Lost Sleep Can't Be Made Up, Study Suggests
If you think staying in bed on the weekends will make up for a weeks' worth of sleep deprivation, think again. A new study finds that going long periods without sleep can lead to a sort of "sleep debt" that cannot simply be undone with a little extra snoozing from time to time.
The study involved a small number of participants, however, so further research would be needed to verify the results.
