Impact of poor hydration on the brain

Water is the fundamental element of our body, which represents about 60% of our total body weight. Hydration is crucial for our physical and mental health, especially for the optimal functioning of our brain. In this article, we'll explore the effects of dehydration on the brain and discuss ways to stay hydrated to prevent these negative effects.


The brain is 76% water.


The brain is mostly water, with 76% water in brain tissue. Water is an essential element for brain functions, such as transporting nutrients and oxygen, regulating body temperature, regulating electrochemical signals, and forming new memories.

Additionally, water is an important solvent for metabolic waste products, which must be removed from the brain for optimal functioning.


The effects of dehydration on our brain


Dehydration can lead to many symptoms, such as fatigue, headaches, trouble concentrating, dry mouth and throat, thirst, loss of appetite and decreased production of urine.

These symptoms can be caused by decreased blood volume and increased blood salt concentration, which directly affect the brain.

Additionally, dehydration can also cause headaches in sufferers. Headaches can vary in intensity and duration, ranging from simple discomfort to intense pain that can make it difficult to perform daily tasks.

Also, dehydration can affect concentration. People who are not properly hydrated may have difficulty concentrating on tasks or processing complex information. This can affect their performance at work or in their studies. It can also affect nerve conduction velocity and muscle responsiveness, which can lead to tremors and reduced coordination.

Monitoring urine color can help assess hydration level. Clear or pale yellow urine indicates good hydration, while dark or orange urine can indicate dehydration. A diet rich in minerals, such as salt, can help maintain the body's electrolyte balance.

How can Hydratis help you stay hydrated?

Drinking water is the simplest remedy to prevent dehydration. It is recommended to drink about 2 liters of water per day, but the amount may vary depending on weight, age and physical activity. Sugary drinks, such as sodas, fruit juices and energy drinks, can cause water loss in the body and should be avoided whenever possible.

Hydratis is a French company specializing in body hydration. The Hydratis solution enriches the water with mineral salts, sodium, glucose and trace elements. The lozenges are colourant-free, preservative-free and contain natural flavors (peach, berries, lemongrass, ginger, mint, anise, neutral).
This solution is very beneficial for the optimal hydration of the body, including for the brain. Indeed, water enriched with these components is quickly absorbed by the body, allowing effective and lasting hydration.

The mineral salt contained in the Hydratis solution is important for the water balance of the body. It helps regulate the amount of water in the cells and maintain good osmotic pressure. Sodium, on the other hand, helps regulate the amount of water in the body and plays an important role in the transmission of nerve impulses. Glucose, on the other hand, is a simple sugar that provides energy to the body, including the brain, which is one of the most energy-consuming organs in the body. Finally, the trace minerals in Hydratis solution are important for many bodily functions, including regulating body temperature, transporting oxygen, and producing energy.


Thus, by enriching the water with these components, the Hydratis solution allows optimal hydration of the body, including the brain. This optimal hydration helps prevent symptoms of dehydration such as fatigue, headaches and concentration disorders, which can affect intellectual and physical performance. By maintaining optimal hydration, the brain can function optimally, improving concentration, memory, and overall cognitive performance.


Overall, hydration is essential for the optimal functioning of our brains and our bodies. Dehydration can cause a variety of symptoms, such as fatigue, headaches, and trouble concentrating.

In conclusion, hydration is essential to maintain optimal functioning of our brain. The brain is 76% water and dehydration can have significant negative consequences on our mental and physical health. Symptoms such as fatigue, headaches, trouble concentrating and dizziness can all be linked to poor hydration.

Hydratis is very effective for optimal hydration of the body, including the brain. Enriching the water with mineral salt, sodium, glucose and trace elements helps prevent symptoms of dehydration and improves cognitive performance in general. For those looking to improve their hydration, it is recommended to regularly drink water enriched with these components, to monitor the color of their urine and to consult their doctor in case of doubt or persistent symptoms of dehydration.

It is crucial to consult a doctor in case of illness or symptoms of severe dehydration. Future research should continue to explore the effects of hydration on mental and physical health and identify new ways to help people maintain optimal hydration throughout their lives.
