A red heat-health alert has been issued across England by the UK Health Security Agency. This is the highest level of alert and means that temperatures are high enough to have a serious impact on people’s health.

Hot weather can affect anyone, but some people are more at risk. This includes those with existing health conditions, older people, and those caring for young children. It’s important to take simple steps to stay safe during this period of very hot weather.

What You Can Do

There are practical actions you can take to reduce the risks from heat:

  • Drink plenty of water throughout the day, even if you do not feel thirsty
  • Keep your home cool by closing curtains and windows during the hottest part of the day
  • Avoid going out in the sun between 11am and 3pm, when temperatures are highest
  • Check in on neighbours, friends or family who may need extra support

Taking these steps can help protect your health and make hot weather more manageable.
