Cold exposure weariness is the slow grind of prolonged cold exposure — the unprotected sentry on a winter watch, the wet traveler in a long rain, the unsheltered camper in a hard frost. The body burns reserves to maintain warmth, and the burn shows up as weariness rather than as the privation of true freezing. 5–10 fatigue per four hours of exposure.
Symptoms
Mild persistent shivering, cold fingers and toes despite movement, slow stiffness in the joints, dulled appetite, faint clumsiness, occasional teeth-chatter, persistent urge to seek shelter and a fire.
Progression
Sustained chilling without warmth crosses eventually into hypothermia — the body’s compensation fails, shivering becomes violent, then stops, and the privation cycle begins. The transition can be slow or sudden depending on wet, wind, and exhaustion.
Treatment
- Move to shelter — even a windbreak helps
- Dry clothing if any is wet
- Warmth from fire, blankets, or shared body heat
- Hot or warm drink; light food for fuel
Recovery
Four hours of rest reduces weariness fatigue by 5; eight hours of sleep reduces it by 15.
