Heat wave: drinking too much:
The heat wave that affects France should last several days. However, undermine the organizations, especially those of people at risk. In addition, Among the health effects of these high temperatures. Similarly, hyponatremia is a serious complication linked to an excessive water supply compared to salt. Nevertheless, Explanations. Moreover,
The heat wave will continue on Tuesday August 12 on a large part of France. Nevertheless, Sixteen departments of the Southwest are placed in red vigilance. Nevertheless, temperatures should remain very high until the end of the week. For example, During hot weather, we know well the risks represented by heat stroke or dehydration. For example, Less known, hyponatremia, however, represents a serious complication. The heat wave that affects France should last several days and undermine the organizations, especially those of people at risk. Among the health heat wave: drinking too much effects of these high temperatures. hyponatremia is a serious complication linked to an excessive water supply compared to salt. Explanations.
It’s what ? – Heat wave: drinking too much
Hyponatremia is a hydro-electrolytic disorder which corresponds to a sodium level (salt) in the blood plasma (natremia) lower than normal. i.e. less than 135 mmol/l. “Sodium plays a decisive role in maintaining the water balance between the interior and the exterior of the cells. This maintenance is essential for nerve transmissions and muscle contractions. It also plays an important role in the intestinal absorption of chlorine. amino acids, glucose and water and in their reabsorption at the renal level”, Specifies the National Food Health Safety Agency (ANSES).
In summer. when it is very hot, hyponatremia can be the consequence of an excessive water supply compared to salt or excess loss of salt in relation to water elimination.
What are the heat wave: drinking too much symptoms?
Symptoms of hyponatremia are:
- muscle cramps. weaknesses;
- nausea and vomiting;
- Lethargy or lack of significant energy;
- headaches;
- confusion;
- convulsions;
- the coma.
Who are people at risk?
The elderly are particularly at risk. They will not be able to compensate for an excessive contribution in water. Especially since in them, perspiration is sometimes altered even absent.
People who suffer from chronic diseases are also at risk (undernutrition, kidney failure, heart failure, liver insufficiency, diabetes, etc.).
Some drugs can also promote hyponatremia. They are first of all diuretics and certain psychotropic drugs.
Also be careful among athletes who practice a long -term effort while the climate is hot. The amount of sodium lost by sweat can lower its blood concentration below normal values. especially when the sportsman drinks too much water for sodium during effort.
How to prevent hyponatremia?
In 2023. the Ministry of Health issued the heat wave: drinking too much following recommendations to prevent hyponatremia in people at risk:
- Do not hydrate by excess with water alone (this is both useless and potentially dangerous) because other foods also bring water;
- Absolutely accompany drinks of a varied diet, by fractioning if necessary meals, to maintain a sufficient salt intake for the body (bread, soups, etc.).
- Bring an “artificial perspiration” if necessary (regularly wet the skin and ventilate it);
- Avoid outings outside during the hottest hours;
- Systematically, make the doctor reassess the diets (hyposoded) and current treatments (in particular diuretics) to judge the relevance of the maintenance or adjustment of doses at the time of the hot weather;
- Do not exceed a contribution of 1.5 liters of water per day in addition to foods already rich in water.
- Absolutely maintain a balanced and sufficient diet that will bring sodium.
The treatment of hyponatremia will depend on the cause heat wave: drinking too much and severity of the symptoms. Support may include a restriction of water supply and, for example, an adjustment of treatments.
