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 burgeon longer in the spring, teens savoir vivre hormonal changes that spend to later bedtimes and associated problems, such as lack of sleep and mood changes, researchers have found In a review of 16 students enrolled in the 8th grade at an upstate New York medial school, researchers collected information on the kids' melatonin levels.

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

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

So "In combining 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". This put off in getting to sleep may lead to sleep deprivation and sense changes, and may also increase the risk of obesity and possibly lower school grades.

The weigh is published in the July issue of the journal Chronobiology International. "This latest study supplements former work and supports the general hypothesis that the entire 24-hour pattern of light/dark publication influences synchronization of the body's circadian clock with the solar day and thus influences teenagers' sleep/wake cycles," Figueiro stated in the item release as an example. "As a general rule, teenagers should expand morning daylight exposure year round and decrease evening daylight exposure in the cause to occur to help ensure they will get sufficient sleep before going to school," she advised.
