Water is essential for the proper functioning of our body, and this includes the brain. The brain is made up of 73% water, and its proper hydration is crucial for maintaining brain volume and overall cognitive function. In this article, we will dive deep into the importance of water intake for maintaining brain volume and how it affects our brain’s overall health.
Understanding Brain Volume
First, let’s understand what brain volume is. Brain volume refers to the amount of space inside the skull that is filled by the brain. It plays a crucial role in regulating the body’s functions and maintaining overall health. A bigger brain volume is associated with better cognitive function, improved memory, and a lower risk of developing brain-related diseases such as dementia and Alzheimer’s.
Factors such as age, genetics, and nutrition can affect brain volume. However, one critical factor that is often overlooked is hydration. Studies have shown that proper hydration is essential for maintaining brain volume and its overall health.
How Water Intake Affects Brain Volume
Our brain relies on adequate hydration to function optimally. When we are dehydrated, the brain is unable to carry out its functions effectively. Here’s how inadequate water intake can affect our brain volume:
1. Shrinking of Brain Cells
When our body is dehydrated, the brain loses its water content, and this leads to the shrinking of brain cells. As a result, the brain volume decreases, and this can have a negative impact on the brain’s overall health and functioning. A study published in the American Journal of Clinical Nutrition has shown that even mild dehydration can shrink brain volume.
2. Reduced Oxygen and Nutrient Supply to the Brain
Water plays an essential role in delivering oxygen and nutrients to the brain. With proper hydration, the blood becomes thinner, making it easier for it to flow through the blood vessels and reach the brain. However, when we are dehydrated, the blood becomes thicker, and this hinders the flow of oxygen and nutrients to the brain. As a result, the brain is unable to function at its full potential, and this can affect its volume and overall health.
3. Increased Risk of Brain-related Diseases
Adequate hydration is crucial for maintaining brain volume and reducing the risk of developing brain-related diseases such as dementia and Alzheimer’s. Dehydration can cause cognitive impairment and memory problems, which are common symptoms of these diseases. Research has shown that a decrease in brain volume is linked to the progression of Alzheimer’s disease.
How Much Water Should You Drink?
The amount of water we need to consume daily varies from person to person. Factors such as age, gender, physical activity, and overall health can affect our water intake requirements. However, in general, it is recommended to drink at least eight glasses of water per day or half of our body weight in ounces. For example, if a person weighs 150 pounds, they should aim to drink 75 ounces of water daily.
It is also essential to keep in mind that our body loses water throughout the day, so it’s important to keep replenishing it by drinking water regularly.
Incorporating Water into Your Daily Routine
Drinking enough water might seem like a daunting task, but there are some simple ways to incorporate it into our daily routine:
1. Carry a Water Bottle
Having a water bottle with you at all times can serve as a reminder to drink water regularly. Keep it within reach, and take a sip every now and then to stay hydrated throughout the day.
2. Set Reminders
If you tend to forget to drink water, set reminders on your phone or calendar to remind you to take a break and have a glass of water.
3. Eat Water-rich Foods
Fruits and vegetables such as watermelon, cucumbers, and strawberries have a high water content and can contribute to your overall water intake.
4. Drink Water Before and After Exercise
Physical activity can cause us to sweat and lose water. Make it a habit to drink water before, during, and after exercise to stay hydrated.

In conclusion, water intake plays a crucial role in maintaining brain volume and overall cognitive function. By ensuring we are adequately hydrated, we can improve our brain’s health, function, and reduce the risk of developing brain-related diseases. Make sure to stay hydrated by incorporating the tips mentioned above into your daily routine.
