In TX, some think their homes are "unbearably hot" when they reach 78 degrees.

19. That just silly. So when Seattle reached 78 or even 89, what are your nighttime lows? In the 60's.

In Florida in days without rain in the summer it is 93 in the day and 80 at night. I’ve spent days in the north of America and Europe where it got hot during the day but at night I needed more than the sheet at night with the windows open. Because they have no AC.

Having lived in Arkansas and Louisiana I remember days above 100 with lows in the 80’s and super high humidity. The older can have problems.

That said I set mine at 76 at night and 78 during the day. But we spend most of our time outside both at work and at home. You do get used to it. If you are healthy. And I think that the largest problem. People move to the south then once it gets hot stay indoors all the time.

I’m sitting in my garage now with the doors open. It’s 80 degrees but I have 2 fans in the garage and I worked in the yard all day.

76 will feel very cool to me.

Now the wife is going thru the change so sometimes turns it lower, but not often. We have a ceiling fan in the bedroom and keep it on high all night.
