry habit can make it easier to unwind at night. You can also try developing a relaxing bedtime ritual to help you prepare your mind for sleep, such as practicing a relaxation technique, taking a warm bath, or dimming the lights and listening to soft music or an audiobook.
Problems clearing your head at night can also stem from your daytime habits. The more overstimulated your brain becomes during the day, the harder it can be to slow down and unwind at night. Maybe, like many of us, you’re constantly interrupting tasks during the day to check your phone, email, or social media. Then when it comes to getting to sleep at night, your brain is so accustomed to seeking fresh stimulation, it becomes difficult to unwind.
Help yourself by setting aside specific times during the day for checking your phone and social media and, as much as possible, try to focus on one task at a time. You’ll be better able to calm your mind at bedtime.
Breathing from your belly rather than your chest can activate the relaxation response and lower your heart rate, blood pressure, and stress levels to help you drift off to sleep.

It’s normal to wake briefly during the night but if you’re having trouble falling back asleep, these tips may help:
Stay out of your head. Hard as it may be, try not to stress over your inability to fall asleep again, because that stress only encourages your body to stay awake. To stay out of your head, focus on the feelings in your body or practice breathing exercises. Take a breath in, then breathe out slowly while saying or thinking the word, “Ahhh.” Take another breath and repeat.
Make relaxation your goal, not sleep. If you find it hard to fall back asleep, try a relaxation technique such as visualization, progressive muscle relaxation, or meditation, which can be done without even getting out of bed. Even though it’s not a replacement for sleep, relaxation can still help rejuvenate your body.

Do a quiet, non-stimulating activity. If you’ve been awake for more than 15 minutes, get out of bed and do a quiet, non-stimulating activity, such as reading a book. Keep the lights dim and avoid screens so as not to cue your body that it’s time to wake up.
Postpone worrying and brainstorming. If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when it will be easier to resolve. Similarly, if a great idea is keeping you awake, make a note of it on paper and fall back to sleep knowing you’ll be much more productive after a good night’s rest.
