After the weather turns hot, I always retch and eat, especially in summer, and sometimes I retch when I breathe.

This situation is often called bitter summer. Bitter summer refers to the phenomenon that after entering the summer, due to the rising temperature, the appetite decreases, the food intake is significantly reduced compared with other seasons, accompanied by low fever (body temperature fluctuates between 37℃ and 37.4℃), physical fatigue, low work efficiency and weight loss. In fact, bitter summer is not a disease, but severe patients can take vitamin C and vitamin B under the guidance of doctors to help regulate autonomic nervous function and eliminate the symptoms of bitter summer. Therefore, eating more fruits and vegetables can spend a bitter summer.
