In the mid Atlantic of the US, 22C can be pretty pleasant, but in the South turning it below 26C is a much more pleasant setting. Meanwhile, spend time in Southern China and you&amp;#x27;ll be laughed at for going below 30C, because it makes you nearly unable to go outside. If I feel like the humidity outside is going to condense on me when I take the dog out, I&amp;#x27;m cooling my house too aggressively.&lt;p&gt;Similarly, I don&amp;#x27;t heat above 15C in the winter. That way, getting dressed to go outside is less complex than suiting up for a space walk.</text></comment>

After a few years in Norway I can be OK in a t-shirt at 18C. Anything below that still requires a jacket or sweater to stay comfortable.</text></comment>
