Cold Sweat
by Mikul
Cold Sweat is a temperature mod for Forge and NeoForge that makes heat and cold part of survival, with the world, the player's gear and the weather all affecting body temperature.
What it does
Body temperature in Cold Sweat responds to biomes, nearby blocks, held or worn items, weather and altitude. Players can insulate armor against the elements, stay beside blocks that warm or cool them, and use waterskins for quick relief or as portable cooling and heating packs. A thermometer displays the current temperature with precision, so the player can see where their values stand before a trip.
The mod draws each biome's temperature from the vanilla biome property, so modded biomes are handled too, as long as their temperatures are set correctly. Configuration is available both in game and through files, which lets a server owner tune how harsh the system is. Cold Sweat is open source under the GNU General Public License v3.0 or later, and its source code, issue tracker and wiki are public.
Installation requires the mod on the client and on the server, because the environment is client and server. Cold Sweat is published for Forge and NeoForge across nine release versions, 1.16.5 – 1.21.1, with the newest Forge file for 1.20.1 and the newest NeoForge file for 1.21.1.

Use cases
Survival hardcore runs
Players who want the world to punish careless travel can rely on the temperature system to make exploration risky.
Modded biome packs
Packs with many added biomes can keep temperature logic consistent, because the mod reads the vanilla biome property.
Who it’s for: Survival players who want temperature to matter, and server owners who want a configurable survival layer that runs on both sides.
