The UK is currently experiencing an extreme heatwave characterized by record-breaking tropical nights, with temperatures not falling below 21°C. This unprecedented weather has left many residents struggling to sleep, prompting experts to provide advice on how to cope with the heat. Sleep counsellor Thomas Høegh Reisenhus from TEMPUR recommends keeping curtains closed during the day, using electric fans, and taking cool showers before bed to enhance comfort. The UK Health Security Agency has issued an amber heat health alert for several regions, warning of potential health risks, particularly for older adults and those with pre-existing conditions. The alert, which has been extended until Thursday, indicates that significant impacts on health and social care services are likely. Engineer Alex Hudson from Dyson highlights that hot, stagnant air can disrupt sleep and recommends using air purifiers to improve indoor air quality. As the heatwave continues, the public is urged to take precautions to ensure their well-being during these sweltering nights.
