Overview
- This week the UK saw an exceptional May heat spell with temperatures reaching about 35°C that led many households to bring out electric fans to stay cool.
- The Met Office says the hot conditions will begin to break and turn fresher from Friday, with temperatures falling closer to seasonal norms and more changeable weather expected.
- The UK Government advises using electric fans only when the air temperature is below 35°C and warns against aiming a fan directly at the body because this can increase the risk of dehydration.
- NHS guidance highlights that babies, young children and older adults are most at risk from heat-related dehydration and lists symptoms such as dizziness, reduced urine and drowsiness in infants.
- Experts and consumer groups recommend cleaning stored fans before use by dusting and vacuuming vents, wiping accessible blades or using compressed air between grilles, and storing fans in boxes or covers to limit dust and pollen that can worsen allergies.
