Definition
The four most common sleep disorders are insomnia, sleep apnea, restless legs syndrome, and narcolepsy. Additional sleep problems include chronic insufficient sleep, circadian rhythm abnormalities, and “parasomnias” such as sleep walking, sleep paralysis, and night terrors.
African Americans are more likely to have the deadly sleep disorder, obstructive sleep disorder, than Caucasians. Their partners are more likely to tolerate the irregular breathing and snoring that accompany the disorder; consequently, African Americans fail to seek treatment for this disorder that can lead to more serious health problems.
The 2010 Sleep in America poll by the National Sleep Foundation (NSF) revealed significant differences in the sleep habits and attitudes of Blacks:
• Blacks reported getting the least amount of sleep on workdays/weekdays (6 hours and 14 minutes). Interestingly, they also say that they need only 7 hours and 5 minutes of sleep each night to perform at their best during the day, which is significantly less sleep than Asians and Hispanics (7 hours and 29 minutes each).
• Blacks are the most likely to report performing activities in the hour before going to bed every night or almost every night, specifically watching TV (75%) and/or praying or doing another religious practice (71%).
• Whether on weekdays/workdays or non-workdays/weekends, Blacks spend much more time in bed without sleeping than the other ethnic groups (54 minutes on weekdays/workdays and 71 minutes on non-workdays/weekends).
• Blacks (10% each) are ten times more likely to report having sex every night than Asians (1%) and 2.5 times more likely than Whites (4%).
• Blacks/African-Americans (17%) are more likely than Whites to report doing job-related work in the hour before bed, among those employed.
• Blacks report losing sleep every night over personal financial concerns (12%) and employment concerns (10%) at a higher rate than Whites (6% and 7%).

Preventions
Good sleep habits can help you get a good night’s sleep. Here are some tips:
• Try to go to bed at the same time every night and get up at the same time every morning. Try not to take naps during the day because naps may make you less sleepy at night.
• Try to avoid caffeine, nicotine, and alcohol late in the day. Caffeine and nicotine are stimulants and can keep you from falling asleep. Alcohol can make you wake up later in the night.
• Get regular exercise. Try not to exercise close to bedtime because it may stimulate you and make it hard to fall asleep. Experts suggest not exercising for 3 hours before the time you go to sleep.
• Don’t eat a big meal late in the day, although a light snack before bedtime may help you sleep.
• Make your sleeping place comfortable. Be sure that it is dark, quiet, and not too warm or too cold. If light is a problem, try a sleeping mask. If noise is a problem, try earplugs, a fan, or a “white noise” machine to cover up the sounds.
