First Aid for heat attack

Heat attack is a condition that occurs when the body fails to regulate its own temperature. Under such circumstances the body temperature continues to rise, often to 105°F (40.6°C) or higher. It is the most severe of all heat-related illness and could be life – threatening.


The common symptoms of heat stroke are:

  • A rectal temperature of over 104°F (40°C) after exposure to a hot environment.
  • Head ache
  • Dizziness
  • Confusion
  • Disorientation
  • Fatigue
  • Skin that may be red, hot, and dry, even in the armpits.
  • Signs of moderate to severe difficulty in breathing.
  • Fast heart rate.
  • Sweating that may be heavy or may have stopped.
  • Fluctuating blood pressure
  • Irritability
  • Confusion, severe restlessness, or anxiety.
  • Lack of consciousness / coma for longer than a few seconds
  • Severe vomiting and diarrhea.

Risk Factor

Usually young children, older adults, people who are obese and people born without the ability to sweat are at high risk of heatstroke. These people show the fastest progression of symptoms and can collapse suddenly. Moreover people who are outdoors on a hot, humid day or inside in a poorly ventilated area are also susceptible to heatstroke. The other risk factors include dehydration, alcohol use, cardiovascular disease and certain medications.

First Aid and emergency treatment

1.First move the person into a cool place, out of direct sunlight.

2.Remove the unnecessary clothing of the patient and place the person on his or her side to expose as much skin surface to the air as possible.

3.Sponge the person's entire body to cool it.

4.You can also spray cool-not cold-water, and fan the person to lower the body temperature.

5.Apply ice packs to the groin, neck, and armpits.

6.Check the person's rectal temperature frequently. Try to keep it to 102°F (39°C) or lower. However, it should be kept in mind that temperatures taken by mouth or in the ear are not accurate in this emergency situation.

7.If a child suffering from heat stroke stop breathing, begin rescue breathing.

8.Give the person 1 to 2 liters (32 fl oz to 64 fl oz) over a period of 1 to 2 hours for hydration. However, during this time most people have an altered level of consciousness. For this reason help the person to sit up and drink the fluid to avoid choking.
