Our bodies are able to compensate for extreme cold a lot better than extreme heat, so it's important to recognize that we are going to increasingly need effienct heat management systems that prioritize removing heat in an efficient and scalable way rather than focusing on adding heat. As you say, we can make up the difference ourselves usually by just adding insulating layers to retain core heat.
