What is a Heatwave?

A heatwave is a period of unusually high temperatures that lasts for several days or weeks. In Pakistan, heatwaves usually occur between May and July, when temperatures rise rapidly due to dry winds and lack of rainfall. This year, experts are warning that the heat may last longer than usual, and might be more intense because of climate change.

Effects of Heatwave :

Heat waves can cause serious health problems, especially for children, elderly people, and those who work outdoors. Here are some common heat-related illnesses:

Heatstroke: This is the most dangerous condition. The body temperature goes above 40°C and the person may faint, feel confused, or even lose consciousness. It is a medical emergency and needs immediate attention.

Dehydration: When we sweat a lot, our body loses water and minerals. If not replaced, this can lead to weakness, dizziness, and confusion.

Heat exhaustion: This includes heavy sweating, nausea, headache, and feeling tired all the time.

Sunburn: Direct exposure to the sun can burn the skin, especially for people with sensitive skin.

Impact on Daily Life

Apart from health, heat waves affect our daily life in many ways:

Power Load Shedding: Increased use of fans and air conditioners puts pressure on the electricity supply, leading to more load shedding.

Water Shortage: With higher temperatures, the demand for water increases. Many areas face water supply issues.

Work Productivity: Outdoor workers like farmers, laborers, and street vendors find it extremely hard to work during peak sunlight hours.

Crop Damage: Heat can damage crops and reduce agricultural productivity, leading to food supply issues and price hikes.

How to Protect Yourself During a Heatwave

Here are some simple and practical tips to stay safe:

1. Stay Hydrated

Drink plenty of water throughout the day—even if you don’t feel thirsty. Avoid sugary drinks, caffeine, and sodas. Use traditional drinks like sattu, lassi, and lemon water to stay cool.

2. Wear Light and Loose Clothing

Choose cotton clothes that are light in color and loose-fitting. Cover your head with a cap or scarf when going outside.

3. Avoid Going Out During Peak Heat

Try to stay indoors between 11 AM and 4 PM, when the sun is at its peak. If you must go out, use an umbrella or wear a wide-brimmed hat.

4. Use Fans and Ventilation

If you don’t have access to air conditioning, use fans and keep windows open in the early morning and evening to allow fresh air to circulate.

5. Eat Light Meals

Avoid heavy and oily food. Eat fruits and vegetables that have high water content like watermelon, cucumber, oranges, and tomatoes.

6. Take Care of Children and Elders

They are more sensitive to heat. Keep them indoors, give them cool drinks, and monitor for signs of heat illness.

7. Be Aware of Symptoms

Know the warning signs of heatstroke and dehydration. If someone is fainting, has a high fever, or shows confusion, take them to a hospital immediately.

Government and Community Role

The government should ensure the availability of clean drinking water, medical facilities, and uninterrupted electricity during heat waves. Awareness campaigns through TV, social media, and local mosques can help educate people. Communities can also support each other by checking on neighbors, especially those living alone or without proper shelter.



Final Words

Heat waves are becoming more common and severe in Pakistan due to global climate change. While we cannot control the weather, we can protect ourselves and our loved ones with simple steps. Let’s spread awareness and take responsible action to stay safe and healthy in this challenging time.
