Turning Night Long: Sleep Deprivation enjoys a key role in enhancing anxiety, a new study suggests |
Researchers at University of California-Berkeley observed the
anxiety levels of 18 young and healthy adults. Anxiety test in the morning after a deep sleep night and a sleepless night respectively, revealed that after sleep deficient
night, anxiety levels were 30% higher compared to anxiety levels after proper
night rest. The anxiety scores on average, almost touched the levels possessed by
person with ‘anxiety disorder’, concluded researchers Mathew Walker and Ben
Simon.
Loss of sleep activates amygdala and insular cortex – regions
of human brain handling emotions and fight or flight response, disabling
prefrontal cortex – part of brain that lowers anxiety, functional MRI scan
showed.
Walker says, “As the study discloses, if the sleep
deprivation is factor responsible for anxiety, then it’s surely a treatable objective”.
Chronic Worriers are more vulnerable to effects of sleep deficiency |
People with anxiety disorder find harder to sleep, but this
new study put forward the reverse relationship of anxiety and sleeplessness. “It’s
a two-way interaction, shows this study. Sleep loss induces anxiety which in turn
makes it difficult to fall asleep”, speaks sleep researcher Clifford Saper at Berth
Israel Deaconess Medical Center and Harvard Medical School, Boston who was uninvolved in the study.
Those who are worrywarts or chronic worriers – people who are naturally anxious which can lead them towards anxiety disorder – are more vulnerable to effects of
sleeplessness, researchers believes.
“This study exemplifies the importance of sleep to our mental
health. It also showed us the relationship between psychiatric disorders and sleep,
in sense of both treatment and cause”, says Mathew Walker about the research.
The result states that deprived sleep is ‘more than a symptom of anxiety’, and in some cases it plays a role of cause, said Ben Simon.
