Feeling tired? You may be socially jetlagged, study suggests

(Relaxnews) - Hectic schedules, strict work demands, and a busy social life can clash with your biological rhythms, resulting in what researchers are now calling social jetlag.

A new study published last week from LMU University in Munich, Germany, suggests that ignoring the 24-hour circadian clock -- in which sunlight helps regulate your body's natural rhythms -- to keep up with social and work demands, can result in health problems. The consequence? Chronic fatigue, reliance on caffeine, alcohol, and cigarettes, and thicker waistlines - especially if you already have a natural tendency toward obesity.
