Staying awake till late and then getting up late on weekend may seem relaxing. However, recently, a team of researchers from the University of Arizona in Tucson has pegged it harmful for health. Social jet lag, which occurs due to different sleep patterns on weekends than on a weekday, has been associated with worse mood, increased fatigue and sleepiness, and an overall poorer health. Each hour of social jet lag can result in 11 percent increase in the likelihood of heart disorder.
The American Academy of Sleep Medicine recommends a seven or more hours sleep every night to adults to promote optimal health. Apart from the adequate duration, a healthy sleep is a combination of appropriate timing, good quality, and regularity.
Sleep Regularity Plays a Vital Role in Human Health
The results of the research, which was conducted within the Sleep and Health Research Program, indicate that sleep regularity along with the sleep duration plays a pivotal role in human health. A regular sleep schedule could be treated as a relatively simple, effective, and ineffective preventative treatment for various heart-related diseases as well as several other health issues.
The data used for this research was derived from the community-based study of sleep and healthy activity, diet, environment, and socialization (SHADES), evaluating nearly 1,000 adults aged between 22 and 60 years. Insomnia symptoms and sleep duration were not considered while carrying out the research. Social jet lag was analyzed utilizing questionnaire related to sleep timing and was deduced by subtracting midpoint of sleep on weekdays from that of on weekend.
