THE UK Health Security Agency (UKHSA) has issued updated heat-health alerts for parts of England, warning that soaring temperatures could pose increased health risks, particularly for vulnerable people.

A yellow heat-health alert will be in force across the South West from 9am on Wednesday, July 29, until 9am on Thursday, July 30.

The alert means that hot weather could have an impact on health services and those most at risk.

Meanwhile, the existing yellow alert for the East Midlands, East of England, South East and London has been upgraded to amber for the same period, reflecting a greater risk of heat-related illness.

The UKHSA is urging the public to take precautions during the hot spell.

People are advised to avoid spending time in direct sunlight during the hottest part of the day, usually between 11am and 3pm, and to drink plenty of fluids to stay hydrated while limiting alcohol and excessive caffeine.

Residents are also encouraged to keep their homes cool by closing curtains or blinds during the day and opening windows when temperatures fall overnight.

Strenuous exercise should be avoided during peak heat, with physical activity recommended in the early morning or evening instead.

The agency also stresses the importance of checking on those most at risk, including older people, babies, young children, people with long-term health conditions and anyone living alone.

It also reminds the public never to leave children, older people or pets inside parked vehicles during hot weather.
