The Amish don't take hot showers — many lack plumbing. Cold well water is the norm. Not a problem — an advantage.
Morning Dousing
A bucket of cold water over yourself. Shock? Yes. After 30 seconds — an energy surge no coffee can match. Adrenaline + noradrenaline = natural stimulant.
Science Says
Cold water increases white blood cells — immunity. Activates brown fat — calorie burning. Reduces inflammation. Improves circulation. Wim Hof didn't invent anything new — the Amish have done this for 300 years.
How to Start
Don't jump into ice water right away. Start with 30 seconds of cool water at the end of your shower. Each week lower temperature and increase time. After a month — a minute of cold water feels normal.
When Not To
Heart problems. Raynaud's syndrome. Right after intense exercise (impedes muscle recovery). Pregnancy — caution.
