The human brain consists of around 85% water, and optimal brain function relies on this level being maintained. The brain, like the rest of your body, requires nutrition in the form of oxygen, water, and energy in order to function at its best.
Unfortunately most individuals do not drink water often enough and when we do, we drink too little. Most humans also do not breathe efficiently, thereby allowing blood sugar levels to rise and fall like a rollercoaster.
Without water the human brain cannot work properly; this is because it is water that keeps the brain signals working. It makes sense when one realise that the brain uses electricity to send signals to the rest of the body, and water is an excellent conductor of electricity. Drinking insufficient water results in the delicate balance of water and other elements in the brain becoming unbalanced, resulting in the brain cells losing efficiency.
When we do not drink enough water on a regular basis and our brains become dehydrated, it becomes extremely difficult to concentrate or focus our attention on something for longer than a few seconds at a time. Dehydration also affects our short-term memory as well as our long-term memory recall.
One of the scariest facts regarding drinking water and the health of our brains though may be the fact that dehydration actually makes brain tissue shrink. It is frightening to think that just 90 minutes of sustained sweating can cause a human brain to shrink as much as one year of aging does. Brain shrinkage also results in temporary loss of cognitive function. In actual fact, according to several researches, Alzheimer’s is actually caused by long-term dehydration of the brain.
Starting your day off with a large glass of chilled water first thing in the morning, before anything else, is vital to ensuring that you are drinking enough water every day to keep your brain functioning at optimal levels.
