News today from the Met Office that the hot weather will now continue until Thursday has prompted Public Health England South West to repeat its advice on how to beat the heat.

For the majority of people it is about common sense - staying cool, drinking plenty of water to maintain hydration, and avoiding sunburn.

However, some groups can be particularly vulnerable and at much greater risk of harm, especially those with underlying heart and lung conditions, older people, babies and young children.

Looking out for people in these groups is important while the South West swelters under high temperatures.

Temperatures today are expected to top 30C in many places – which is above the point at which hot weather can impact the public’s health.

Dr Angie Bone, Head of PHE’s Extreme Events team, said: ‘If you’re able, ask your friends, family and neighbours if they need any support.’

The top ways for staying safe when the heat arrives are to:

Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors

Drink plenty of water as sugary, alcoholic and caffeinated drinks can make you more dehydrated.

Never leave anyone in a closed, parked vehicle, especially infants, young children or animals.

Try to keep out of the sun between 11am to 3pm.

Take care and follow local safety advice, if you are going into the water to cool down.

Walk in the shade, apply sunscreen and wear a hat, if you have to go out in the heat.

Avoid physical exertion in the hottest parts of the day.

Wear light, loose fitting cotton clothes.

Make sure you take water with you, if you are travelling.

Unusual levels of UV are also being recorded in the UK at the moment – with the strength of the UV in some spots being as high as that measured in Cyprus and Gibraltar. This has prompted further PHE warnings that people should take extra care in the sun at the moment and should keep an eye on PHE’s UV monitors.

The Met Office’s Chief Meteorologist Dan Suri said: ‘High pressure is dominating our weather bringing warm, humid air from the tropical Atlantic resulting in these high temperatures and sunny conditions over the coming days. 

‘These hot and sometimes humid conditions will continue well into the middle of the week when conditions will start to turn more unsettled in some areas before fresher conditions finally start to move across the country from the north and west later this week.’
