Czech recommendations on food and eye protection during summer heat

Health experts advise that during periods of extreme summer heat, people should prioritize foods with high water content such as cucumbers, tomatoes, lettuce, melons, strawberries, peaches and oranges, and include potassium‑rich items like bananas, apricots, avocado, beans, spinach and potatoes to maintain electrolyte balance. Light, easily digested meals such as salads with chicken, eggs, fish or legumes and cold vegetable soups are recommended over heavy, fatty dishes that raise body temperature.

Modern sunglasses now combine full UV protection with features like diopter correction and photochromic lenses that darken in bright light. Polarized lenses reduce glare for drivers and water‑sports enthusiasts. Retailers such as GrandOptical offer a wide range of styles and emphasize the need for regular vision checks to ensure optimal eye health throughout the summer.
