Nowadays, more and more people are unable to sleep due to various reasons. What will you do if you have trouble going to sleep? Try a glass of warm milk, still no luck? Try counting sheep, "One, two, three" It is late but you are still awake. Are you supposed to take a sleeping pill? No, because if you take it, you will probably depend on the drugs. So you lie awake all night hoping that the new workday will arrive soon.
A new study has found that you might fall asleep quicker and stay asleep longer if you try "cerebral(大脑的)hypothermia(低体温症)." No, cerebral hypothermia is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Daniel Buysse of the University of Pittsburgh Medical School led the study. They examined 12 people who had insomnia. Twelve others had no sleep problems. Each of them wore a soft plastic cap on their heads at bed time, which had tubes inside filled with water. The first two nights of testing, the patients wore no water caps. During the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for two nights. On the final two nights of the study, the temperature of the water was made much cooler.
The researchers found that the water caps did not help the insomnia patients until the temperature was about 14CC.Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads.
Dr. Nofzinger and Dr. Buysse noted that this was only the beginning of the brain temperature study. But they believe they have discovered something important that needs more research. They presented their test results in June at a meeting of the Associated Professional Sleep Societies in Minneapolis, Minnesota.
