What are sleep disorders?
Sleep disorders are conditions that impair your sleep or prevent you from getting restful sleep and, as a result, can cause daytime sleepiness and other symptoms. Everyone can experience problems with sleep from time to time. However, you might have a sleep disorder if:
You regularly experience difficulty sleeping.
You are often tired during the day even though you slept for at least seven hours the night before.
You have a reduced or impaired ability to perform regular daytime activities.
There are more than 100 million Americans of all ages who are not getting an adequate amount of sleep. Sleep is very important. Not getting enough sleep can have untoward consequences on school and work performance, interpersonal relationships, health and safety.
How much sleep is necessary?
Experts generally recommend that adults sleep at least seven to nine hours per night, although some people require more and others require less.
A recent National Sleep Foundation Sleep in America poll found that adults (ages 18-54) sleep an average of 6.4 hours per night on weekdays and 7.7 hours on weekends. The poll showed a downward trend in sleep time over the past several years. People sleeping less hours tend to use the internet at night or bring work home from the office.
The National Sleep Foundation also reported that older adults (age 55-84) average seven hours of sleep on weekdays and 7.1 hours on weekends. Sleep is most often disturbed by the need to use the bathroom and physical pain or discomfort in older adults.
A downward trend in sleep time has also been observed in children. Optimal sleep time varies by age. An earlier Sleep in America poll found a discrepancy between recommended and actual sleep time in children, with actual sleep time 1.5 to two hours less than recommended. Caffeine consumption caused a loss of three to five hours of sleep and having a television in the bedroom contributed to a loss of two hours of sleep each week in children.
