During the epidemic, people's routine was changed, with a delay of 2-3 hours compared to the regular period. Also, people ate more late night snacks than during the regular period, which led to insomnia and reduced sleep quality.

From a social perspective, the epidemic has had a significant impact on life, such as increased unemployment, rising prices, and prolonged isolation, which can cause people to become depressed and frustrated, which can lead to insomnia as people are unable to concentrate when they fall asleep.

Approximately 50% of insomnia cases are associated with depression, anxiety, or psychological stress. While insomnia can be a symptom of mental illnesses such as anxiety and depression, it is now recognized that sleep problems can also lead to the onset and worsening of different mental health problems, including depression, anxiety, and even suicidal ideation. Insomnia and anxiety are seen to influence each other, and this cycle appears stronger during the epidemic, so more people lose sleep.

From a psychological analysis, symptoms such as anxiety are the main cause of insomnia during the epidemic, so I will focus on how to relieve people's anxiety to treat insomnia.
