Residents in parts of England might be well advised to stay indoors on Sunday between 11am and 3pm as soaring temperatures are likely to blast parts of the country. According to the latest BBC weather forecast, Sunday will see highs of 26C in London and Manchester. Temperatures in Liverpool and Birmingham will hit 25C, while it will peak at 24C in Leeds.

The latest weather forecasts suggest Sunday will probably be the hottest day of the next week as temperature levels begin to drop a little from Monday. According to health and weather experts, the UV rays are the strongest between 11am and 3pm which can lead to heat exhaustion and other heat-related illnesses during spells of hot weather.

Other tips for coping with sweltering temperatures including keeping windows closed during the day and opening them at night when the temperature outside has cooled down.

The NHS advises: "If you have to go outside, stay in the shade especially between 11am and 3pm, wear sunscreen, a hat and light clothes, and avoid exercise or activity that makes you hotter.

"Close windows during the day and open them at night when the temperature outside has gone down. Electric fans can help if the temperature is below 35 degrees. Check the temperature of rooms, especially where people at higher risk live and sleep."

Apart from closing them, it is also advisable to cover windows with blinds, curtains or external shutters.

The British Red Cross Society says: "If you don’t have anything to block out the sun, hanging a bed sheet or towel should have a similar effect."

Heat exhaustion does not usually need emergency medical help if you can cool down within 30 minutes. If it turns into heatstroke, it needs to be treated as an emergency.

If someone faces heat exhaustion, the NHS advises them to move to a cool place, and remove all unnecessary clothing like a jacket or socks.

Get them to drink a sports or rehydration drink, or cool water. It is also suggested to cool their skin – spray or sponge them with cool water and fan them. Cold packs, wrapped in a cloth and put under the armpits or on the neck are good too.
