If you tend to keep to a regular sleep schedule during the week, but then turn into a late-night party animal on the weekends, you may be risking your health, new research suggests. Sleep experts call this sleep pattern “social jet lag,” a mismatch between your body’s biological clock and your actual sleep pattern due to social activities. In the new study, researchers found the pattern is linked with heart disease, depression and other problems. The researchers evaluated nearly 1,000 adults, ages 22 to 60, asking about their sleep duration and sleep quality on weekdays and weekends. They also asked about any insomnia and about their general health. “With social jet lag, you are more likely to have heart disease, to feel fatigued, to feel tired and to have a worse mood,” said study lead author Sierra Forbush, a research assistant at the University of Arizona. With every one hour that sleep is shifted, the researchers found, you are about 11 percent more likely to have heart disease, as diagnosed by a doctor, the study found. Each one-hour shift was also linked with a 28 percent higher likelihood of people reporting their health as poor or fair compared to excellent. Those with social jet lag were also more likely to be in worse moods and to be sleepier and more fatigued. Even when Forbush and her associates took into...
