Importance of Water
How much water do you really need?
One approach in water intake is the 8 x 8 rule. Drink 8 eight ounce glasses of water per day. Many people use this basic rule as a guideline for how much water you should have each day.
If you drink enough fluid so that you rarely feel thirsty and produce 6.3 cups or more of colorless or slightly yellow urine a day, your fluid intake is probably adequate. Also note that often feeling hungry is a sign of thirst. So have a glass of water before turning to a high carbohydrate or high calorie food.
What influences your water needs?
You may also need to modify your fluid intake depending on how active you are, the climate you live in, your health status, and if you’re pregnant or breast-feeding.
If you engage in an activity that makes you perspire, you need extra water. 1.5 to 2.5 cups should suffice, but exercise lasting more than an hour requires more fluid intake.
For intense exercise, use a drink that contains sodium to replace what is lost in perspiration and reduce the chances of developing hyponatremia, which can be life-threatening. Also continue to replace fluids after exercising. (Hyponatremia is a metabolic condition in which there is not enough sodium (salt) in the body fluids outside the cells. Symptoms include: abnormal mental status, confusion and decreased consciousness)
Hot climates or humid weather can make you perspire more and requires additional intake of fluid. Heated indoor air also can cause your skin to lose moisture.
Signs of illness, such as fever, vomiting and diarrhea, cause your body to lose additional fluids. You should drink more water and you may need oral rehydration solutions. Also, you may need increased fluids if you develop certain conditions, including bladder infections or urinary tract stones.
Staying Safely Hydrated
It’s not a good idea to use thirst alone as a guide for when to drink. By the time you become thirsty it’s possible to be slightly dehydrated. As you get older your body is less able to sense dehydration and send your brain signals of thirst.
To ward off dehydration make water your beverage of choice and consider the following:
Excessive thirst and urination can be signs of a serious medical condition. If you’re concerned, check with your medical doctor.
Water is your body’s principal component!
Water makes up about 60 % of your body weight. Every system in your body depends on water. Water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.
Lack of water can lead to dehydration, making it hard for your body to carry out normal function and even mild dehydration can drain your energy and make you tired.
Water is a natural appetite suppressant. Do not underestimate the power of this statement. Lack of water can lead to over eating. Your brain does not differentiate between hunger and thirst. So, when you think you are feeling hungry your body may be signaling you that you are thirsty!
