You Can Learn New Habits Very Fast: Brain Circuits Rewire Faster With Urgency …more

original sound — @hubermanlab

what it claims

The speed at which a new habit forms depends directly on its level of urgency or necessity, as the brain can remodel its circuits much more quickly under the effect of pressure.

mixed

The concept that urgency accelerates brain plasticity is based on well-documented neurobiological foundations.

The concept that urgency accelerates brain plasticity is based on well-documented neurobiological foundations. Fundamental research, such as the experimental study by Kilgard and Merzenich (1998), shows that intense stimuli release neuromodulators (such as acetylcholine) that accelerate the reorganization of brain circuits. Furthermore, the release of epinephrine during critical situations promotes rapid encoding of essential behaviors. However, applying this urgency mechanism to daily wellness habits is a significant extrapolation. The landmark study by Lally et al. (2010) shows that in a normal context, the automation of a habit takes an average of 66 days of constant repetition. Urgency can force an immediate change, but establishing a fluid and natural routine generally requires time.

Intermittent fasting is only effective for weight loss if it results in a reduction of total caloric intake. However, meal timing matters: eating earlier in the day optimizes fat utilization, while avoiding food intake immediately before sleep stimulates growth hormone production and improves sleep efficiency, thereby allowing one to get by on less sleep.

Slight sleep deprivation distinctly disrupts hunger and satiety signals in men and women, promoting weight gain that is explained by both increased hunger and a decrease in daily energy expenditure.

holds upAndrew Huberman, Ph.D.

To optimize learning and stimulate brain plasticity, it is appropriate to follow an active process: maintain a state of wakefulness and alertness, focus your attention intensely, and accept the mental agitation caused by your own errors, because these are what signal to the brain that it needs to adapt.

Other advice in the Register that leans on the same research.

To successfully change your lifestyle in a sustainable way, it is better to set modest goals and lower your expectations in order to create habits that are sustainable over the long term, rather than aiming for radical and unrealistic changes from the start.

holds upDr Julie Smith

Building your morning routine brick by brick — one new habit at a time, anchored to a habit you already do automatically, tailored to what actually works for you — is the best-supported approach in behavior-change research, far more so than trying to overhaul everything at once.

To successfully commit to exercise for the long term, one must reject the pursuit of rapid results and guilt-inducing comparisons on social media in favor of patience, consistency, and the acceptance of ups and downs.
