Siddharth Warrier: From Infants to Seniors: How Our Brain Impacts Habits | @Sidwarrier

The episode unveils how the brain establishes habits and how these patterns change with age. It explains the dynamic relationship between neurological processes and habit development throughout different life stages. A distinguished guest further enriches the exploration of evolving behavioral patterns.

Started medical training at 18, progressing through MBBS, MD, and neurology specialization completed in 2019. Transitioning from full-time practice during the pandemic led to a journey in content creation. A realization emerged that neuroscience knowledge is essential for everyone to understand the workings of their brain. Emphasis is placed on educating individuals about brain mechanisms and habit-building as the cornerstone of behavior.

Interest in psychology evolved from a fascination with abstract theories, such as hypnosis, to a deeper exploration of human behavior. This exploration revealed that intricate brain networks and chemical interactions underlie thoughts, actions, and habit formation. The journey represents a pursuit of understanding the fundamental biological roots of behavior.

Neurology evolved from viewing the brain as the sole conductor of behavior to recognizing contributions from the spinal cord, brain stem, and even the gut's own nervous system. Historical misconceptions, such as attributing hysteria to the uterus, highlight how outdated ideas have given way to a more nuanced understanding of body functions. Contemporary research reveals that cognition and behavior stem from a distributed network, urging continuous exploration of these complex interactions.

The brain builds habits by repeatedly pairing specific stimuli with automatic responses until conscious choice diminishes. Over time, these learned behaviors become deeply ingrained and shift into reflex actions, such as the knee jerk that operates without thought. This process mirrors an evolutionary pathway where initial learning evolves into efficient, hardwired responses. The transformation from deliberate reaction to automatic behavior underscores the brain’s ability to optimize decision-making through experience.

Human behavior is shaped by learning from painful experiences rather than innate memory, as ancestral knowledge is acquired through trial and error. Burning oneself to learn that fire is dangerous illustrates this lesson, while an ingrained fear of darkness offers greater protection from unseen perils. The warmth and light of fire are favored over the risks of dark environments, and natural reflexes like the pre-sleep jerk test our balance, reinforcing inherent survival behaviors.

New habits begin as deliberate decisions processed in the prefrontal cortex, analogous to the top floor of a building where planning occurs. With consistent repetition, these actions migrate to lower brain regions, becoming automatic like breathing or tooth brushing. Once deeply ingrained, these habits operate with minimal effort and are challenging to alter.

Changing habits relies on three key factors: the attraction to improvement, the urge to avoid negative outcomes, and the constant reinforcement through accountability. The initial pull to achieve goals and the fear of undesirable states drive change, but both fade with time. Sustaining a habit depends on clear accountability measures that keep you on track after initial motivations diminish. Embracing the identity of a healthy, disciplined person ensures that new habits develop naturally and lastingly.

Childhood Emergence of Instinctive and Learned Habits Children enter the world with built-in reflexes, such as the Moro reflex and innate developmental milestones like rolling over and crawling. Their early environment reinforces social cues, trust, and emotional responses as they naturally learn through trial and error. Every interaction offers a chance to form, adjust, and refine behaviors, setting the stage for a lifetime of habit formation.

Neural Pruning: Sculpting Organized Thought Through Habit Formation The brain continuously optimizes itself by trimming unnecessary neural connections, much like a gardener prunes an overgrown tree. This selective removal balances the free flow of creativity with the order necessary for clear, organized thought. By discarding redundant information, the mind focuses on reinforcing the most beneficial habits and pathways for lifelong learning.

The idea that we might run out of memory is a misconception because both our brains and technology continuously evolve to store information more efficiently. Advances such as file compression and SSDs illustrate how more data can be packed into smaller spaces, a process similar to how our biological computers manage information. Ultimately, the varying capabilities among individuals stem from the efficiency with which they compress, store, and interconnect data.

Learning styles are developed as habits acquired from one's environment, not dictated by biology. Individuals in academic settings often create unique methods to quickly memorize extensive information. Modern society's ready access to data shifts focus from rote memorization to efficiently retrieving external information and forging innovative connections between ideas. Historically, when memorization was essential, people relied solely on internal memory to retain vast libraries of knowledge.

Subconscious Filters and Habit Formation The brain constantly absorbs habits, poems, and songs by filtering vast amounts of sensory input. A key player is the thalamus, which screens all senses except smell, allowing only about 10% of information to reach conscious awareness. Unfiltered smells continuously influence us even if we are not aware, subtly guiding behaviors such as hunger.

