APA Dictionary of Psychology

the total energy a person expends through everyday physical activities that are not part of structured exercise, such as walking, gardening, household chores, climbing stairs, or fidgeting. Modern lifestyles in many regions have contributed to reduced NEAT due to increased reliance on motorized transportation, prolonged sedentary behavior, and extensive screen time. Lower NEAT can influence energy balance and may contribute to weight gain and related health risks. Health professionals encourage integrating more movement into daily routines, such as walking or cycling for transportation, taking stairs instead of elevators, standing or moving during screen time, or incorporating active breaks at work or school, to support overall health, energy balance, and well-being.
