Heating
Different blocks and mechanics can help heat up the players surroundings.
A torch held in the off hand or the active slot will raise the temperature slightly. Standing beside a lit firepit, forge or bloomery will warm the player up and raise their body temperature for a time even after stepping away from the heat source. Burning wood or coal piles will have the same effect.
Note that only the firepit will be able to "heat up a room", as the firepit's warming range will be larger while in an enclosed room - other heat sources, or an open air firepit, will only heat up the area in very close proximity to them.
