The best way to survive the heat of a volcano in Zelda is to equip yourself with the Flamebreaker Armor set. This armor set will protect you from the extreme heat of the volcano and allow you to explore the area safely. Additionally, you can use the Ice Rod to create a temporary shield of ice around yourself, which will also protect you from the heat.
Well, you can make a fireproof elixir to survive, or, like the bot said, you can get the armor set.
