Heat Exposure

Definition:
Heat exposure refers to the condition of being exposed to high temperatures, particularly in environments with high heat and/or humidity. It doesn’t necessarily result in illness but can lead to heat-related conditions if not managed.

Key Points:

  • Can be mild to moderate.
  • Symptoms might include thirstfatiguesweating, and discomfort.
  • If prolonged or intense, it can progress to heat-related illnesses such as heat crampsheat exhaustion, or heat stroke.
  • Usually reversible with rest, hydration, and cooling.

Heat Stroke

Definition:
Heat stroke is the most severe form of heat-related illness and is a medical emergency. It occurs when the body’s core temperature rises above 104°F (40°C) and the body’s thermoregulatory mechanisms fail.

Key Features:

  • Altered mental status: confusion, disorientation, seizures, or unconsciousness.
  • No sweating in classic cases (especially in elderly or during passive overheating), though exertional heat stroke may still show sweating.
  • Hot, dry skin or profuse sweating depending on the type.
  • Can cause organ failurebrain damage, or death if not treated rapidly.

Treatment: Immediate cooling (e.g., ice packs, immersion in cold water) and emergency medical care.

Summary Table:

SeverityMild to moderateSevere and life-threatening
Core TemperatureUsually normal or slightly high>104°F (40°C)
Mental StatusNormalAltered or unconscious
SweatingPresentMay be absent (classic) or present (exertional)
