It sounds like the perfect weekend, stay up late and sleep-in for hours. However that “social jet-lag” has a negative impact on the rest of your week and your overall health.
Researchers at the University of Arizona-Tuscon found “social jet lag” makes us more tired than if we maintain a regular schedule all seven days. That extra exhaustion can lead to serious illness.
In the study of adults aged 22 to 60 they found an hour of social jet lag meant a 28% increase in the likelihood of self-reported fair to poor health and an 11% increase in heart disease over people who went to bed at the same time every night.
