Loss of manual dexterity is a symptom of cold stress.

Explanation:
Cold stress impairs fine motor control because the body narrows blood vessels in the extremities to conserve heat, reducing blood flow to the hands. This makes fingers numb and stiff, slows nerve signaling, and weakens muscle performance. As a result, precision tasks—like gripping, manipulating small parts, or tying knots—become harder. Shivering and tremors can further disrupt control, worsening dexterity. These effects occur with cold exposure, not in hot environments, so loss of manual dexterity is indeed a symptom of cold stress.