Developmental Learning Transformed by Curiosity Children absorb information rapidly due to an undeveloped prefrontal cortex, enabling instinctive and expansive learning. As the brain matures, the emerging logic can sometimes hinder learning by imposing self-constraints, though adults can later leverage this system for faster, more analytical learning. Curiosity serves as the prime engine for learning, motivating the brain to work energetically to process, store, and recognize patterns in information.

Intelligence is defined as the ability to spot and utilize patterns across various domains such as numbers, emotions, social interactions, and sports. Different brains exhibit varying capacities in recognizing specific patterns, leading to individual strengths and weaknesses in different fields. While innate abilities reside in the primitive brain, the evolving prefrontal cortex continually refines the control over these basic instincts. This growth illustrates that intelligence is a dynamic process of learning and applying the right patterns at the right time.

The frontal brain enables the suppression of primitive urges like hunger and instinctive reactions. As self-awareness deepens through practices like meditation, individuals can manage even powerful impulses such as sudden aggression. Daily activities, including driving, reinforce this control by requiring constant regulation of natural responses. Remarkably, some people can consciously influence basic functions like breathing and heartbeat, highlighting the profound impact of mindfulness on our inherent instincts.

Children naturally develop habits, yet their brains thrive when faced with just the right level of stress to propel growth without causing overwhelm. A nurturing environment offers a safe space where manageable challenges help foster both habit formation and resilience. Engaging in activities like sports, music, puzzles, or games teaches them to navigate early struggles, gradually uncovering hidden reserves of strength. This balance of gentle push and security builds a solid foundation for enduring personal growth.

An evolved prefrontal cortex in adulthood quickly categorizes new information, offering comfort while obscuring raw patterns. This habit of boxing data limits fresh insights and stifles genuine learning. Overcoming entrenched preconceptions demands critical self-reflection that prioritizes curiosity over the ease of familiar beliefs.

Struggles with self-esteem often leave us entangled in criticism and judgment, blurring our ability to see reality directly. Meditation opens a pathway to observe life without the bias of our entrenched ego, encouraging a clear engagement with the present moment. Emerging research on psychedelics for PTSD and other disorders emphasizes the transformative potential of dissolving rigid preconceptions. The rational capabilities of our prefrontal cortex, while adept at pattern recognition, can also trap us in limiting beliefs that hinder new experiences.

Shared Habits Forge Unified Relationship Identity Individuals in a relationship gradually merge their habits through empathy, perceiving each other as extensions of their own identities. Over time, shared routines like daily rituals and communication styles solidify their bond, making them function as one. The pursuit of new habits can introduce stress or temporary conflicts, underlining the importance of consistent mutual routines.

Ingrained Routines Anchor Life Amid Cognitive Shifts Aging slows brain networks and limits the consolidation of new memories while preserving long-established habits. These ingrained routines, stored in the implicit learning system, enable older individuals to manage daily life despite a fading prefrontal capacity. When familiar practices are disrupted, it triggers significant challenges, emphasizing the critical role of retained habits in stability.

Maintaining brain health through the challenges of aging relies on creating consistent habits that the brain can easily adapt to. Adopting a daily routine, such as sticking to a fixed sleep cycle, nurtures brain function and prolongs cognitive longevity. A sustainable lifestyle and diet, chosen for its long-term compatibility, are more beneficial than erratic changes. The underlying principle is that a steady, habitual approach keeps the brain in tune with its natural rhythm over decades.

Consistent Daily Routines Enhance Brain Health A set of daily habits, such as integrating nutritious choices like eating a walnut every day, builds a solid foundation for brain health. The narrative dismisses the idea of superficial practices by emphasizing real, consistent actions rather than symbolic gestures. It underlines that following effective routines is the best pathway to sustaining mental well-being.

Holistic Life Pillars: Sleep, Movement, Finance, Spirituality, and Adventure Restoring a regular sleep schedule by waking naturally before 6:30 am and ensuring sleep before midnight lays the groundwork for long-term health. Incorporating at least an hour of movement every morning, regardless of the activity, invigorates the body and mindset. Monthly financial reviews foster clarity and strengthen personal relationships, while annual spiritual reflections through the Bhagwat Gita encourage evolving interpretations as life changes. Pursuing scuba diving as a personal passion further deepens the connection to nature and continuous adventure.
