Insomnia Often Related to Stress

New research identifies a link between the way people cope with stress and the development of insomnia.

Saliently, researchers discovered many of the normal methods to cope with stress are linked to insomnia, a finding that suggests emerging therapeutic interventions such as mindfulness meditation, or cognitive behavioral therapy may be better options.

In the study, investigators learned that coping with a stressful event through behavioral disengagement — that is, giving up on dealing with the stress — or by using alcohol or drugs each significantly increases the risk of insomnia.

Unexpectedly, researchers found that even the coping technique of self-distraction — such as going to the movies or watching TV — also was a significant factor between stress and insomnia.

Furthermore, the study found that recurrent thoughts about the stressor (cognitive intrusion) — was a significant factor, accounting for 69 percent of the total effect of stress exposure on insomnia.

“Our study is among the first to show that it’s not the number of stressors, but your reaction to them that determines the likelihood of experiencing insomnia,” said lead author Vivek Pillai, Ph.D.

“While a stressful event can lead to a bad night of sleep, it’s what you do in response to stress that can be the difference between a few bad nights and chronic insomnia.”

The study, as published in the journal Sleep, involved a community-based sample of 2,892 good sleepers with no lifetime history of insomnia.

At baseline the participants reported the number of stressful life events that they had experienced in the past year, such as a divorce, serious illness, major financial problem, or the death of a spouse. They also reported the perceived severity and duration of each stressful event.

Questionnaires also measured levels of cognitive intrusion and identified coping strategies in which participants engaged in the seven days following the stressful event.

A follow-up assessment after one year identified participants with insomnia disorder, which was defined as having symptoms of insomnia occurring at least three nights per week for a duration of one month or longer with associated daytime impairment or distress.

“This study is an important reminder that stressful events and other major life changes often cause insomnia,” said American Academy of Sleep Medicine President Dr. Timothy Morgenthaler.

“If you are feeling overwhelmed by events in your life, talk to you doctor about strategies to reduce your stress level and improve your sleep.”

According to the authors, the study identified potential targets for therapeutic interventions to improve coping responses to stress and reduce the risk of insomnia.

In particular, they noted that mindfulness-based therapies have shown considerable promise in suppressing cognitive intrusion and improving sleep.

“Though we may not be able to control external events, we can reduce their burden by staying away from certain maladaptive behaviors,” said Pillai.

The American Academy of Sleep Medicine reports that short-term insomnia disorder lasting less than three months occurs in 15 to 20 percent of adults and is more prevalent in women than in men.
