Ep 5: Alcohol and Mental Health Explained - The Hidden Effects of Alcohol

Alcohol is often framed as a way to relax, cope, or “take the edge off”, but what is it actually doing to our mental health?In this episode, we take a deep, evidence-based look at how alcohol impacts depression, anxiety, stress regulation, and the brain’s reward system. We break down how drinking can:Interfere with neurotransmitters like serotonin and dopamineDisrupt the HPA axis and stress hormonesWorsen depressive symptoms and contribute to worsening anxiety And impact our microbiomeWe also explore why alcohol can feel temporarily relieving in the moment while making mood, motivation, and emotional regulation harder over time.We review current research on alcohol use and depression and discuss emerging research on the gut–brain connection, neuroinflammation, and how alcohol-related changes in the microbiome may further influence mental health.Finally, we talk about what it can look like to reevaluate your relationship with alcohol in a compassionate, non-all-or-nothing way. We cover sober-curious approaches, recognizing triggers, building alternative coping tools, and supporting mental health without shame or moralization.This episode is for anyone navigating depression or anxiety who wants to understand how alcohol may be affecting their mental health.Timestamps:(00:00) Intro/Welcome(01:43) Alcohol Trends, Stigma, and Statistics(17:10) Diving into the research.
