'Social Jet Lag' Is Not Good For The Health

'This suggests that a regular sleep schedule may be an effective, relatively simple, and affordable preventative treatment for heart disease as well as many other health problems'.

While the American Academy of Sleep Medicine firmly recommends that adults should sleep seven-plus hours a night, the issue of when one should sleep is not as empirically established.

These results indicate that sleep regularity, beyond sleep duration alone, plays a significant role in our health.

To illustrate, on weekdays an individual goes to sleep at 12 a.m and wakes up at 7 a.m.to report to work. These effects are independent of the duration of the sleep and insomnia symptoms, which are associated with both social jet lag and health.

Germany scientist Till Roenneberg from Ludwig-Maximilian University, who coined the term "social jet lag" told Reuters that he was not surprised by the Pittsburgh study results.

Furthermore, sleeping in longer was found to have no health benefit if you have gone to bed at a later time than usual, according to the University of Arizona in Tucson.

The data for the study were collected as part of the Sleep and Healthy Activity, Diet, Environment, and Socialization study, which is a community-based survey of more than 1,000 adults.

Smith slams Australia's bowling performance after draw
Earlier, New Zealand made a good start after opting to bat with Martin Guptill (26) and Ronchi looked settled from the word go. Chasing target of 235 from 33 overs, Australia were 53/3 in 9 overs when rain gods prevented the match to be completed.

Several studies over the past few years have shown a link between sleep deprivation and heart diseases.

Dr. Grandner and colleagues evaluated social jet lag using the Sleep Timing Questionnaire, and they calculated it by subtracting the weekday sleep midpoint from the weekend one.

More specifically, with each hour of social jet lag, the researchers found an 11.1 percent increase in the likelihood of developing heart disease.

Her findings come from a study involving almost 1,000 adults aged from 22 to 60.

Overall health was self-reported using a standardised scale, and survey questions also assessed sleep duration, insomnia, cardiovascular disease, fatigue and sleepiness.

Scientists discovered that 85 percent of people wake up later on the weekends, and they have linked the pattern to bad moods and chronic fatigue. They were also 22 percent more likely to rate their overall health as good, not excellent, and 28 percent more likely to rate it as poor.

After analyzing the results, the team concluded that each hour of social jet lag could be linked to a 22.1 increased chance of having just a "good" sleep.
