When the weather is hot in summer, I feel flustered, dizzy, nauseous, weak all over, and easy to catch a cold. What is the reason? What should we do?

First of all, exercise, drink more sugar water or salt water when it is hot, not cold; Drink warm. Secondly, go to bed early and get up early. Don't stay up late if you have chronic urticaria. Girls just need to go to bed early, eat more pears and drink more water to relieve the heat. Mood again, hey hey mood is very important. Don't think too much about some things. The more you think about it, the more problems you have, the more you will enlarge the problem. Just rest assured.
