Not only does sleep deprivation lead to health problems , too much sleep can result in the same . Two new studies show , too little or too much sleep can increase the risk of depression . The researchers report in the journal Sleep , the amount of sleep that does not conform to activate genes associated with depression .
A study involving more than 1,700 adult twin pairs to compare symptoms of depression a person with a twin. Those who get enough sleep seven to nine hours per day , only 27 percent who reported experiencing symptoms of depression .
This figure is much higher in those who sleep less ( about five hours per day ) were 53 percent reported symptoms of depression . And 49 percent of those with excess sleep ( approximately 10 hours per day ) .
" Sleep duration is too short and too long to activate genes associated with depressive symptoms , " said lead researcher Nathaniel Watson , professor of neurology and co-director of the University of Washington Medicine Sleep Center in Seattle . Therefore , he added , the optimal sleep duration is the most effective way for the treatment of depression .
Another study conducted an analysis on 4,100 young people aged 11 to 17 years . The study found that sleeping less than six hours each night are the main factors that increase the risk of depression .
" These results are important because lack of sleep is a major precursor for adolescent depression , occurs before the symptoms of major depression and other mood disorders arise , " said Robert Roberts , a professor of behavioral science from the School of Public Health at the University of Texas Health Science Center at Houston .
M. Safwan Badr , president of the American Academy of Sleep Medicine says , healthy sleep is necessary for physical, mental , and emotional . " This study emphasizes , we can make health investments through adequate sleep , " he concluded .
