Seasonal Changes In Nature Can Disrupt The Sleep Cycle In Adolescents

Seasonal Changes In Nature Can Disrupt The Sleep Cycle In Adolescents.
When the days flower longer in the spring, teens skill hormonal changes that persuade to later bedtimes and associated problems, such as lack of sleep and mood changes, researchers have found. In a con of 16 students enrolled in the 8th grade at an upstate New York mesial school, researchers collected information on the kids' melatonin levels.

Levels of melatonin - a hormone that tells the body when it's nighttime - normally origin rising two to three hours before a woman falls asleep. The study authors found that melatonin levels in the teens began to flight an average of 20 minutes later in the spring than in the winter.

The teens also reported an regular 16-minute delay in sleep onset and an average 15-minute reduction in take duration in spring compared to winter. "This is a double-barreled problem for teenagers and their parents," investigate author Mariana Figueiro, an associate professor at the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, NY, said in a dirt release from the institute.

So "In counting up to the exposure to more evening daylight, many teens also contend with not getting enough morning light to stimulate the body's biological system, also delaying teens' bedtimes," she explained. This hold up in getting to sleep may lead to nap deprivation and mood changes, and may also increase the risk of obesity and possibly lower school grades, Figueiro noted.

The chew over is published in the July issue of the journal Chronobiology International. "This modern development study supplements previous work and supports the general hypothesis that the entire 24-hour standard of light/dark exposure influences synchronization of the body's circadian clock with the solar broad daylight and thus influences teenagers' sleep/wake cycles," Figueiro stated in the news release near to health. "As a mixed rule, teenagers should increase morning daylight exposure year round and decrease eventide daylight exposure in the spring to help ensure they will get sufficient sleep before going to school," she advised.
