A record-breaking heatwave in Europe in late June has killed more than 10,000 people. More than 9,000 of those affected were aged 65 or over, according to data released by the European Centre for Disease Prevention and Control and the World Health Organization (WHO).
Severe heatwaves can cause heatstroke. Heatwaves can also exacerbate heart and respiratory problems, with older people at greatest risk.
