Children will succumb to heat before adults will.
Symptoms of heatstroke according to the Mayo Clinic.
High body temperature. (click here) A core body temperature of 104 F (40 C) or higher, obtained with a rectal thermometer, is the main sign of heatstroke.
Higher body temperature leading to heatstroke is not due to infection. It is literally the body heating and unable to cool down. The outside temperature is acting on the body and making it warmer. There is no second guessing this. No matter the cause if a person's body temperature is rising and is exposed to excessively hot temperatures they need to be transported immediately to the Emergency Room. Let the doctors sort it out.
Altered mental state or behavior. Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke.
Alteration in sweating. In heatstroke brought on by hot weather, your skin will feel hot and dry to the touch. However, in heatstroke brought on by strenuous exercise, your skin may feel dry or slightly moist.
Nausea and vomiting. You may feel sick to your stomach or vomit.
Flushed skin. Your skin may turn red as your body temperature increases.
Rapid breathing. Your breathing may become rapid and shallow.
Racing heart rate. Your pulse may significantly increase because heat stress places a tremendous burden on your heart to help cool your body.
Headache. Your head may throb.
