People who struggle to get out of bed on a Monday morning, seems to be suffering from social jet lag, revealed a study by Rush University in Chicago. Sleeping at weekend could leave you too tired to start of the working week with numerous lingering sleepy till following days.
The instant effects of the condition may include poorer memory and reaction times that elucidating a Monday morning feeling of sluggishness. A shift of just two hours, repetitive changes to sleep patterns could also make you fatter and more likely to turn to cigarettes and caffeine. The study participants were asked to hit button when they saw a bullseye appear on a screen.
Predictably, the study participants were slower in the mornings in comparison to in the evenings. But, they were also far slower after a pattern of sleep analogous to getting up early on a Monday morning after a weekend of late starts. The phrase social jet-lag was invented by German researcher Till Roenneberg.
He has shown that the phenomenon can take a stocky toll on health by elevating the likelihood of drinking, smoking and relying on caffeinated drinks. While travel-induced jet lag is something most of people only tolerate occasionally, social jet-lag can make itself felt every week. The study was reported in the journal Applied Ergonomics.
Helen Burgess, lead author of the study , explained the weekend sleep in is just the process by which people shift their clocks later, and it would not be a problem except for that rude awakening on Monday morning when all of a sudden they need to shift earlier.
Changes in sleeping patterns affect reaction times that a shift of just two hours can leave you worse off in the week, suggest a study.
