â€˜Social Jet Lagâ€™ Can Figure Into Obesity
As many working people and students can attest, the sound of the alarm clock in the morning can mean an unpleasant jolt out of a nice deep sleep. And disrupting the bodyâ€™s internal clock in this way can lead to a higher risk of becoming overweight or obese, according to a new European study published in the journal Current Biology.
Led by Till Roenneberg at the University of Munich, the study evaluated the relationship between social jet lag â€” which the researchers describe as the discrepancy between oneâ€™s internal and social clocks â€” and body mass index. The researchers found that those who disrupted their biological rhythms, which are determined in part by genetics, had a greater chance of not only becoming overweight or obese but also more likely to smoke and drink more alcohol and caffeinated beverages.
