Here's What Really Happens to Your Brain When You Drink Too Much Alcohol


Health l April 24, 2018

Some of the effects, like slurred speech and loss of balance, can be very obvious. Others, like cell death, not so much.

A glass of wine with dinner, a happy-hour beer after work, a cocktail (or three) on vacation: Alcohol is deeply ingrained in American culture, and, for many of us, it’s a normal part of our daily lives.

Studies suggest that alcohol, when consumed at low to moderate levels, may have some health benefits. It can also produce feel-good effects, which is why many of us turn to it in social situations or during stressful times. But the research is also clear about something else: When a person consumes alcohol above and beyond moderate levels, it can have damaging effects on the body and on the brain—both short-term and permanently. Some of those effects, like slurred speech and diminished memory, can be quite clear; others, like long-term cellular damage, may not be as obvious.

If you’ve ever wondered what’s really going on in the brain when a person’s had too much to drink, here’s a brief primer. The experts we spoke with agree: Most people shouldn’t feel guilty about enjoying the occasional drink—but keep these effects in mind if you’re tempted to overdo it.

Wow, totally saved my academic life! I was drowning in my dissertation, and these guys swooped in like superheroes. The quality of the work they delivered was top-notch. It's like they read my mind and put my thoughts into words. Super impressed with the research depth and the flawless writing. Plus, they met my tight deadline. Total stress-buster!

I completely agree with you, my friend, and with the author of this post as well, alcohol and all substances that intoxicate our minds are just poison, so I have not been drinking alcohol or even smoking for a little over three years now. It's good that the Match Center came into my life, because it makes my life much brighter, adds color and everything becomes easier. For example, now I can't play sports in my free time because injuries don't allow me to, so I'm glad that I can at least play like this.

Wow, just a great article, I wish there were more of them on the web, then maybe people would drink less alcohol, because it is such a poison for the brain and the whole body. I have not been drinking alcohol for more than ten years, and I am very happy about this, because a sober lifestyle opens a lot of doors for me, one of these doors was that I found a ninja casino, the best casino I have ever played, a bunch of new games, a reliable and cool system, I recommend it to everyone, it helps me to brighten up my time on weekends, which makes me very happy.
