Consequences of Social Jet Lag



As technology is rapidly bringing the world ‘virtually’ closer by keeping us connected, our real world counterparts are slipping into the blankness of disconnection, moving further away from each other unknowingly. Both outcomes can, directly or indirectly, attributed to the widespread social networking wave. Social media platforms today, have nearly replaced the need to actually meet someone in person, owning mainly to the time and convenience factors, which are both voraciously sought after in personal as well as professional life.

People tend to keep their Facebook account and many other social media sites open even at work till they log-out eventually only to switch on to their mobiles, once they are out. The result is late nights chatting with friends and digitally hooked to the maximum. Even if the ill effects are uncommonly known, the overpowering attraction and easy habit forming nature of these platforms make it a tough hurdle to overcome, which makes it one major source of lifestyle related heath concerns. The short as well as the long-term toll of such habits is grave enough to be considered seriously.

Irregular sleep patterns associated with intense weekday work may drive diabetes and obesity. And sleep deprivation boosts the risk of hypertension, Alzheimer’s, even cancer. Here is an article by Eric Ness for Discover Magazine highlighting various cases of health issues that have been reported by some researchers.

If you ever have the impulse to smash your alarm clock, Ludwig-Maximilians University biologist Till Roenneberg understands. This year he described the increasingly common phenomenon of “social jet lag,” experienced by those who sleep short on workdays, then stay up later but sleep longer on weekends. If that is your pattern, you are more likely to be depressed and obese. “Sleep is one of the most underrated phenomena in modern society’’ Roenneberg says. A growing body of research is showing that if you don’t get enough or get it at the wrong times, you expose yourself to a wide range of health consequences.

Eve Van Cauter, an endocrinologist at the University of Chicago, began untangling the connection between sleep deprivation, diabetes, and obesity more than a decade ago. This year her team discovered that sleep deprivation impedes the metabolism of glucose, the sugar that powers the body, in fat cells by a startling 30 percent. Lack of sleep affects appetite, too: A 2012 Swedish brain-scan study identified heightened activity in the right anterior cingulate cortex—a brain region associated with hunger control—in the sleep-deprived.

Sleep loss is increasingly being implicated in other health conditions as well. A Penn State study showed that short sleep combined with insomnia heightened the risk of hypertension. European data linked restless or otherwise troubled sleep in older adults to a 36 percent increased risk of Alzheimer’s. More unexpected, researchers at the University of Wisconsin at Madison uncovered a link between sleep apnea and cancer mortality: Cancer deaths among patients with severe apnea were five times higher than among those without.

Perhaps the biggest sleep news from the past year, though, involves the significant health penalties of varying proportions when we sleep, regardless of the total amount. Anecdotal reports had suggested that shift work consistently working nights or rotating between night and day contributes to bad health. But how? A study by Harvard’s Orfeu Buxton, a neuro-scientist, limited participants to less than 6 hours of sleep and then reconfigured their day so it stretched for 28 hours instead of the expected 24. The result was dysfunction of the pancreas, which produces the insulin that regulates sugar in the blood. As a result, the strain of extreme time shifting led to a form of hyperglycemia that foreshadows diabetes.

Even those with only slightly altered sleep schedules pay a price. According to Roenneberg, a third of the population in his database suffers from two or more hours of social jet lag, and 69 percent reported at least one hour of social jet lag. That might be enough, studies suggest, to increase the risk of becoming overweight or obese by 33 percent. “It took me about 50 years of my life to understand what an alarm clock means,” Roenneberg concludes. “It means that you haven’t slept your biological sleep to the end.”

There is nothing wrong with social media, it is up to us to utilize this amazing new technology keeping a check on our health. What good would to be hooked onto a saline, on a hospital bed, while you use your other hand to update your ‘health’ status? Or, worse, when you are waiting for your next chemotherapy session? Friends aren’t going anywhere, neither are you. So take the day off and get a good night’s sleep.
