Water – The Essence of Life
HOW DO YOU GET DEHYDRATED?
Through activities of daily living, the average person loses about 3- 4 litres (about 10-15 cups) of fluid a day in sweat, urine, exhaled air and bowel movement. What is lost must be replaced by the water/ fluid we drink and the food we eat.
“We lose approximately 1-2 litres of water just from breathing. The evaporation of sweat from the skin accounts for 90% of our cooling ability”.
Exercise, sweating, diarrhoea, temperature, or altitude can significantly increase the amount of water we lose each day. The most common cause of increased water loss is exercise and sweating. Even though we are all at risk of dehydration the people most vulnerable are infants, elderly adults, and athletes. They are either not able to adequately express their thirst sensation or able to detect it and do something in time.
HOW DO YOU KNOW IF YOU’RE DEHYDRATED?
If you are thirsty, it means your cells are already dehydrated. A dry mouth should be regarded as the last outward sign of dehydration. That’s because thirst does not develop until body fluids are depleted well bellow levels required for optimal functioning.
Monitor your urine to make sure you are not dehydrated:
- A hydrated body produces clear, colourless urine.
- A somewhat dehydrated body produces yellow urine.
- A severely dehydrated body produces orange or dark-coloured urine.
The effects of even mild dehydration include decreased coordination, fatigue, dry skin, decreased urine output, dry mucous membranes in the mouth and nose, blood pressure changes and impairment of judgment. Stress, headache, back pain, allergies, asthma, high blood pressure and many degenerative health problems are the result of UCD (Unintentional Chronic Dehydration).
HOW MUCH WATER DO YOU NEED TO DRINK? WHEN TO DRINK?
To better determine how much water you need each day, divide your body weight in half. The answer is the approximate number of water ounces you should drink daily. You should drink half of your body weight in ounces. If you weight 200 pounds, you should drink 100 ounces water (3.13 quarts, 2.98 litres or about 10-12 cups of water a day). If you weigh closer to 100 pounds you will need only about 50 ounces of water or about four 12-ounce glasses daily. Individuals who are physically active or live in hot climates may needs to drink more.
WHAT SHOULD WE DRINK? WHAT SHOULDN’T WE DRINK?
We are designed to drink pure, natural water.
- Avoiding sodas/soft drinks to provide your fluid needs. The high sugar content and artificial flavours in soft drinks are harmful to your health.
- Tea, coffee, soft drinks contain water, but the diuretics contained in these caffeinated beverages flush water out of your body. Don’t count on them to replenish fluid loss.
- It is OK to drink them occasionally, but if you drink them constantly and don’t drink enough pure natural water, then you are severely compromising your long-term health.
- Natural pure water is the best choice. If you are committed to a healthy lifestyle and long-term health, make water a habit and a priority in your life
CAN WE DRINK TOO MUCH WATER?
During intense exercise the kidneys cannot excrete excess water. The extra water moves into the cells, including brain cells. The result can be fatal. For that reason, athletes should estimate how much they should drink by weighing themselves before and after long training runs to see how much they lose, and thus how much water and salt they should replace.
The studies that found 13% of the runners tested drank too much water, resulting in abnormally low blood sodium levels. The low sodium levels made many of these people very sick, and close to the point of death. The importance lesson here is to balance your water intake with your sodium intake.
HOW DO YOU KNOW IF YOUR TAP WATER IS SAFE TO DRINK?
Almost all-municipal water in is of high quality and very drinkable. The best source of specific information about the water quality in your area is your local water supplier. Water suppliers are required to send their customer an annual water quality report. Contact your water supplier to get a copy, or see if your report is posted on line.
It is important you know your local sources of water quality, and the quality of your local drinking water. To get facts and information about your tap water, drinking water standards and contaminants, contact your local water supplier. The Environmental Protection Agency (EPA) and American Water Works Association (AWWA) are the two credible institutions that provide information you need regarding quality of your water.
WHAT ABOUT BOTTLED WATER?
Bottled water’s biggest advantage is convenience. The Americans now drink more water from bottles than any other nation. Bottled water in is a $16 billion-a-year industry.
EPA sets standards for tap water provided by public water systems. The Food and Drug Administration (FDA) sets bottled water standards based on EPA’s tap water standards. Most bottled water is simply tap water put through conditioning filters to make it taste better. Pepsi’s Aquafina and Coco-Cola Co’s Dasani are both made from purified tap water. This doesn’t make it bad, but is something to consider when adding up cost and benefits.
Bottled water is safe to drink if it meets the standards. Contrary to popular belief the FDA does not carefully regulate the bottled water industry; therefore even bottled water can be impure unless it is the right kind of water. There are indeed many right kinds of high-quality bottled water that come from great natural water sources, such as spring, glacier, and mineral water. High-quality bottled water may be a desirable option for people with special health needs and those who can afford the price.
Just make sure your choice of water does not become a limiting factor to drinking it. If you are drinking less water because of the cost of bottled water, supplement your bottles with reusable bottles or just fill up a previously used bottle with H20 from the tap.
WHAT ABOUT FILTER AND FILTERED WATER and What about problems with dehydration?
It is always wise to get a filter unfortunately at medical and professional sport level we can not be sure how safe tap water is.
There are many water filter products on the market at many different prices. But you need to know what a filter factually reduces, or removes; you want water that has been filtered via a reverse osmosis (RO) process that removes chemicals, pesticides, heavy metals, chlorine, fluoride, bacteria, and viruses. Then you want water that provides safe drinking Ph. RO water is acidic.
The government regulate that tap water has to be 7.0Ph minimum. Doctors Health specialists, Nutritionists, Strength and fitness coaches all experts in their field recommend a Ph of 9.5. So a filter system that can clean via RO and then add balanced minerals, provide a Ph of 9.5 and Antioxidants is without question the optimum hydration choice. As stated below by Top Sports Nutritionist Matt Lovell
“If you’re going to opt to filter your water at home, your sports club, professional or amateur. I recommend a Reverse Osmosis filter with alkalising benefits, if that is too expensive then opt for a straight RO system and eat lots of green veg and have green supplements as well.” – Matt Lovell
