Temperature

Temperature is an important mechanism in One Hour One Life, which can mean life or death. Your current temperature is indicated by a small arrow on your temperature gauge. As a general rule you want to aim to have your warmth indicator arrow to be pointing at the middle line. Your body temperature gradually moves toward the environment temperature over time, which is influenced by clothes, biome, heat sources such as fire and buildings.

Being closer to optimal temperature will slow your food meter consumption, while being further from optimal temperature will speed it. For example if you are naked in the tundra, or fully geared in the desert whilst standing on a fire, either way you will starve to death very quickly.

Yellow Fever, which is acquired from a Mosquito Swarm can also raise your temperature.

Clothing
Different items of clothing transfer different percentages of insulation (available on the clothes page). Being naked will lower your temperature gauge, while wearing warm clothes in a hot environment can cause overheating.

Biomes
The tundra is a particularly cold environment. While desert is a particularly hot environment. It is common to start villages in warm biomes to lower food consumption.

Insulating Structures
Certain structures can help contain heat in an area by insulating tiles, much like clothes.

Info

 * v148 Temperature mechanism updated; "the "just keep running" exploit to lock your temperature no longer works. and your temperature will no longer jump around suddenly and unexpectedly when you step next to a fire. [...] Furthermore, temperature updates happen whether or not you are moving (every two seconds). This also means that if the fire goes out next to you, but you don't move, your temperature will eventually go down to reflect the new, cooler environment around you." -Jason Rohrer
