Cultivating Optimism: A Daily Brain Boost
Our brains are wired for survival, with a primal focus on fear and anxiety. The amygdala, our brain’s emotional centre, lights up most intensely for these two emotions, a built-in alarm system to keep us safe from danger or harmful substances. However, in modern society, where threats are often less immediate, this innate fear response can be overactive, leading to anxiety about everyday occurrences like emails, presentations, or meetings.
To counteract this inherent negativity bias, neurologist and neuroscientist Dr. Faye Begeti, author of The Phone Fix: How to Transform Your Smartphone Habits, practices a simple yet powerful daily ritual. Each morning, she consciously identifies three things she’s looking forward to. This practice, she explains, is akin to exercising a muscle: the more you engage certain neural pathways, the stronger they become. Anticipation triggers the release of dopamine, a neurotransmitter associated with pleasure and reward. By deliberately focusing on positive future events, even small ones like enjoying a nice coffee or meeting a friend, individuals can build up a positive reserve that helps to balance out the brain’s natural inclination towards negativity. The benefit, she notes, is still reaped even if these anticipated events don’t fully materialise.
Actively Building Memories for a Richer Life
Beyond cultivating optimism, Dr. Begeti places significant emphasis on actively creating and cherishing memories. She highlights the distinction between two types of memory: semantic memory, which deals with factual knowledge, and episodic memory, which involves the narrative of our experiences. While factual knowledge, like that acquired through medical training, is crucial, it can leave life feeling like a blur without the richness of personal stories.
To ensure her life and the lives of her children are not just a collection of facts, Dr. Begeti prioritises building episodic memories by seeking out new experiences. She also encourages her children to actively recall positive moments. Every night, she asks them about their favourite part of the day, whether it was something significant or a small, joyful instance. This practice not only reinforces a positive outlook but also increases the likelihood that these cherished moments will be retained in memory for the future.
The Crucial Role of Deep Sleep in Dementia Prevention
The three cornerstones of brain health, according to Dr. Begeti, are diet, sleep, and exercise. Sleep, in particular, plays a vital role in preventing dementia. The development of dementia is linked to the build-up of abnormal proteins that damage brain regions. A critical function of sleep is the brain’s natural process of clearing these misfolded proteins.
While Dr. Begeti acknowledges that life, especially with young children, can lead to disrupted sleep, she advises against excessive worry. She points out that the years of disturbed sleep, particularly in the context of raising young children, are relatively short in the grand scheme of life. Given that protein build-up can occur over decades, a few years of compromised sleep are unlikely to have a catastrophic long-term impact. The key, she stresses, is to prioritise sleep as much as possible while also managing anxiety, as stress itself can be detrimental to brain health.
Strategic Caffeine Consumption for Brain Health
Caffeine, long recognised for its stimulating effects, has also been shown in recent studies to possess neuroprotective qualities. Dr. Begeti incorporates caffeine into her routine but adheres to a strict cut-off time of 1:15 PM. She explains that even if one can fall asleep shortly after consuming coffee, it often indicates an underlying state of sleep deprivation. Furthermore, sleeping with caffeine in your system can reduce sleep efficiency by as much as seven percent, significantly impacting deep sleep – the stage crucial for removing those harmful misfolded proteins.
To maximise the benefits and minimise potential drawbacks, Dr. Begeti employs a strategy of selective caffeine use. She often opts for decaffeinated coffee, reserving caffeinated beverages for days when she truly needs an extra boost. While decaf may not offer the same neuroprotective advantages, this approach allows for a balanced approach to harnessing caffeine’s potential brain benefits while safeguarding sleep quality.
Embracing the Mediterranean Diet for Optimal Brain Function
Having grown up in Greece, Dr. Begeti is a strong advocate for the Mediterranean diet, believing it to be one of the most evidence-backed dietary approaches for brain health. Her personal commitment to this way of eating involves replacing butter with extra-virgin olive oil, preferably sourced from Greece, and embracing a pescetarian diet. She highlights the brain-boosting benefits of consuming two portions of oily fish per week, alongside a wide array of colourful fruits and vegetables. A daily Greek salad, featuring feta, olive oil, and bread, has often provided her with sustained energy during long hospital shifts.
Another valuable dietary guideline she follows is aiming for at least 30 different plant-based foods each week to promote dietary diversity. She actively seeks out unfamiliar items on menus when dining out, ensuring a broad spectrum of nutrients for her brain.
The Five-Minute Rule: Overcoming Procrastination
Dr. Begeti employs the “five-minute rule” to tackle tasks she tends to avoid. This strategy acknowledges the prefrontal cortex’s tendency to amplify the perceived difficulty of tasks when fatigued, as a protective mechanism for mental energy. By committing to doing an undesirable task for just five minutes, she finds that the initial barrier often dissolves. The majority of mental energy, she observes, is expended in the act of starting.
Don’t Neglect Hearing and Blood Pressure Checks
Regular hearing tests and blood pressure checks are inexpensive yet vital health screenings. Uncontrolled high blood pressure, often asymptomatic, can directly damage the brain. Despite comprising only two percent of the body’s mass, the brain consumes a quarter of the body’s blood flow. Prolonged high pressure can lead to vascular damage, increasing the risk of vascular dementia and vascular Parkinson’s disease. Treating high blood pressure can prevent a significant percentage of these conditions.
Similarly, untreated hearing loss is a substantial risk factor for dementia. The positive news is that correcting hearing loss can restore cognitive function to a baseline level. Dr. Begeti herself uses specialised earplugs in loud environments to protect her hearing while still being able to engage in conversations and enjoy music.
Gratitude: A Powerful Lesson from the Medical Field
Perhaps the most profound lesson Dr. Begeti has learned from her demanding profession is the value of gratitude. Witnessing patients whose lives are irrevocably altered by illness or injury has instilled in her a deep appreciation for the fundamental aspects of well-being. Even after exhausting hospital shifts, she finds herself grateful for the simple abilities that are often taken for granted: the capacity to walk, speak, think, remember, and drive. This perspective underscores the importance of appreciating the basics, which form the foundation of a healthy and fulfilling life.
