The Brain and Water? Why Water Is Needed for a Healthy Brain?


Did you know that 85% of your brain is water? This fact alone tells us a good deal about why water is essential for the brain, and it may seem strange that the brain needs water, given that your body needs it to keep from dehydrating. But your brain is also getting a good share of the water you drink. A dry brain is equal to dry wit. Not enough water in the brain can lead to irritability, concentration difficulties, headaches, cognitive problems, or what is commonly referred to as “brain fog.”

If you have ever suddenly felt tired or had trouble concentrating for no apparent reason, you may have already experienced brain fog and not know it. This blog post will shed light on why water is essential for brain health

The brain, and why drinking water is important

The Brain and Water: Why Water Is Needed for a Healthy Brain

Although the brain is a lot like crunchy ol’ bone in some ways, this organ is full of fluid—approximately 80% of its total weight is water. However, unlike other organs, your brain does not have a circulatory system to deliver fresh blood and oxygen. This means that your brain must depend on the blood that circulates in your body to supply it with oxygen, glucose, and essential nutrients. Unfortunately, this means that the brain is vulnerable to the same fluid loss that affects other organs.

Hypothalamus, the water-loving region of the brain

What does this mean? It means that dehydration of your whole body can affect your brain. The hypothalamus, for example, is a specialised region of the brain that has been shown in studies to be particularly vulnerable to dehydration. The hypothalamus is responsible for the regulation of body temperature, hunger, sleep cycles, and alertness. It is also responsible for keeping your body in balance by regulating the release of hormones. When you become dehydrated, your hypothalamus becomes overactive, causing increased urination and thirst in an effort to re-establish stability.


Water Fuels Brain Activity

The brain is not the only organ that is overactive when you become dehydrated. The kidneys, adrenal glands, and pituitary glands all increase their activity. The adrenal glands, which sit atop your kidneys, are involved in the stress response and the regulation of blood pressure. When dehydrated, the adrenal glands release a hormone called cortisol. This stress hormone is essential for survival in the short term, but it can be harmful to long-term health. Overproduction of cortisol can lead to chronic fatigue, weight gain, and muscle aches. In the worst cases, high levels of cortisol can lead to depression, memory loss, and vision problems. These are reasons enough to take water seriously.

Why Water Is Important for Your Brain

Water transports nutrients such as glucose, amino acids, and fatty acids to the brain and carries away waste products such as carbon dioxide and lactic acid. Its function can be compared to that of the arteries, veins, and lymphatic system in the rest of your body. While the rest of your body is focused on supplying nutrients and taking away waste, your brain is focused on supplying nutrients and removing waste, but with a major difference. The brain has a much higher metabolic rate than any other organ in your body.

The brain is responsible for a variety of daily functions—from regulating your body temperature to making you feel hungry or keeping you from feeling exhausted when you need to be alert. Because it is so incredibly active, the brain has a high metabolic rate, which means that it needs a lot of energy. In fact, the brain burns about 25% of the oxygen that you take in. Not only does water supply your brain with the energy it needs to help it function, but it is also necessary for removing toxic waste products. So, don’t skimp on the water!
