Researchers at the University of Pittsburgh School of Medicine discovered that wearing a cooling plastic cap that covers your forehead will help you get to sleep faster and sleep longer. The study looked at 24 subjects, 12 of with insomnia and 12 with normal sleep patterns.
Those insomniacs who wore the caps at their highest cooling level fell asleep within 13 minutes and slept most the night, just like the normal people. The researchers believe the cooling caps slow the metabolism in the front part of the brain which is overactive in those with insomnia. [LA Times; Valeriy Lebedev/Shutterstock]
