You have probably heard that it is recommended to drink at least 1.5 liters of water per day. This is general advice, but it is important to qualify it because while water is essential in our daily lives, too much can be just as dangerous as too little hydration. Discover the risks of overhydration for your health and learn how to remedy it.
What is overhydration?
Overhydration is characterized by an excess of water in the body. This imbalance occurs when the kidneys can no longer eliminate excess water, often due to an excessive water intake. The excessive water intake then leads to excessive dilution of electrolytes in the blood, especially sodium, which plays an important role in regulating the distribution of water between cells and the extracellular environment. A decrease in sodium in the blood, called hyponatremia, disrupts this balance and affects the proper functioning of cells.
The consequences of this dilution can be serious: body cells, including those in the brain, can swell due to this water retention. This can lead to symptoms such as fatigue, severe headaches, altered consciousness, and in some extreme cases, seizures or coma.
What are the causes of overhydration?
The causes of overhydration are multiple and can be related to specific behaviors or medical conditions. Certain medical conditions, such as kidney or heart disease, aggravate this problem by reducing the kidneys' ability to filter water properly. In addition, some medications can cause water retention, thereby increasing the risk of overhydration. Finally, during intense physical exertion or in hot weather, excessive hydration may seem necessary, however, it is crucial to adjust your consumption according to the body's real needs to avoid harming the water balance.
What are the mechanisms?
When too much water is consumed, the body must regulate this intake to maintain optimal water balance. The kidneys, which are responsible for filtering blood and eliminating excess water through urine, can be overwhelmed by this overconsumption of water. If their capacity is exceeded, the excess water remains in the body and enters the cells, causing them to swell, a phenomenon that can cause edema in various tissues, including the brain, and lead to the most serious complications seen previously.
What is the difference with dehydration?
Overhydration and dehydration are two opposing states that disrupt the body's electrolyte balance. Dehydration occurs when the body loses more water than it receives, leading to a high concentration of sodium in the blood plasma. This can cause cardiovascular problems, dizziness or intense fatigue...
Conversely, overhydration leads to excessive dilution of electrolytes, especially sodium. This is called hyponatremia. Hypo... what? This word is made up of three Greek roots:
- hypo for "under," indicating a decrease or deficiency,
- natr for "natrium" meaning sodium,
- emia for "in the blood."
Hyponatremia therefore means a low level of sodium in the blood.
What are the risks associated with excessive water consumption?
An electrolyte imbalance
Sodium and other electrolytes play a crucial role in maintaining water balance and the transmission of nerve signals. Excessive water consumption lowers sodium levels in the blood, causing hyponatremia. This electrolyte imbalance can lead to water retention in body tissues, causing swelling or edema. Associated symptoms include fatigue, nausea, headaches, and in severe cases, seizures or coma.
Stress on the kidneys
The kidneys eliminate excess water from the body through urine. When too much water is consumed, they have to work harder to maintain fluid balance. If they cannot keep up, this can lead to water accumulation in the body, increasing the risk of water retention. In the long term, this additional stress can make the kidneys less efficient and increase the risk of kidney failure.
Other complications
Excess water in the body can also have serious consequences for the brain. Indeed, when brain cells absorb too much water, they can swell, causing cerebral edema. This swelling puts pressure on the skull, leading to serious symptoms such as severe headaches, altered consciousness, and in extreme cases, seizures or coma. These complications require immediate medical attention as they can be life-threatening.
How to identify and prevent overhydration?
Signs and symptoms of overhydration
The symptoms of overhydration may not be immediately visible and can manifest gradually. They include headaches, nausea, vomiting, confusion, general fatigue, or swelling of the limbs. In the most severe cases, symptoms such as seizures or a coma may occur, which are signs of severe overhydration.
Recommended water intake
The amount of water to consume each day varies from person to person, but generally it is advisable to drink around 1.6 to 2 liters of water per day. These needs are not fixed and must be adjusted according to each person's profile. For example, a person engaging in intense physical activity or exposed to a hot climate will need more water to compensate for fluid loss.
Tips for maintaining a healthy water balance
To prevent overhydration, it is crucial to listen to your body and adjust your water intake according to your daily needs. It is also recommended to promote a balanced diet that provides essential electrolytes such as sodium, to maintain good hydration. It is therefore important to include water-rich foods such as fruits and vegetables in your daily diet.
And Hydratis in all of this?
Hydratis tablets allow you to optimize your hydration thanks to their precise composition of minerals and trace elements. They will help maintain the body's water and electrolyte balance and promote water entry into the blood and thus into your body tissues. The tablets are formulated to help replenish electrolyte stores lost during physical exertion, during hot days or simply on a daily basis.
Our usage tips:
Simply dissolve one Hydratis tablet in a 250ml glass of water, twice a day. This ensures optimal hydration and helps you avoid the dangers of fluid imbalance, especially during intense physical exertion or heat. Thanks to their adapted formulation, the tablets optimize your water intake while maintaining the necessary balance to avoid the harmful effects of overhydration.
Overhydration is a little-known problem but one that requires particular attention to avoid drowning yourself :) Drinking enough water is essential for maintaining good health, however, it is just as necessary to do so in moderation! Listen to your body's needs by adjusting your water consumption according to your profile, your activity, climatic conditions, your state of health, you will thus be able to avoid the risks associated with excessive water consumption. You can carry out your hydration diagnosis online on our website to know your water needs according to your profile and your sports practice ;)
