Water is often overlooked because it doesn’t have any colour, calories, or taste. However, it plays a vital role in all the functions of the human body. On an average, 60 per cent of the human body comprises water. Without it, human beings would simply not exist.

All the cells, tissues, and organs of the human body are composed of water. It transports nutrients in the blood, eliminates waste matter from the body through urine and sweating, and also lubricates joints, as well as protects sensitive organs like the brain and spinal cord. When the human body gets enough water, it functions properly. When it doesn’t get enough water, things start going wrong.

Even mild dehydration can cause changes in how a person feels. A loss of 1 to 2 per cent of the body’s fluid content can cause decreased concentration levels and alertness. A person may feel a headache, get tired, or feel dizzy. A person may think that they are hungry or feel fatigued, but in fact, they are simply suffering from dehydration, i.e., they simply need a glass of water.

Water also plays a significant role in regulating the temperature of the human body. When a person exercises or stays in a room that is at a higher temperature, their body starts sweating. When the sweat evaporates from the body, it cools down the body. When the human body doesn’t get enough water, it cannot regulate its temperature properly, leading to heat exhaustion, especially during hot seasons.

Water plays a significant role in the digestion of food that enters the human body. Water breaks down the food into smaller components so that the human body can take in essential nutrients like vitamins and minerals. A habit of drinking a glass of water in the morning can ensure that the digestive system of the human body remains regular.

In terms of kidney health, this organ depends a lot on water. Your kidneys filter 150 litres of blood every day. They remove wastes and also help keep fluids at a healthy level. If you don’t get enough water into your body, wastes can accumulate and lead to kidney stones or infections. Also, urine that is clear or pale yellow indicates that you are hydrated and healthy.

Water can also help you with your weight. Sometimes your body can get confused and mistake thirst for hunger. Drinking water before meals can help you avoid snacks. Also, by switching from other drinks like soda and juice to water, you can reduce calorie intake.

But how much water do you really need? Health experts generally recommend that people should have at least six to eight glasses a day. This amounts to about 1.5 to 2 litres. This can vary depending on your age, level of activity, and where you live.

You need to remember that not all fluids are equal. For example, tea and coffee can also help you keep fluids at a healthy level. Also, milk can help. However, soda and alcohol can have negative side effects.

In terms of your day-to-day life, you don’t need to plan much. All you need to remember is that you need to have a bottle with you at all times. Also, you need to remember that you need to keep drinking water at regular intervals.

Water may be a very ordinary commodity. However, its impact on your life can be very extraordinary.
