Physical activity may offset some of alcohol’s lethal harms

This first-of-its-kind study found that for alcohol drinkers, physical activity may decrease the risks of dying both from cancer and from ‘all-cause mortality’ that is, deaths from any cause.

Drinking to belong: Students and low self-esteem

It’s that time of year again, when students old and new are heading to university. Certain behaviors might be expected in the coming months, drinking in particular. Drinking is widespread among student populations, whether for social enrichment or the need to conform. However, many college students experience the darker side of binge drinking; violence, unsafe sex or poor academic performance. New research examines motivations for drinking in students with low self-esteem, finding that these individuals indulge far more than their more confident peers. Read more

People judge their level of intoxication, drunkenness on their peers

While becoming intoxicated can impair brain function and result in poor judgment, a new study by Cardiff University in the United Kingdom finds that people’s perception of how trashed they are is judged in comparison to how drunk they think their peers are, rather than based on how much alcohol they have consumed. Individuals are more likely to underestimate their own level of drinking, drunkenness, and the associated health risks when surrounded by others who are intoxicated. However, people feel more at risk of health implications and are more aware of their own level of intoxication when in the presence of sober people, the study says. Read more

Study pinpoints behavior type linked to binge drinking in young adults

While there are a number of studies on alcohol misuse, most of the research has been focused on the adult population. Alcohol is the most widely used drug among young adults between the ages of 18 to 25. Binge drinking – almost a rite of passage – peaks during the college years. So this begs the question, “Are there specific characteristics associated with high-level binge drinking habits in college students?”  A new psychology study conducted at Florida Atlantic University is the first to delve into the specific subcomponents of inhibition behavior as it relates to binge drinking to help predict who may be at high risk, and to better develop targeted education, intervention, and support programs.
