ELI5: Why are humans most comfortable at room temperature (~22°C) but not at body temperature (37°C)?

Our ideal body temp is 37 degrees. Our bodies are essentially like engines that convert food into energy we can use, and the use of this energy whether it be for muscle contraction or to produce bio molecules in our body produces heat. To prevent our bodies from exceeding our natural body temp radiate this heat into the environment. So at 37 degrees our bodies are still generating heat but cannot release it without sweating etc. Plus we wear clothes which prevent additional heat loss (by trapping the heat we are trying to radiate).
