Water-Intensive Organ – Brain: Dehydration and Its Impact on Cognition
Feeling angry, upset, foggy, or unable to focus during a meeting? You’re probably dehydrated!
The brain is highly dependent on proper hydration. Composed of about 75% water, the brain is one of the most water-intensive organs in the body. Hydration plays a critical role in cognitive function, and its impact on mental performance and overall well-being needs to be widely understood.
The Role of Water in the Brain
The highly active brain needs proper hydration to function optimally. Here’s how dehydration affects brain function:
Understanding the Thirst Mechanism
Thirst is not just a random feeling; it’s a complex process controlled by several factors, including cellular dehydration, blood osmolality, hormonal changes, and environmental conditions. Here are the two primary reasons we feel thirsty:
- Cellular Dehydration: When the body’s cells lose water and shrink, the brain sends out signals to trigger thirst.
- Blood Osmolality (Hyperosmolarity): When there’s too much concentration of dissolved substances in the blood (like salts), the brain detects this change and prompts you to drink water to restore balance.
Other Reasons We Feel Thirsty
- Hormonal Signals (Vasopressin/ADH) – The brain releases vasopressin to trigger thirst when blood volume or osmolality is low.
- Low Blood Volume (Hypovolemia) – Baroreceptors detect low blood volume and signal the brain to induce thirst.
- Dry Mouth (Xerostomia) – A dry mouth sends signals to the brain, making you feel thirsty.
- High Salt Intake – The brain detects increased salt levels and triggers thirst to balance water levels.
- Temperature and Sweat Loss – When the body sweats or gets hot, the brain activates thirst to replenish lost water.
- Dry Environments – Exposure to dry air causes evaporation, prompting the body to signal thirst.
In summary, thirst is the body’s way of signaling that your cells are losing water and need replenishment to maintain proper function and balance.
Staying hydrated is essential for overall health, but sometimes it’s not easy to tell if you’re dehydrated.
Here’s a simple checklist, if you experience any of the following, it’s a clear signal that your body needs more water.
- Thirst – Feeling thirsty is the body’s obvious loud signal for hydration.
- Dry Mouth or Throat – A dry or sticky mouth indicates dehydration.
- Urine Color – Dark yellow or amber urine suggests dehydration.
- Infrequent Urination – Going to the bathroom less than usual.
- Fatigue or Sluggishness – Unexplained tiredness or low energy.
- Headaches or Dizziness – Common signs of dehydration.
- Dry Skin – Skin that feels tight, dry, or flaky.
- Mental Fatigue or Brain Fog – Difficulty focusing or thinking clearly.
- Muscle Cramps – Cramps or spasms due to lack of water.
- Irritability or Mood Changes – Feeling anxious or easily irritated
How Much Water Do You Need for Healthy Brain Function?
There’s no one-size-fits-all answer, but around 2 liters of water per day is a good baseline for most people. However, it’s not just about how much water you drink but whether it’s absorbed by your cells. Even drinking excessive amounts of water, like 10 liters, could still leave you dehydrated if the water isn’t properly absorbed by your cells.
Today, the water we drink is often over-processed, purified, and stagnant, which causes it to lose its natural energy and vibrancy. Fresh, natural water is full of life and easily absorbed by the cells. But today’s bottled and purified water lacks this vibrancy, making it harder for the body to use it effectively.
So, where’s the problem?
It lies in the water we drink!
Today, we’re too obsessed with drinking the cleanest water. Yes, it’s definitely the basic need to drink clean water. However, in the process, water has been over-travelled, over-processed, over-purified, and often left stagnant. In its natural state, at the source, water is vibrant, free-flowing, exposed to sunlight, and rich in energy at the molecular level.
When consumed fresh, this natural water is easily absorbed by the cells, meaning you might not even need to drink excessive amounts.
But today’s bottled, stagnant, and over-purified water has lost all of its natural vibrancy. Without this vital energy, the water struggles to penetrate and hydrate the cells properly, leaving you feeling thirsty or dehydrated despite drinking plenty.
Wow! So, how do we make the water efficient to ensure cells absorb it all?
