What signs indicate heat stroke requiring urgent medical care?

• A. No sweating
• B. Very high body temperature, confusion or seizures, red and dry skin, no sweating, faintness
• C. Cold and clammy skin with sweating
• D. Mild dizziness

Answer: (B)

Heat stroke is a medical emergency—the body's cooling system stops working and the brain is affected. The signs that require urgent medical care include an extremely high body temperature combined with altered mental status (confusion or seizures) and hot, red, dry skin. The absence of sweating is also a warning sign that cooling has failed. This combination signals that the body's core temperature is critically high and damage can occur quickly, so immediate medical help is essential. If you encounter this, call emergency services and start cooling the person while waiting for help. Other heat-related problems tend to show different patterns, like heavy sweating with cool, moist skin in heat exhaustion, or only mild symptoms like dizziness, which do not indicate the same emergency.
