The article discusses research on the link between sleep patterns and obesity carried out by Till Roenneberg, a professor at the University of Munich's Institute of Medical Psychology in Germany. It examines his study of what he calls "social jet lag," referring to the difference between the amount of sleep needed and the amount of sleep attained. The author considers how waking up to alarm clocks disrupts biological and circadian rhythms.
