Water makes up 85 percent of the brain weight. So, it is but natural that lack of water can lead to brain shrinkage. Researches have shown that dehydration not only shrinks the brain tissues but also adversely affects concentration and memory. So, how much water is required by the body every day? Drink water according to your body weight. Dividing your weight in kilograms by 30 gives the amount of water in liters a day. For example, if you weigh 75 kg, drink (75/30= 2.5) 2.5 liters of water spread out over a day.
