What Causes Summer Heat?

The Earth revolves around the sun in an oval-shaped orbit. When it's tilted toward the sun, it receives more direct sunlight — and that’s what gives us summer.

During this time:

  • Days are longer

  • The sun’s rays hit more directly

  • The ground absorbs more heat

As a result, temperatures rise — especially in cities, where concrete and buildings trap heat.

🔥 What Is a Heatwave?

A heatwave is a period of unusually hot weather that lasts for several days. It’s not just about feeling hot — it can seriously affect health, water supplies, farming, and even power systems.

In many places, heatwaves are becoming more common and intense due to climate change.

🌍 Summer Heat Around the World

In recent years, summer temperatures have hit record highs across the globe:

  • India: Many cities often cross 45°C (113°F) during May and June. States like Rajasthan and Delhi experience severe heatwaves almost every year.

  • Middle East: Places like Kuwait and Iraq have recorded temperatures above 50°C.

  • Europe: Countries like France and Spain now face frequent heat alerts during summer.

  • USA: States like Arizona, Nevada, and Texas often deal with dangerous heat levels.

😓 How Does Extreme Heat Affect Us?

High temperatures can lead to:

  • Dehydration

  • Heat exhaustion or heatstroke

  • Dizziness and headaches

  • Dry skin and sunburn

  • Breathing problems for people with asthma or lung conditions

It can also affect crops, dry up rivers, and increase the risk of wildfires.

🧊 How to Stay Safe in Summer Heat

Here are some simple tips to stay cool and protected:

🌴 Stay Cool:

  • Wear light-colored, loose-fitting clothes

  • Use fans or air conditioning

  • Stay indoors during peak heat (12 PM – 4 PM)

💧 Stay Hydrated:

  • Drink plenty of water

  • Avoid sugary or caffeinated drinks

  • Eat juicy fruits like watermelon, oranges, and cucumbers

🧴 Protect Yourself:

  • Use sunscreen when going outside

  • Wear a hat and sunglasses

  • Walk in the shade when possible

🌡️ Why Is It Getting Hotter Each Year?

Due to global warming, the Earth's average temperature is rising. Burning fossil fuels like coal, oil, and gas adds greenhouse gases to the atmosphere. These gases trap heat, making summers hotter and winters warmer too.

If we don't act soon, heatwaves will become more frequent, last longer, and be even more dangerous in the coming years.

🌱 What Can We Do to Help?

Even small steps can make a difference:

  • Plant trees — they provide shade and cool the air

  • Save energy — turn off lights and appliances when not in use

  • Use public transport or cycle instead of driving

  • Support clean energy and climate action
