If insomnia occurs occasionally and one night without sleep, it usually does not matter. If it occurs repeatedly, it is important to find the cause for treatment. Prolonged insomnia may cause a decrease in immune function, which can cause patients to develop organic diseases, or it may cause cognitive dysfunction, memory function decline, etc. Insomnia can occur for a variety of reasons, such as excessive mental tension and stress during the day, which may lead to insomnia at night. Insomnia can occur if the patient has neurasthenia and can also occur when there is anxiety or depression. Insomnia may also occur if the patient enters menopause, for example, at the age of 45-55, due to a decline in estrogen production. Treat the cause accordingly for different reasons.
