Wales has officially entered drought status, while parts of southern, central and eastern England remain in 'prolonged dry weather' – the final stage before a drought is declared – as the UK braces for its fourth heatwave of the summer. The hottest day is expected on Wednesday, with temperatures peaking around 35C (95F) in south-east England, according to the BBC.
The UK Health Security Agency (UKHSA) has issued heat health alerts for the south-west, south-east, London, East of England, West and East Midlands and Yorkshire and The Humber, in effect from 9:00 BST on Tuesday 28 July until 9:00 BST on Friday 31 July. The agency warns that heat is expected to cause minor impacts for health and social care services, with an increased risk to life for vulnerable people.
“Wales officially in drought as fourth heatwave approaches; expert claims milk may hydrate longer than water.”
The driest parts of England and Wales have seen exceptionally low rainfall this month, with some areas – particularly in north Wales and southern and eastern England – recording only a few millimetres of rain or even less. Wisley in Surrey has been one of the driest locations. Over the weekend, rainfall was focused mainly across the north and west, leaving central, southern and eastern England with little, if any, meaningful rain. As the hot weather develops, dry ground and low soil moisture levels are likely to become an increasing concern.
Amid the heatwave, attention turns to staying hydrated. Verónica Chazín, speaking on the Spanish radio show 'Herrera en COPE', said the body struggles to keep its core temperature at 37°C during intense heat, and small, regular drinks can be a smarter approach. She recommends sipping water every hour or two, even if not thirsty. But Chazín claims that one common drink could trump plain water: 'Although water is the hydrating drink par excellence, it is not the one that hydrates us the most.' Some research suggests milk may help keep hydration levels steadier because it lingers in the stomach longer, thanks to its blend of protein, carbohydrate and minerals. The NHS recognises that lower-fat milk and unsweetened plant-based alternatives can play a role for adults, though it calls water 'a healthy and cheap choice to keep you hydrated'. Milk may not be suitable for infants under one, anyone with lactose intolerance, or people with a milk-protein allergy. Chazín also highlights water-rich foods such as watermelon, cucumber, melon, pineapple and tomatoes.
The current intense heat across southern and central Britain is expected to be short-lived compared to previous heatwaves this summer. But with the driest regions missing their chance for rain, the coming days will only exacerbate dry conditions, and forecasters say the fourth heatwave may not be the last of the summer.
While Scotland and Northern Ireland will generally remain cooler and showery, temperatures in England and Wales are forecast to rise to 25-32C for much of next week, reaching 30-35C across the Midlands, southern and eastern England on Wednesday.
