How to prepare for heatwave temperatures

We are usually given a few days warning before a heatwave arrives, so there's time to prepare. You never know exactly how long the heatwave will last, so it's important to be well-prepared.

• Keep informed and stay alert. Follow weather updates and take heatwave warnings seriously. Check for weather warnings in your area and sign up for the UKHSA Heat Health Alert.

• Stock up on food and drinking water. If needed, store water in case there is a problem with your water supply.

• Check fridges, freezers, fans, and air conditioning units are working. If you have a ventilation system in your home, check this is switched on and working.

• Switch your central heating off.

• Check on friends, neighbours, and relatives. Make sure they are aware of the risks and help them with heatwave preparation.

• Babies and children, those with underlying health issues, and elderly people are at particular risk during hot weather. Find out if anyone you know or care for will need additional support.

• Ensure you have enough medication and you know how to store it in hot temperatures.

• A chronic illness, such as a heart, lung, or kidney problem, may get worse in hot weather. Consult your doctor about how best to cope during a heatwave. Call 999 in an emergency.

• Look after your health in a heatwave, so plan ahead to reduce the risk. Stock up on items you may need like sunscreen and rehydration tablets.

• Outdoor activities like like swimming in open water, can be dangerous in hot weather. Learn basic first aid skills to treat burns, heat exhaustion, and spot heat stroke to help in an emergency.

• Vehicles can be affected by high temperatures and long periods of hot weather. To stay safe on the road, check your tyres, fluid levels, battery, and air conditioning work. Carry water in your car in case of a breakdown.

• Know who to contact in an emergency. You can call NHS 111 for medical advice or 999 in an emergency. Download the British Red Cross emergency app for more information.

• Keep out of the heat during the hottest hours of the day. This is usually between 11 am and 3 pm. If you can’t avoid it, take breaks in the shade.
• Keep yourself covered and protected when out in the sun
• Protect your eyes with sunglasses and wear light, loose clothing. Avoid looking directly at the sun to avoid permanent damage.
• Keep an eye on children and animals, who are more vulnerable.
• Keep yourself hydrated - you'll need more water than usual during heatwave temperatures.     
• Stick to cold foods and drinks and avoid alcohol. Cool yourself down by having cold showers or washing your face.
• Look out for heat stroke and heat exhaustion. Make sure you know the signs and what to do in an emergency. 
• Only make necessary journeys, avoid peak traffic and the hottest hours of the day. Don't bring pets with you during very hot weather.

Children and babies are more vulnerable to increases in temperatures. Pay extra attention to how they are feeling during heatwave temperatures.

• Keep your child covered in light, loose clothing and a wide-brimmed hat. Avoid direct sunlight and reapply sunblock (at least SPF 30 sunscreen).
• Reduce play time in the sun to avoid sun burn or overheating. If you are outside, stick to the shade especially when the sun is at its strongest.
• Learn how to spot heat exhaustion and heat stroke in a child or baby. If you suspect heat stroke symptoms, then call 999. •
• Children and babies can become dehydrated quickly. Give plenty of fluids and monitor closely.
• Don't leave children unsupervised in a car. Even with windows slightly open, a child or baby left in a car is at serious risk of heat-related illnesses.  
• Schools and nurseries will have their own procedures for heatwave weather. Make sure you are in contact with them and aware of any changes to the normal routine.
