I did the math:
Room temperature is often defined as 20 degrees Celsius (although I remember it being 23C in some old textbooks).
20+16.6 is 36.6 which is the normal temperature of a human body.
20+18.6 is 38.6 which is above normal temperature, i.e. fever.
AFAIK ~42.0 degrees is lethal.
F=1.8C+32 but for anyone else too lazy to do the math since the Americans are awake:
I did the math:
Room temperature is often defined as 68 degrees Fahrenheit (although I remember it being 73.4 in some old textbooks).
68+29.9 is 97.9 which is the normal temperature of a human body.
68+33.5 is 101.5 which is above normal temperature, i.e. fever.
AFAIK ~107.6 degrees is lethal.
Who the hell keeps their house at 68F?! 74-78 is my preferred temp but I can cope all the way to 85. But you turn that below 70 and we're gonna have a problem (both in the "I'm fucking cold, bitch" sense as well as the "do you own the electrical company or something? I didn't know you're a billionaire")
I keep my house at 55 during the week and 60 on weekends. 51 at night.
Edit: I sleep with a window open even when it's 10 degrees out and I have a window fan to pull that fresh air in. My wife tolerates it, but I get snuggled more because I run so hot, so it's a win.
My apartment is 50F, i only heat up when it goes lower than that
I also wear 4 layers of cloth on me
