Why do humans need to drink water
Apart from air, water is the most important resource that a human being needs for survival.
Fresh water is necessary for all living organisms on Earth. Our bodies are made up of about 60% water and we cannot survive more than a few days without it. Water is a precious substance that meets our physical needs while at the same time being of great spiritual importance to many people. Water is also an integral part of many ecosystems that support us and a myriad of other species. But The specific question is, why do humans need to drink water ?
Drinking water does more than just quench your thirst. It’s essential to keep your body functioning properly and feeling healthy. Nearly all of your body’s major systems depend on water to function and survive. You’d be surprised about what staying hydrated can do for your body.
Benefits and Essentials
Here are just a few important ways water works in your body:
- Regulates body temperature
- Moistens tissues in the eyes, nose and mouth
- Protects body organs and tissues
- Carries nutrients and oxygen to cells
- Lubricates joints
- Lessens burden the on kidneys and liver by flushing out waste products
- Helps dissolve minerals and nutrients to make them accessible to your body
Every day, you lose water through your breath, perspiration, urine and bowel movements, which is why it’s important to continue to take in water throughout the day. For your body to function at its best, you must replenish its water supply with beverages and food that contain water.
How much water should you drink each day?
Water is essential to good health. Are you getting enough?
It’s a simple question with no easy answer.
Studies have produced varying recommendations over the years. But your individual water needs depend on many factors, including your health, how active you are and where you live. No single formula fits everyone. But knowing more about your body’s need for fluids will help you estimate how much water to drink each day. So how much fluid does the average, healthy adult living in a temperate climate need?
An adequate daily fluid intake is:About 15.5 cups (3.7 liters) of fluids a day for men, About 11.5 cups (2.7 liters) of fluids a day for women. These recommendations cover fluids from water, other beverages and food. About 20% of daily fluid intake usually comes from food and the rest from drinks. What about the advice to drink 8 glasses a day? You’ve probably heard about that rule.
Each person is different
That’s easy to remember (8Glass/day), and it’s a reasonable goal. Most healthy people can stay hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than eight glasses a day might be enough. But other people might need more. You might need to modify your total fluid intake based on several factors. Exercise: If you do any activity that makes you sweat, you need to drink extra water to cover the fluid loss. It’s important to drink water before, during and after a workout. Environment. Hot or humid weather can make you sweat and requires additional fluid. Dehydration also can occur at high altitudes. Overall health. Your body loses fluids when you have a fever, vomiting or diarrhea. Drink more water or follow a doctor’s recommendation to drink oral re hydration solutions. Other conditions that might require increased fluid intake, include, bladder infections, urinary tract stones, pregnancy and breast-feeding. If you are pregnant or breast-feeding, you may need additional fluids to stay hydrated.
The question that comes again, why do humans need to drink water? Lack of water can lead to dehydration. A condition that occurs when you don’t have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired.
Water is your body’s principal chemical component and makes up about 50% to 70% of your body weight.
Drinking too much water is rarely a problem for healthy, well-nourished adults. Athletes occasionally may drink too much water in an attempt to prevent dehydration during long or intense exercise. When you drink too much water, your kidneys can’t get rid of the excess water. The sodium content of your blood becomes diluted.
This is called hyponatremia and it can be life-threatening.
Other sources of fluids
Is water the only option for staying hydrated? No! You don’t need to rely only on water to meet your fluid needs. What you eat also provides a significant portion. For example, many fruits and vegetables, such as watermelon and spinach, are almost 100% water by weight. In addition, beverages such as milk, juice and herbal teas are composed mostly of water.
Even caffeinated drinks, such as coffee and soda can contribute to your daily water intake. But go easy on sugar-sweetened drinks. Regular soda, energy or sports drinks, and other sweet drinks usually contain a lot of added sugar, which may provide more calories than needed. How do I know if I’m drinking enough? Your fluid intake is probably adequate if, you rarely feel thirsty, your urine is colorless or light yellow.
Your doctor or dietitian can help you determine the amount of water that’s right for you every day.

You may have heard that you can get water from a cactus if you are ever lost and dehydrated in a desert. Sounds like a nice survival tip to store away, but is it really that easy? Turns out, a cactus is not actually a spine-covered basin of fresh water. Such a plant would not last long in an arid habitat filled with thirsty animals. Why do humans need to drink water? Water is truly a precious resource in a desert, so, in addition to their intimidating spines, most cactus species further protect their spongy flesh with acids and potent alkaloids. These chemicals are usually too acrid for most humans to tolerate and are taxing on the kidneys if ingested. The flesh of some cactus species can also cause vomiting, diarrhea, or temporary paralysis none of which is conducive to your survival in an emergency situation. The notable exceptions to this rule are the prickly pear and one species of barrel cactus, the fishhook barrel. While both of these plants are fairly unpleasant to eat raw, they have less-concentrated levels of the detrimental chemicals and could give you a bit of hydration in a pinch. Cactus fruits are a better bet, though many are also unpalatable if eaten raw
The human body can survive for about three days without water, which can be extremely hard to find in hot desert climates.
