Water is an indispensable nutrient of our bodies. Up to 70% of the human body is water. A certain amount of water must be consumed each day in order to survive.
The excellent ability of water to dissolve so many substances allows our cells to use nutrients, minerals, and chemicals in biological processes to give energy and keep us healthy. It forms saliva. The foods in our bodies are metabolized and transported by water in the bloodstream.
By sweating and respiration, water maintains the internal body temperature and it lubricates our joints. It helps to flush out the waste materials from our body. Also, it acts as a shock absorber for the brain, spinal cord, and fetus. Water is needed for overall good health.
Different people need different amounts of water to stay healthy. Fluid loss occurs continuously, from skin evaporation, breathing, urine, and stool, and these losses must be replaced daily with sufficient water amount in order to be healthy.
When intake does not equal output, it leads to dehydration. When cells don’t maintain fluid balance, it can cause fatigue. Dehydration can occur in anyone, but it is most dangerous in babies, small children, and older adults. They have an increased chance of dehydration because of a high metabolic rate, as the immune system is not fully developed. Older people do not feel thirsty as young people. Their kidneys do not perform well and cause frequent urination. Dehydration can cause dizziness and confusion, sunken eyes, and dry mouth.
It is really important to drink water. You can also quench your thirst with hydrating foods. Foods to consider include cucumber, radishes, tomatoes, green peppers, cauliflower, watermelon, spinach, broccoli, carrots, and cantaloupe.
Successful hydration requires a measure of planning. Drink before you feel thirsty. Avoid alcohol and sugary drinks. Track your water intake.
