Providing you have sufficient liquid in your system the chemical ATP (adenosine triphosphate) is turned into ADP (adenosine diphosphate) during exercise and helps your muscles contract. That process is impaired if you're dehydrated. A good way to find out if you're drinking enough is to look at the colour of your urine after exercise. If it's dark, you're probably dehydrated.

If you're really worried about hydration and dehydration then weigh yourself before and after exercise. You shouldn't lose more than 2 per cent of body weight in fluid during any exercise session or your performance will decrease.

One of the big mistakes people make when exercising is only drinking when they are thirsty. Another is to assume you need sports drinks - which are sometimes packed with calories.

Unless you're exercising at really high intensity for an hour or more a day you probably don't need sports drinks to replace electrolytes such as sodium and potassium.

If you're exercising for more than 90 minutes the rules change; in that case consider drinking one cup of electrolyte drink every 15-30 minutes.

Parents have a responsibility to ensure their budding athletes drink enough when exercising. Younger athletes do not control the build-up of heat as well as adults so need to drink more regularly.

Children may not understand the need to keep hydrated, although they tend to be better than adults at responding to thirst, says Rush. Whenever children are exercising adults should offer them water during breaks.

No-one is the same. But there are some general guidelines for drinking and strenuous exercise:

Before: Drink about two to three cups of water a couple of hours before exercising and then about one cup around 15 minutes before.

During: Drink one cup of water if necessary every 10-15 minutes.

After: Have a larger drink after exercise. It's essential for recovery, ensuring that you can exercise tomorrow and the next day rather than feeling too tired to do anything.

I was asked the other day if we had considered marketing a zazen Alkaline Water System with a glass bottom tank.

I went on to answer the question by explaining how the zazen Alkaline Water System worked emulating Mother Nature's water cycle, producing a clean and balanced water with a broad range of essential alkaline minerals ideal for the body’s hydration needs - and therefore in this balanced state would not leach chemicals to balance itself.

It was at this point he exclaimed!......"Oh, I get it he said… so zazen Water is not hungry!”

What a great description “hungry water”. So I thought to myself, "note to self....use this description going forward!"

So if zazen Water isn’t hungry  - what water is hungry?

Simple, any water that is acidic (lower than 7.0pH). Did you know that rainwater can be as low as 5.7 pH (acidic) and up to 7.0 pH (neutral). Why? Because it has not collected any alkaline minerals from earth yet and therefore not alkaline but acidic to neutral.

Many of the bottled waters in plastic bottles are hungry! Water created by the distallation and reverse osmosis methods create hungry water! They will leach minerals from the drinker in order to get absorbed or will leach chemicals from containers where possible.

PS. The zazen Alkaline Water System is BPA free. EVERY part of the system is BPA free - the filter cartridge housing; seals, tap and tanks – are all BPA* free.
It is important to remember that it is not just the tank that the water sits in but also ALL parts that water comes in contact with you should consider. 

What is BPA?
Bisphenol A is a chemical used in cheaper plastics which helps harden the plastic – it is a chemical which is described as an endocrine disruptor and the body takes in BPA, if it is present, thinking it is estrogen. BPA is called a “false estrogen”  and the body cannot discern any difference. Studies show endocrine disruptors have been associated with cancer.

I was asked this past week by a doctor what the medicinal benefits of drinking alkaline water were. I have written below what I wrote to her with her subsequent reply below as well.

I explained that we measure the alkalinity by the pH of the zazen Alkaline Water System and this will vary slightly depending on a number of factors, however the pH can range on average around 7.4 and up to 8.5. The alkaline minerals help create great tasting alkaline water through the re-mineralisation process of the zazen Water System. The blood in our body is slightly alkaline at 7.4 pH so that is also a goal.

So the first point is given the fact that zazen Water contains essential alkaline minerals (especially the electrolytes); plus the system reduces the toxins in the originating water, so the body does not have to do the filtering of these… then we believe zazen Water aids in cellular hydration.  If we accept for a moment that if an individual is hydrated then the body is able to perform the tasks of releasing metabolic waste and draw nutrients more efficiently into the cell, then we can conclude that drinking zazen Alkaline Water assists create a healthier more alkaline state.

The second point we make in drinking zazen Water is as the water reaches the stomach (the alkaline water helps stimulate the stomach to release hydrochloric acid – which is good), this then stimulates the body to release bicarbonate buffers into the bloodstream (to balance the acid in the stomach otherwise there would be holes burnt through the stomach lining). 

These bicarbonate or alkaline buffers naturally released by the body, also help aid in reducing the toxin or acid load in the blood etc. again assisting create a healthier more alkaline state. We of course make no medical claim.

Here is the reply from the doctor.

“Dear Janet. Thank you for answering my question. You have gone to a great deal of effort to try and help me with my query and that goes a long way in my thinking. Thank you again!"
