Impact of poor hydration on the brain

Water is the fundamental element of our body, making up 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 will explore the effects of dehydration on the brain and discuss ways to better hydrate to prevent these negative effects.


The brain is 76% water.


The brain is composed primarily of water, with brain tissue comprising 76% water. Water is essential 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 wastes, which must be removed from the brain for optimal functioning.


The effects of dehydration on our brain


Dehydration can cause many symptoms, such as fatigue, headache, difficulty concentrating, dry mouth and throat, thirst, loss of appetite, and decreased urine production.

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

Additionally, dehydration can also cause headaches in those who suffer from them. Headaches can vary in intensity and duration, from simple discomfort to severe pain that can make it difficult to perform daily tasks.

Additionally, dehydration can affect concentration. People who are not properly hydrated may have difficulty focusing on tasks or processing complex information. This can affect their performance at work or in school. 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 levels. Clear or pale yellow urine indicates good hydration, while dark or orange urine may indicate dehydration. A diet rich in minerals, such as salt, can help maintain the body's electrolyte balance.

How can Hydratis help you hydrate better?

Drinking water is the simplest remedy to prevent dehydration. It is recommended to drink about 2 liters of water per day, but the amount can 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 as much as possible.

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

The mineral salt contained in Hydratis solution is important for the body's water balance. It helps regulate the amount of water in 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-intensive organs in the body. Finally, the trace elements contained in Hydratis solution are important for many bodily functions, including regulating body temperature, transporting oxygen, and producing energy.


Thus, by enriching 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 problems, which can affect intellectual and physical performance. By maintaining optimal hydration, the brain can function optimally, thus improving concentration, memory and cognitive performance in general.


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

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

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

It is crucial to seek medical attention if you are ill or have symptoms of severe dehydration . Moving forward, 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.
