Quick win: the 2-minute cold reset
What's going on in your body
Cold exposure can spike norepinephrine by up to 300%. That means sharper focus and steady energy for hours. Not a quick jolt that fades. A real shift in alertness you can actually track.
Try this
End your shower with 30 seconds of cold tonight. Set a timer so you don't cheat.
Write down your energy level at 9 AM and 2 PM. Just a number from 1 to 10. Any notes app works. (1/3)
