II. Pathophysiology

  1. Body response to excessive heat load
  2. Heat Stroke is the most mild form on continuum to Heat Exhaustion and Heat Stroke

III. Symptoms

  1. Heat-related discomfort
  2. Decreased Exercise tolerance
  3. Unacclimatized patients may experience more systemic symptoms, but core Temperature remains normal

IV. Signs

  1. Core Temperature unchanged (<38 C or 100.4 F)
  2. Contrast with Heat Exhaustion where core Temperature rises above 38 C (100.4 F) associated with systemic symptoms
  3. Contrast with Heat Stroke where core Temperature rises above 40 C (104 F), asssociated with altered consciousness

V. Management

  1. Move to shaded or cooler environment
  2. Maintain hydration
