The price we pay for sleep deprivation

We are a nation of sleep-deprived people and all ages suffer in various, unhealthy ways. For children, sleep deprivation can lead to behavior problems, trouble focusing and learning in school and it can affect their immune systems. Chronic tiredness makes it harder to cope and process what's going on around you. When children enter the teen years, sleep becomes a bigger issue. Teen's circadian rhythm, or internal body clock, tells them to stay awake later and sleep later than children and adults do. Only 15 percent of teenagers get the recommended sleep they need.

For adults, sleep loss is even more serious. It accumulates over the years and has been shown to contribute to several chronic diseases including heart disease, diabetes, high blood pressure, depression and obesity. Adulthood is also when sleep-related disorders, such as insomnia or sleep apnea, are more likely. During menopause, women often experience night sweats and insomnia due to changing levels of hormones. As men age, an enlarged prostate can lead to more frequent trips to the bathroom overnight. Certain medications can also disrupt sleep, such as those for heart arrhythmia, high blood pressure and asthma.

Here are the recommended hours of sleep we should get throughout our lifetime, according to the National Sleep Foundation:

Infants: up to 16 hours total, including naps
Toddlers (1-3 yrs): 12-14 hours, including naps
Preschool (3-5 yrs): 11-13 hours, most do not nap after age 5
School-age (5-12 yrs): 10-11 hours
Teens: 8.5-9.5 hours
Adults: 7-9 hours
