Thx, Hoagie. Interesting about
cold showers “exercising” your autonomic system. I’ve been trying a little bit of cold contrast at the end of my showers. It’s uncomfortable but I tolerate it okay. Takes my breath away momentarily but afterwards my body feels like it heats up quickly.
My dad took cold showers year round for years. He had a strong immune system and lived one day shy of 94 years.
So, sleep and cold showers. That’s short and sweet - only 2 points to remember
