Emotion can cure or cause diseases. Psychologists have found that people's skin will be flushed and hot when they are excited, and pale and cold when they are nervous or angry. If people's mood changes dramatically, it will also lead to skin allergies and even affect hair. At the same time, the correct emotions such as happiness and joy can also accelerate the healing of wounds and promote the healing of diseases.
