Why you should drink a lot of water?

Why you should drink a lot of water?

Scientists search on Mars only for water, why? Every planet is found in their telescope, the scientist thinks of water on their surface, why? Because water means life, a drop of water may be evidence of life.

The real truth is we are made of water!

Yes, about 60% of our body composition is water. Our brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

So, water means life. We always neglect to drink an adequate amount of water. Most people remain in the chronic dehydrated stage.

 Today Dr. Hasan's blog is discussing about, Why you should drink a lot of water?

Let’s see how our body needs water-

1. Water remains in every cell of our body:

More than 60% of a cell contains water. It persists as intracellular fluid as the main content of cell cytoplasm, enzymes, hormones, the main contributor of any cellular organelle in each cell. Or persist as extracellular fluid such as plasma, urine, peritoneal fluid, intestinal fluids, cerebrospinal fluid, etc. It is the main component of every organ of our body.

2. It is the primary mediator for every metabolic reaction:

Without water, any cellular organelle cannot work. Every metabolic response takes place by the presence of water. Dehydrated cells may die within a few hours.

3. Helps in growth:

Without water, cellular growth is impossible. Low water intake may cause restriction of cellular growth by reducing different hormone synthesis and arresting cell division like mitosis.

4. Helps to maintain the faction of every organ:

It is not only the main contributor to an organ formation; it is also necessary to maintain its normal physiology. Brain, heart, kidney, lungs, even hard bone also need water to maintain their normal function.

5. Transport function:

Blood is the primary transporter of nutrients and oxygen in our bodies. Plasma causes the transport of antibodies and electrolytes. Blood cells and plasma both are formed mainly by water. Blood cell production is dependent on an adequate amount of water in our bodies.

6. Immune function: Dehydrated people lose their immunity gradually. Immune cell production and transportation depend on body fluid.

7. Helps in digestion and absorption: It helps in the digestion of food by preparing different enzymes and gut hormones. It also helps to maintain our bowel habits.

Water has countless effects and needs in our bodies. These are the basics of our bodies. Without water, we can’t live. But these are not visible to us. So we don’t care about taking plenty of water.

There are some effects that we can easily understand-

1. It keeps you hydrated: Water keeps you hydrated, and you feel fresh.
2. Helps to maintain muscle strength: It helps to maintain muscle physiology. Dehydration may cause fatigue and weakness in your muscle.
3. Helps skin looking good: 64% of skin tissue is composed of water. Dehydration causes loss of your skin shininess, smoothness and increases dryness and wrinkle. We use different moisturizers to prevent dryness, but we are unaware of taking water or fluid adequately.
4. It helps cleaning the inner body: Kidney and stool with the help of water excrete different toxic waste products by the formation of urine and stool.
5. Helps in weight loss: It is a drink that contains no calories. It helps in fat burn, and adequate water intake may help to feel satiety. So, frequent water intake may cause weight loss.
6. Maintain regular bowel function: It is necessary to form a soft stool. Plenty of water drinking helps to get rid of constipating bowel habits.
7. Prevent joint pain: Synovial fluid acts as a lubricant in joint space. 98% composition of synovial fluid is water. So adequate water intake helps to prevent joint pain.
8. Prevents heart attack: Drinking the right amount of water reduces your risk of a heart attack. A six-year study published on 1st May 2002, the American Journal of Epidemiology found that those who drink more than five glasses of water a day were 41% less likely to die from a heart attack during the study period than those who drank less than two glasses. (http://aje.oxfordjournals.org/content/155/9/827.full)
9. Prevents headache: If you are mildly dehydrated, a headache may arise as your first symptom. Water is a need for the brain and CSF (cerebrospinal fluid). Most people may feel headaches at midday, because at that hour we may remain in a dehydrated state.
10. Mood improvement: Drink water makes you fresh. It has a significant effect on mood improvement.
11. Prevent cancer: Daily plenty of water taking reduces the risk of colon cancer by 45%. (http://www.ncbi.nlm.nih.gov/pubmed/10404059 )Bladder cancer by 50% (http://news.bbc.co.uk/2/hi/health/331514.stm) and potentially reduce the risk of breast cancer.

There are thousands of benefits to drinking an adequate amount of water. We all know most of them. Still, we don't drink an adequate amount of water.

How do water losses occur from our bodies?

Water is excreted in different ways, like-

1. Skin evaporation
2. Breathing
3. Urination (highest)
4. With stool
5. Salivation

Which factors increase water loss?

1. Hot and warm climate: causes excessive sweating.
2. Exercise: Increase sweating and breathing.
3. In high altitude: Increases breathing.
4. Older people: They have less subcutaneous fat. So skin evaporation increased.
5. Disease- Some disease-causing diarrhoea, vomiting, etc
6. Pregnancy and lactation.

So, if we are facing any factors among this, we have to intake more water than our standard requirements. Otherwise, kidneys and other organs will face problems.

 

The 8 cup myth:

It is a myth. It is not scientifically established that we need 8 cups of water daily. But it is true that if we take a minimum of 8 cups of water, we can easily maintain an excellent physical status regarding water demand. But if any of the dehydration causing factors is present, we have to take more water.

We all know about the importance and benefits of water. But still, we are drinking water as the second most popular drink! Yes, 1^st one is a soft drink. Water is maintaining the internal environment of our bodies. So, don’t be reluctant to drink an adequate amount of pure water.
