How Cooling the Brain May Help People Sleep
11 July 2011
FAITH LAPIDUS: This is SCIENCE IN THE NEWS, in VOA Special English. I’m Faith Lapidus.
BOB DOUGHTY: And I’m Bob Doughty. Today, we tell how cooling the brain may help people who have trouble going to sleep. We also tell about two endangered animals that are in danger of disappearing forever.

FAITH LAPIDUS: Are you having a problem going to sleep? Try drinking a glass of warm milk. If that does not work, listen to some soft, beautiful music. Still no luck? Try thinking about sheep jumping over a fence. Count them to yourself. “One, two, three, four…one hundred ninety five, one hundred ninety…”
It is late at night and you are still awake. Should you take a sleeping pill? People who take pills often come to depend on the drugs. So you lie awake knowing that the new work day will soon arrive. If this happens to you for at least one month, you may have primary insomnia. There are millions of you…us…around the world.
BOB DOUGHTY: A new study has found that you might fall asleep quicker and stay asleep longer if you try “cerebral hypothermia.” 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 twelve people who had insomnia. Twelve others had no sleep problems. Each of them wore a soft plastic cap on their heads at bed time.
