No hangover of hard alcohol (vodka, grain etc.)
My colleagues drink quite like to hard liquor, at times also quite a lot, yet they have the next day rarely an hangovers or if only slightly.
If they contrast drink 2-3 liters of beer a huge hangover. Why is that? Normally one would think but that beer is considerably better tolerated because of its composition?
The best answer
Sure - alcohol causes the kidneys to high excretion of salts and minerals - in beer much more liquid is of course in the game - and the more electrolytes are excreted greater the hangover.
Yes that's true. Should actually be so. But people tolerate different things differently well. So therefore that may well be so. but can change the age or may be a subjective perception also.
