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.
