Insomnia caused by seasonal climate change is more common in spring. If so, don't worry, do more exercise, relax while sleeping, and you can also eat some Chinese patent medicines such as "Schisandra syrup".
2. Insomnia caused by age is generally the cause of calcium deficiency. Then strengthen exercise and drink a cup of 300-400 ml of warm milk before going to bed.
3. Insomnia caused by work pressure or other important things. It is best to make self-psychological adjustment, strengthen exercise, and resort to drugs if there are difficulties. But it can only play a temporary relief role, and long-term use will bring side effects. Care should be taken to avoid drug dependence.
If the above can't be solved, you'd better see a doctor. Still believe in science.
In short, the most important thing to solve insomnia is to strengthen physical exercise. Exercise, disease does not appear.
I wish you health and happiness!
