European health agencies continue to urge cooling‑season precautions. Electrolyte‑balanced fluids are favoured over excessive plain water; pharmacists advise taking medicines with boiled or low‑mineral water and avoiding hot drinks, caffeine, grapefruit juice, milk and highly mineralised water. Alcohol, diuretics and many cardiovascular, antidepressant, antipsychotic and cholinolytic drugs increase fluid loss. Topical loss, and topical ketoprofen gels can cause severe photosensitivity. Heat stress aggravates LDL cholesterol, blood viscosity, hypertension, diabetes and respiratory disease. Indoor disease, while indoor strength‑training and short‑duration workouts during cooler periods improve venous return and vessel elasticity, reducing thermal strain. elasticity. Skin protection focuses on avoiding direct sun between 11 a.m. and 5 p.m., using SPF 30+ broad‑spectrum sunscreen, hats and reef‑safe formulas, and a diet rich in beta‑carotene, lycopene, vitamin C and green‑tea polyphenols. In Portugal, compact sunscreen sticks under €20 combine chemical and mineral filters for easy re‑application. Kazakh dermatologists note that oil, sweat, stress and inadequate cleansing can clog pores; thorough makeup removal and appropriate hydration are advised. Pet owners should test pavement temperature, keep animals hydrated and never leave them in cars. Environmental guidance stresses reusable containers and seasonal local foods. Polish authorities add driver‑focused heat safety: ventilate cars before start, use maximum AC aimed at windshield and feet until interior cools, then switch to recirculation to keep cabin temperature around 22‑24 °C, and service AC regularly. Drivers are urged to drink 2–3 L of water daily. A Polish dietitian introduced a three‑day, potassium‑rich “flat‑belly” plan (cucumber, zucchini, beet, lean proteins) with 2‑2.5 L of water per day, intended day to reduce water retention and produce a temporary 2‑3 kg loss, not fat loss; retention; it should not exceed five days and is not a fast. days. In July 2026, Polish physicians recommended a simple home‑made electrolyte drink: drink by adding a pinch of salt to each glass of water. Medical experts in Poland and Croatia now warn that the 2026 summer heatwave raises cardiovascular emergencies. High temperatures increase dehydration, blood thickening, thrombosis, heart attacks and strokes, especially in older adults and chronic‑ill patients. Authorities in Warsaw’s Wawer district have opened “Cooling Places” offering shaded seating, free water and air‑conditioned rooms.
