How much sleep a person needs varies from person to person. The number of hours you sleep is not as important as how you feel when you wake up. If you to do not feel refreshed, you probably need more sleep. Feeling tired during the daytime is another sign you are not getting enough sleep. The average total nightly sleep time is 7½ to 8 hours. Healthy adults can require anywhere from 4 to 10 hours of sleep. Many times, simple home treatment can help you get the sleep you need.

If your sleep problem does not require a visit to your health professional, establish a routine to promote good sleep habits:

• Set a bedtime and time to get up, and stick to them, even on weekends. This will help your body get used to a regular sleep time.
• Exercise during the day. Avoid strenuous exercise within 2 hours of bedtime.
• Wind down toward the end of the day. Don't take on problem-solving conversations or challenging activities in the evening.
• Take a warm bath before bed.
• Keep your bedroom dark, cool, and quiet.
• Remove distractions, such as a clock, telephone, or radio, from your bedroom.
• Use a humidifier or "white noise" machine to block out background noise in your bedroom throughout the night.
• Try using a sleep mask and earplugs at night.
• If you take medicine that may be stimulating, such as antihistamines, decongestants, or asthma medicines, take them as long before bedtime as possible.
• Reserve the bedroom for sleeping and sexual activities so that you come to associate it with sleep. Go to another room to read, watch television, or eat.
• After getting into bed, make a conscious effort to let your muscles relax. Imagine yourself in a peaceful, pleasant scene. For more information, see the topic Stress Management.

When you cannot get to sleep, try the following:

• If you are still awake after 15 or 20 minutes, get up and read in dim light or do a boring task until you feel drowsy. Don't lie in bed and think about how much sleep you're missing or watch TV.

Avoid activities that might keep you from a good night's sleep:

• Do not take naps during the day, especially in the evening.
• Do not drink or eat caffeine after 3:00 p.m. This includes coffee, tea, cola drinks, and chocolate.
• Do not smoke or use other tobacco products. Nicotine can disrupt sleep and reduce total sleep time. Smokers report more daytime sleepiness and minor accidents than do nonsmokers, especially in younger age groups. For more information, see the topic Quitting Tobacco Use.
• Avoid drinking alcohol. It may make you sleepy but also will probably wake you up after a short time.
