If your weekend mantra is "party hearty," but on weekdays you're strictly 9 to 5, you're a candidate for Social Jet Lag. And that doesn't mean you're one step behind on your Facebook posts or retweets.
Social Jet Lag happens when there's a habitual discrepancy between your workweek sleep cycle and your weekend habit of going to bed later and sleeping in.
Whether you're a morning person or a night person, that combo disrupts your internal body clock (circadian rhythm) and throws your hormones out of whack, creating a metabolic mess that ups your risk for a number of health issues.
Looking at people ages 30 to 54, researchers found that even weekenders with just a little shift in sleep-awake times had lower levels of good HDL cholesterol, higher levels of triglycerides, and were more often insulin-resistant and obese.
The German researcher who coined the term Social Jet Lag (SJL) in 2006 found that only 10 percent of people without SJL smoked, but 60 percent of folks with a four-hour shift from their natural circadian rhythm did.
So if you're struggling to lower your LDL cholesterol, control your blood pressure, quit smoking, or lose weight, ask yourself if SJL could be making it harder.
Try to keep your weekend bedtime within 30 to 45 minutes of your weeknight schedule, and make sure you get 7 to 8 hours of sleep every night.
It'll be worth it. You'll have more energy on both weekdays and weekends and live a longer, healthier life.
