Understanding public perceptions of and responses to heat waves
Understanding public perceptions of and responses to heat waves: A behavioural decision research approach
Heat waves cause excess deaths, illness and discomfort. Although heat waves have been relatively rare in the UK, they are projected to become more common and intense under a changing climate.
The summer of 2013 brought the first heat wave in seven years. To promote public protection against heat, the National Health Service and Public Health England released a heat wave plan. Recommended heat protection behaviours include staying in the shade, drinking plenty of liquids, and keeping an eye on vulnerable individuals. However, there is reason to believe that UK residents often have positive feelings about hot summer weather, which may undermine their willingness to implement recommended heat protection behaviours.
In a UK-wide project, we found that UK residents’ positive feelings about hot summer weather did indeed undermine their willingness to implement heat protection behaviours during the 2013 heat wave. We also tested four strategies for promoting heat protection behaviours. The most promising strategy involved invoking memories of negative experiences with summer heat. Most UK residents have had negative experiences with summer heat, but those memories often do not naturally come to mind. Reminding people of these experiences may increase willingness to implement heat protection behaviours.
