The high heat of summer: how to rehydrate the whole family with the heat wave?
High temperatures and heat waves 2022
A heatwave, or heat wave , is defined as a level of very high heat during the day and night for at least three consecutive days. The definition of a heat wave is therefore based on two parameters: heat and duration.
In Western Europe, a heat wave is considered to be a night temperature above 18-20°C and a daytime temperature above 30-35°C.
In France, the heat wave is most often present in summer, in July or August.
The effects of the heat wave on our body
The risks to your health can arise from the first days of heat.
The body temperature exceeds 40 degrees, the skin becomes dry, hot and if the person is seized with violent headaches as well as vomiting, there is no doubt: it is heat stroke. This occurs especially at the start of a heat wave, when the body has not yet had time to adapt.
During hot weather, our body expends a large amount of energy to maintain the temperature at 37°, particularly through perspiration.
This implies a greater water and electrolyte loss.

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.
Some of the most common symptoms of moderate dehydration include:
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.
The digestive system, meanwhile, can also be affected by heat and dehydration. Therefore, more or less severe diarrhea may occur. This disorder can also lead to vomiting or a feeling of nausea.
During hot weather, the body evacuates water through perspiration, which reduces urine volume. So keep in mind that the more you sweat, the less you urinate.
In order to avoid this, it is necessary to drink more efficiently so as not to decrease this volume.
In the event of a heat wave, certain drugs and treatments are likely to aggravate a syndrome of exhaustion / dehydration or heat stroke, according to the ANSM (National Agency for the Safety of Medicines). People with chronic illnesses, infants and the elderly are the first to be affected.
According to doctors, a state of severe dehydration can lead to serious consequences, which can go as far as death.
Preventing and treating the effects of heat during a heat wave
Do not wait to be thirsty to drink! A quantity of water of 2L per day is necessary to keep your body hydrated during an episode of high heat.
If you do not have the possibility of having this quantity of water, Hydratis allows you better hydration, replaces the lost minerals and allows your cells to fight against oxidative stress.
Drink Hydratis during situations where you have an increased need for hydration (sport, heat wave, dry weather, alcohol consumption, poisoning) which will allow you to optimize water absorption during these times.
We advise you to dissolve two Hydratis lozenges in a large glass of water twice a day.
Maximize your hydration during these periods of high heat to optimize your energy, your health and your well-being!
