Health and advice

Summer and high temperatures significantly increase the risk of heat stroke. Knowing what it is, how to identify it and how to act quickly can make the difference between a scare and a serious medical emergency. We therefore give you some advice on how to react in time to heat stroke.

What is heat stroke and why does it occur?

A heat stroke is a condition caused by the harmful effects of high temperatures. It occurs when our body temperature rises rapidly and we are unable to lower it, either because it is too hot, because we have made a very intense physical effort or because we have not hydrated ourselves sufficiently. Special care must be taken with children and the elderly or people with previous pathologies, as they are the most vulnerable groups when it comes to suffering from heat stroke.

How to act and what steps to take if you suspect heat stroke?

  • Recognise the symptoms. Symptoms of heat stress include dizziness, confusion, red, hot and dry skin, rapid and strong pulse, headaches and nausea. If someone shows these signs, it’s time to act!
  • Move the person to a cool, shaded place. The sooner you get the person out of the heat, the better.
  • Place them in a semi-sitting position with their head raised to facilitate breathing. If their condition worsens, you can lay them down with their legs elevated.
  • Reduce the body temperature of the affected person by removing some clothing or by blowing air through a fan or ventilator.
  • Apply cold compresses. Soak a towel or cloth in cold water and place it on the affected person’s forehead, neck and armpits. Avoid direct contact with very cold water, as sudden changes in temperature can lead to complications.
  • Offer fresh liquids. Give the person cool water to drink, preferably in small sips. Avoid alcoholic or caffeinated drinks to prevent aggravating dehydration.
  • Call emergency services. If symptoms worsen or the person does not improve after a few minutes, call emergency medical services.
  • Stay with the affected person. While waiting for emergency services, be sure to stay close to the person and provide support. Stay calm and reassure them.
