New year, new goals… but why do so many resolutions fade by February? 🤔 In this episode of Healthy & Litty, Nandita and Mila break down the science behind habit formation and why motivation alone is not enough to create lasting change.
Using evidence-based research, we explore how habits form through neuroplasticity, how the brain responds differently to short-term rewards versus long-term goals, and why dopamine is more about anticipation than effort 🎯. We also debunk the “21-day habit” myth and explain what research actually shows about how long habits take to stick ⏳.
Finally, we discuss how stress, sleep, and emotional regulation impact self-control and decision-making, and what this means for building realistic, sustainable goals 🛌🧘♀️.
Whether you are a student, healthcare provider, or simply working toward healthier habits, this episode offers science-backed insights to help your goals last beyond January 💚🎙️
