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.
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.
Those suffering from heatstroke may exhibit signs and symptoms such as:
- High temperature but without sweating
- Throbbing headache
- Dizziness and light-headedness
- Lack of sweating despite the heat
- Red, hot, and dry skin
- Muscle weakness or cramps
- Nausea and vomiting
- Rapid heartbeat, which may be either strong or weak
- Rapid, shallow breathing
- Behavioural changes such as confusion, disorientation, or staggering
Here are some measures you can take to shield yourself from a heat stroke:
- Avoid strenuous activity
- Wear lightweight, light-colored, loose-fitting clothing
- Wear a wide-brimmed hat or cap
- Use sunscreen
- Take frequent showers
