Why Drinking with Friends Feels Better: UTEP Study on Alcohol and Mood
Ever noticed that a drink at happy hour with friends feels different than sipping alone at home? You’re not imagining it. A new study from The University of Texas at El Paso (UTEP) might explain why this happens, offering fresh insights into the way social settings can influence how alcohol affects our mood.
UTEP researchers, led by biologist Dr. Kyung-An Han, discovered that social drinking might make us feel more upbeat because of how our brains react in group settings. Their work, which was recently published in the journal Addiction Biology, sheds light on why drinking with others can feel more euphoric and why drinking alone can sometimes lead to feelings of sadness.
What Fruit Flies Teach Us About Social Drinking
Believe it or not, tiny fruit flies played a big role in this discovery. While they might seem like an odd choice, these insects actually share about 75% of the same genes that cause human diseases. That’s why Dr. Han and her team used them to study how alcohol impacts behavior in social versus solitary settings.
The experiment was simple: fruit flies were exposed to alcohol vapor, either alone or in a group. Those in social settings became more active and hyper, much like how people can get more animated after a few drinks with friends. On the other hand, flies that “drank alone” showed only a slight increase in activity.
The Dopamine Connection
So, what’s happening in our brains during these moments? The study points to dopamine, a brain chemical that’s involved in feelings of pleasure and motivation. When the flies were in groups, their dopamine levels seemed to amplify the effects of alcohol, making them even more hyperactive. This mirrors how humans might feel more euphoric in social drinking situations.
The UTEP team also identified that a specific dopamine receptor, known as the D1 receptor, plays a crucial role in this process. This finding is important because the human version of this receptor is linked to Alcohol Use Disorder (AUD), a condition that affected nearly 29.5 million people last year alone.
What This Means for the Future
The research from UTEP offers a new understanding of how our social environment can influence the way we experience alcohol. It could pave the way for better treatments for those struggling with alcohol use, by focusing on the brain’s dopamine system.
Dr. Han and her team are continuing their work, hoping to unlock more details about how the D1 receptor and dopamine system interact during social drinking. Their goal? To help people better understand and manage their relationship with alcohol.
As Dr. Han puts it, “Our work is providing scientific knowledge that could help people live better lives, and that’s why we’re so passionate about what we do here at UTEP.”
