All of us have heard warnings regarding the adverse effect of climate change, and now we can see them as well. Recently, Pakistan Meteorological Department (PMD) issued a heatwave warning as the temperature soared above forty degrees Celsius in many parts of the country.
The temperature during April was also at a record high. Urban centers such as Lahore and Karachi are experiencing the most intense temperatures. Citizens were advised to avoid going in the sun unnecessarily.

What is a heatwave?
Long durations of abnormally high temperatures are known as heatwaves. The temperatures may vary from country to country. Usually, a heatwave occurs when the temperature rises ten degrees or higher than the usual temperature in a region.
High pressure in the upper atmosphere is the culprit of the increase in temperature. It pushes warm air downwards and compresses it, resulting in soaring temperatures and scorching heat.
Heatwaves can lead to heat stroke and exhaustion. Here are the signs to watch out for:
- Excess sweating and panting
- Breathing difficulty
- Rapid Heartbeat
- Flushed and hot skin
Keep a lookout for these signs in others, as well as yourself, because heatstroke can be deadly if not treated at the right time. If you feel symptoms of heatstroke, consult a General Physician in Lahore as soon as possible. Someone fainting around you can be a sign of heatstroke and needs immediate medical attention.
Heatwave in Pakistan
Extreme temperatures are not new to Pakistanis. The energy and fuel sources in Pakistan are dependent on coal, oil, and natural gas. These contribute to the high temperatures and unprecedented changes in the weather in the South Asian region.
The situation has become alarming in the last few years because of the early onset, intensity, and duration of heat spells. It has also cut short the season of spring in Pakistan. Many people have become ill, and in some worst cases, people died due to the dry spells of hot weather. In a recent tweet by Pakistan’s Federal Minister for Climate Change, Sherry Rehman said,
“Climate change is national security now: it impacts food & water security, the air we breathe, the soil we exploit, & strips the country of vital resources, impacting anywhere from 4-6 % of GDP. Yet the biggest challenge is awareness, in multiple circles.”
The surprising and sudden rise of temperatures in most areas of Pakistan shows that urgent action needs to be taken by the government to create awareness of climate change and work towards mitigating its effects. If preemptive action is not taken, the situation is likely to get worse in the coming years.
Preparing for a heatwave
Several warnings have been issued regarding the heatwave, and Pakistan may face more severe heatwaves. It is best to prepare for such occurrences in advance. Here are a few tips that can help you in preparing for unbearably hot weather.
- Install an air conditioner or any other cooling device to manage the temperature inside the house.
- Insulate your windows, especially where the sunlight hits directly.

- Wear sunscreen to protect yourself from harmful UV rays.
10 ways to protect yourself from a heatwave

2. Hydrate yourself
Hydration is crucial to surviving in insufferable heat. Ensure that you are drinking enough water, whether in or out of the house. Keep an extra water bottle in your case in case of an emergency. Eating fruits and vegetables with high-water content can also aid in keeping your hydration up. Get enough electrolytes to keep your energy high.

4. Keep indoors protected
Switch on the air conditioner when the temperature gets too hot. Install blinds or drapes to keep the sunlight out.
