Karateka and author Chris Denwood, Sensei has penned a nice article on The Importance of Water for people in training – a topic I’ve written about before. Although there isn’t a universal recognition of this issue, some scientists believe that chronic dehydration is linked to a range of diseases.
75% of people around the world are chronically dehydrated.
This is amazing on the surface, when you consider that people are drinking so much – coffee, softdrinks, alcohol, energy drinks, etc. But how much is enough? Well some experts state that you should drink a litre of water per day per 25kg of body weight. I don’t know many people that would actually do that!
alcohol and many soft drinks actually steal water from the body and other beverages such as coffee require water from the body to be digested.
It seems like good, old fashion, natural water is the best thing. The 25 litres/kilogram guideline applies to water only. Other drinks are at best neutral, but most require you to add more water in order to be correctly hydrated. One rule of thumb is that every cup of coffee, softdrink, alcohol means you should add the equivalent quantity of water back into your system.
Of course, this is a base level – when we train hard we need to replenish the water lost through perspiration.
A recent piece in The Conversation pointed out that softdrinks in particular are a growing problem in modern society, and that the levels at which they are being consumed present a growing public health issue.
I’ve come to the opinion that it’s not just the sugars in softdrinks (which are bad in and of themselves), but the chemicals in diet softdrinks are also a factor in the obesity epidemic, and serve to reduce people’s satiety levels.
This is a double-whammy. As Chris said in his post:
In over a third of all people, the thirst mechanism is so weak that it is often mistaken for hunger.
So people have reduced satiety levels from drinking too much diet softdrink, and they are also dehydrated, leading to more hunger! Not a healthy mix.
In the old days, karateka were often not allowed to drink water during class. We were told that sweating was good for us. In the Kengokan Dojo, I allow regular “water breaks”hydration pauses”, and insist people have some, especially during hard sessions or when the weather is particularly hot! I believe every instructor should take the same approach.
So for all reading this:
- Make sure your base level of water consumption is appropriate
- Eliminate, or at least drastically reduce, the amount of softdrink you’re consuming
- Take regular hydration pauses during your training
Oh, and one more thing – if you’ve not subsribed to Chris Denwood’s blog, do yourself a favour and do so now. Or follow @chrisdenwood on Twitter.
