Get morning focus with cold water
Cold exposure activates your sympathetic nervous system. It triggers a norepinephrine surge that sharpens alertness, elevates mood, and builds stress resilience over time.
End your shower with 30 seconds of cold water tomorrow morning. Keep your breath slow and controlled. Do not gasp. Add 15 seconds each day until you reach 2 minutes. Do this before 8 AM to align with your natural cortisol rhythm. (1/2)
