The normal need for between 7 to 9 hours of sleep each night is apparently required to prevent depressive symptoms from being triggered. Research from two new studies in the j…ournal of Sleep have found that the genetic potential for depression is activated by too little, or conversely, too much sleep. "Healthy sleep is a necessity for physical, mental, and emotional well-being," said American Academy of Sleep Medicine President Dr. M. Safwan Badr. "This new research emphasizes that we can make an investment in our health by prioritizing sleep."The first of these two studies looked at 1,788 adult twins. The research revealed that a gene seems to be activated by variation in sleep duration that links to depressive symptoms. The participants in the study were 894 same-sex twin pairs selected from the University of Washington Twin Registry and self-reported both their sleep durations and depressive symptoms. A total of 192 male and 412 female monozygotic (identical) pairs were compared to a control group of 81 male and 209 female dizygotic (fraternal) pairs for genetic factors.The monozygotic twins with an average of 8 hours of sleep per night showed a heritability of depressive symptoms of 27 percent. But when the total amount of sleep dropped to 5 hours a night the genetic factor increased to 53 percent. For those twins sleeping 10 hours a night the genetic influence on depression was 49 percent. "We were surprised that the heritability of depressive symptoms in twins with very short sleep was nearly twice the heritability in twins sleeping normal amounts of time," said lead researcher Nathaniel Watson, M.D., associate professor of neurology and co-director of the University of Washington Medicine Sleep Center in Seattle. "Both short and excessively long sleep durations appear to activate genes related to depressive symptoms.""The study's findings suggest that optimizing sleep may be one way to maximize the effectiveness of treatments for depression, such as psychotherapy," he said.In a second study of 4,175 children between the ages of 11 and 17 it was found that those who slept less than six hours per day were at risk of having a major depression. Alternately, having a major depression raises the possibility of being sleep deprived. This is the first research to demonstrate the reciprocal relationship between sleep deprivation and depression among adolescents. In other words, if adolescents sleep less they will get depressed, which in turn causes them to lose sleep. "These results are important because they suggest that sleep deprivation may be a precursor for major depression in adolescents, occurring before other symptoms of major depression and additional mood disorders," said lead researcher Robert E. Roberts, Ph.D., professor of behavioral sciences in the School of Public Health at the University of Texas Health Science Center in Houston, Texas. "Questions on sleep disturbance and hours of sleep should be part of the medical history of adolescents to ascertain risk."Watson NF; Harden KP; Buchwald D; Vitiello MV; Pack AI; Stachan E; Goldberg J.

If you are one of those parents that make your 11-13 year old children go to sleep at 9:30pm maybe you shall reconsider it. it is a proven fact that most people who stay up at… least until 10:00pm become more calm,you become more inquisitive, and you have an easier time going to bed, which can result in calmness as presented before. when you have them go to bed around 9:15pm-9-40pm they feel forced to go to bed at that time even though they're body is not used to it-(not tired). this is just a reminder that if you have children ranging from 11 to 13 years old maybe even 14, it will do them a whole lot of good to keep them up to at least 10:00pm. --Sincerely Dr.Smith, (MORE)
