This episode explores survival in the mountains, an environment as dangerous as it is beautiful. The first major challenge is altitude, where thinner air reduces oxygen and can cause altitude sickness if you ascend too quickly. Survivors must climb gradually, rest, hydrate, and listen to their bodies. The terrain itself presents constant risks: falls, rockslides, avalanches, and hidden crevasses. Moving slowly, testing each step, and using ropes or trekking poles can reduce danger. Weather is another unpredictable threat. Sudden storms, lightning, or freezing winds can strike without warning, so layering clothes, preparing shelters, and avoiding exposed ridges are critical.
