At what core body temperature does heatstroke begin to occur?

Heatstroke is a severe health condition that occurs when the body's temperature regulation fails, leading to an elevated core body temperature that can cause serious damage to vital organs. Heatstroke typically begins to occur at a core body temperature of 104 degrees Fahrenheit. At this temperature, the body's normal cooling mechanisms, such as sweating, become ineffective, and the risk of cellular damage, organ failure, and other life-threatening complications significantly increases. This temperature threshold is critical for recognizing the onset of heat-related illnesses, allowing for timely intervention to prevent more severe consequences. Maintaining awareness of this core temperature is important for anyone working in hot environments or engaging in strenuous activities during heat waves.
