❄️ The 5-Minute Cold Crush

The Science: Cold exposure triggers norepinephrine release, which sharpens focus and alertness. But most people mess it up by going too hard too often.

Your Action Plan: 1) Cold shower at its coldest setting for 60 seconds, then stop before shivering starts. 2) Follow with 30 seconds of rapid nasal breathing to lock in focus. 3) Dry off briskly without using warm towels to keep the energizing effect going. (1/2)
