Warmer summer days are mood lifting for most but rising temperature can bring real risks for older people. As we get older, our bodies change how they handle heat. Our internal thermostat does not work quite as efficiently, and the physical sensation of thirst starts to fade. This means an older relative can easily overheat or become dehydrated without ever realising they need a drink.
Why Hot Weather Hits Harder as We Age
The body naturally holds less water as the years pass. This means there is a much smaller reserve to draw from during a heatwave. Compounding this, the brain’s thirst signals become less sharp, so while there may be no warning signs fluid levels could be dangerously low.
Medications can complicate the situation further. Common prescriptions like blood pressure tablets or diuretics cause the body to lose fluids rapidly. When you combine these physical changes with hot weather, summer safety requires a bit of forward planning.
Keeping the House Cool
Beating the heat is mostly about managing the indoor environment. A common mistake is opening all the windows wide during the middle of the day. If the air outside is hotter than the air inside, you are just letting the heat in. Keep windows shut and curtains firmly closed while the sun is beating down on the glass. Once evening arrives and the outside air cools down, open everything up to get a breeze through the rooms.
Lightweight, loose cotton clothing is best because it lets the skin breathe. If someone is starting to feel uncomfortably warm, a damp cloth on the back of the neck or running cold water over the wrists works wonders to drop their temperature quickly. It is also worth shifting the daily routine around. Save tasks like gardening, popping to the shops, or walking the dog for the early morning before the sun gets too high.
Simple Ways to Keep Fluids Up
Simply telling someone to drink more water rarely gets results. If someone has a small appetite, a massive glass of water looks daunting and unappealing. Small, frequent sips throughout the day are much easier to manage.
Water, fruit squash, and milk are all perfectly fine for hydration though you should limit intake of diuretics like alcohol and highly caffeinated drinks. You can also sneak plenty of fluid into meals. Jelly, ice lollies, cold soups, and water-rich fruits like melon or strawberries are great ways to boost fluid intake without making a fuss about it.
Keep a close eye out for the warning signs of dehydration. If an older relative suddenly seems confused, unusually sleepy, or complains of a nagging headache, check their fluid intake. Dark urine is another definitive sign that they need to start drinking right away.
Help and Support
If you want to read up on fluid intake and heat safety, several UK organisations offer excellent, practical guides:
- The British Dietetic Association (BDA) publishes a clear factsheet on hydration for older adults, filled with tips on how to encourage regular drinking. Read it at
- Age UK provides a specific guide on how to spot and prevent dehydration, which includes incredibly useful advice for individuals living with dementia.
- The Royal College of Nursing (RCN) hosts a detailed blog exploring exactly why older people lose their sense of thirst and how caregivers can step in. Visit
