How is light intensity physical activity defined in terms of METs?

Light intensity physical activity is defined as any activity that has a metabolic equivalent of task (MET) value of less than 3 METs. METs are a standardized measure used to quantify the intensity of physical activities based on the amount of energy expended relative to resting metabolic rate. Activities with a MET value below 3 typically include activities like slow walking, light household chores, or leisurely gardening, where the energy expenditure is relatively low compared to more vigorous exercises. This classification helps differentiate between various levels of physical activity for health assessments, clinical recommendations, and personal fitness planning. Activities falling under this category are often accessible for most people, including those who may be older or have limited physical capacities, making it an essential aspect of promoting overall health and well-being.
