Pro Tip
Distinguishing 熱射病 from 熱中症
While 熱射病 specifically refers to heatstroke caused by direct heat exposure (e.g., sunlight), 熱中症 is a broader term covering heat-related illnesses, including dehydration and heat exhaustion. In practice, both terms are often used synonymously in everyday speech.
Gold Rule
Medical Urgency
If someone shows signs of 熱射病 (e.g., high body temperature, confusion, or unconsciousness), call emergency services immediately and move them to a cool place.
Word Origin
熱 (heat) + 射 (strike/attack) + 病 (illness/disease). The term describes a condition where heat 'attacks' the body, leading to severe illness.
Usage Notes
In modern Japanese, 熱射病 is often used interchangeably with 熱中症 (heatstroke/sunstroke), though 熱中症 is the more commonly used term in general contexts. 熱射病 emphasizes the direct impact of heat radiation or intense sunlight.
