Some doctors think that you should drink a glass of water each morning because its importance to your body. You should drink this water first thing, before doing anything else. The temperature of the water should be similar to body temperature; neither too hot nor too cold.
Water helps clean out your kidneys. It prepares your stomach for digestion. Water can also help your intestines work better. After drinking water, the intestines can more easily take out nutrients from our food. Water also helps us go to the bathroom more easily. Scientists suggest that people take in 1,600 milliliters of water each day. However, don’t drink all of that water in one sitting. If you do, your kidneys will have to work much harder to eliminate it. It’s better to drink some in the morning and some in the afternoon. Some people think it’s better to drink between meals and not during meals. They think water dilutes the juices produced in our stomachs. This can interfere with normal digestion.
