New armors and mechanic's

Hello, I've been thinking that, since it was added the frozen to minecraft it could be added too the overheat. It could appear in the hottest biomes and it could make the player have thirst and make us see a mirage, it could be solved with a water bottle, giving it more uses, or a tunic that cover us from the sun, it only would work in the overworld and it's craft would be with carpets or wool, and in the coldest biomes an armor of leather and wool, the fluffy armor, gives more resistance to cold but less to damage.

(Truly sorry by the bad grammar, I'm not used yet to english)
