The UK is not built for extreme heat. Our homes, our habits, and our infrastructure were designed for milder summers — which is why a heatwave bringing temperatures of 34 to 40°C feels not just uncomfortable but genuinely dangerous. The Met Office has issued a Red Extreme Heat Warning, indicating a risk to life even for healthy people, and older adults are among those most at risk. This guide is here to help — with practical, gentle advice for staying safe, cool, and as comfortable as possible until cooler weather returns. Met OfficeMet Office
Why This Heatwave Is Different
It isn’t only the temperature that makes this particular heatwave so challenging. High humidity means the body struggles to cool itself through sweating, and consecutive nights are expected to stay above 20°C — what meteorologists call a “Tropical Night” — making it very hard for the body to recover from the daytime heat. For older adults, whose bodies regulate temperature less efficiently than they once did, this combination demands extra care. Met Office
Keeping Your Home Cool
Your home is your first line of defence. A few simple steps can make a meaningful difference to the temperature inside:
Close curtains and blinds in any rooms that get direct sunlight — particularly in the morning on east-facing windows and in the afternoon on west-facing ones. Keep windows closed during the hottest part of the day if the air outside is hotter than the air inside; open them in the evening and overnight when the temperature drops. Move to the coolest room in the house during the heat of the day, often a north-facing room or one downstairs. If you have an electric fan, place a bowl of ice or a frozen water bottle in front of it to cool the air it circulates.
Hydration Matters More Than You Think
In extreme heat, the body loses fluid far more quickly than usual, and the sensation of thirst becomes less reliable with age. Don’t wait until you feel thirsty — sip regularly throughout the day. Water, diluted squash, or fruit juice are all good options, and a balanced diet helps the body replace salts lost through sweating. It’s also wise to limit alcohol, tea, and coffee, which can contribute to dehydration. Age UK
If you take regular medication, check with your pharmacist whether the hot weather affects how it should be stored, and never leave medication in direct sunlight.
Staying Cool Through the Day
Avoid going outside during the hottest hours, typically between 11am and 3pm. If you do need to go out, wear loose, light-coloured cotton clothing, a wide-brimmed hat, and sunglasses, and apply sunscreen of at least SPF 30. Carry a bottle of water with you, and stick to shaded routes wherever possible. British Red Cross
Inside, simple acts can bring real relief — a cool shower or bath, splashing the wrists and back of the neck with cold water, or resting with a damp cloth on the forehead. Cold foods such as salads, fruit, and yoghurts are easier on the body than heavy hot meals.
Recognising When Things Are Going Wrong
It’s important to know the warning signs that the heat is becoming a serious problem. Early signs of heat-related illness include headaches, dizziness, excessive tiredness, muscle cramps, nausea, and confusion. If any of these appear, move to a cool place straight away, drink water or a diluted juice, and rest. University of Reading
If symptoms don’t improve within around 30 minutes, call NHS 111 for advice. If someone develops signs of heatstroke — which is a medical emergency — call 999 immediately.
Looking Out for Each Other
This is the time to check in on elderly relatives, neighbours, and friends who live alone. A quick phone call, a knock on the door, or dropping off a chilled bottle of water can make all the difference. For many older people, the heat can also bring isolation — they may not feel able to go out for their usual walk or chat — and a friendly visit lifts both body and spirits.
Heatwaves of this severity are increasingly part of our British summers, and learning to adapt is essential. At Lakeshore Care, we’re paying close attention to the wellbeing of everyone we support during this exceptional weather — helping with hydration, keeping homes cool, and ensuring that no one is facing this difficult few days alone. If you’re worried about an elderly loved one during this heatwave, please don’t hesitate to reach out. Cooler days are on the way, and we’ll get through this together.
