Stress-induced insomnia can be predicted by looking at the brain’s electromagnetic waves during sleep, researchers have found.
A study at the University of Concordia in Quebec looked at the sleep behavior and brain activity of 12 students before and during exam time, according to an article on the UPI website.
Those who produced a large number of electromagnetic waves, thought to block outside disturbances, were likely to enjoy deeper sleep states. Those who had fewer of these waves, or spindles, seemed to be more susceptible to stress-induced insomnia.
“We are not all equally armed when facing stress, in terms of how we can manage our sleep,” says Thien Thanh Dang-Vu, the lead study author. “Some people are more vulnerable than others.”
The study was published in the journal Frontiers in Human Neuroscience.
