Young parents and workaholics are very familiar with the effects of sleep deprivation, and almost everyone is agreed – it’s not the most pleasant place to be! Anyone who has ever tried to be, or had to be, awake continuously for several days and nights will know how a stretch of busy time without a nap reduces us to clumsy, incoherent creatures in a daze. But did you know that dolphins have the incredible ability to stay constantly awake – and alert – for more than two weeks? So how do they do that? This is the question Brian Branstetter, a marine More >
It’s the season of hibernation, something I’ve always wished I could do. Oh, to wrap up in a ball, sleep away the winter, and wake to a beautiful spring day – like Bambi!

Do you know people who swear that they can live on a few hours of sleep a night and be able to fully function the next day? Perhaps you’re one of these people. Well it seems that you really can’t “fully function” on less sleep.
Researchers at the University of Wisconsin- Madison conducted tests with rats that were kept up past their normal bedtime. The rats were given objects to play with to keep them awake. During play, electrodes were implanted in their brains to measure brain activity. The results were interesting.

Have you ever wished there were more hours in the day? I know someone who insists on extending his days by consuming energy drinks. In his opinion, sleeping is a waste of precious time. Unfortunately, for most humans, 8 hours of sleep is required to function properly. Some people can manage with far less sleep, which for those of us who really NEED 8 hours of shut-eye, is hard to imagine. For me, sometimes it seems even 8 hours doesn’t suffice, which is evidenced by my morning alarm-snooze-alarm-snooze routine, and my sofa sleeping habit in the evenings.
