Hypothermia

Hypothermia is a thermal affliction that affects Duplicants when they spend too long in cold environments. It reduces a Duplicant’s effectiveness across several core skills and also makes them sneeze more often, which can complicate colony management when a base is chronically freezing.

When active, Hypothermia applies -5 Science, -5 Machinery, -5 Cuisine, and -5 Construction, along with +1 Sneeziness. Its duration is 180 seconds, or 0.3 cycles. Because it is tied to exposure to cold, the best treatment is prevention through temperature control and appropriate clothing.

• Warm Sweaters provide some relief for a colony that is constantly running cold.
• Warm Coats provide the same kind of help and are a practical way to blunt the effect of low temperatures.
• Atmo Suits and Jet Suits almost completely prevent thermal-related afflictions, making them the strongest protection against Hypothermia.
• There is a likely bug where Duplicants can re-catch Hypothermia after loading a save if they were still cold when the game was saved.

Keeping Duplicants out of frigid biomes, insulating work areas, and giving them cold-weather clothing all reduce the chance of repeated outbreaks. Because the affliction penalizes both science and construction-related tasks, it can slow down base expansion and other critical projects if a colony is not prepared for low temperatures.
