Social Jet Lag And Your Health

Social jet lag – the habit of going to bed later and waking up later on weekends than during the week – isn’t good for you. Researchers at the University of Arizona in Tucson have reported preliminary results of a study showing that no matter how much sleep you get on weekends, every hour of social jet lag is linked to an 11 percent increase in the likelihood of heart disease. Overall, the investigators found that social jet lag is associated with poorer health, worse mood, chronic fatigue and increased sleepiness. To arrive at these conclusions they recruited 984 adults between the ages of 22 and 60 and analyzed their responses to survey questions about sleep duration, insomnia, cardiovascular disease, fatigue, and sleepiness. They found that with each hour of social jet lag the survey respondents were 22 percent more likely to describe their health as “good” rather than “excellent” and were 28 percent more likely to say their health was “fair or poor” instead of excellent. The researchers reported seeing more social jet lag among high school graduates compared to college graduates and found that it was less common among African Americans, unemployed respondents and those with lower incomes.
