Importance of water | 10 Benefits in our life and amazing facts

Water is an essential requirement for life. After air, it is the second vital requirement for survival.

Water comprises approximately 70 to 80% of total body mass. It is so widely distributed in the body such that there is no cell or tissue in the body where you don’t find water.

It is tough to survive even a few days without drinking water.

Similarly, it is also necessary for the growth of plants and animals which supply our food.

So, with this in mind let us see the specific benefits of water.

Importance of water in the human body

1. For Metabolism and Biochemical Reactions

importance of water in our body

All the biochemical reactions in our body require water. These biochemical reactions occur by either synthesis of a substance or degradation of it.

Even the enzymes which regulate the biochemical reaction also depend on pH  (water component) for proper function. Hence, It is the mediator of all the principal biochemical events in the body including cell survival, birth, and death.

2. Body Physiology

Water also helps in all major functions of the body like circulation, excretion, absorption, nerve conduction, respiration, reproduction, etc. The body physiology largely relies on nerve condition, hormonal secretion, enzyme actions, etc. All these need water in one or another way.

3. Circulation

Blood is a connective tissue in our body that helps in the supply of nutrition and oxygen to each and every cell. This blood comprises about 50% of water. Similarly, the water forms the lymph and also cerebrospinal fluid (fluid in the brain) along with other fluid substances.

4. Absorption

It facilitates the absorption of food from the intestine by the process of diffusion and sinks condition. The absorbed food is carried by blood, lymph, and supplied to all organs and tissues.

5. Excretion

It helps in the collection of waste materials from all the cells and tissues of the body. From there it is sent to the kidneys, skin, and lungs for excretion. By kidney, waste is expelled as urine in combination with water. Through the skin, it is excreted via sweat.

6. In reproduction

Water helps in the formation of media for the transport of sperms and ova. The baby in the womb is also surrounded by fluid made of water.

7. Regulation of body temperature

Water helps in the loss of excess heat from the body in the form of sweat and also by respiration. When the body temperature is high, we drink more water to minimize it.

8. Miscellaneous

It keeps the eyes, mouth and other organs moist to perform smoothly. One cannot see clearly without moisture in the eyes. Water in the eyes helps clean the lens regularly. Without moisture, it would be even hard to chew the food properly and then swallow it. Hence, we need saliva formed from water in the mouth for the purpose.

Importance of water for plants

Plants are the prime source of food, clothing, medicine to humans and animals. Water is of prominent importance to their nutrition, growth, and formation of food. The importance of water for plants is as follows.

8 Plants can make their food material by photosynthesis. This forms starch a form of carbohydrate using water (from the soil), Carbon-dioxide (from the air) in the presence of sunlight.

9 Water helps in the movement of nutrients and other substances like hormones through the body. Since plants do not have a circulatory system, the distribution of material occurs by water. This happens through processes like capillary action. Imbition etc..

10 Germination of seeds. Seeds can germinate only in the presence of water. In most cases, the seed gives birth to a plant or tree.

The seed is an inert or dormant form of a plant cell with sufficient reserve of food material enclosed in a hard seed coat.

When dropped into the soil, the seed absorbs water by the imbibition process. The food material and other contents swell due to water and the coat ruptures revealing the growth and germination of the seedling.

The process of enzyme activity, energy production is initiated due to the presence of water. Growing slowly, the seedling germinates out of the seed into a big plant.

11. Water also helps in the loss of heat from plants by the process of transpiration through stomata.

Importance of water on earth:

12. Sanitizer

Water is the key substance that cleans the earth’s surface. It carries away any waste material or loose material from the earth’s surface into the oceans. Thus water keeps the earth’s surface clean and fit for living.

Water is the safe method of disposal of industrial waste. Once waste from the industry is treated well, it is released into rivers to be carried away into the sea.

13 Water cycle

Waters’ ability to evaporate by heat and condense by cool helps in the water cycle. Because of this, there is sufficient fresh water to drink and for irrigation on the earth’s surface.

14 Aquatic environment

Water occupies up-to  70.8% of the total landmass. It thus provides life for many marine animals and also plants.

Other amazing facts about water:

♣ Water is absorbed to a large extent from the stomach itself and less from the intestine. Hence when water is consumed the thirst is quenched immediately as the body water level rises due to rapid absorption from the stomach.

♣ Water has a neutral pH of 7.o.  This makes it a universal solvent.

♣ Water helps in the breakup of tablets, capsules of drugs, and other health supplements we take and help in easy absorption into the body. importance of water

So even syrups and other liquid dosage forms are prescribed for old age patients because of faster and complete absorption of drugs in water made solution.

♣ Water carries carbon-dioxide in the dissolved form from tissues to excrete by lungs. And also to some extent supplies oxygen to remote areas of the cell.

♣ Water is also formed in the body directly by the process of combustion of carbohydrates with oxygen.

♣ Most of the body waste materials are water-soluble. Any water-insoluble materials are converted to a water-soluble form for natural excretion through the water.

♣ Water levels in the cell and body compartments are maintained by ions of salts. That’s the reason why the increase in salt intake increases water levels in the body. Thereby there is a rise in blood volume and the associated rise in blood pressure. Also, there are chances of edema due to water accumulation for a prolonged period in the body.

Thus the importance of water is very huge. But due to human activity, it is prone to pollution. This water pollution, in turn, affects human health.
