It is the amount of alcohol consumed that affects a person most, not the type of alcoholic drink. According to the Dietary Guidelines for Americans external icon , 1 adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to 2 drinks or less in a day for men and 1 drink or less in a day for women, when alcohol is consumed.

Drinking less is better for health than drinking more. Excessive alcohol use includes binge drinking , heavy drinking , any alcohol use by people under the age 21 minimum legal drinking age , and any alcohol use by pregnant women.

Binge drinking is defined as a pattern of alcohol consumption that brings the blood alcohol concentration BAC level to 0. This pattern of drinking usually corresponds to 5 or more drinks on a single occasion for men or 4 or more drinks on a single occasion for women, generally within about 2 hours. Binge drinking typically results in acute intoxication. For men, heavy drinking is typically defined as consuming 15 drinks or more per week.

For women, heavy drinking is typically defined as consuming 8 drinks or more per week. Excessive drinking both in the form of heavy drinking or binge drinking, is associated with numerous health problems, 6 including. There is a strong scientific evidence that drinking alcohol increases the risk for cancer , including cancers of the mouth and throat, liver, breast in women and colon and rectum, and for some types of cancer, the risk increases even at low levels of alcohol consumption less than 1 drink in a day.

The evidence indicates that the more alcohol a person drinks, the higher his or her risk of developing an alcohol-associated cancer.

The risk varies by many factors, such as the quantity of alcohol consumed and type of cancer. The Dietary Guidelines for Americans external icon recommends that adults who choose to drink do so in moderation — 1 drink or less on a day for women or 2 drinks or less on a day for men.

However, emerging evidence suggests that even drinking within the recommended limits may increase the overall risk of death from various causes, such as from several types of cancer and some forms of cardiovascular disease. According to the — Dietary Guidelines for Americans external icon 1 some people should not drink alcoholic beverages at all, including:.

To reduce the risk of alcohol-related harms, the Guidelines recommend that adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to 2 drinks or less in a day for men or 1 drink or less in a day for women, on days when alcohol is consumed. The Guidelines also do not recommend that individuals who do not drink alcohol start drinking for any reason and that if adults of legal drinking age choose to drink alcoholic beverages, drinking less is better for health than drinking more.

There is no known safe level of alcohol use during pregnancy. Women who are pregnant or plan on becoming pregnant should refrain from drinking alcohol. Women of childbearing age should also avoid binge drinking to reduce the risk of unintended pregnancy and potential exposure of a developing fetus to alcohol. Not drinking alcohol is the safest option for breastfeeding mothers. Generally, moderate consumption of alcoholic beverages by a woman who is lactating up to 1 standard drink in a day is not known to be harmful to the infant, especially if the woman waits at least 2 hours after a single drink before nursing or expressing breast milk.

Women considering consuming alcohol during lactation should talk to their healthcare provider. Alcohol use slows reaction time and impairs judgment and coordination, which are all skills needed to drive a car safely. The legal limit for drinking is the alcohol level above which a person is subject to legal penalties e.

All states in the United States have adopted 0. However, drivers younger than 21 are not allowed to operate a motor vehicle with any level of alcohol in their system. Note: Legal limits do not define a level below which it is safe to operate a vehicle or engage in some other activity. Impairment due to alcohol use begins to occur at levels well below the legal limit.

Because alcohol is water-soluble, if two people weigh the same, the person with more muscle and less fat will have a lower blood alcohol concentration than somebody with more fat and less muscle after consuming the same amount of alcohol. Alcohol acts as a central nervous system depressant. This means it slows down the rate at which brain cells and other nerves in the body communicate with one another.

The reason alcohol acts as a social lubricant is because it reduces the functioning of the limbic system of the brain. The limbic system is responsible for producing emotions that drive anxiety and fear. As such, we tend to feel a little less socially awkward after a few drinks. In addition, alcohol reduces the functioning of the pre-frontal cortex — the part of the brain responsible for higher-order cognitive processing including reasoning and judgement.

This leads people to be less inhibited and more impulsive after they have had a few drinks. One danger of this reduction in inhibitions and impaired judgement is that people can sometimes consume more alcohol than they had originally intended. There were studies not too long ago linking certain types of alcohol to longevity and good health, although these could not conclusively make the link between alcohol and a longer lifespan, instead leading news outlets to promote the news based solely off correlation.

Since then, extensive research has been done to study the effects of alcohol on human bodies even in moderation, and the consensus seems to be simple: any alcohol at all will shave time off your life expectancy and will generally negatively impact your health. There are very minor exceptions to this — for example, while moderate or small alcohol consumption still increases the likelihood of heart failure, it is statistically protective against heart attacks.

Something also has to be said for the fact that alcohol is a depressant — this means it helps people relax and unwind, releasing physical and mental tension that, if left unchecked, may lead to something ugly down the line.

Other benefits, previously attributed to red wine, may in fact simply be attributed to the red pigment in grapes and grape juice, rather than the wine.

If looked at objectively, alcohol — more specifically ethanol, also known as grain alcohol — is not something we are meant to ingest. And yet we do, and we often ingest too much of it against our better judgment. The first clue on why alcohol is dangerous lies in how it affects the human mind — while alcohol is a depressant, it also suppresses several functions in the brain, inducing slurred speech, lack of balance, slower reaction times and greatly decreased cognitive ability.

With enough alcohol, the mind loses parts of its memory, leading to mental black outs where entire hours are missing due to heavy drinking. Everything past the drunk stage can be dangerous, leading up to alcohol poisoning.
