How to support somebody living with dementia in hot weather

Dehydration is a common challenge for older people, especially those living with dementia. Take note of these ways to support people with dementia during periods of hot weather.

For many people, a heatwave is a chance to enjoy the hot weather in gardens, parks and outdoor spaces. But the heat can also cause discomfort and a risk of dehydration.

If you have a loved one living with dementia, take note of these ways to support them when the temperatures soar. 

Dementia and dehydration in hot weather

Dehydration is a common challenge for older people, and especially those with dementia. Memory problems mean someone with dementia can easily forget to drink enough water.

What’s more, the part of the brain that recognises you’re dehydrated and sends a message to let you know you’re thirsty doesn’t always work properly. Some medications and dementia-related illnesses can also make dehydration worse.

Our dementia advisers are here for you.

5 tips for preventing dehydration

Here are some simple but effective ways of helping to prevent dehydration during hot weather:

  1. Leave beakers or jugs of water within easy reach. This is especially important for people with limited mobility, who aren’t able to get up and make themselves a drink.
  2. Make drinking easier. Have a clear beaker so the person can see what’s inside (this may not work so well with water) or a brightly coloured cup to draw attention. Make sure the beaker is within the line of sight. Having a beaker that is suitable (not too heavy or an odd shape) can help. Straws might also be a good idea.
  3. Share a drink together. Have a cup of tea or a soft drink with the person and make sure they're drinking during mealtimes.
  4. Leave prompts and reminders. Make sure the person with dementia remembers to drink regularly by leaving notes out for them or putting up notices around the house. You could also set up a phone reminder or set an alarm clock.
  5. Provide high water content foods. Supplement water and other drinks with foods that are high in fluids. Some good options include ice lollies, jelly, ice cream, soup and fruit such as melon. ‘Water sweets’, such as Jelly Drops, can also help the person stay hydrated.

How to recognise dehydration

There are some things that may show a person is dehydrated. If you spot any of the following, encourage the person to drink water immediately and seek medical help if you need. If the condition worsens or doesn’t improve, go straight to the hospital.

  • Increased confusion (compared to typical dementia symptoms)
  • Dark and strong-smelling urine
  • Dry mouth, lips and eyes
  • Headaches or dizziness
  • Feeling tired
  • Not peeing very often (fewer than four times a day).

5 more tips to help people with dementia keep cool in hot weather

1. Make sure the person is dressed appropriately

If someone with dementia is dressing themselves, they might follow their usual routine and forget to dress for the current weather. Light-coloured, loose-fitting clothes made from natural fibres can help keep people comfortable and prevent overheating. A hat or cap for outside is also a good idea.

2. Keep the house as cool as possible

Check that the central heating isn’t on, and invest in some fans if necessary. Keeping the curtains or blinds closed during the day – especially in sunny, south-facing rooms – can also help to keep things cool. Blackout and thermal curtains can help too. In the evening, open the windows to let the warm air out and colder air in.

3. Avoid the midday sun

We’re all advised to stay out of the sun during the hottest part of the day (between 11am and 3pm), and this is even more important for people with dementia. When you’re out and about, seek out plenty of shade. Keep a bottle of sunscreen handy, and make sure it’s reapplied regularly.

4. Find ways to cool off

If someone with dementia is hot and agitated, help them take a cool bath or shower. You could also place a wash cloth and some iced water nearby, so they can dab themselves when they need to. Try putting a frozen bottle of water or ice pack next to a fan, for some DIY air-conditioning.

5. Ask friends and neighbours to pop in and check the person is ok

If you don’t live near the person or are worried about someone – ask a friend or neighbour to pop in and make sure they're ok. They could stay and have a drink with the person and make sure they have everything they need.

I would love one day a week rest bite to look after Elizabeth who is mobile but sometimes confused, she was diagnosed with Alzheimer's dementia mixed in April 2019 and have a tendency to ramble but is easy to get on with, should there be anything out there, donation or payment is no problem. Love to hear from you
I'd recommend ice cream. It was also suggested to me by a consultant as a cheap alternative to protein drinks.
My wife was diagnosed with PCA post cortical atrophy a year ago. She never instigates conversation as well as putting tea bags in the kettle to make tea and often can’t remember her adult children’s names. Her memory is bad but when told claims she remembers. She has retained her practical skills such as badminton and is mobile. She is 69. Anyone any advice on the likely progression of this condition?

This is a very helpful website. My husband has been diagnosed with dementia and it is becoming very challenging for me. He repeats himself over and over and though on meds, has become totally dependent on me. So appreciate hearing from others.

Michelle I work with many dementia patients and you can always come to me if you need someone to lean on. Being so close must be so very hard. Please reach out if you need support xx

My parents used to live miles away from me. my Mother was the main carer who looked after my dad who has alzhheimers/dementia. When mum became ill they both moved in with me. Mum died 3 months later with lung cancer which the nurse missed. dad is now with me, Im having tobe a quick learner but it is so hard at times mentally exhausting and frustrating. Lockdown didnt make it any easier. It feels like i am now the parent of my dad. This disease takes eveything away not just for my dad but as a carer as well. Dad cant be left on his own so I am with him 24/7. My partner does help but he finds it hard for himself but he has work that takes him out of the situation. I work from home but its very difficult to look after dad and carry on looking after the house and my job together with my dad. My head at times feels like it just wants to explode. Every day the same old questions day in day out. I love my dad but i now look at him and think your in there somewhere. I will keep him with me for as long as i can. I hear so many bad things about homes, so i just carry on.

