Hot drinks like Tea and Coffee would add a small amount of body heat, and restore thirst
Juices and other drinks would restore thirst
Ice cream and other cold foods would remove a small amount of body heat
Two new items: Hot Water Bottle, and Cold Water Bottle. Hot Water Bottles would be made by heating water bottles of any type (filtered water would turn into Hot Clean Water Bottles), and Cold Water Bottles would be crafted with a Water Bottle and an Ice Cube or Snowball.
Having a Hot/Cold water bottle in your hotbar would slowly heat/cool you.
Hot/Cold water bottles would have a durability bar that would slowly go down (at different rates in situations with different temperatures), and when they reached 0 durability, they would become normal Water Bottles.
These could be made with Dirty/Filtered/Clean water.
