The findings showed that each hour of social jet lag -- which occurs when one goes to bed and wakes up much later on weekends than during the week -- is associated with an 11 per cent increase in the likelihood of heart disease. Social jet lag also leads to poorer health, worse mood, as well as increased sleepiness and fatigue. "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," Forbush added. Social jet lag was assessed using the sleep timing questionnaire and was calculated by subtracting weekday from weekend sleep midpoint. Overall health was self-reported using a standardised scale, and survey questions also assessed sleep duration, insomnia, cardiovascular disease, fatigue, and sleepiness.
