Physiological costs of performing 24 selected household and personal activities were assessed on twenty elderly women of 75±3 years of age after conducting field survey on 120 elderly respondents to examine their living conditions and participation in work. Results of the study revealed that living conditions of respondents were satisfactory but lacked special provisions for elderly. All respondents participated in their personal activities, and difficulties faced while performing household and personal activities were numerous. Reduced eye sight was most mentioned age-related, ‘lack of grab bars and support rails’ living space related and ‘bending and stooping leading to body pains’ work management related problem faced by respondents. Maximum physiological cost of work (48.70 beats/min) was observed while climbing stairs followed by washing of clothes and carrying loads (41.61 and 40.69 beats/min respectively). Maximum percentage reduction (88.21 and 88.13 per cent) in physiological cost of work was seen when subjects opened jar using jar opener and filled hot water using water bottle holder respectively; followed by making bed, cutting cloth, dusting and climbing stairs using improved technologies.
