We have been drinking water since our birth but did we ever wonder what does it do exactly? Why does our body actually need it?
Water is a combination of hydrogen and oxygen. It is the basis for the fluids of the body and makes up more than two-thirds of the weight of the human body. It is hence quite obvious that without water, human body would cease to function as each and ever cell and organs need water for its proper functioning
Body possesses two main fluid compartments: (i) Intracellular fluid which is inside your cells (ii) and extracellular fluid that circulates outside the cells. Water is also primarily responsible in regulating the temperature balance in your body. Salt, an electrolyte, also plays a major role in maintaining the osmolarity balance in your body. When you are dehydrated, your body must conserve water and excrete the sodium to prevent the sodium concentration from increasing. Similary, when you have excess water, your body retains sodium and excretes water to prevent sodium dilution. Such balancing of sodium plays a critical role in regulating blood pressure and blood volume.
Your body constantly loses water when you breath, sweat and even during the digestion of food. It is hence highly important to rehydrate your body by drinking fluids and eating foods that contain water. The amount of water one needs vary based on a variety of factors such as the climatic conditions, physical activty, and even the health problems or any illness that you are suffering.
Staying properly hydrated is very important also for your muscle strength and performance. Dehydrate a muscle by just 3% and you will cause a loss of about 10% loss of contractile strength, resulting in nearly 8% loss in agility. The most easy way to understand how well are you hydrated is by noticing the urine color. A clear urine indicates proper hydration; thirst is not always a right indicator and relying on the same could result in 50 - 75% dehydration.
Water does more than just quench the thirst or regulate your body's temperature; it also keeps the tissues in your body moist. In addition, water also acts as a lubricant and cushion for your joints. It aids digestion and helps remove waste from your body
Water is also required to -
- Moistens tissues such as those in the mouth, eyes, and nose
- Protects body organs and tissues
- It also helps prevent and relieve constipation by moving food through the intestines.
- Helps dissolve minerals and other nutrients to make them accessible to the body
- Regulates body temperature through perspiration
- Lubricates joints
- Lessens the burden on the kidneys and liver by flushing out waste products
- Carries nutrients and oxygen to cells
It is recommended to drink 3 - 4 litres of water every day. Plain water is not the only thing that contributes to fluid balance, other drinks and foods also contributes towards your body's water requirement. Majority of fruits and vegetables contain significant amount of water.
