Drink Water For Your Brain

Hydration, or rather lack of it, plays a big part in age related memory loss. Water can be found in drinks and foods too, but beware of the type of drinks.

Water Your Brain Regularly!

You don’t need to be a rocket scientist to know that water is important for the human body to function! It’s right up there behind oxygen!

Our brains are about 77 – 78% water¹ (by comparison our muscles are about 75% water). Any changes in the amount of water in our body will soon affect the brain.

Signs you may not have enough water include:

• Headaches
• Tiredness or fatigue
• Lightheadedness
• Poor concentration
• Nausea
• Anxiety (because lack of water to the brain causes the release of the stress hormone cortisol)

If you don’t drink enough water, your blood volume decreases. Blood transports nutrients to muscles and body organs including the brain. When the blood volume decreases there is less oxygen and other nutrients to nourish, replenish and help grow new cells.

It is easy to see how even small amounts of change in this area can create the symptoms of headaches and tiredness.

Dr Michael Colgan² is attributed as saying that:

If you dehydrate a muscle by only 3%, you will lose 10% contractile strength and 8% of your speed.

If lack of water does that to your muscles, imagine what it does to your brain! Find out more about water and its effects on brain and body:
