Researchers at UC Berkeley have shown that sleep deprivation amplifies anxiety in people prone to worry. In a study written up in Science Daily, the researchers found that a single sleepless night greatly ramped up neural activity in two brain regions associated with the processing of emotion.
Sleeping on the couch isn’t always a bad idea. Some insomnia sufferers are light sleepers prone to high-frequency brain activity even during the deeper stages of sleep, or so the experts say. We pick up on information in the environment that normal sleepers readily tune out.
The problem may be that there are disturbances in the bedroom itself.
Even people with insomnia sleep well from time to time. “I know on a sunny day after I’ve had a good night, I’m almost high,” Mary, a writer and former teacher, told me as we sat talking over cups of tea.
The day is wonderful after a good night’s sleep. But what about mornings after really bad nights?
