Prevents death from the frequent jumpscares and "Invisible Zombies" found in areas like the Scientific Module.
The military has known this for decades. The most effective SIT involves unpredictable, uncontrollable stressors. A Cold Fear Trainer replicates the "oh shit" moment of real life. For example, a pilot training for engine failure does not benefit from an instructor saying, "In ten seconds, I will pull throttle one." That is warm. A cold trainer pulls the throttle mid-sentence during a radio call. That single moment of genuine shock is worth fifty rehearsed drills.
When the body is exposed to cold temperatures, it responds by releasing certain neurotransmitters, such as noradrenaline, which play a crucial role in attention, arousal, and stress response. By repeatedly exposing individuals to cold temperatures, "Cold Fear" trainers aim to increase the production of these neurotransmitters, making them more resilient to stress.
