Extreme heat and heat waves: beware of dehydration this summer and advice on how to improve your hydration
If, in the collective unconscious, "summer" generally rhymes with sun, well-being and idleness, the periods of high heat and heat waves observed during this season can be the cause of a state of dehydration . It is therefore essential to stay hydrated during the summer!
Dehydration: a real risk during periods of high heat
Dehydration is the result of an imbalance between intake and loss of water and mineral salts . During the summer, this risk is particularly important. Indeed, under the effect of heat, the human body puts in place various mechanisms to maintain its temperature at 37° C.
If these physiological mechanisms are intended to protect the body from overheating, they can also lead to a state of dehydration when the water and mineral losses linked to perspiration are not compensated by sufficient intake. Among the most common symptoms of moderate dehydration , we find headaches , dry mouth , body aches , fatigue or irritability. Although these symptoms are most often mild, a state of dehydration should not be taken lightly. Indeed, in the absence of rehydration , serious symptoms - such as impaired consciousness and disorientation - may appear and the proper functioning of vital organs may be compromised. It is also for this reason that during a heat wave , particular vigilance is required among vulnerable people such as seniors, infants or people with chronic illnesses.
Simple rules for good hydration during the summer
In order to preserve your health, it is therefore essential to ensure that you are well hydrated during the summer. How ? First, by drinking enough water. The recommended daily intake during periods of high heat and heat waves is 1.5 to 2.5 litres, but these recommendations can naturally vary according to profiles, level of physical activity and duration of exposure to heat.
Contrary to popular belief - you should not wait to be thirsty to drink! Indeed, the feeling of thirst is like an alarm signal sent by the body: it already testifies to a slight dehydration .
Another important aspect: food. It must be varied and rich in fruits and vegetables, the latter having the advantage of containing a lot of water and many minerals ensuring essential functions within the body. Magnesium , for example, helps reduce physical and cerebral fatigue , sodium determines the amount of water present in cells, zinc , for its part, contributes to the proper functioning of the immune system , chloride helps digestion, potassium participates in normal muscle function and manganese, finally, protects cells from oxidative stress ( antioxidant ). Compensating for part of the mineral losses caused by perspiration during high summer heat is therefore essential.
