Which statement about heat stress is true?

• A. Less than 10 percent of people affected by severe heat stroke die
• B. Lack of sweat is a symptom of heat stroke
• C. Wearing lots of PPE prevents heat stress
• D. None of the above

Answer: (B)

Heat stress happens when the body’s cooling system can’t keep up, and heat stroke is the extreme state where temperature regulation fails and core temperature rises rapidly. A key sign you’ll often see with heat stroke is lack of sweating—the body’s sweat production stops, leaving the skin hot and dry. This absence of sweating indicates the body is no longer able to cool itself effectively, which is why it’s a critical warning sign and why the statement is true. Wearing lots of PPE might seem protective, but it actually traps heat and usually makes heat stress worse rather than preventing it, so that isn’t correct. And since lack of sweating can occur in heat stroke, the option claiming none of the above isn’t correct either.
