What is a critical consequence of hypothermia as it progresses toward lower temperatures?

As hypothermia progresses toward lower temperatures, one of the critical consequences is the potential loss of consciousness and a slow heart rate. As the body temperature falls, the body's metabolic processes begin to slow down significantly. This can lead to confusion, lethargy, and a diminished level of consciousness, as the brain is affected by the drop in temperature. Additionally, the heart rate typically decreases due to the body's efforts to conserve energy and maintain core temperature, resulting in bradycardia, or an abnormally slow heart rate. These symptoms are serious and indicate that the body is struggling to function effectively, requiring immediate medical intervention to prevent further deterioration.
