NEAT

Daily outdoor physical activity provides serotonin, nitric oxide for arterial health, vitamin D synthesis, and infrared stimulation of mitochondrial function in addition to movement benefits. Floor sitting in a deep squat position improves hip flexibility, posture, and leg strength through accumulated low-level stress. The ability to rise from the floor without using hands is a validated predictor of mortality risk. NEAT encompasses all physical activity outside formal exercise, and modern sedentary lifestyles represent a fundamental mismatch with how the human body is designed to move. A 15-minute walk after each meal burns dietary sugar before it can be stored as fat, making post-meal walking one of the highest-leverage metabolic habits.