dementia and alzheimers are very difficult for the carer my late husband had the condition . the one thing i learnt you can not do it alone you need a support network and looking after yourself is so essential have a support group you can share your problems with often you help each other dont underestimate the gift of sharing and having help you must have time to yourself to recharge your batteries having friends to let of steam and use the help line to talk

I agree. Always been so independent and now feel unashamed in asking for support. thank you

You are definitely right. My mum has dementia and lives with me. We have no other family and it is extremely hard taking on the whole burden. We have good neighbours but I can’t bring myself to ask them for help because I’m frightened they would think I was a nuisance. I am going to possibly utilise a sitting service but mum doesn’t know she has Dementia and wouldn’t take lightly to having a stranger in the house. It’s very difficult. It has been a bit better now we can go out more often. During the lockdown it was horrible. Mum deteriorated rapidly as she’d been used to popping into town on her own every day. She’s unable to do this now. I have to be with her. I love her to pieces but you do still need a break.

hi jennifer you are the pin king in your mothers care so it is important to keep well if you fall ill what would happen to your mum . many years ago i had similar situation with my late husband . i approached my g p and shared everthing and he spoke to my husband explaining that i needed a small break so he could continue in his own home often it comes better from the doctor i wish you well and the more we share our problems we can help each other . we all need back up .

My Father has vascular dementia. I absolutely hate it. It’s a disgusting, cruel waste of human life. Truly, I would not wish it on my worst enemy. It breaks heats and minds and is never ending in its wake to increase misery with every waking hour, it seems. However, we must never, ever, ever lose hope because sometimes that’s all we have left. Don’t let dementia take that away from you as well. There may be a cure one day…we cannot say there won’t be. For us now, living with it, we must help each other to get through each day, shoulder to shoulder. We are a community of sufferers who go on each day, silently grieving and stumbling along. Yes, I hate dementia but I love my Dad.

Ah Yvonne, I feel your pain and, yes, it is a dreadful disease which robs us as well as our loved ones of life. It is impossible to describe to those who do not know a sufferer the frustration, sadness , irritation and exasperation that we feel. Take care and find every way you can to relieve your own stress .

My husband has vascular demntia, he is now 90yrs, was diagnosed 12 yes ago. He went into a rest home in march, very sad and upsetting. I am able to visit him. Yes Yvonne I agree with u. Bless u my thoughts r with u. X

Very true. My mum has mixed Dementia and lives with me. Some days I don’t recognise the person she once was. I feel like I’m in a living nightmare. Don’t even have an other family to share the burden.

Hi Jennifer. I can totally relate to your feelings. My husband Vic had mixed dementia. Some days are so difficult, I only get a yes or no as conversation is sometimes none excistant . I find myself having to do everything which I also sometimes find very difficult with my own health issues. . I also get very concerned about the future. Take care of yourselfs. Margaret.

you are so right we must become a support network for each other keep sharing your story i keep doing this even though for me its in the past take care of yourself yvonne

I'm so sorry for what you are going through. My mom has the same. She changed very slightly for the past 10 years until i couldn't take care of her due to her aggression and just not being able to find proper help or family support. She's in a memory care unit and finally doing well. It took me awhile and a visit to the hospital for exhaustion after she was safe.

I would to say yes it is a slow process but the government can make it better for people that have it ie make depts understand it better and be against the people that have it and make better for there familys that have put up with it it's bad enough when someone you love have it and you see them go down bit bay bit and have to pay for there rest of there life what life they may left.

A quiet pedestal fan can make a big difference in hot weather.

A heatwave can lead to a vicious cycle. People with dementia may forget to drink enough fluids and wear suitable clothing. Dehydration and high body temperatures can lead to greater confusion.

As temperatures rise, we are urging relatives, carers and others to check in on people with dementia to make sure they are OK. Stay hydrated by drinking plenty of water, eat regularly to replace salts, dress in cool, light clothes and stay out of the heat.

Lots of love from Ashridge Home Care

I'm sure this has been considered but the "Jelly Drops" look rather large. I worry about the risk of it getting stuck in the throat, unless it just dissolves when it enters the mouth.

I just saw on Facebook that there is a new jelly pop that is being tested in England that would help in dehydration. They are colorful, room temperature and sound very useful.

My mother has dementia and I have found that giving her C b d caps every day has helped her no end I have also changed her diet slightly so she has plenty of fruit and veg, no cheese or white bread and included walnuts into her diet as well as organic extra virgin olive oil.
Hope this may be of some help to someone else.

Is there a particular reason for avoiding both bread and cheese other that calorie management?

My husband has Parkinson's and dementia. He is getting steady worse over the last 6month, some days it's a battle of wills , and he can say some hurtful thìngs .he crys and ask where mam is, my mother died 5years ago ..he keeps going on about when are we moving , and has many hallucinations.,of which he talks away to them. And gets nasty because I cannot understand him most of the time.he also sleeps a lot.. l have too cut up his food and sometimes feed him..but he is still my husband , and he can have a few realistic moment's. Especially when he sees family..where this is going I have no idea , just live day to day ...

My father got it, and I want to help him and the people who suffers it. Is so hard for me. I just have my self to support you in your activities or task. Some times I feel lonely in this situation .
Thank you for read me
