You must have seen your grandpa drinking water on an empty stomach immediately after getting up and this might make you feel awkward. But truly this habit is filled with a lot of good things to follow in the entire day. It is often said that water is the most important component of the body and covers more than 75% of the body formation. so at least take 5-6 litres of water daily to have a proper health. water intake is important because not only will it keep the body hydrated, it can also be helpful in keeping the streams of blood flow going on. during the summer time, it becomes even more important because the body can get dehydrated soon with loss of water into it.
