There is good news out here for people under the impression that alcohol kills brain cells. In fact, the consumption of alcohol doesn’t ‘kill’ brain cells, rather it just makes the new cells grow less quickly. The fallacy that alcohol kills brain cells go as far back as the early parts of the 19th century when temperance campaigners wanted to have all types of alcohol banned.

Scientists have done studies with both alcoholics and non with the results showing no difference between the overall numbers of neurons in either group of people. Other studies have actually shown that moderate drinking can in fact improve overall cognition and there was even a study done in Sweden that showed mice who were given alcohol grow more brain cells than those that were not.

Your brain feels nothing, even if you stuck a knife in it, so a hang over is not physically your brain hurting. A hang over comes from your brain shrinking from dehydration causing tugging on the covering membrane which is what becomes sore.
