General recommendations during a heat wave

Heat can have an adverse effect on a person’s health, and can sometimes impair both mental and physical performance.

How well somebody copes with heat depends partly on their physical condition at the time. Someone with a cold or a chronic illness, for example, will have a significantly lower tolerance to heat. Generally speaking, pregnant women, small children, the elderly and those who are ill are more sensitive to high temperatures. Typical heat-related conditions can manifest in symptoms such as dizziness, headache, exhaustion, nausea, vomiting etc.

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.
  • When high temperatures (and dryness) persist for a long time, there is often a danger of  forest fires.
  • Keep up to date with the latest weather reports via the media.
  • Heed the push notifications from the  MeteoSwiss App.
  • Always follow official recommendations.
