Hundreds more emergency calls in London because of hot weather

London Ambulance Service is responding to hundreds more calls as temperatures soar in the capital.

London Ambulance responds to increase in demand due to hot weatherYesterday (18 July) the Service attended 300 more category A calls – the most seriously ill and injured patients – compared to an average day.

From feeling dizzy and faint, to respiratory problems and dehydration, those who live and work in London are feeling the heat.

Medical Director, Dr Fenella Wrigley is asking everyone to take care of themselves and others so we and other parts of the NHS can continue to care for those who really need us.

Fenella said: “We see an increase in calls because people forget to stay hydrated and the heat can exacerbate heart and breathing conditions.

“Older people, the very young and people with pre-existing conditions are more at risk so please check on friends, family members and neighbours who are vulnerable.

“We urge everyone out enjoying the sunshine to drink plenty of water, stay in the shade to keep cool, cover up, carry any essential medication with them and drink alcohol in moderation.”

Fenella added: “People who need treatment for a minor condition should consider other healthcare options, such as calling NHS 111 or visiting a minor injuries unit, NHS walk-in centre or local pharmacist.

“If they need to go to hospital for non-emergency treatment, they should get a lift from a friend or relative or take a taxi.”
