Cooling your head using a special cap containing cold water could be the best way to overcome insomnia instead of taking medical pills, a new study presented during the annual Sleep 11 meet said.
The researchers, led by Dr Eric Nofzinger of the University of Pittsburgh School, said that cooling your head will lower the brain's temperature, and thereby reducing its activity, and hence could help in going to sleep.
The researchers experimented on 12 insomniacs and 12 healthy people as the control group and gave them special soft caps fitted with tubes through which cold water circulated at different speeds. The researchers found that those who suffered from insomnia took just 13 minutes to fall asleep compared to the 16 minutes needed for the healthy patients.
"The most significant finding from this study is that we can have a beneficial impact on the sleep of insomnia patients via a safe, non-pharmaceutical mechanism that can be made widely available for home use by insomnia sufferers", Dr Nofzinger said.
