A four-panel image shows a woman progressing through stages of hypothermia in a cold lake, from shivering to unconsciousness.

A highly realistic medical training scene set at a cold lakeside in daylight, showing the same adult woman depicted four times in one image, each representation illustrating a different stage of hypothermia progression after ice swimming. The environment is natural, with a calm lake, cold air, and soft daylight — not dark or overly dramatic. On the left side, Stage 1 (mild hypothermia, excitation stage): the woman is conscious and alert, wearing a wet swimsuit and a knitted beanie, visibly shivering intensely, hugging herself for warmth. Her skin is pale, her posture tense, with rapid breathing and signs of distress from the cold. Next, Stage 2 (moderate hypothermia, exhaustion stage): the same woman appears confused and apathetic, her movements uncoordinated, shivering reduced or stopping. Her skin is pale to slightly bluish, posture slumped, with a distant, unfocused gaze. Subtle signs of paradoxical undressing may be suggested (e.g., loosened clothing or towel slipping off). Next, Stage 3 (severe hypothermia, paralysis stage): the woman is unconscious, lying or slumped on the ground near the lakeshore. Her body appears rigid, her face expressionless, with very pale or bluish skin. Her breathing is barely noticeable, and her posture shows complete loss of muscle control. On the right side, Stage 4 (critical hypothermia, life-threatening stage): the same woman lies motionless, deeply unconscious, with no visible movement. Her skin appears greyish-blue, and her body is limp. Mehr sehen
