Temperature999 Plugin Wiki & Guide

Watch the boss bar at the top of your screen—it shows your current body temperature and changes color as you heat up or cool down. You'll also hear panting sounds if you overheat or a freezing sound if you get too cold, and your movement will slow down when either extreme is reached.

Metal armors like iron and diamond actually let cold in, so they won't protect you in snowy biomes. Switch to leather armor or turtle shells instead, which provide warmth and will keep you safe from freezing damage.

Stand near a heat source like a campfire, furnace, or lava block—these will raise your body temperature quickly. If you're far from any of these, moving to a warmer biome or going indoors during the day will also help.

Walk on ice or snow blocks to drop your temperature, or find shade and wait for nighttime when the world cools down naturally. You can also travel to a colder biome like a taiga or snowy area for immediate relief.
