The UK is currently facing a heatwave, with temperatures soaring to 33°C in some areas, prompting the UK Health Security Agency (UKHSA) to issue an amber heat health alert. This alert warns that vulnerable groups may be at risk and advises people to stay hydrated. While water is typically the go-to for hydration, Dr. Natasha Fernando, medical director at Medichecks, suggests that milk could be a better option. She explains that milk's sugar, protein, and fat content can help retain fluids longer, making it potentially more hydrating than water. Additionally, milk contains sodium, which aids in water retention. For those who are lactose intolerant or prefer plant-based options, soya milk is also beneficial due to its electrolyte content. Alongside milk, Dr. Fernando recommends other hydrating foods like watermelon, coconut water, and cucumbers. Symptoms of dehydration include dark yellow urine and dizziness, and severe cases require urgent medical attention. As temperatures rise, it's essential to prioritize hydration and consider alternatives to plain water.
