Irregular sleep linked to depression and anxiety

The habit of going to bed and waking up at different times can be associated with a deterioration in psychological state. American researchers have found that people with unstable sleep patterns are more likely to experience symptoms of depression, increased anxiety and feelings of loneliness. The results are published in the scientific journal Scientific Reports.

Scientists from the University of California studied data of about 23 thousand volunteers with an average age of 46 years. Participants wore smart rings that recorded the time of falling asleep and waking up. On average, each person was followed for 154 days, and their psychological state was assessed using monthly surveys.

It turned out that in people without severe signs of depression, the regularity of sleep reached an average of 84 points out of 100. With severe symptoms, the indicator decreased to 75 points. A similar pattern was revealed with anxiety. The stronger its manifestations were, the less constant the rest schedule was.

Experts suggest that frequent changes in sleep time can knock down the internal biological clock and affect everyday habits. However, the study does not prove that irregular sleep causes psychological problems. Communication can work both ways. Emotional difficulties can also disrupt the usual mode of rest.

Scientists have found that a popular supplement can lower blood pressure.
