### condition | illness | collapse:

Heat exhaustion
* Have the person lie down in a cool place and sponge the body with cold water.
* Most heat exhaustion causes fatigue.
* affects athletes.
* can evolve into heat stroke.
* can lead to dizziness, blurred vision, nausea, and eventual collapse
  - heat stroke, which is life-threatening
  - occur on any fire
* can progress quickly to heat stroke, a potentially fatal condition
  - very quickly to heat stroke
  - quickly lead to heat stroke
  - result in headaches, dizziness, nausea, and possibly chills and confusion
* causes a person to become nauseous and light-headed
  - fatigue, dizziness and disorientation
  - impaired ability, dizziness, headache, vomiting and clammy skin
  - pale, clammy skin, weakness, nausea and heavy sweating
* common response to working in summer weather.
* happens from overexercising, which causes the body to lose fluids
  - when one is exposed to heat for a prolonged period of time
* involves symptoms and signs of fluid and salt loss.
* is caused by excessive exposure to heat and the depletion of body fluids.
* is caused by excessive fluid loss in a hot environment
  - exposure to excessive, moist heat
  - inadequate fluid intake
  - overexposure to high temperatures and humidity
* is caused by the failure to adjust to extended exposure to high heat
  - loss of large amounts of fluid and electrolytes
* is characterized by an increase in core temperature and heart rate
  - extreme weakness or fatigue, dizziness, nausea, and headache
* is characterized by fatigue, nausea, headache, and clammy and moist skin
  - weakness, and even collapse
  - due to dehydration
* is due to more profound loss of water and electrolytes
  - water and electrolyte loss
  - fatigue, sometimes leading to collapse, caused by overexposure to heat
  - heatstroke
* is marked by excessive dehydration and electrolyte depletion
  - fatigue, heavy sweating, dizziness, nausea and fainting
* is more likely after a few days of a heat wave than when one is just beginning
  - serious than heat cramps
  - severe than heat cramps and has several symptoms
  - related to heat stroke, although they are two separate problems
* is the body's response to an excessive loss of water and salt contained in sweat
  - the loss of water and salt from sweating
  - early sign that the body needs to rehydrate
  - most common form of heat illness
* is the next severe form of heat injury
  - step beyond simple dehydration
  - stage before heat stroke where sufferers become weak and sweat heavily
  - warning the body gets that it is getting too hot
* is usually reversible if the body is cooled off right away
  - the result of excessive heat and dehydration
* medical emergency.
* milder condition than heat stroke.
* more severe condition than heat cramps.
* occurs before heat stroke.
* occurs when a dehydrated person continues to exercise
  - children get hot and lose too much fluid through sweating
  - heat stress causes fluid depletion
  - the body is unable to cool itself properly
* occurs when the body loses excessive amounts of water and salt through sweating
  - too much fluid and salt
* serious medical condition.
* starts with weakness, nausea, dizziness and profuse sweating.
* takes time to develop, while heat stroke can strike suddenly
* warning that the body is getting too hot.

Heatstroke
* begins when a person's internal thermostat stops working.
* causes multiple metabolic abnormalities.
* is possible with prolonged exposure and physical activity.
* occurs in two forms, exertional and classic
  - when the body is unable to lose heat
* occurs when the body's central control mechanisms fail
  - thermoregulatory system stops working

Implosion
* has no effect on creatures in gaseous form or on incorporeal creatures.
* key point in the science of revitalizing of water, or the erasing of information.
