Understanding Habit Formation and Change

Huberman Lab Podcast - Episode on Habits

Introduction

  • Host: Andrew Huberman, Professor of Neurobiology and Ophthalmology at Stanford.
  • Focus of the episode: Biology of habit formation and breaking habits.
  • Importance of habits: Organize behavior, often reflexive actions.

Benefits of Habits

  • Allow for more efficient behavior (e.g., brushing teeth, exercising).
  • However, some habits can undermine health and life goals.

Neuroscience and Psychology of Habits

  • There is scientific literature on both habit formation and breaking.
  • Key concepts:
    • Neuroplasticity: Nervous system changes in response to experiences.
    • Limbic Friction: The activation energy needed to engage in a behavior.
    • Immediate Goal-Based Habits vs. Identity-Based Habits:
      • Immediate goals focus on specific outcomes.
      • Identity-based habits link to a larger sense of self (e.g., becoming a fit person).

Time to Form Habits

  • Common belief: 21 days to form a habit.
  • Evidence suggests it can take anywhere from 18 to 254 days depending on the individual and the habit.
  • A specific study (Lally, 2010) focused on habits like walking after dinner.

Limbic Friction

  • Important for understanding how easily habits can be formed or broken.
  • Involves balancing states of alertness and calm.

Linchpin Habits

  • Certain habits can simplify the execution of other habits.
  • Examples: Enjoyable habits that lead to better sleep, hydration, etc.

Measuring Habit Strength

  • Context Dependence: How habits operate in different environments.
  • Limbic Friction: How much effort is needed to perform a habit.
  • Goal: Achieve automaticity in habits.

Practical Tools for Habit Formation

  1. Procedural Memory Visualization:

    • Mentally walk through the steps of a new habit to enhance likelihood of performance.
    • Helps establish neural circuits associated with habit execution.
  2. Task-Bracketing:

    • Connects neural circuits involved in starting and ending a habit.
    • Helps to embed habits into daily routines across different phases of the day.
  3. Phases of the Day for Habit Formation:

    • Phase 1 (0-8 hours after waking): High levels of norepinephrine, dopamine. Ideal for high-effort habits.
    • Phase 2 (9-15 hours after waking): Dopamine levels taper; good for less effortful habits.
    • Phase 3 (16-24 hours after waking): Important for sleep and consolidation of habits formed earlier.

21-Day Program for Habit Formation

  • Set out to perform 6 habits per day for 21 days.
  • Only expect to complete 4-5 each day.
  • Option to reset every 2 days to gauge progress.
  • After 21 days, assess which habits have become automatic.

Breaking Habits

  • Utilize foundation practices: sleep, nutrition, stress reduction.
  • Identify triggers and introduce new positive behaviors immediately after engaging in a bad habit.
  • Create an open loop by engaging in good habits after performing a bad one.
  • Example: If you pick up your phone while working, immediately follow that with a positive habit like drinking water.

Conclusion

  • Importance of understanding biological mechanisms behind habits.
  • Both formation and breaking of habits require strategic approaches.
