Lack of sleep for (even) one night can bring about a 30% rise in anxiety levels, fortunately, this can be relieved by profound rest.
According to a paper published in Nature Human Behaviour, researchers say anxiety can be easily cured with deep sleep.
In a 20 year research, they have found that people with good and normal sleep are free from mental disorders.
“In the past 20 years of research, we have not found a single psychiatric disorder in which sleep is normal,” said Matthew Walker, PhD, professor of neuroscience and psychology at University of California, Berkeley, and Eti Ben Simon, PhD, a postdoctoral fellow in the Center for Human Sleep Science at University of California, Berkeley, told Healio Psychiatry .
The research also found that more than 80% of patients with anxiety have a problem with sleep.
Long working hours, late-night sleep, night shift jobs, not having healthy dinner contributes to lack of sleep which in turns leads to anxiety.
“Anxiety is no exception. Nearly 80% of anxiety patients complain about their sleep, including not being able to fall asleep or stay asleep. Yet poor sleep is often simply thought of as a symptom of the disorder, not as one of the instigating or maintaining factors of anxiety.”– they said.
Walker, Ben Simon and colleagues conducted serious of experiments and scanned the brains of 18 young adults. They scanned their brains while watching emotional videos after a good night of sleep and sleepness night.
The experiment showed an expected result. When the guys were watching videos after a sleepless night, their medial prefrontal cortex was seen shutdown.
Medial prefrontal cortex is a brain region that regulates anxiety. They also found the brain’s deeper emotional centers to be overactive.
“Our findings point to the importance of sufficient sleep in managing anxiety,” Walker and Ben Simon said.
“That is, if doctors aim to treat the sleep complaints of individuals with anxiety using methods such as cognitive behavioral therapy for insomnia, it may provide a significant clinical benefit and decrease the need for medication.” – said Joe Gramigna
