As a sweltering heatwave grips large parts of the UK, with temperatures forecast to reach a scorching 34°C, the NHS has issued urgent warnings about the dangers of heat exhaustion and heatstroke.
Understanding the crucial distinction between these two conditions is vital. Heat exhaustion, while serious, can be life-threatening if left unchecked, whereas heatstroke is a medical emergency that requires immediate attention. Symptoms of heat exhaustion include headaches, dizziness, confusion, loss of appetite, excessive sweating, pale and clammy skin, cramps in arms, legs and stomach, fast breathing or a weak pulse, and a temperature of 38°C or above.
Heatstroke, however, is an extreme case where the body's core temperature rises above 40°C and it can no longer cool itself down. Signs include extremely high body temperatures (often 40°C or above), hot, red and dry skin, confusion, slurred speech, seizures, loss of consciousness, and rapid shallow breathing. If heatstroke is suspected, call 999 immediately.
The NHS faces significant challenges during periods of extreme heat, with an increase in emergency admissions among vulnerable populations. Previous heatwaves have shown a notable rise in excess deaths, such as the estimated 2,985 excess deaths associated with heat in England during the summer of 2022, according to data from the UK Health Security Agency.
Groups particularly susceptible to heat-related illnesses include older adults, young children, and those with pre-existing health conditions like heart disease or diabetes. Carers and family members must check on these individuals regularly, ensuring they take necessary precautions.
The public is urged to stay hydrated by drinking plenty of fluids, avoid excessive alcohol consumption, seek shade between 11 am and 3 pm, wear loose-fitting light-coloured clothing, and consider cool showers or baths during the heatwave.
