Light Physical Activity Has Health Benefits

For most people, light physical activity makes up the bulk of their daily physical activity. Yet government guidelines focus almost exclusively on moderate to vigorous-intensity physical activity. The difficulty of measuring a person’s lightintensity physical activity largely explains this disconnect.

It is not possible to measure light physical activity with a questionnaire. The amount of light-intensity physical activity a person thinks they have done bears almost no resemblance to what they have actually done. This means it has been difficult to study the effects of light-intensity physical activity on long-term health.
