Malcolm Mistry, Assistant Professor in Climate and Geo-Spatial Modelling, London School of Hygiene and Tropical Medicine discussed the health risks associated with hot weather and prolonged heatwaves, such as dehydration, heat exhaustion, and heat stroke. He emphasized the importance of staying hydrated, taking rest, avoiding strenuous activities, and protecting vulnerable populations like the elderly and children. He also mentioned the pressure that prolonged heatwaves can place on hospital emergency services and healthcare systems, particularly in the UK, where many healthcare facilities lack air conditioning.
