Light sleep is not equal to no sleep, just poor sleep quality. Human sleep consists of alternating light sleep and deep sleep, and deep sleep occupies about 25% of the whole sleep time. Through deep sleep, people can get rest and tissue repair, while if there is too much light sleep and cannot enter into deep sleep, they will feel especially tired of sleeping, and the next day may have weakness, dizziness, lack of concentration, mood change, etc. They feel that sleeping is not relieved, and they feel the same as not sleeping. In addition, patients with light sleep are also more prone to dreaming. If patients feel that it affects their working life the next day, they can go to the neurology department of the hospital and be treated by oral medication or acupuncture. For factors affecting sleep quality such as snoring, drinking, staying up late, and work stress, you can make targeted corrections on your own to develop good sleep habits and improve sleep quality.
