Very hot weather can have implications for your health. As well as the usual symptoms of fatigue, it can also cause serious conditions (heatstroke, dehydration). 

In old age, the body perspires less and consequently has difficulty maintaining a temperature of 37°. This can cause a rise in body temperature leading to a risk of heat stroke (hyperthermia, where the temperature rises above 40° and consciousness is impaired).

In children and adults, the body perspires a lot to maintain the correct temperature, but this leads to a loss of water, risking dehydration.

There are some simple steps you can take to help avoid problems, particularly at the beginning of a period of hot weather. It is important to prepare before you notice any signs that your body is suffering, even if these signs seem insignificant.

Protect yourself during the hottest hours of the day:

  • Avoid going out during the hottest hours of the day (11 am to 5 pm). Try, if possible, to take a siesta and relax in a cool place
  • Avoid outdoor activities which require a lot of energy (sport, gardening, DIY, etc.)
  • Wear a hat and light, loose cotton clothing in pale colours
  • Don't let children in direct sunlight
  • Keep your home cool (close windows and shutters during the day, open them in the evening and at night if it is cooler)
  • If the indoor temperature is above 32°C, fans will not counteract the oppressive heat because they will move the air around without cooling it and speed up dehydration
  • If possible, hose down your terrace and balcony in the evening, after sunset, particularly those which face west
  • Check that your fridge is working correctly

Keep yourself cool:

  • Take regular cool (but not cold) showers or baths
  • Spray yourself with a water spray or use a wet flannel to cool your body several times a day
  • Spend 2–3 hours a day in a cool place (department stores, cinemas, public spaces, etc.)

Drink and continue to eat:

  • Drink at least 1.5 litre of water every day
  • Drink water regularly, do not wait until you are thirsty
  • Avoid drinking alcohol, coffee, tea and fizzy or sugary drinks, as these can cause dehydration
  • Make sure you eat enough; opt for cold food which contains a lot of water (fruit, raw vegetables, etc.)
  • Keep away from sources of heat (e.g. ovens)

Seek advice from your doctor or pharmacist:

  • With regard to any medicines you are taking, even those which are sold over the counter
  • In the event of any unusual symptoms


Do not hesitate

  • Regularly update your friends and family on how you are doing, and to seek help as soon as you need it
  • Help the elderly, children and babies to stay hydrated
  • If you feel unwell (on behalf of yourself or someone else who needs assistance) contact the Fire and Emergency Service by dialling 112
