The brain and life-sustaining power of water.

When we talk about diet, we often just focus on food and leave out something else that we need to consume constantly if we want to maximize not just brain health but total health. And that’s water.

Did you know that we humans are really just water babies? Our bodies are 60% water, our brains are 75% water, and our blood is 90% water. And speaking of brains and water, ever notice why it seems like it’s harder to think clearly when you’re dehydrated?

That’s because it only takes 2% dehydration to start impacting brain function, and that as little as 1% dehydration can lead to a 5% decline in cognitive function.

In case you’re looking for yet more reasons to keep yourself constantly hydrated, check these out:

  • Water helps to keep your joints lubricated.
  • It helps to deliver essential oxygen throughout your body and especially to your brain.
  • It acts as a protective layer and cushion for the brain, the spinal cord, and other tissue and organs.
  • It’s the basis of saliva and mucus, and while they might not sound pleasant, they provide essential bodily functions.
  • It helps to promote beauty and skin health.
  • It’s essential for a healthy digestive system.
  • It helps to regulate your body temperature.
  • It helps to deliver essential nutrients throughout your body.
  • It helps to keep your kidneys healthy.
  • It’s essential for exercise and mobility.
  • It can help with weight loss.

So exactly how much water do you need to drink every day? The answer is simply, it depends:

  • On your activity levels.
  • On your age, size, weight, and physical build.
  • On any health issues.
  • On any medications you use.
  • On outside temperatures.

But it’s generally recommended that men should aim for around 15 cups of water each day and women about 11. Just make sure that you’re adjusting for anything that’s unique about you or your lifestyle.
