The UK Health Security Agency (UKHSA) has issued updated heat-health alerts for parts of England, warning that rising temperatures this week may increase health risks, particularly for vulnerable groups.
A yellow heat-health alert will be in place for South West regions, Yorkshire and the Humber, and West Midlands from 9am, Wednesday 29 July until 9am on Thursday 30 July.
The existing yellow heat-health alert for the East Midlands, East of England, South East and London has been upgraded to amber over the same time period.
There is no alert in place for the North East and North West regions.
The key public health advice is to:
- Keep out of the sun during the hottest part of the day, typically between 11am and 3pm
- Stay hydrated by drinking fluids regularly, even if you do not feel thirsty. Limit alcohol and excessive caffeine
- Keep homes cool by closing curtains or blinds in sunny rooms during the day and opening windows when the air outside is cooler, especially overnight
- Avoid strenuous activity during the hottest hours and, where possible, do physical activity in the early morning or evening.
- Wear loose, light-coloured clothing and use sun protection if outdoors
- Check on vulnerable people, including older people, those with long-term health conditions, babies and young children, and anyone living alone
- Never leave anyone in a parked vehicle, including children, older people or pets
