A person is more vulnerable to stress amid lack of sleep, said researchers at the University of California, Berkeley.

According to Science Daily, scientists performed functional magnetic resonance imaging of the brain of 18 young people who watched emotionally exciting video clips after a sleepless night and after a full sleep. Anxiety levels were evaluated using questionnaires, and sleep quality was determined on the basis of indications obtained using polysomnography.

As it turned out, lack of sleep reduced activity in the medial prefrontal cortex, which helps control anxiety, while the deeper emotional centers of the brain were overexcited. And the level of anxiety decreased significantly after a full sleep with a deep phase.
