Does drinking water reduce brain fog? (2023)

How much water should I drink for brain fog?

For people under 60 years of age, “35 millilitres of water per kilogram of body weight per day is the calculation dietitians use clinically,” according to Medlin. For most healthy people this is between two to three litres per day, she added.

If you're dehydrated, you may start to feel dizzy. This feeling can cause you to also experience lightheadedness, wooziness, fairness and unsteadiness.

Brain fog can come with stress, poor sleep, and overexertion, but if yours is persistent, gets in the way of your day-to-day life, or negatively affects your mental health, you should talk with a healthcare provider. There may be an underlying cause.

Getting enough water every day is important for your health. Drinking water can prevent dehydration, a condition that can cause unclear thinking, result in mood change, cause your body to overheat, and lead to constipation and kidney stones.

You can help yourself recover, because brain fog improves with healthier lifestyle choices. The "basics" are eating healthier, getting enough sleep and rest, and increasing physical activity (gradually). Reducing stress is also important.

Prolonged dehydration causes brain cells to shrink in size and mass, a condition common in many elderly who have been dehydrated for years. Lack of mental clarity, sometimes referred to as “brain fog.”

Reducing stress, improving sleep quality, and supporting cognitive health may all help relieve brain fog. L-theanine may reduce brain fog symptoms such as memory problems and delayed reaction time when taken as a supplement.

Vitamin D can improve brain health, reducing symptoms of brain fog. The brain treats vitamin D as an antioxidant, leading to improved cognitive function, more melatonin production, and hormone control.

What can I drink for mental clarity?

Hydrating: in addition to a healthy diet, hydration may help reduce brain fog. Many important electrolytes such as potassium, magnesium and sodium are required to maintain proper cellular function. These minerals ensure that fluid is kept inside the cells where it is needed.

Drinking water can improve one's brain health by simply increasing blood flow and oxygen to the brain – which, in turn, improves concentration and cognition (supporting memory function) and helps balance moods and emotions, reducing stress and headaches.

When you're dehydrated, your brain and other tissues in your body shrink (contract). As your brain shrinks, it pulls away from the skull, puts pressure on nerves and causes pain. Even mild dehydration can lead to a headache.

When you drink too much water, you dilute the sodium levels in your blood. When it's a mild dilution this can cause cramping, fatigue, and brain fog. When levels fall below 135mmol/L it's known as hyponatremia. Hyponatremia is bad news.

Your brain is strongly influenced by your hydration status. Studies show that even mild dehydration, such as the loss of 1–3% of body weight, can impair many aspects of brain function. In a study in young women, researchers found that fluid loss of 1.4% after exercise impaired both mood and concentration.

Research also shows that water is important for maintaining your mental health. Dehydration may increase your risk of anxiety and depression, among other unhealthy mental states.

Water helps your brain cells communicate with each other, clears out toxins and waste that impairs brain function, and carries nutrients to your brain. This all falls apart if your fluid levels drop.
