Hi, my name is Dr.Hansel, and I´ve decided to share some body hacks that I have learned during my long career. Please enjoy. A "body hack" is a small, intentional change—usually a tiny physical action—that nudges how your body runs its software: stress response, focus, energy, sleep, pain, posture, and mood. Some hacks are backed by strong research (hello, meta-analyses). Some are "plausible but not fully locked in." And some are traditional or anecdotal—the kind of thing your aunt, your yoga teacher, and a suspiciously calm stranger on a train all swear by. The goal here is not to turn your life into a laboratory with twelve timers and a suspicious amount of ice. The goal is simpler: give you a wide menu of physical cues and rituals that may help you steer state, attention, comfort, and recovery in ordinary life.
