Final answer:
Heat stroke is a serious heat-related illness that requires immediate medical attention due to the body's inability to regulate temperature effectively.
Explanation:
Heat stroke is a severe heat-related illness where the body's temperature rises above 105°F, causing the brain's temperature-regulatory center to shut down. This leads to symptoms like dry skin, extreme confusion, and unconsciousness, requiring immediate medical attention. Dehydration is a primary cause of heat stroke as it impairs the body's ability to cool itself.
