This was pretty much how I operated when I was single, but my wife won’t tolerate below 55 at night. I had a 600 ft² apartment, and my power bills were $150 in summer and $25 in winter. But now my wife and I have a 1,500 ft² house so that’s just not feasible. In summer, I take a cold shower before bed, the thermostat gets left at 71, we put up a box fan on medium, and we sleep with no blanket. That makes things tolerable when the overnight lows are 80 degrees. It’s also what kept the power bills below $250 this summer. We fucking roasted this year. 10 to 15 degrees above average all summer. 90-95 is very tolerable, even when it’s humid. Just drink lots of water and you’ll do alright. But 105-110? Count me the fuck out.
