The Science of Making & Breaking Habits | Huberman Lab Essentials

About this video

Huberman explains the biology of making and breaking habits, framing learning as neuroplasticity: the formation of new neural circuits that make some behaviors more likely and others less. He contrasts immediate goal-based habits with identity-based habits linked to a larger self-image, and cites a 2010 study by Lally finding that forming the same habit took anywhere from 18 to 254 days across individuals. Huberman introduces his term ’limbic friction’ for the strain of overcoming anxious or lethargic states, and recommends placing the hardest habits in phase one, the first 0 to 8 hours after waking, when dopamine and norepinephrine are elevated, while using the later, more serotonin-linked phase for easier, consolidating habits. For breaking bad habits, he recommends immediately following a bad behavior with an easy positive habit, gradually rewriting the circuit’s script.
