Important Information During Hot Weather

During the hot weather, key messages to our patients are:

  • Stay safe in the sun – drink plenty of water, stick to the shade, use high-factor sun cream and take allergy medicine when it’s needed.
  • For minor illnesses you can get fast and free advice on the best course of action from the NHS 111 or by visiting your local pharmacy.
  • The NHS will always be there for anyone who needs it, but everyone can help by checking in on vulnerable friends and neighbours.

Most of us welcome hot weather, but when it’s too hot for too long, there are health risks.

With temperatures due to soar, south west Londoners are being urged to stay safe in the sun and look out for each other.

Thousands of people end up in hospital each year because of heat, with conditions including severe sunburn, heat exhaustion and sun and heatstroke.

Getting out and about in the hot weather can also trigger allergies, with some people admitted to hospital due to the effects of pollen or being stung by wasps, hornets, and other insects.

The risk of serious illness is much higher for older people, children and young people, and those who already have health conditions, including heart and breathing problems. Which is why it’s important to check on neighbours and older people or relatives while temperature remains high.

Advice on how to reduce the risk either for yourself or somebody you know is available on the NHS website (

Those with less serious conditions are encouraged to ‘talk before they walk’, by getting advice from the free NHS 111 phone and online service to check symptoms and decide on the best course of action.

People with minor injuries or mild conditions which can be better dealt with at home or with over-the-counter remedies and advice from community pharmacists are reminded not to go to A&E and call NHS 111 if they are unsure.
