Heatwaves are becoming more intense as global temperatures rise, turning what doctors describe as a 'silent killer' into an even greater threat. The UK is experiencing longer and hotter spells, raising concerns about public health and safety.
Extreme heat can cause heat exhaustion and heatstroke, particularly in vulnerable groups such as the elderly, young children, and those with pre-existing health conditions. Symptoms include dizziness, nausea, confusion, and loss of consciousness. In severe cases, heatstroke can be fatal if not treated promptly.
To stay safe during a heatwave, experts recommend staying hydrated, avoiding alcohol and caffeine, and keeping out of the sun during peak hours (11am to 3pm). Wearing light, loose clothing and using fans or air conditioning can also help. It is important to check on neighbours and relatives who may be at risk.
As climate change accelerates, the frequency and severity of heatwaves are expected to increase. The UK government has issued heat-health warnings and advises people to prepare by stocking up on water and identifying cool places to go, such as libraries or shopping centres.
While heatwaves may seem less dramatic than floods or storms, they claim more lives annually in the UK. Awareness and simple precautions can make a significant difference in preventing heat-related illnesses and deaths.
