Staying hydrated in the heat

Hot weather increases the risk of dehydration, and for people living with dementia, that risk can be even higher. Memory difficulties and trouble communicating may mean someone forgets to drink or struggles to ask for help. But with some gentle routines and practical tips, it’s possible to stay well and comfortable during the warmer months.

Know the signs of dehydration

These might include tiredness, dizziness, dry mouth or lips, headaches and passing dark urine. In people with dementia, dehydration can also show up as sudden confusion, agitation or changes in behaviour. These signs aren’t always easy to spot, so it’s worth encouraging regular drinks even if they seem fine.

Keep drinks in easy reach

Water is best, but variety helps - diluted juice, squash or smoothies can be easier to enjoy. Try to build drinking into daily routines: with snacks, after using the toilet or before heading outdoors. Some people respond well to visual cues, like a full cup placed nearby. Familiar mugs or colourful beakers may help prompt independent drinking.

Hydrating foods can also help

Many fruits and vegetables - such as watermelon, cucumber, tomatoes, peaches and strawberries - have a high water content. Ice lollies, jelly and yoghurt drinks can help too. These can be helpful when someone prefers food over fluids.

Share a drink together

Sitting together with a drink, sharing a snack in the shade, or including soft music can turn a drink break into a calming moment. It can also help someone feel more in control and less resistant to support.

Be mindful when it’s hot

Spending time outside, when the weather is hot, can quickly lead to dehydration. Even short walks or time in the garden can raise their body temperature more than expected. It’s important to plan ahead - bring water bottles, seek out shaded spots to rest, offer drinks regularly, even if they don’t ask. Keeping hats, cooling cloths or fans handy can also help manage heat and reduce the risk.

If you’re worried, don’t wait

Signs of serious dehydration - like fainting, confusion, dry skin, or ongoing vomiting - may need urgent medical attention. Contact a GP, NHS 111, or emergency services if you’re unsure.
