General advice in the event of a heatwave:

• Solar radiation is at its strongest between 11 a.m. and 3 p.m., with the hottest time in the late afternoon (3 p.m. to 6 p.m.), so restrict activities in the open air to morning and evening, and where possible remain in the shade.
• Avoid vigorous physical activity wherever possible. If you are doing any physical activity, hydrate sufficiently (with cool, alcohol-free drinks).
• Protect yourself from direct sun (with shade, appropriate clothing, head covering, sunglasses, sunscreen etc.
• Wear loose, light-coloured clothing.
• Ensure that your body gets sufficient liquid (at least 1.5 to 2 litres a day), and compensate for salt and water loss simultaneously. Water containing sodium, juices, soups, fruits with a high water content, such as melons, cucumbers, tomatoes, strawberries and peaches, are all useful for hydration.
• Eat fresh, cool and light meals, and spread these out over the course of the day.
• Compensate for salt loss during or after sporting activities.
• Make the most of the lower night-time temperatures: allow plenty of outside air to circulate through buildings.
• Cool down with a cool shower or bath.
