Signs of Heat Stroke (Check if body is not cooling down)

What is it?

Once a body temperature reaches greater than 40.5°C (105°F)  at any moment or Fever of temperature greater than 38°C (100°F) not cooling or calming down after 30 mins, heatstroke can set in.

  • Indicators are similar to heat exhaustion but the person may lose consciousness, have dry skin and stop sweating.

When we are surrounded by heat our bodies get hotter, if one is exposed to too much heat, our bodies want to cool down to a temperature of approx 37 degrees Celsius so it does the following:

  • As the body gets hotter, blood vessels open up.
  • This leads to lower blood pressure and makes the heart work harder to push the blood around the body.
  • This can cause mild symptoms such as an itchy heat rash and/or swollen feet as blood vessels become leaky.
  • At the same time, sweating leads to the loss of fluids and salt and, crucially, the balance between them in the body changes.
