How to Stay Safe During the Heatwave: Essential Tips for UK Residents

Summer is a great time to enjoy longer days and warmer weather. But in a heatwave it’s crucial to take care of yourself and your home as the temperatures climb. Heatwaves can impact anybody, but young children, older adults and people with underlying health concerns are most at danger.

Below are some simple and practical tips to help you stay cool during hot weather.

1. Keep Your Home Cool

During a heatwave, keeping your home as cool as it can be can make a great difference.

Here are a few simple ways to do this:

• Close curtains or blinds during the warmest portion of the day to block direct sunlight.
• Take advantage of the cooler parts of the day by opening your windows in the morning or after the sun begins to set.
• Creating airflow by opening windows on opposite sides of your home can help keep rooms feeling fresher and cooler.

These small changes can help keep indoor temperatures more comfortable.

2. Stay Hydrated

If you are outside in hot weather, drink water often to keep your body cool, even if you don’t feel thirsty.

Try to:

• Don’t wait until you feel thirsty—drink water regularly to help your body stay hydrated.
• Carry a reusable water bottle when you’re out.
• To help your body stay hydrated, reduce your intake of drinks with caffeine or alcohol and choose water regularly throughout the day.

Keeping hydrated helps your body regulate its temperature.

3. Avoid the Hottest Part of the Day

The sun is usually strongest between 11:00 am and 3:00 pm.

If possible:

• Stay indoors during these hours.
• Plan outdoor activities for the morning or evening.
• Whenever you’re outside, look for shaded spots to help keep cool and reduce your exposure to the sun.

4. Wear Lightweight Clothing

• Choose clothing that helps your body stay cool.
• Light-coloured, loose-fitting clothing made from breathable fabrics such as cotton can make hot weather much more comfortable.
• Don’t forget sunglasses and a wide-brimmed hat if you’re spending time outdoors.

5. Protect Yourself from the Sun

Sunburn can happen quickly during a heatwave.

Remember to:

• Apply sunscreen before going outside.
• Reapply it if you’re outdoors for long periods.
• Wear sunglasses that protect against UV rays.

Taking these simple steps helps protect your skin from harmful sunlight.

6. Keep Food Safe

Hot weather can cause food to spoil more quickly.

To reduce the risk:

• Open your fridge and freezer only when you require access and close the doors correctly afterwards to keep a steady temperature.
• Store food correctly.
• Never leave cooked food out for long periods.

Food safety is especially important during the summer months.

7. Look Out for Signs of Heat Exhaustion

Heat exhaustion can happen if your body becomes too hot.

Common signs include:

• Dizziness
• Headache
• Feeling weak or tired
• Heavy sweating
• Nausea

If you experience these symptoms, move somewhere cool, drink water, and rest. If symptoms become severe or do not improve, seek medical advice.

8. Check on Family, Friends and Neighbours

• Some people may struggle more during hot weather.
• If you have elderly neighbours, family members, or anyone living alone, checking in with them can make a real difference.
• A quick phone call or visit could help ensure they are safe and comfortable.

9. Use Electricity Wisely

Electrical appliances generate heat.

Where possible:

• Switch off appliances when they are not in use.
• Turn off lights in rooms you are not using.
• Cook during cooler parts of the day if possible.

These habits can also help reduce energy bills.
