High humidity in UK high temperatures

DH recently had a heart attack and is currently very uncomfortable during the current high temperatures since he came home from hospital.
I’m wondering if a de-humidifier would help him by making the heat in our apartment drier but maybe I’ve got the wrong idea.
Can any of you knowledgeable gransnetters help please?

I’m sure that would help.

My DH also has heart problems, and over the years I have learned what he can tolerate.

So once it goes over late 20s - 30s, any exertion is a no, and we go to the shadiest side of the house and completely relax.

Lots of fluid.

Everyone’s heart has to work harder in excessive heat or cold and this is what kills the elderly off. So north side of house, shade, rest, fluid and enjoy😊. Tennis is a good past time or reading etc.

I think that the best time for any exercise is early morning.

Just to say that I found that what helped my DH when he was first home from hospital, was that we sort of made his forced rest etc a time of maximum enjoyment. So delicious drinks, and delicious, but healthy food. A good film or in DHs case sport. So rather on dwelling on the downside, we went for the upside of R&R.

A de-humidifier would have a bad effect. Humidity is already quite low ie in the 40s. I have a humidifier on in my bedroom all night, set at 55 and am expecting another identical humidifier for my lounge to arrive via ebay . Right now, I am deliberately drying my washing inside my lounge

I have a portable little air conditioner. It makes a HUGE difference. My thermometer hanging on my patio doors showed 39 degrees yesterday. A dehumidifier would make absolutely no difference to the heat of a room. As long as you have a window or door you can put the exhaust pipe out you should be able to use it. I highly recommend using an air conditioner. If you have any more questions please ask.

Your dh probably feels hot and sticky because the skin is working overtime to cool himself via perspiration. Do you have a device that actually measures humidity inside the room?

I would suggest cooling compresses for now, his blood circulation may well need a bit of help

Put a few damp flannels in the fridge

Whethertomorrow. I’m completely with you there. My aircon machine has made my overheated life so much easier.

Also you can wet a shirt or T-shirt, wring it out and wear it. Feet or hands in a bowl of water. Cold water on veins near the skin like the inside of wrists will help too.

I have to say last night I had very little sleep and when I did finally drop off I awoke suddenly and my heart was absolutely racing, it was quite frightening. This is the first year the heat has affected me like that, I am 82 in September.

I have my 20l dehumidifier running every night on the night setting all year round . In the colder months it's keeps the condensation away and in the summer takes the moisture out of the air so I can sleep and be cool. Hot or cold weather effects my breathing but at home using the dehumidifier never have a problem. When out have to use my GT spray.

In the colder months even on night time setting in it dries my washing in the spare room . When using them you need to keep the door shut. It's amazing how much moist there is in the tank of a morning.

I have a rare hereditary neurological condition,PAF and have a small hole in the side of my heart. I know the dehumidifier helps me.

To cool your husband down I’d suggest getting some dog cooling mats OP. If he puts one on his back it will cool him down quickly. They aren’t expensive, and really work. I use one as a pillow, and keep a spare one to use when that warms up - they cool down at normal room temperature if you leave them for a while. When it’s really warm, I put them in the fridge before I go to bed, for about an hour,

We have the same, perfect solution.

DH is having a long relaxed cool bath before bed each night. He lies in ti for half an hour or more so that his core temperature is reduced and this assures him a good nights sleep.

Allira Fri 20-Jun-25 16:03:23

We have some cooling towels that you can wet, put in the fridge then put on the back of your neck.

Other makes available.

A portable aircon unit would be a good idea, you could move it to the bedroom too.

Just measured the water in my dehumidifier from last night put on at 10am turned off at 5am 10.5ls of water. I empty it every morning. First time I measured it. Had a lovely cooling sleep .

My local lidl has portable air con unit for around £125 in today.

Newtothissite Sat 21-Jun-25 13:54:34

Definitely portable air con or at least a fan.

My DH has a dodgy heart too, and though he's always liked hot weather he's got the air conditioner on this afternoon. I agree with karmalady that the humidity isn't actually too bad today, where we live by the river there is a bit of a breeze which helps.

We seem to get on well with fans. One pedestal fan oscillating in the lounge, one static at foot of bed at night and a desk top one to move around. I'd be worried about getting dehydrated with a humidifier. We only seem to need the lowest setting too. We both have heart conditions.

RedRidingHood Sat 21-Jun-25 15:07:23

Portable air con is my best purchase ever. It may only get used a handful of times a year but it can take a room from fierce oven to pretty chilli in a couple of hours. It does dry you out a bit though.

Humidity is only uncomfortable combined with heat. Fans and air con all dry the air and the person and I find being too dry unpleasant.

Wethertomorrow Just this morning read some warnings about using electric fans in an effort to keep cool. Know a fan isn't quite an air conditioner. Temp between 20 - 29C fans are okay. Once into 30s definitely not. People think that a fan cools the air but the articles pointed out fans only move the air in a room around, not a actually cooling the air. I have a fixed air conditioner (also heats) system and haven't use it in the recent hot spell, just opened windows and doors, closed blinds when appropriate. Think one of the news items was from BBC.

A dehumidifier will raise the temperature very slightly. I would be more inclined to look at small portable air conditioning units to bring temperature down.

Whiff if you have pot plants in your bungalow the dehumidifier water is very good for watering them 👍🏻

Our dehumidifier on the landing is full every morning as well.

The person to ask is a doctor!
