Insomnia cap

    An 'insomnia cap' is supposed to help insomniacs sleep by lowering the temperature of the brain.
    Increased metabolism in the frontal cortex of the brain is associated with insomnia; by cooling that area of the brain the metabolism is reduced. The idea is to create a special cap that will cool the cortex with tubes of circulating water. The insomniacs will not only fall asleep faster than the non-insomniac people, they also will stay asleep for 89 percent of the time.
