Do whales sleep?

Scientists are speculating over sleep patterns of whales; Sperm whales to be exact. Apparently, they believe these whale's brains sleep one half at a time. The two sides alternate until both are rested.

"The researchers, whose study was recently published in Current Biology, noticed the whales performed the mesmerizing drift dives 7.1 percent of the time, usually between 6 p.m. and midnight."

There has been more and more studies involving the sleep patterns of whales, because often times they do not flee when a boat is coming there way. Why would they not move? Because they are asleep? The reason whales sleep near the surface of the water is so they don't have far to go to breathe.

Of course this study is now causing people to question how much sleep you really need for development and such. I don't think they should do that, your body needs sleep. Period. You need sleep for a healthy immune system and to allow your body time to relax and unwind. I should know, I get very little sleep.

Most people say you should sleep about eight hours a night, but there really isn't a magic number to sleep. You know whether you have gotten or not, you can feel it. When you haven't gotten enough you won't be able to fully concentrate and you will run out of steam early on in the day.

Did you know sleep deprivation can cause you to be more hungry throughout the day? It makes sense doesn't it? Food gives you energy. Chew on that one folks.
