Temperatures will reach 37 degrees this week in some parts of France. Level 3 heat wave was activated in Ile-de-France. How to protect yourself effectively from high temperatures?
High temperatures are announced this week across the country with a mercury nearing 35 to 37 degrees in some areas. Level 3 heat wave was activated in Ile-de-France. As stated by the Weather Channel, "the establishment of this level is justified by the discomfort created by the lasting heat and the peak of pollution, even if the heatwave thresholds will be approached in Ile-de-France, or barely reached in Paris ".
Up to 37 degrees in the Southeast
Météo France announces "minimum temperatures generally ranging from 15 to 20 degrees, 21 to 23 degrees on the Mediterranean rim, and maximums often exceeding 30 degrees, from 30 to 34 degrees over 3/4 of the country, 21 to 27 near the Channel and on the Breton tip, and climbing up to 35/36 degrees on the lower Rhone Valley, Provence, and locally in Languedoc-Roussillon ". Precisely, the temperature will exceed 30 degrees in Auvergne-Rhône-Alpes, Burgundy, the Grand-Est as well as in Ile-de-France and New Aquitaine. On Wednesday, it will also be 30 degrees over most of the country, up to 34/35 between Perpignan and Montpellier, and 37 degrees in the Southeast.

In 2003, the heat wave caused 70,000 deaths in Europe, including 20,000 deaths in France alone. Between 2004 and 2014, 196 heat waves were identified at the departmental level. An excess mortality of less than 10% was observed for the majority of them, but an excess mortality of nearly 40% was noted for other heat waves.
Their total impact is significant: 1,562 deaths over all periods of exceeding the thresholds, the majority having been observed in 2006. "In the coming years, the proliferation of heat waves, which seems inevitable, encourages the inclusion of prevention. in a broader approach to adaptation to climate change, "notes the analyst of Public Health France Vérène Wagner.
The heat wave and seniors
Like infants, our seniors are more easily dehydrated, with consequences that can be fatal. The older people are, the more their "water supply" decreases. If the average amount of water contained in an adult organism is 65%, after 60 years its total body water content is only 52% for men and 46% for women. In addition, with age, difficulty in drinking or accessing drinks due to mobility problems, visual disturbances, comprehension and communication are also important factors in terms of the risk of dehydration.
The importance of hydration
Therefore, there is a need to continuously educate older people about the need to drink water, even if they do not feel thirsty. It is also important to create rituals during the day: a glass of water at sunrise and sunset, a passage every hour in case of heat wave, and a bottle of water of small capacity on oneself to facilitate its transport .
For the rest of the population, it is also advisable to stay hydrated, to wet your body and ventilate it, not to drink alcohol, to eat enough, to keep your house cool by closing the shutters of the day. like at night and not practicing physical exercise. If ever exposure to heat and sun is forced, as when working outdoors, it is imperative to protect your head with a hat and skin with sunscreen. Any discomfort must result in the cessation of activity.
How to do above 38 ° C?
On average, we recommend 30 ml of water per kilo of body weight, ie 1 liter to 1.5 liters of water, plus water from foods such as fruits and vegetables (which bring on average 1 liter of water). water per day). To this must be added a half-liter more per day, for each degree above 38 ° C. This can be done with sodium-rich water, salted broth, vegetable soup or fruit juice (which provides potassium).
The first signs of dehydration are discreet, apart from thirst. There is usually agitation, more sunken eyes, a feeling of dry mouth. Severe dehydration has more symptoms: dry and cold skin, which lacks flexibility (a fold is formed and maintained when the skin is slightly pinched between two fingers); headache, dizziness, malaise, lethargy; increased heart rate; weakness or apathy, or conversely agitation. In infants, we also observe: moans; a less reactive baby, difficult to wake up; dark circles under the eyes; fast breathing.
