Sleep

Ahhh, sleep. There's nothing better than a nice, long, uninterrupted. Awwgh. I can't sleep when there's. But d'ya ever notice: noise doesn't wake everyone. Now [scientists:researchers] have a better idea why. Because sound [sleepers:dreamers] show a certain brain rhythm when they doze, findings published in the journal Current Biology.To study the brain waves of a good night's sleep, scientists invited volunteers to snooze in the lab. While the subjects caught some Zs, the researchers [monitored:examied] their brain activity. They then [subjected:questioned] the sleepers to or [NOISE]. And they found that those who were able to slumber [straight:direct] through all the showed more short bursts of faster brain waves. This activity, the scientists say, is the brain's way of [blocking:stopping] out the and the while you're trying to rest.The scientists don't yet know of any way to boost those sleep-saving brain waves. So until then, shut the door, make sure the late show's on a timer, and try to have sweet dreams.
