Question: Why does alchol make you drunk?

Antonia Hamilton answered on 14 Jun 2010:
Alcohol gets into your brain and interferes with the neurotransmitters that send information around your brain. When the neurotransmitters aren’t working properly, you can’t walk steadily or talk coherently and you can’t make good decisions. Some people get aggressive from too much alcohol, others get sleepy.

Alcohol is a sedative, so it makes your brain work more slowly. It’s not unusual for people to be brought to hospital after drinking too much – they either hurt themselves by accident or get into a fight. Too much alcohol can really send people to sleep and most seriously can reduce the brains’ stimulation for you to breathe making that really serious.

Alcohol tends to affect brain function. It can reduce the amount of water in the parts of the brain that we use to think, this reduced water changes how the brain works. Alcohol also affects our Central Nervous System (CNS). The CNS is responsible for controlling our motor functions and our senses. It is quite complicated how this works but basically alcohol interacts with various biological molecules in out bodies either by competing with them or causing the release of various bio molecules at higher levels than normal.
An example of this is when alcohol makes our body release more dopamine. Dopamine is a type of biological compound known as a neurotransmitter. These neurotransmitters regulate the parts of the brain that are associated with pleasure. So increased dopamine results in a temporary increase in the feeling we know as pleasure. Alcohol also affects how our bodies biological functions work, this in turn can change how our bodily functions respond, so our mood, temperature, sleep patters etc can all be changed due to alcohol causing a biochemical imbalance.
