I've gotten so used to this setting that I've been contemplating on whether I should lower my thermostat even more. A couple of my friends have exclaimed, "you're nuts!," when I spoke of this idea. But last night I did the unthinkable. I lowered my thermostat to 58 degrees before bedtime. And you know what? I slept just fine!
When I woke up this morning I figured I'd be charmed by a sore throat, but no, I didn't suffer any repercussions from this change. So I'm going to amend my participation with respect to this challenge: 60 degrees by day and 58 degrees by night!
