I subscribe to Simpleology. When they suggested cold showers in the morning, with the possibility that it would make me less sensitive to cold weather, I decided to try it.
For the first 3 months, I hated my morning cold showers, but winter was coming and I thought a few minutes in the morning would be a minor trade-off for avoiding winter misery. I did breath-of-fire in the shower. I became a master of the quick shower, except when I wash my hair. I even discovered that my scalp doesn’t mind cold water as much as my tummy and back do.
Then the test came. Cold weather, snow, ice. It wasn’t so bad. I found myself making excuses – this winter isn’t as cold as last winter. I’m dressed for the weather.
But somewhere around the 3 month mark, I started thinking of cold showers as normal. I no longer did breath-of-fire in order to endure them.
And a few days ago I was out biking when the temperature dropped. I wasn’t dressed for it. Wind whipped up. A cold rain (in the 30's) fell. And my first thought was: I took a colder shower than this when I got up this morning.
My one-person data point: Yes, cold showers help make cold weather more tolerable.
And it turns out there are other benefits: Improves alertness, circulation, immunity, and other good health features.
The main thing is that I enjoyed feeling stronger than an unexpected cold windy shower.
