As summer approaches and temperatures rise across the country, residents are advised to take precautions while venturing outdoors to prevent a heat stroke.

The Pakistan Meteorological Department (PMD) has issued an alert saying a heatwave would grip Karachi next week for three days from May 1-3, with temperatures to range from 40 to 42 degrees Celcius accompanied by dry and hot winds.

With Karachi expected to remain hot and dry in the coming days, we take a look at the symptoms of a heat stroke and measures that can be taken to prevent it.

What is a heat stroke?

Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system.
