Binge drinking is defined by the National Institute on Alcohol Abuse and Alcoholism as drinking enough to reach or exceed a blood alcohol content of .08, which is also the legal limit for driving. This level is usually achieved after four drinks for women or five drinks for men, consumed over 2 hours.

But in addition to increasing the risk of these injuries in the first place, binge drinking also reduces the ability of the body to recover from traumatic injuries. Studies have shown that binge drinking contributes to delaying wound healing, increasing blood loss and makes patients more susceptible to infection.
