First aid for sunstroke

If you come across a person who had experienced sunstroke then you can immediately apply some first aid. This is what you should do:

  • First call emergency service immediately for help or take him/her immediately to a hospital
  • In the meantime move the person to some shady place or in an air conditioned cool environment.
  • Apply water to his face, pour on the body and try to cool his body by blowing air or any other possible way that’s in handy
  • If the person is at home than apply ice pack around armpits, back, neck and groin or bathe him/her in cold water
  • Loosen the clothing, make sure there’s enough ventilation and drink cold water to restore hydration

Medical diagnosis and treatment for sunstroke

Once the victim reaches hospital, he/she will be under medical observation. The doctor will feel the pulse or measure the heart rate and take readings of the temperature.

Paracetamol and aspirin like drugs are not prescribed to bring down temperature, rather it is managed through cooling therapies. The hospital treatment options are similar to first aid but are done under extreme care.

  • The patient is immersed in a bath filled with ice and water.
  • The patient is covered with cooling blankets with application of ice pack in groin, neck, back and armpit.
  • Evaporation cooling is done wherein the individual’s body is sprayed with a mist of cool water accompanied by a fan which enhances the rate of evaporation of heat from the body.

If the individual has fainted then he/she would be taken to recovery room. The patient might be retained in hospital for further stabilization and for undergoing organ function tests if any complication has been suspected by the doctor.

How to prevent sunstroke

  • Avoid taking your little on e out for sun basking, for that matter avoid it if you are old. Limit outdoor activities during day time.
  • Drink plenty of water, juices and watery fruits. Cut down beverages, alcohol and caffeine
  • Use a sun block of SPF 30 or more before stepping out under sun
  • Use umbrellas, hats or head gear and wear light loose cotton clothing
