Sometimes people complain, “Why do we have to drink so much water?” well, if you are one of them, maybe you need to know a few facts about water. 70% of the human body is composed of water. That is why every system and the vital organs in our body depend on water. It is considered as a universal solvent and transport medium. All biological processes based on water. We can even go without food for weeks, but we can never survive even for a few days without water. That’s how essential water is.
Although it has no caloric and nutritional value, there are a number of health benefits that water can provide:
- Flushes out waste and toxins out of your system
- Aid in digestion and nutrient absorption
- Regulate body temperature and circulation
- Lubricate joints and maintain skin integrity
The body does not store water and every day we lose it through breathing, perspiration, urination and bowel movements. It is also impossible that one can have water toxication due to the different eliminating mechanisms of the body. What comes in in our system will eventually come out later. This is why we should constantly supply our body with water to keep it functioning properly.
If your water level is too low, you will be at risk of dehydration. And the primary symptom of dehydration is thirst. Thirst is what drives us to drink water. It’s a sign that our body is lacking water and it needs to be replaced immediately. Moreover, dehydration can drain our energy and make us tired. And if not treated immediately, it can lead to serious complications and even death.
How much water do we really need? We hear most of the time that we need 8 to 9 glasses of water or 1.5 to 2 liters a day. But that is just a general rule. It only applies to the average adult, but not on infants, young children, and overweight people. The water a person needs vary according to age and body proportion. Children have lower water needs while fat people need more than the average. It also depends upon the climate’s place you’re living in. If you are living in a warmer climate, you might need to increase your water intake because you would be sweating hard most of the time.
How do you know if you’re drinking enough water? If you are rarely thirsty throughout the day and you produce 1.5 to 2 liters of urine or your urine is almost colorless, then that means you are drinking enough water.
