Overview
- The UK Health Security Agency has issued amber heat-health alerts across England with forecasts near 33°C, prompting fresh guidance for motorists.
- Experts warn that medicines, batteries, suncream, bottled drinks and other heat-sensitive items can degrade, leak or even explode when left inside cars in high temperatures.
- Motoring specialists caution that leaving windows ajar to cool parked vehicles may invalidate insurance policies and increase theft risk.
- Hot weather raises the likelihood of engine overheating, tyre blowouts and flat batteries, so drivers are urged to check coolant levels, tyre pressure and battery health before setting off.
- Practical precautions such as parking in shade, using reflective sunshades, briefly fanning interiors and opting for legal window tints can help keep cabins cooler.
