  2. Decreased Exercise tolerance
  3. Unacclimatized patients may experience more systemic symptoms, but core Temperature remains normal
  • 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
  • Management
  1. Move to shaded or cooler environment
  2. Maintain hydration
