Key takeaways from ‘Switch On Your Brain’

1Your choices change your brain
Your choices have a profound impact on your brain at every level, from molecular to electromagnetic, even subatomic. Through thoughts and decisions, we can shape our brain’s circuits like brain surgeons.
These choices act as signals that influence our brain and body, independent of our genes. Epigenetics, an ancient science found in the Bible, reveals how thoughts and decisions affect our physical brain, mental health, and spiritual growth. These choices not only impact us but also the people we are connected to, potentially influencing future generations.
While generational patterns can persist, our minds act as the epigenetic factor, allowing us to break free from negative cycles through conscious choices and their expression adjustments.
Scientists now understand the brain’s remarkable ability to reorganise throughout life through neuroplasticity. Thinking alone can change the brain’s structure and function, presenting opportunities and challenges based on what we focus on.
2Cease milkshake-multitasking
Multitasking involves rapidly shifting attention between tasks, leading to two negative outcomes: reduced focused attention on specific activities and a sacrifice in the quality of our attention. This pattern of multitasking creates flightiness and lack of concentration, potentially resulting in unnecessary medication. The constant focus on social media and information overload prevents us from enjoying the present moment, causing bombardment rather than stimulation.
Milkshake multitasking impairs our attention, making it harder to focus on our thought habits, leading to shallow judgments and passive mindlessness. On the other hand, deep intellectual thinking positively activates the prefrontal cortex, enhancing concentration, minimising distractions, and improving task switching, emotional stability, and overall job completion.
3Capturing our thoughts is essential for brain health and function
Catching our thoughts is essential for calming our spirits and tuning in. Research from the 1970s highlights the significant impact of disciplined introspection on our feelings and thoughts. Purposefully catching our thoughts can positively influence brain processes like sensory processing, rewiring, neurotransmitters, genetic expression, and cellular activity.
An uncaptured chaotic mind filled with anxiety and worry sends negative signals even to our DNA. By spending 5-16 minutes daily in focused meditative capturing of thoughts, we shift frontal brain states, making them more engaged with the world and leading to a happier outlook on life.
