Heat stroke results in hot, dry skin primarily because sweat production is impaired.

Explanation:
When the body overheats, the cooling system relies mainly on sweating and evaporation. In heat stroke, thermoregulation fails and sweat production is impaired, so little moisture reaches the skin to evaporate. Without evaporation, heat cannot be effectively dissipated, causing the core temperature to rise while the skin feels hot and dry. This dry skin is a classic sign that the sweating mechanism has broken down, distinguishing heat stroke from conditions where the skin remains moist due to ongoing sweating.
