Not feeling hot even when wearing several sweaters during the daytime at twenty-five degrees Celsius has something to do with each person’s body sensation; it may also have something to do with the humidity of the surrounding environment. In addition, if the perception of heat is different from that of most of the people around you in the same environment, it is recommended to go to a regular hospital for examination to clarify the cause of the disease and then treat the cause. 1. Everyone perceives heat differently, so some people don’t feel hot even if they wear more clothes at the same temperature, which is a normal phenomenon and can be interfered with without needing to do so as long as there is no uncomfortable feeling. 2. The environment will also have an impact on the human body feel: for example, in winter, the air humidity is low, will not feel too hot; summer air humidity is greater, the same temperature will feel very hot. So in winter, even if it’s in the twenties, you won’t feel hot in a sweater. In the same environment, if the perception of heat is different from most of the people around, it is recommended to go to a regular hospital for examination, and after the cause is clarified in a timely manner, treat the cause.
