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, diarrhea, 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, colorless urine.
* A somewhat dehydrated body produces yellow urine.
* A severely dehydrated body produces orange or dark-colored 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?
For every 1 kg of your body weight, you need to drink 30 gm of water. Thus if you weight 50 kg, you'll need to drink around 1.5 kg or 1.5 litres of water a day. 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 flavors in soft drinks are harmful to your health. Tea, coffee, soft drinks contain water, but the diuretics contained in these caffineated 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 domestic water 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.
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. Most bottled water is simply tap water put through conditioning filters to make it taste better.
Pepsi and Coco-Cola both use 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 government 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, 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.
What about filter and filtered water?
It is always wise to get a filter if you are not sure how safe your tap water is. There are many water filter products on the market at many different prices. To shop for a good filter, you need to know what a filter factually reduces, or removes, and what it costs. Ideally, you want water that has been filtered via a reverse osmosis process that removes chemicals, pesticides, heavy metals, chlorine, fluoride, bacteria, and viruses.
How do you choose a good filter? It is important you do your own research – ask your local health food store, do on-line research and check the Consumers’ Report for products and prices evaluations.
Drinking tips for healthy hydration:
Start your morning’s right: Morning is when you are most full of toxin and dehydrated. Reach for a big glass of water first thing in the morning – even before coffee. This water in the morning really gets the blood flowing.
- Drink a glass of water when you get up and another when you go to bed.
- Take regular water break breaks.
- Avoid relying on sodas to provide your fluid need.
- Drink water before and after food; ideally drink a glass of water half an hour before you eat your meal and half an hour after the meal. You can drink water with meals, and drink water anytime your body feels like it.
It is very important you balance your sodium intake with your water consumption. Take 1/4 teaspoon of salt per every 4-5 glasses of water. Be sure to get sea salt. The best is Celtic sea salt or Himalayan sea salt, both of which are readily available at any health food store.
You should always drink water prior to eating, and after eating, to support the digestive process. The stomach depends on water to help digest food, and lack of water makes it harder for nutrients to be broken down and used as energy. The liver, which dictates where all nutrients go, also needs water to help convert stored fat into usable energy.
If you are dehydrated, the kidneys turn to the liver for backup, diminishing the liver’s ability to metabolize stored fat. The resulting reduced blood volume will interfere with your body’s ability to remove toxins and supply your cells with adequate nutrients.
Keep a water bottle by your side at all the times. Use either bottled water or tap water, and carry it with you everywhere, to the gym, in your car, to your office. Start by adding water to your daily regiment, during the first week, and then incorporate more as needed. The point is not to wait until you’re thirsty to drink.
Keep water flowing before, during and after workout. Don’t forget to balance your water intake with sodium intake. Drink at least 1 litre of water for every 60 minutes of exercise. Drink more if it’s hot. During exercise, such as playing sport on a hot summer day, you can lose up to 2 litres per hour of fluid per hour. Water and a balance salt is your best bet to keep healthy and hydrated. During exercise, it is recommended to replenish fluid at least every 20 minutes.
