WAKE-UP CALL|So much for making up lost sleep on the weekend. Hitting the snooze button on Saturday and Sunday for an extra three hours threw off the circadian rhythms (the body’s internal clock) of 16 volunteers in a study by the Sleep Research Society, reported on in this month’s Women’s Health magazine. The volunteers were surveyed after waking up at their normal time on the weekend and then after sleeping as late as they wanted. The late sleepers had a hard time getting out of bed on Monday morning.
SLEEP ON THIS|While on the topic of snoozing, if you’ve got a major meeting or exam tomorrow, you might want to kick your spouse out of the bed tonight. For a University of Vienna study, eight young couples wore monitors to measure how often they awoke while sleeping together for 10 nights and then apart for another 10. They took cognitive tests after each session. Both genders woke up more often and performed worse on tests after sleeping together.
