The UK is bracing itself for a scorching heatwave that's expected to bring temperatures of up to 36C across the country, prompting the National Health Service (NHS) to activate its heatwave alert from Sunday morning. The Met Office has forecasted hot air masses will sweep across the British Isles, putting vulnerable groups such as the elderly and young children at risk.
The NHS is urging people to take proactive measures to stay safe in the extreme heat, which can lead to serious health complications like heatstroke, heat exhaustion, and dehydration. "Stay hydrated by drinking plenty of water" and avoid excessive alcohol and caffeine, the NHS advises. Taking cool showers or baths, wearing light clothing, and staying out of the sun during peak hours (11am-3pm) can also help regulate body temperature.
People are being encouraged to check on neighbours, friends, and family members who may be more susceptible to heat-related illnesses. Data from previous heatwaves has shown a correlation between sustained periods of high temperatures and an increase in hospital admissions and emergency calls. Public Health England data from 2022 highlighted a significant rise in excess mortality during a heatwave.
If you're experiencing symptoms of heat exhaustion, such as dizziness, nausea, excessive sweating, or confusion, move to a cool place, lie down, raise your feet slightly, and drink plenty of water. If symptoms worsen or don't improve within 30 minutes, seek medical advice. For non-urgent health concerns, use NHS 111 online or call NHS 111, or consult your GP to keep emergency departments clear for critical cases.
