New York, February 18: Getting fewer hours of sleep or staying up late most nights can increase the risk of depression, a new study suggests. The findings, published in the journal npj Digital Medicine, indicates that an irregular sleep schedule can increase a person's risk of depression over the long term.

"The work also underscores the potential of wearable devices in understanding important constructs relevant to health that we previously could not study at scale," Sen added. How to Sleep Better at Night Naturally? From Proper Diet to Physical Exercise, Best Tips for Quality Sleep.
For the study, the team used data from direct measurements of the sleep and mood of more than 2,100 early-career physicians over one year. The study is based on data gathered by tracking the participants' sleep and other activity through commercial devices worn on their wrists and asking them to report their daily mood on a smartphone app and take quarterly tests for signs of depression.
Those whose devices showed they had variable sleep schedules were more likely to score higher on standardized depression symptom questionnaires, and to have lower daily mood ratings, the researchers said.
Those who regularly stayed up late, or got the fewest hours of sleep, also scored higher on depression symptoms and lower on daily mood, they added. "The advanced wearable technology allows us to study the behavioural and physiological factors of mental health, including sleep, at a much larger scale and more accurately than before, opening up an exciting field for us to explore," said researcher Yu Fang from the varsity.
