Alcohol

If you are like many Americans, you drink alcohol at least occasionally. For many people, moderate drinking is probably safe. But drinking less is better for your health than drinking more. And there are some people who should not drink at all.

Because drinking too much can be harmful, it's important to know how alcohol affects you and how much is too much.

How does alcohol affect the body?

Alcohol is a central nervous system depressant. This means that it is a drug that slows down brain activity. It can change your mood, behavior, and self-control. It can cause problems with memory and thinking clearly. Alcohol can also affect your coordination and physical control.

Alcohol also has effects on the other organs in your body. For example, it can raise your blood pressure and heart rate. If you drink too much at once, it could make you throw up.

Why are the effects of alcohol different from person to person?

Alcohol's effects vary from person to person, depending on a variety of factors, including:

How much you drank
How quickly you drank it
The amount of food you ate before drinking
Your age
Your sex
Your race or ethnicity
Your physical condition
Whether or not you have a family history of alcohol problems
