What is a common risk of rapid cooling during rehab after heavy exertion?

• A. Hyperthermia risk.
• B. Hypothermia risk if not properly managed, plus potential shivering increasing metabolic demand.
• C. Cardiac arrest due to heat.
• D. Dehydration only.

Answer: (B)

Cooling too quickly after heavy exertion can drop the body’s temperature faster than the body can safely manage, creating a real risk of hypothermia. When the core or skin temperature falls, the body may respond with shivering to generate heat. Shivering greatly raises metabolic rate and oxygen consumption, increasing the heart and lungs’ workload right when someone is recovering from strenuous work. That combination—rapid cooling leading to potential hypothermia plus shivering-driven metabolic demand—is the core risk here. Hyperthermia or heat-related issues would be concerns during or after excessive heat exposure, not from rapid cooling, and dehydration is a separate factor that isn’t the direct result of cooling itself.
