• First link is a dubious "health" site not a link to scientific reference.

• Second link is about dehydration, need for hydration and effects/benefits of water on human body. The studies provided there relate to these facts. Drinking too little water is as bad as too much. also pointing out some obvious facts that when you endure athletic performance you p[erspire more so you need to replenish with water accordingly.
  There is mentioned about drinking half a litre of water before certain activities like eating etc. With relevant studies provided to support that.

Sadly, they also repeat the myth of drinking 2 litres of water a day but bring absolute no single study to support that claim. This whole article although brings up interesting information, in no way debunks my article that 2 litres of water idea is an arbitrary myth.

• Third link is about benefits of drinking water so it is irrelevant to the information I have provided in my article. Nowhere in my article it is said that drinking water has no benefits or that it is not important, etc.

My article is not about how much and what you eat because of drinking water but about myth of "2 litre of water a day" advise.
