One hour of additional sleep at night may be your best defense against the common cold

Why is it that when you are working hard and multitasking like a superhero, you tend to get sick? A recent study by Sheldon Cohen from Carnegie Mellon University examined the relationship between sleep habits and susceptibility to the common cold. The results indicated that there is a direct correlation between how much sleep you get per night and the likelihood that you will be stuck in bed with a rhinovirus after just two weeks of inadequate sleep.
French philosopher Gaston Bachelard wrote in 1960 that "sleep opens within us an inn for phantoms." Recent research agrees, finding that some sleepers shriek or even gorge themselves without knowing it. These sleep-disorder sufferers experience neural glitches that mix conscious and unconscious states. Scientists are now searching for the physiological underpinnings in hopes of developing better drug therapies.

It's not necessarily laziness that makes people hit the "snooze" button in the morning. Most likely, your body clock is mismatched with the demands of your life.
Your clock is controlled by the suprachiasmatic nucleus, a part of the brain that controls the body's biological rhythms. But, says Jean Matheson, a sleep-disorders specialist at Beth Israel Medical Center in New York, these preset natural rhythms often don't align with daily realities—work or school start times cannot be adjusted to fit a person's sleep schedule.

Next time you're caught napping in your cube, or some little hideaway in your office, just cite the work of Harvard Medical School scientist Matthew Tucker and his colleagues, which appears in the latest issue of the journal Sleep, then tell your colleague or boss to scurry away.

Although they may have other talents, few astronauts are much good at sleeping in space. NASA researchers have been studying the problem by hooking up space shuttle crews to all sorts of sleep-monitoring devices. The mystery remains unsolved, but one surprising discovery has been made: There's virtually no snoring in space.
