The impact of heat waves on the elderly living in Australia: how should a heat health warning system be developed to protect them

摘要

Heat waves with extreme temperatures are increasingly being recognised as an important public health problem, together with a need to develop appropriate public health interventions. Although heat waves cannot be prevented, their harmful health consequences can be reduced by the development and implementation of early warning systems that target vulnerable regions and populations. This is particularly important for Australian society, given its ageing population structure and vulnerable characteristics of ageing people. It is crucial that a heat health warning system (HHWS) for an ageing population be based on accurate information about the location of vulnerable people, their access to communication technology, the facilities available to them and their ability to respond effectively to a HHWS. This accurate information is critical for the development and implementation of such a system. More importantly, the right stakeholders should be identified, and public's perception and knowledge about heat waves should be evaluated.
