The weather is dry, and the temperature fluctuates between cold and hot, so people are easily susceptible to catching a cold. In fact, regardless of any disease, it is always the result of interaction between the body's immune system and pathogenic factors. If the body's resistance is stronger than the effect of pathogenic factors, the body will be very healthy; otherwise, it will get sick. Colds are even more so. People who are overly tired, lack sleep, have a bad mood, suffer from some chronic diseases, or are physically weak are more likely to catch a cold. Therefore, if you want to avoid being bothered by colds or enhance your ability to fight against them, dietary adjustments must be put on the "agenda".
