Summer brings longer days, sunshine and opportunities to spend time outdoors. However, warm weather can also present unique challenges for people living with dementia.
Even on moderately warm days, individuals with dementia are at a higher risk of dehydration, heat exhaustion and confusion, making it essential for carers, families and healthcare professionals to take extra precautions.
Whether you're caring for a loved one at home or supporting residents in a care setting, here are some practical ways to help someone with dementia stay safe and comfortable during hot weather.

Why Is Hot Weather More Challenging for People with Dementia?
People living with dementia may experience changes that make it harder to cope with warmer temperatures. They may:
Forget to drink enough fluids.
Be unable to recognise when they feel thirsty.
Wear unsuitable clothing for the weather.
Forget to seek shade or move to a cooler room.
Become confused or agitated when they feel too hot.
Have health conditions or medications that increase the risk of dehydration.
These factors mean that carers need to be proactive rather than waiting for the person to say they are uncomfortable.
Encourage Regular Fluid Intake
One of the most effective ways to prevent heat-related illness is to encourage regular hydration. Rather than asking, "Would you like a drink?", offer drinks little and often throughout the day. Good fluid options include:
Water
Milk
Diluted fruit squash
Herbal teas
Fresh fruit smoothies
Ice lollies made from fruit juice
Foods with a high water content can also help, including:
Watermelon
Strawberries
Cucumber
Oranges and
Yoghurt.
If the person enjoys tea or coffee, these can still be included as part of their daily fluid intake, although water should remain the main source of hydration.
Maintain a Cool, Calm Environment
Creating a comfortable indoor environment can significantly reduce the risk of overheating.
Simple steps include:
Closing curtains or blinds on sunny windows during the hottest part of the day.
Opening windows early in the morning or later in the evening when temperatures are lower.
Using electric fans safely to improve air circulation.
Encouraging the person to spend time in the coolest room of the house.
Switching off unnecessary electrical appliances that generate heat.
Reduce noise and clutter — heat can worsen sensory overload.
Ensure the person has a quiet space if they become agitated.
If wandering is a risk, ensure windows and doors remain secure while still allowing airflow.
If the person lives in a care home, staff should regularly monitor room temperatures and ensure communal areas remain well ventilated.
Choose Safe and Comfortable Clothing
Lightweight, loose-fitting clothing made from breathable fabrics such as cotton helps keep the body cool. If going outdoors, encourage:
A wide-brimmed hat
Comfortable footwear
Sunglasses
Lightweight clothing in light colours
Where possible, avoid going out during the hottest hours of the day.
Plan Activities Around Cooler Times
People with dementia often feel more secure when daily routines remain consistent.
Hot weather may require slight adjustments, such as:
Going for walks earlier in the morning.
Sitting in the garden during cooler parts of the day.
Scheduling appointments outside peak afternoon temperatures.
Taking regular rest breaks indoors.
Keeping routines predictable can reduce anxiety while still allowing the person to enjoy the summer months.
Watch for Signs of Dehydration
Because someone with dementia may not be able to explain how they are feeling, carers should watch for physical and behavioural changes. Signs of dehydration may include:
Dry mouth or lips
Dark-coloured urine
Headaches
Dizziness
Increased confusion
Sleepiness
Irritability
Reduced appetite
If you notice these symptoms, encourage fluids immediately and monitor the person's condition closely.
Recognise Heat Exhaustion Early
Heat exhaustion can develop quickly during warm weather. Common symptoms include:
Heavy sweating
Weakness
Nausea
Muscle cramps
Rapid heartbeat
Headache
Feeling faint
Move the person to a cool place, encourage them to drink water and use cool damp cloths to help lower their body temperature. If symptoms persist or worsen, seek medical advice.
When Is It an Emergency?
Heatstroke is a medical emergency and requires urgent treatment. Call 999 immediately if someone:
Loses consciousness.
Becomes extremely confused or unresponsive.
Stops sweating despite feeling very hot.
Has difficulty breathing.
Experiences a seizure.
Has a very high body temperature.
Medication and Safety Checks
Some medications increase sensitivity to heat or dehydration.
Store medicines below 25°C unless otherwise stated.
Monitor for side effects such as dizziness or increased confusion.
Ensure care plans are updated to reflect warm‑weather risks.
Don't Forget Sun Protection
Older skin is more delicate and burns more easily. Even short periods outside can lead to sunburn. Remember to:
Apply sunscreen with an appropriate SPF.
Reapply regularly.
Encourage time in the shade.
Wear a hat whenever possible.
Increase Welfare Checks
People with dementia may not recognise when they’re becoming unwell.
Families and care providers should:
Check in more frequently.
Monitor hydration and appetite.
Observe for changes in behaviour or confusion.
Ensure the home remains cool and safe.
How Professional Carers Can Help
Whether supporting someone in their own home or within a care service, professional carers play a vital role in preventing heat-related illness. Good practice includes:
Monitoring hydration throughout every visit.
Recording fluid intake where appropriate.
Encouraging suitable clothing.
Observing for early signs of dehydration.
Keeping living spaces cool and well ventilated.
Reporting any concerns promptly to family members or healthcare professionals.
Small interventions throughout the day can make a significant difference to someone's wellbeing.
Where warm weather causing situations such as wandering, restlessness, sundowning, agitation and sleep disruption, carers can help by:
Offering reassurance and simple explanations.
Keeping the environment calm and predictable.
Using distraction techniques (music, photos, gentle activities).
Avoiding arguments or confrontation.
