The Neurological Power of Positivity: Myth or Fact?

In a world brimming with challenges and uncertainties, the power of positivity has emerged more important than ever, guiding us towards better physical, mental, and emotional well-being. Personally, whenever I’ve been told to “be more positive” or to see the glass “half full instead of half empty”, I argue for the side of realism. However, this realistic approach that is so characteristic to my perspective roots from science… which is why to my surprise, and likely to yours too - beyond optimism’s subjective appeal, neuroscience has unveiled the profound impact that a positive outlook can have on our health, so much so that it can impact our surgical and health outcomes. Today, we dive into the relationship between positivity and our neural architecture, exploring how fostering a positive mindset can catalyze a cascade of health benefits.

The brain responds to positivity. The heart of this neural relationship is the brain- the organ that orchestrates our thoughts, emotions, and behaviors. Neuroscientific studies and research have demonstrated that when we experience any form of positivity, certain areas of the brain ‘light up’, signaling the release of neurotransmitters including dopamine, serotonin and endorphins: also known as “feel-good” chemicals. Certainly, we all know that positivity and the emotional state of happiness are inherently inextricable, however, it’s important to consider the pivotal role that these neurotransmitters play in regulating bodily functions and your mindset - from immune boosting and pain management to stress reduction and cognitive function.

One of the most interesting impacts that a positive mindset has is the ability to reduce stress. As we’ve learned and heard before, chronic stress has the capacity to wreak havoc on our bodies, contributing to a myriad of health problems ranging from cardiovascular issues to compromised immune function. Thus, it seems pretty intuitive to say that the cultivation of positivity can help mitigate the effects of stress. Studies have shown that positive emotions trigger the release of hormones/neurotransmitters that counteract the stress hormones like cortisol, thereby promoting relaxation and bolstering our immune system’s defenses. Clearly, a little bit of optimism never hurts anybody - rather, quite the opposite.

Among one of the more unique and fascinating impacts of positivity is the adaptation of our brain’s neural pathways when we engage in positive thinking and experiences, which forges new connections that reinforce optimistic patterns. This change is attributed to the human brain’s remarkable ability to reorganize itself in response to experience - neuroplasticity. Neurons that fire together, wire together. This rewiring enhances our resilience, allowing us to navigate challenges with greater poise and perspective. You may think that this would be rewiring your brain to see the world through rose-coloured glasses, but in reality, you’re increasing your neural capacity for resilience, self-confidence, and perseverance in the face of adversity.

Much to my surprise, doctors have found time and time again that positivity influences our perception of pain, leads to better health and surgical outcomes, as well as accelerates the healing process. Research suggests that when we maintain a positive outlook, our brain’s pain-processing centers remain relatively less activated, resulting in reduced pain intensity. Additionally, positivity triggers the release of endorphins which act as natural analgesics (pain medications), further alleviating discomfort. When it comes to surgical outcomes, maintaining a positive attitude has been found to significantly enhance results through a dynamic interplay of psychological, physiological, and neurological mechanisms. The aforementioned effects - including the release of stress-reducing neurotransmitters coupled with heightened pain management through endorphin release - foster a conducive environment for optimal immune function, reduced anxiety, faster recovery, and decreased risk of complications. Additionally, a ‘rewired’ resiliently positive mindset fosters better patient adherence to postoperative care, promotes furthermore resilience in coping with challenges, and engages our brain's regenerative processes, collectively contributing to a holistic and improved surgical experience and recovery among patients.

As we’ve now seen, positivity isn’t solely confined to our emotions. In fact, it significantly impacts cognitive function as well. Research demonstrates that positive emotions enhance our ability to problem-solve, think creatively, and make more effective decisions. This cognitive boost is attributed to the optimal functioning of a particular brain region called the prefrontal cortex which is associated with higher-order thinking processes.

The synchrony of these neural effects culminates in a profound impact on our overall well-being and even our longevity. Studies show that those who have a positive outlook tend to lead healthier lives, exhibit relatively improved cardiovascular health, and have a longer life expectancy. The combination of reduced stress, better immunofunction, and consequent healthier lifestyle choices prompted by positive thinking contribute to this existential relationship.

The intricate relationship between positivity and our neural architecture is nothing short of remarkable. As neuroscience continues to unveil the intricacies of this connection, it becomes increasingly evident to us that fostering a positive mindset is a powerful tool for advancing our well-being. With positivity, we not only embrace an enhanced emotional state, but we cultivate a thriving environment among ourselves - one that promotes resilience, healthing, and longevity.
