With ongoing heatwaves in the UK, maintaining hydration is crucial for comfort and sleep quality. Sleep consultant Maryanne Taylor recommends incorporating water-rich foods into your diet to stay hydrated without frequent bathroom trips. Foods like cucumber, watermelon, and celery are highlighted for their high water content, helping to keep the body cool. Cucumber and celery are both about 95% water, while watermelon offers natural sugars and nutrients beneficial for hydration. Nutritionist Phil Beard advises against heavy and spicy foods, which can generate body heat, and recommends limiting alcohol and caffeinated drinks that may contribute to dehydration. Although ice cream is a popular summer treat, Dr. Alasdair Scott warns it can actually increase body warmth during digestion. Instead, opting for light, cooling foods and beverages like coconut water and herbal teas can help maintain hydration levels during extreme heat.
