After reading heat and cold, I started thinking about people who participate in the polar bear plunge. Everyone feels temperatures differently, some people get cold easily and others are always hot- heat and cold are definitely subjective experiences. This is shown in the polar bear plunge, where participants enter a cold body of water in the middle of the winter as they raise money for charity. This is something I’ve always wanted to do, but it’s scary because you don’t know how your body is going to react. Some people do this every year and stay healthy, and there are even tips online for helping your body react after the plunge. However, many people suffer from hypothermia after the polar bear plunge, it sends their bodies into shock and some can’t even swim to safety because of this shock. This is an extreme example, but it’s crazy how differently everyone reacts to the shock of the cold water; and the reading made me realize how, even on a smaller level, heat and cold really are subjective experiences.
