Caring for someone with dementia in hot weather

Hot weather can be challenging for anyone, but it brings particular risks for people living with dementia. Changes in the brain can affect how someone recognises thirst, senses temperature or communicates discomfort. If you're supporting someone with dementia, here are some practical ways to keep them safe and comfortable when temperatures rise.

1. Keep them hydrated 

People with dementia may not remember to drink or recognise when they're thirsty. Encourage small sips throughout the day rather than large drinks all at once. Offer a variety of options, like water, squash, fruit juice or an ice lolly. Foods with a high water content - such as watermelon, cucumber, jelly or yoghurt - can also help.

2. Stay cool indoors 

Keep curtains or blinds closed during the hottest part of the day, usually between 11am and 3pm. Open windows when it's cooler outside. If possible, use a fan or cooling device. Avoid too many layers of clothing and choose loose, breathable fabrics like cotton. Use a cool, wet cloth to wipe their face, neck and arms.

3. Avoid the midday heat 

If you need to go out, aim for early morning or late evening. Make sure the person wears a hat, sunglasses and sunscreen. Look for shaded areas to rest and keep outings short.

4. Watch for signs of heat-related illness 

People with dementia might struggle to explain how they're feeling. Watch for signs like headache, dizziness, confusion, tiredness or dry mouth. If you notice anything unusual, offer fluids, help them rest in a cool place and seek medical advice if needed.

5. Summer clothes  

The person you care for may not always recognise when it’s hot outside or know how to dress for the weather. They might choose clothes that are too warm, like jumpers or coats, even on a hot day. To help, lay out a suitable outfit, choose light-coloured, loose-fitting clothes made from breathable fabrics like cotton or linen.

6. Check in regularly 

If you don’t live with the person, try to check in by phone or video call. If you are worried about someone – ask a friend or neighbour to pop in and make sure they're ok.
