Key Factor That May Lead to Depression Identified
Experts say everyone may experience symptoms of depression at some point in life due to sadness or trauma.
LAHORE, (Pakistan Point News - 13th Nov, 2026) Depression affects not only a person’s emotions and mental health but also the body. It is a complex mental illness whose symptoms can include persistent sadness and feelings of helplessness. Experts have yet to determine why people develop the condition, but a new study has identified the absence of a regular sleep routine as a possible contributing factor.
Research by the University of California in the United States found that irregular sleep, or having no sleep schedule, can have significant negative effects on mental health. People who do not go to sleep and wake up at set times each night and morning were more likely to experience serious symptoms of anxiety, depression, and loneliness.
The study analyzed data from more than 23,000 people, collected through wearable trackers during the COVID-19 pandemic. Researchers had an average of 154 days of data for each participant and examined their sleep and waking patterns. Monthly surveys also gathered information about participants’ depression, anxiety, and loneliness.
The findings showed an association between sleep patterns and mental health problems. According to the study, people whose bedtimes and waking times vary can also experience negative effects on their mood.
Researchers stated that an irregular sleep schedule can affect daily routines, including meal and exercise times, social activities, and other habits. These factors can negatively impact the body’s internal clock, while a consistent sleep and waking routine helps keep it functioning properly.
They emphasized the need for further study but concluded that maintaining a consistent sleep schedule is crucial for mental health. The findings were published in the journal Scientific Reports.
