Sleep is a basic necessity of life and it is as important to our health as air, food and water. When we sleep well, we wake up feeling energetic, alert and ready to face daily challenges. When we don’t every part of our lives can suffer.
A survey made by the 2002 National Sleep Foundation (NSF) in America found that 74 percent of American adults are experiencing a sleep problem a few nights a week or more and 39 percent get less than 7 hours of sleep each night and want to have a sleep during the day.
Getting enough continuous quality sleep influences how we feel and perform next day. Getting enough sleep refers to the amount of sleep you need not to feel tired next day. Although sleep experts generally recommend an average of 7-9 hours each night, some people can get along with less while others need as many as ten hours to feel energetic next day. Sleep requirements vary(变化)over the life cycle. Newborns and babies need a lot of sleep and have several periods of sleep throughout a 24-hour time period. Teenagers’ sleep patterns turn to a later sleep-wake cycle, but they still need around 9 hours of sleep. Throughout adulthood, even as we get older, we need 7-9 hours of sleep. Sleep patterns may change, but the need for sleep remains the same.
According to the 2002 poll. Over 80 percent of American adults believe that not getting enough sleep leads to poor performance at work, risk of injury, poor health and difficulty getting along with others. Often, people become easily annoyed due to lack of sleep. Recent research suggests that lack of sleep also leads to approximately 100,00 sleep-related traffic accidents each year and results in 1,500 deaths.
If you are having sleep problems, turn to a sleep diary published by the National Sleep Foundation. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can find some reasons for poor sleep. Establishing a regular bed and wake-up schedule may also help you sleep well. Besides, talking to your doctor or a sleep specialist is of great help. Most sleep disorders can be successfully treated once properly diagnosed(诊断).
