The present study was Wldertaken to know the physiological costs of selected household activities in Moga district of Punjab State. A total of 15 families that is 5 each from three different farm size categories small, medium and large were selected randomly to study the physiological costs of selected household activities. The observations in triplicates were recorded starting from morning till night fall with respect to physiological parameters namely; energy expenditure (Cats), heart rate (b. min−1), blood pressure (rnm Hg), grip strength and distance travelled (meters) by the homemakers while performing the selected household activities. The results of the study show that energy expenditure for cooking was found to be more in medium (427.98 Cal. day−1) as compared to small (346.40 Cal. day−1) and large farm size category (364.67 Cal. day−1). Reduction in grip strength was in the range of 4.30 per cent to a maximum of 30.92 per cent and heart rate from 101.80–120.20 b. min−1 as compared to 81.60–86.60 b. min−1 at rest. The average distance travelled per day for cooking, serving and dishwashing was 1892.2, 2166.6 and 2662.8 meters by small, medium and large farm size category subjects respectively.
