Drink or no drink?

[smutchin]

I just wanted to open a debate over we are not 100% follow the recommendations that we sell with economic interests.

Simplest answer to that is not to trust anything you see in adverts - ie "scientific" advice from people with a product to sell. I've become a lot more sceptical of taking advice since reading Ben Goldacre's Bad Science.

On the specific subject of hydration, I think that most of us, most of the time, just respond to our body's signals - we feel thirsty, we have a drink. And those of us who cycle a lot, and cover very long distances (eg audax), tend to learn from experience what our body really needs. Perhaps this isn't the optimum approach, scientifically speaking, but since very few of us here are performance athletes, it possibly doesn't matter so much.

I often see fellow cyclists on rides measuring out their powders and potions, as if they are carrying out some highly precise scientific process, but I wonder how many, if any, of them really understand the science behind their energy drinks or if they've just been suckered in by advertising and cycling folklore.

Taking an individualistic approach is good advice. I certainly don't think any of us should just copy what the pros do, because their physiology and work rate are entirely different to us mere mortals.

The exercise assicated hyponatremia (EAH) occurs when the body retains too much water. There is no other cause. Not every who drinks to excess develops EAH. Simply excrete the excess fluid. But in a small proportion, the fluid is retained and this is faulty. This occurs because the regulation of the total body water in these individuals is faulty. Their brains continue to believe that they are becoming dehydrated, even as their cells become increasingly waterloagged. In these individuals, the hormone of water conservation, andtidiuretic hormone (ADH), continues to be secreted when its production should be turned off. This hormone is a relic of our recent evolution on the arid African Savannah. Once we had developed the capacity to sweat profusely, and thus potentially to warse water at fast rates during exercise, we needed to keep the potential water losses from the kidney to a minimum. ADH was the solution. But for some humans, this solution is faulty. It is exposed when they have access to too much fluid and have been told to drink as much as possible during exercise. Si in these unfortunate individuals, the excessive fluid they ingest in order to avoid dehydration accumulates in the blood, in the fluid surrounding the cells and inside the cells. The increase in their total water body content causes the body's sodium content to fall. Once this happens, water moves into the body's cells, causing them to swell. It's quite obvious that ingesting even more fluid in this state will only worse the problem..."

You had me at hyponatremia...
