Regular work and rest is the most important thing, besides diet and exercise. It's strange that you're not tired of posting on the Internet after one o'clock. In general, you should go to bed after ten o'clock, not more than eleven thirty. You can add some probiotics, such as Xiancun (60 yuan can eat more than 50 bottles in two months and 30 yuan about one month), Jinshierkang (about 30 bottles in a month) and 2 1 Jinweita (about 25 bottles in a month and about 35 yuan in 50 days). I have been eating Xiancun, and the content is relatively high. I haven't caught a cold for years.
In addition, we should pay attention to diet, eat more foods rich in protein, such as meat and eggs, eat less high-fat things, drink less, don't smoke, and don't eat fried foods such as instant noodles.
There is also proper exercise. Don't get up in the morning to exercise. Generally speaking, it is better to exercise around 6 pm. It should be done step by step. It is advisable to sweat slightly at first, and then gradually increase the amount of exercise according to the situation.
Just stick to it for a while, don't worry too much, and relax.
