Heat stroke

Heat stroke, also known as sun stroke, is a severe heat illness, defined as hyperthermia with a body temperature greater than 40.6 °C (105.1 °F) because of environmental heat exposure with lack of thermoregulation. This is distinct from a fever, where there is a physiological increase in the temperature set point of the body. The term "stroke" in "heat stroke" is a misnomer in that it does not involve a blockage or hemorrhage of blood flow to the brain. Preventive measures include drinking plenty of cool liquids and avoiding excessive heat and humidity, especially in unventilated spaces such as parked cars that can overheat quickly. Treatment requires rapid physical cooling of the body.

Signs and symptoms

Heat stroke generally presents with a hyperthermia of greater than 40.6 °C (105.1 °F) in combination with disorientation and a lack of sweating. Before a heat stroke occurs people show signs of heat exhaustion such as dizziness, mental confusion, headaches, and weakness. However, if a heat stroke occurs when the person is asleep symptoms may be harder to notice. However, in exertional heat stroke, the affected person may sweat excessively. Young children, in particular, may have seizures. Eventually, unconsciousness, organ failure, and death will result.

Heat illness

Heat illness or heat-related illness is a spectrum of disorders due to environmental exposure to heat. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke.

Classification

A number of heat illnesses exist including:

  • Heat stroke - Defined by a body temperature of greater than 40 °C (104 °F) due to environmental heat exposure with lack of thermoregulation. Symptoms include dry skin, rapid, strong pulse and dizziness.
  • Heat exhaustion - Can be a precursor of heatstroke; the symptoms include heavy sweating, rapid breathing and a fast, weak pulse.
  • Heat syncope - Fainting as a result of overheating.
  • Heat edema
  • Heat cramps - Muscle pains that happen during heavy exercise in hot weather.
  • Heat rash - Skin irritation from excessive sweating.

    Look like hell, smell real bad
    Rotting teeth, give me drugs
    Frothing mouth, fiend for more
    Chaos rules, give me drugs
    At night I lay down next to you
    After you fall asleep I'll steal from you
    Get ready to receive the destroyer
    At night I lay down next to you
    After you fall asleep I'll steal from you
    All the heinous things you would do
    They'll all catch you and they will thrash you
    Got no cash, got no sense
    Bleeding gums, give me drugs
    I'm a snake, snake of hate
    And I hiss, and I bite
    At night I lay down next to you
    After you fall asleep I'll steal from you
    Get ready to receive the destroyer
