Does the house temperature being 84 degrees make an 85 year old urinate more frequently?

Good grief, 84 degrees isn't healthy at all. Since it is the wife who is not turning on the air conditioner, I would tell her politely [if she will listen] such a hot house can create mold and unhealthy air. Which would make she and her husband sick.

I am dealing with the temperature wars with my Dad at his apartment in Independent Living. I think 75 is a good temperature for him, but he will push up the heat to 80... and the other day when it was 90 degrees out and the sun was shining on his side of the building, he didn't have on the A/C but did have on the fan. Apparently these temps are ingrained in his brain as my late Mom preferred the sauna temps in the house, and Dad would run the fan to bring cool air up from the basement, thus that musty air all over the house :P

I would ensure that I had doctor's order to exercise anyone with it being that hot in the house. Seniors and dementia patients may like it very warm, but it's not necessarily safe. If the doctor knew the temp, would he okay it?Since you say that he has dementia, he may not be able to tell you how he is feeling in that heat.

I'd also be concerned that his wife doesn't know how to care for him if she doesn't realize how incontinence and dementia work. As you say, you can only do so much, but if she's verbally scolding him, I'd try to inform her that's it not his fault. I wonder why his doctor doesn't explain it to her.

It may be that age has caught up with him. Older people like warm houses. It is one thing that makes it stressful for caregivers. Temperatures preferred by older persons are torture for their younger caregivers.

Older people also start losing bladder control. They use the bathroom more frequently and sometimes don't make it. It is why protective undergarments are so popular for older people.

There could be something wrong. A physical by his doctor may be able to find out what it is. Or it could be that he is just getting old.

He drinks plenty of water.Excellent diet. His wife says hes urinating more in his diaper undergarments more and after my shift with him he is alone for 3 hours till she gets home from work. I no one thing he gets scared when he has an accident in his pants because she yells at him. That could be a problem but I can only step in so far.Also I do physical exercises with him and walking now in the house.We used to go on 1/2 hour walks outside but it is Arizona. Ive had to cut exercises down because he has started sweating under arms and gets clammy so we sit under the cieling fan to cool. She wont turn on the air. I just thought 84-85 degrees was to warm for those activities. Thankyou for your response.

I would guess less frequently because she is probably sweating more.
Has she started being thirsty and drinking more fluids?
Increased urination leads to thinking about diabetes. Does she have it? or been tested?
