Regardless of how much alcohol someone has consumed, if they observe others to be more drunk, they feel less at risk from drinking more.
Almost 90 percent of American adults drink alcohol at some point in their lifetime, and more than half of all alcohol consumed is in the form of binge drinking.
According to the 2016-2020 Dietary Guidelines for Americans, if alcohol is ingested at all, it should be in moderation, which equates to up to one drink per day for women and up to two drinks per day for men. However, 1 in 6 adults binge drink around four times per month, consuming an average of eight drinks per binge.
Alcohol slows the function of the central nervous system and alters a person's perception, emotion, movement, vision, and hearing. As a person becomes more intoxicated by alcohol, the changes caused in the brain become greater.
New research published in the journal BMC Public Health - indicates that when people are drunk in a bar and surrounded by others who are also drinking alcohol, their judgment of their own drunkenness and the long-term health implications of heavy drinking is measured against how drunk they rate those people around them.
