How people decide to consume alcohol when feeling stressed with Jonas DoraHow people decide to consume alcohol when feeling stressed with Jonas Dora
Addiction Audio
Dr Tsen Vei Lim talks with Dr Jonas Dora about how stress affects decisions to drink alcohol, testing the tension reduction hypothesis with a stricter experiment. The conversation looks at differences between starting and continuing drinking, limits of current evidence, and plans for more realistic future studies.

Stress, Sobriety and Drinking Choices with Dr Jonas Dora
Episode Overview
- The long-accepted idea that people drink mainly to cope with stress has less straightforward evidence than many assume.
- In Jonas Dora’s stricter lab experiment, stressed but sober participants chose alcohol more often, even when they liked the alcoholic drinks less.
- Stress did not increase alcohol choice among participants who were already intoxicated, suggesting stress may influence starting to drink more than continuing to drink.
- Daily life data rarely predict how heavy a specific drinking day will be, highlighting the difficulty of understanding within-person fluctuations in drinking.
- Future studies will test similar ideas in more social and realistic settings, including drinking with a friend and enacting actual drink choices.
“We designed this experiment in a way so that the only way to start choosing alcohol more than half of the time is if you start choosing an alcoholic drink you dislike over a non-alcoholic drink you like.”
How do people cope with the challenges of staying sober? Addiction Audio takes a scientific angle as Dr Tsen Vei Lim chats with Dr Jonas Dora from the University of Washington about why stress sometimes pushes people towards alcohol – and sometimes doesn’t. Instead of repeating the familiar idea that “people drink to cope”, Jonas questions how strong the evidence actually is.
He explains the tension reduction or self‑medication hypothesis, then walks through why he felt it needed a tougher test. Earlier lab studies seemed to show stressed people drink more, while daily life studies often didn’t find that pattern at all. That contradiction prompted Jonas to design a stricter experiment. You’ll hear how his team created a 2x2 study where participants were randomly assigned to be stressed or not, and intoxicated or sober.
Everyone first chose between alcoholic and non‑alcoholic drinks until their choices sat at a neat 50/50 split. Only then were stress and alcohol manipulations added, making any later change in choices much harder to explain away. The headline finding? Stressed, sober participants started choosing alcohol more often – even picking alcoholic drinks they liked less over soft drinks they liked more. But when people were already intoxicated, extra stress didn’t push them to drink more.
Jonas stresses that this might mean stress plays a bigger part in starting a drinking episode than in continuing one, while also noting the study can’t answer every “why” or how it plays out in real life. The conversation also covers who took part (regular drinkers, many around the threshold for alcohol use disorder), why predicting how heavy a given drinking day will be is so difficult, and what experiments he’s planning next, including more social and “real‑world” setups.
If you’re interested in how stress, decision‑making and drinking behaviour interact, this research-focused episode offers plenty to chew over without overpromising on clinical answers just yet. How might your own stress‑drinking assumptions hold up under this kind of scrutiny?
