🎧 Listen to this article

Urban heatwaves are on the rise during summer, especially in urban areas, negatively impacting your health, lifestyle, and safety due to rising temperatures. In cities, the heat generated by buildings, roads, and vehicles, the loss of natural vegetation, and air pollution create the urban heat island effect. This causes you to experience high temperatures, high humidity, and less cooling at night. In this article, you will learn about safety tips, hydration tips, and precautions to protect yourself from the heat in cities. By following these tips, you and your family can protect yourselves from heatstroke,

Quick-Revision Table – Urban Heatwave Safety

Category	Key Points
Heatwave Risks	Concrete stores heat; nights stay hot; long spells cut body cooling; risk rises.
Hydration	Drink water often; skip coffee, alcohol, sugary drinks; eat water-rich fruits.
Clothing & Protection	Light, loose cotton or linen; light colors; hat or scarf; UV sunglasses.
Outdoor Safety	Avoid 11 am–4 pm; choose shade; carry water, hat, sunglasses, umbrella.
Home Cooling	Block the sun with curtains; ventilate mornings/evenings; add plants for shade.
Illness Signs	Exhaustion: sweat, fatigue, headache. Heatstroke: confusion, dry skin, fever.
Care for Vulnerable	Keep the elderly, kids cool; limit outings for pregnant/chronically ill; ensure fluids, food.

What Are Urban Heatwaves and Why Are They Dangerous?

Heat waves occur in cities when high temperatures persist for a long time. The heat wave effect is greater than in rural areas (outskirts and villages) because urban structures (concrete jungles) absorb heat and release it at night.

• Since urban heatwaves last longer, the body loses its natural cooling ability, leading to health problems.

• The lack of a drop in nighttime temperatures can reduce your body's ability to rest.

• The elderly, children, pregnant women, and those with heart or lung problems are at higher risk.

How to Stay Hydrated in Rising Temperatures?

Hydration is especially important during hot weather. Dehydration can make it difficult for your body to regulate its temperature.

• Drinking water frequently throughout the day, even when you're not thirsty, can help keep your body hydrated.

• Reduce your intake of coffee, alcohol, and high-sugar drinks, which can accelerate dehydration.

• Include fruits and vegetables with a high water content, such as watermelon, cucumber, and oranges, in your diet.

What is the Right Clothing During Urban Heatwaves?

Your clothing plays a key role in reducing the effects of heat. The right clothing will keep your body cool.

• Lightweight cotton, linen, bamboo fabrics allow air to pass through easily, and sweat dries quickly.

• Moisture-wicking fabrics that absorb moisture keep the body cool

• Loose clothing – allows air to flow easily and reduces heat.

• Light colors – absorb less sunlight.

• Light clothing that covers arms and legs protects against UV rays.Hat/scarf that covers head and neck – prevents sunstroke.

• UV protection goggles for eyes.

How do Outdoor Activities at Peak Heat Hours affect You?

It is best to avoid going outside during peak heat hours during heat waves.

• Limit outdoor activities, especially between 11 am and 4 pm, during hot weather days.

• Choose shaded areas when you must go out.

• Carry sufficient water, a hat, sunglasses, and an umbrella with you when traveling, especially during hot weather.

Heat-Related Illness & Solutions

Illness / Risk	Quick Solution
Heat Cramps	Drink electrolyte-rich fluids, and rest in a cool place.
Heat Exhaustion	Move to shade, sip water, loosen clothing.
Heatstroke	Call emergency help, and cool the body rapidly.
Heat Rash	Keep skin dry, wear loose, breathable clothes.
Sunburn	Apply aloe vera, avoid direct sun exposure.
Worsening Chronic Disease	Stay cool, follow the doctor’s advice, and hydrate well.
Infectious Disease Spread	Maintain hygiene, and use mosquito control methods.
Skin Cancer (Melanoma) Problems	Long sleeves, wide-brimmed hats, and UV-blocking fabrics. Avoid peak sunlight hours (10 AM–4 PM).

Why Keep Yourself Home During Hot Weather?

Heat waves, periods of abnormally high temperatures, can pose serious health risks and lead to various illnesses, ranging from mild discomfort to life-threatening conditions. Extreme heat can lead to heat cramps, heat exhaustion, heatstroke, heat rash, and sunburn. It can worsen chronic conditions like cardiovascular, respiratory, kidney disease, and diabetes. It can also contribute to infectious diseases, food and water contamination, and illness spread in crowded, cool spaces. Vulnerable groups need special attention. Seek medical help if symptoms appear. For medical advice, consult a professional.

Keeping your home cool naturally is not only energy-saving but also good for your health.

• Block direct sunlight from entering your room by using curtains, blinds, or shades.

• Create airflow by opening windows in the morning and evening.

• Growing plants and trees around the house can provide natural shade and cool air.

How to Identify and Prevent Heat-Related Illnesses?

It is very important to recognize the symptoms of heat exhaustion or heatstroke caused by heat exposure early.

• Excessive sweating, fatigue, headache, and vomiting are signs of heat exhaustion.

• Symptoms such as confusion, dry skin, and high fever are signs of heatstroke, and immediate medical attention should be sought.

• To prevent these, it is necessary to drink enough water, rest in the shade, and eat light meals.

How to Protect Vulnerable Groups from Urban Heatwaves?

The effects of heat are more dangerous for certain groups. They need special attention.

• The elderly and children have weak body temperature control, and they should be kept in cool places.

• Pregnant women and people with chronic illnesses should avoid going outside.

• It is important to provide these groups with adequate fluids and nutritious food.

Women use various methods like wiping sweat, wearing wide-brimmed hats, and using scarves to protect themselves from the harsh summer sun.

Frequently Asked Questions (FAQs)

1. Why are heat waves increasing in cities?

In cities, heat is stored due to roads, concrete buildings, vehicle emissions, and less greenery. This storage effect causes temperatures to rise significantly over time.

2. During which times should one avoid going out the most?

The sun's rays are at their strongest between 11:00 a.m. and 4:00 p.m. Going out during these hours should be minimized to prevent heat-related health issues.

3. What type of clothing should one wear during a heatwave?

Wear light, cotton clothes in white or light colors. These fabrics improve air circulation in the body and help keep you cooler under the sun.

4. What types of drinks are good during a heatwave?

Consume drinks like water, lemon juice, coconut water, cold milk, and buttermilk. These beverages help maintain hydration and naturally keep the body cool.

5. What should you do to stay cool at home without an air conditioner?

Use screen curtains, hang wet cloths on windows, and increase air circulation with a fan to stay cool without an air conditioner.

6. Why are children and the elderly more affected by heat waves?

Their body temperature control system is weaker, making them more vulnerable to the effects of extreme heat compared to young and healthy adults.

7. What are the symptoms of heat stroke?

Headache, dizziness, excessive sweating, increased body temperature, vomiting, and fainting are the main symptoms of heat stroke.

8. What should you eat during a heatwave?

Eat fruits, vegetables, and water-rich foods more often. Reduce heavy and spicy foods as they increase body heat and discomfort.

9. What precautions should you take if traveling is necessary?

Wear a hat or carry an umbrella, apply sunscreen, and carry water to protect yourself while traveling in hot weather.

10. Can you work out during a heatwave?

Always avoid exercise during extremely hot weather. Instead, do your workouts in the cooler hours of the morning or evening for safety against the bad effects of heat.
