A common after-effect of alcohol intoxication is the unpleasant sensation known as a hangover, but why do we get a hangover? These symptoms are partly due to the toxic products produced from alcohol digestion and partly due to general dehydration. Dehydration causes the brain to shrink away from the skull slightly. Other components of the hangover are thought to come from the various other chemicals in an alcoholic drink such as the tannins in red wine and the result of various metabolic processes of alcohol in the body. The brain is the organ most sensitive to alcohol. It also receives less oxygen when alcohol is present, which adds to the feeling of fatigue the following morning.
Water on the brain: Grey matter literally shrinks without hydration
Failing to drink enough water can make your grey matter shrink, making it harder to think, experts have warned.
Research shows that dehydration not only affects the size of the brain but also how it works.
Just 90 minutes of steady sweating can shrink the brain as much as a year of ageing, researchers believe
I'm not sure how to post my own comment being new to the site:-) ... could any one help me with a H.BREW qusetion on red wine?? If after secondary fermentation I decide to bottle it, place it in the freezer to kill the yeast and then warm it a little now the yeast is dead. After warming it pace it back into a demijohn and add a hell load of sugar, leave it to rest with a airlock... would I now get sweet wine?? Or would the yeast start to work again and maybe effect flavour.. H.BREW wine is a great idea but it tends to become very bitter and lack the real rich flavour I'm looking for.. could anyone tell me how to reach this flavour without added chemicals, etc:-) :-) :-) :-)
