Re: Bingo! Sleep mysteries unfold

Here's another article on sleep from

Here's a quote

"Insomnia seems to be caused by excessive metabolic activity in the
brain's frontal cortex. For deep, refreshing sleep to occur, the
frontal cortex has to rest, said Dr. Eric Nofzinger, a professor of
psychiatry at the University of Pittsburgh.

Research on brain injuries has shown that cooling the brain reduces
metabolic activity. Nofzinger and his colleagues decided to try the
same concept on insomnia by designing a device that gently cools the
frontal cortex during sleep. "

Note the metabolic connection.
