You’ve probably heard that moderate alcohol consumption might protect you from heart disease(1), but that doesn’t mean it’s safe to drink with reckless abandon.
In fact, the research shows that drinking excessively can be harmful to your health.
Here, learn about the risks associated with drinking too much.
! Having one too many drinks at the bar could increase your risk of cancer.
In 2013, researchers for the Annals of Oncology reviewed over 200 studies and found that even light drinking increased the risk of cancer.(2)
In females, light alcohol consumption increased the risk of breast cancer by 5 percent.
Additional research has found a link between relatively low levels of alcohol consumption and breast cancer risk.
In 2011, a study in the Journal of the American Medical Association found that drinking just three to six alcoholic beverages per week increased the risk of breast cancer by 15 percent in women.(3)
Heavier drinking increases cancer risks even further.
In a 2011 study in the Annals of Oncology, researchers analyzed the results of 61 studies and found that moderate alcohol consumption raised the risk of colorectal cancer by 21 percent.(4)
Heavy drinking, defined as consuming four or more alcoholic beverages daily, elevated the risk by 52 percent.

! Regularly treating yourself to a few glasses of wine or mixed drinks could lead to cognitive issues later in life.
In a study in a 2015 edition of The Journal of Gerontology, researchers found that heavy drinking increased the risk of dementia, even after controlling for potential contributing factors, such as lifestyle habits and demographic characteristics.(5)
Additional research has shown similar results.
In a 2015 study in the European Journal of Epidemiology, it was found that frequent drinking, defined as consuming alcohol five or more times during the previous two weeks, increased dementia risk by 45 percent compared to infrequent drinking.(6)
Infrequent drinking was described as drinking one to four times during the previous two weeks.
Increased Blood Pressure
! Heavy drinking could raise your blood pressure, thereby increasing your risk for heart disease and stroke.
In 2010, researchers for the American Journal of Hypertension found that those who consumed more alcoholic beverages per week had higher systolic and diastolic blood pressure levels.(7)
Blood pressure readings were about four points higher among those who consumed at least three alcoholic beverages per week, compared to those who consumed none.
Binge drinking was also associated with higher blood pressure.
A study in a 2013 publication of the journal PLoS ONE also found a link between drinking and increased blood pressure.(8)
Study results indicated that binge drinking one or more times per month increased the risk of high blood pressure by 62 percent in men and 31 percent in women, after accounting for factors such as age, weight, and smoking.
Injury and Death
! Beyond the other health risks associated with alcohol consumption, drinking too much can raise your risk for injury and even death.
In 2015, researchers for The Lancet followed over 100,000 adults for an average of four years and found that alcohol consumption raised the risk of injury by 29 percent.(9)
A recent study in Alcoholism: Clinical and Experimental Research painted an even bleaker picture.(10)
Researchers analyzed the results of five different studies and found that every .02 percent increase in blood alcohol level elevated the risk of a fatal motor vehicle accident by 74 percent.
Shockingly, the risk of a fatal accident was increased by 13 times when the driver had a blood alcohol concentration at the legal limit of .08.
With alcohol increasing the risk of a fatal car crash, it is vital that you use caution if you are going to be drinking.
Arrange for a designated driver ahead of time, or enjoy a beer or two from the comfort of your own home.
To reduce your risk of other health problems, such as;
- cognitive decline
- and high blood pressure
it is important to drink only in moderation.
The National Institute on Alcohol Abuse and Alcoholism recommends that women consume no more than three alcoholic drinks in any given day and no more than seven in a week.
The upper limit for men is four drinks in a single day and 14 in a given week.
Stay within these limits to protect your health, safety, and well-being.
