Revisiting-Think Thursday: Your Brain on Water, Why Hydration Matters!
In this replay of a favorite Think Thursday episode, Molly revisits a deceptively simple yet critically important topic: hydration and brain health. With high temperatures hitting the Northern Hemisphere and many of us enjoying summer activities, this episode is your science-forward reminder to drink more water—for your brain’s sake.
From the cognitive impact of just a 1% drop in hydration to how alcohol interferes with your body’s water balance, Molly explores how vital water is to focus, mood, memory, and even long-term mental wellness. If you’re building a peaceful relationship with alcohol, staying hydrated is not only a tool—it’s an essential part of supporting your brain’s ability to think clearly, manage urges, and feel better overall.
What You’ll Learn in This Episode:
- How your brain is 73% water and what that means for daily functioning
- What happens to your cognition and memory when you’re even slightly dehydrated
- The link between hydration and neurotransmitter balance
- Why drinking water improves your mood and clarity
- The real impact of alcohol on your hydration levels
- Simple, science-backed tips to stay hydrated throughout the day
Key Quote:
“If you don’t think cognition is important, you’re simply wrong. Thinking better is how we feel better—and hydration is one of the fastest ways to support your brain’s optimal function.”
Practical Hydration Tips Covered:
- Start your day with water—even before coffee
- Keep water accessible with a refillable bottle
- Add reminders or tracking tools to make hydration a habit
- Use water as a pacing strategy when including alcohol
- Be especially mindful in hot weather or when active
Why It Matters for Alcohol Minimalists:
Alcohol is a diuretic—so it actively dehydrates you. Staying hydrated can not only help reduce the physical impacts of drinking but also keep your brain in peak condition to manage thoughts, emotions, and urges more effectively. Hydration is an underestimated but powerful support tool on your journey to a peaceful relationship with alcohol.
