why do people need water?

Answer 1

Why do we need water?
¨ To carry nutrients and waste in the body
¨ To lubricate joints, digestive tract and body tissues
¨ To cool the body, especially during periods of physical activity.
What happens when you don’t get enough water?
Our bodies can survive without some nutrients for months, but we can only live for
5-10 days without water! We lose water when we sweat, when we breathe and in
body waste. An adult loses up to 2-3 quarts of water per day normally. An athlete
can lose up to 6 cups of water in just one hour of continuous activity.
Inadequate fluid intake can lead to constipation and dehydration. Besides
decreasing your endurance, dehydration can cause serious effects like heat stroke
to occur. Even a small amount of dehydration (1% of body weight or 1.5 pounds on a
150-pound person) can increase your risk of impaired performance and heat injury.
How much water do I need?
Most people need about 6-8 glasses of water each day. Caffeine-containing
beverages (coffee, tea, colas, etc.) should not be included in this amount because
caffeine acts as a diuretic and actually causes you to lose water.
More water may be needed during times of fever, illness, or extreme
temperatures. Athletes should drink additional amounts before, during and after
exercise. A good rule of thumb is to add 1-3 cups of water per hour of physical
activity. Thirst is not the best indicator of hydration. Often an athlete can be
dehydrated and not feel thirsty.
If you ignore your thirst, you may start to show signs of mild dehydration:
¨ dry mouth
¨ less urine when you go to the bathroom
¨ dizziness or light-headedness

Answer 5

the majority of the chemical composition of an average human is made up of water, which is more than 70%, i believe.. and our blood has a high percentage of water in it, so if we dont drink water one of the many consequences is that our blood will be more thick due to the absence of water and the heart will have a hard time to pump to blood and it may cause a heat stroke, this happens on people on hot climate temperatures when they dont drink water and become dehydrated.
All the more, water helps to release waste materials in our body.
