Are you suffering from social jet lag?

Keeping your week-day bedtime over the weekend may be more important for your health than you realise. By going to bed and waking up later on weekends, you might be giving yourself “social jet lag”, associated with poorer health, worse mood and increased fatigue and sleepiness.

Long-term, social jet lag can even increase your likelihood of heart disease.

“These results indicate that sleep regularity, beyond sleep duration alone, plays a significant role in our health,” said lead author Sierra B. Forbush from the Sleep and Health Research Program at the University of Arizona in Tucson.

The good news is that it’s easy to fix: just keep your bed time and wake up time over the weekends — as long as you have a healthy sleep schedule to begin with. If not, your first step will be to implement one, making sure you get 7-9 hours of sleep each night.

“This suggests that a regular sleep schedule may be an effective, relatively simple, and inexpensive preventative treatment for heart disease as well as many other health problems,” said Forbush.
