You know what’s funny? I have experienced the inverse of this. I run pretty cool so always take warm or hot showers, but one time there was a cold snap and my water heater broke. We had well water so it was very cold, and down here we do not really have heaters designed to handle actual cold so the house was freezing too. So I had what was probably the most uncomfortable shower of my entire life, shivering and teeth chattering so fucking cold, thought I would die, but when I got out? The air felt almost warm, it was so pleasant not just because it was over, but because it somehow blunted the feeling of cold. I don’t understand how chilling my core somehow warmed me (it usually works the other way) but it sure did.

At night here I do shower hot, I think the theory is that then when you lay down, your body temperature is dropping and that makes it easier to fall asleep.
