Failing to drink enough water can make your grey matter shrink, 
making it harder to think, experts have warned.


Just 90 minutes of steady sweating can shrink the brain
as much as a year of ageing, researchers believe.

The lack of fluid could impact on performance
at work and school and on exam results. 


Researchers Matthew Kempton and Ulrich Ettinger,
of the Institute of Psychiatry at King's College London, 
scanned the brains of teenagers after an hour and a half of cycling.

Some exercised in three layers of sweat-inducing clothing.
Others were much more lightly clad in shorts and t-shirts.

Those who were wrapped up lost around 2lb in sweat,
and their brain tissue had shrunk away from their skulls. 

The amount of shrinkage equated to 14 months
of age-related wear and tear, or the withering away
associated with two and a half months of Alzheimer's disease.


Researchers said: there is no need to panic,
because after a glass of water or two the brain quickly returns to normal.
However, if the dehydration remains long time,
it can possibly damage the ability of cognizance.

We know it's HOT outside.
