Sleep helps you perform better during games or competitions, recover faster from training sessions, and according to a Clinical Journal of Sports Medicine study, can even help prevent injuries. But sleep isn't just good for your body, it helps the mind too, according to a 2003 study by the University of Michigan. The following guidelines will help you fall asleep and stay asleep.
Rule #2 Make sure your room is dark, quiet and cool.
Rule #4 Turn your alarm clock so it does not face your bed. Time pressure may contribute to poor sleep. In other words, don't watch your clock all night.
Rule #5 For at least an hour before bedtime, avoid activities such as watching a movie or reading a book that is depressing or has intense material, playing competitive games or listening to intense music.
Rule #6 Avoid computer use before sleep. A study showed that Internet use between 7:00 p.m. and midnight increases the risk of poor sleep among young adults.
Rule #7 Turn off the radio and television before you go to sleep since this may disrupt your sleep.
Rule #8 If you are having difficulty sleeping, engage in relaxing activities 20 to 30 minutes before sleep. Try gentle yoga, diaphragmatic breathing and progressive relaxation techniques or meditation.
Rule #9 Get enough regular exercise in the afternoon or early evening, but avoid it close to bedtime. The key may be the intensity. Avoid strenuous exercise within two to six hours of your bedtime. An easy walk, stretching and gentle yoga or tai chi may be fine for most individuals. Intense exercise close to bedtime acts as a stimulant and may prevent you from getting a good night's sleep. One study found that vigorous late-night exercise (on a stationary bicycle) did not disturb sleep in young and fit individuals without sleep disorders; however, sleep researchers typically recommend most people should avoid intense physical activity close to bedtime.
Rule #10 Increase your exposure to outdoor bright light during the day (especially in the morning upon awakening), and avoid bright light exposure during the night before sleep (including laptops, computers, smart phones and other artificial bright lights). In general, early bright light sun exposure is helpful in synchronizing your body clock and helping to awaken you in the morning. The best source of bright light is sunlight. If you can't get outdoors early in the morning, have your breakfast near a window, on your balcony, porch or patio.
Rule #11 If you typically have a hard time falling asleep, do not use your bed to watch television, read, write, eat, talk on the telephone, use your laptop or play board games.
Rule #12 Consider avoiding daytime naps if you have difficulty sleeping at night. If you are unsure about napping during the day, discuss it with your doctor.
Rule #13 Avoid foods such as aged cheeses, spices, smoked meats, and ginseng tea near bedtime since they may keep you awake.
Rule #14 Avoid caffeine (such as coffee, tea, chocolate, sodas, and colas) close to bedtime (especially four to six hours before sleep) since they are stimulants and may disturb sleep. The effects of caffeine can remain in the body an average of 3 to 5 hours.
Rule #15 Avoid smoking and other tobacco products. Nicotine is a stimulant that disturbs sleep and should be avoided altogether for health reasons.
Rule #16 Avoid alcohol within six hours of your bedtime since it fragments sleep.
Rule #17 Avoid late and heavy meals within three hours of bedtime. The key is not to go to bed hungry or too full.
Rule #18 Avoid excess consumption of fluids within two hours of bedtime. This can help prevent frequent bathroom trips at night.
