Why sleeping in on weekends may harm your health – Social Jet Lag.

Most people like me are guilty of stealing extra hours of sleep at weekends. For me, that is part of why I do TGIF(Thank God its Friday)… basically, more sleep! Once its weekend, we love to sleep in later than we do on weekdays. It is called social jet lag.

Research has over time shown that social jet lag may have negative effect on the body. A new study was recently carried out on social jet lag. The study suggests that sleeping in on weekends may cause heart disorders, worse mood and a generally poor health. The study was led by Dr. Michael. A. Grandner, director of the Sleep and Health Research Program at the University of Arizona, Tucson. It was done on data from over nine hundred adults between the ages of 22 and 60. Measures of their fatigue and sleepiness were also collated.

The study revealed relationships between social jet lag and worse mood, fatigue, sleepiness and a poorer health in general.

Also, every hour of social jet lag was associated with a 22.1 percent increase in the likelihood of having just “good” health and 28.3 percent increase of having “poor” health when compared with “excellent” health.

The next time you are about to slip further in between the sheets, remember this article and fight the temptation to snooze your alarm. The results of the study has shown that beyond the number of hours spent sleeping, the regularity of the sleep plays a major role in our health.

The American Academy of Sleep Medicine (AASM) has given a recommendation that adults have at least seven hours of sleep each night for “optimal” health. Consistency in sleep is going to bed about the same time and waking about the same time is also advisable.
