Insights from a Brain Fitness Expert

What if the most powerful performance tool available to your team isn’t a new software platform or a productivity system — but their own brain?

NSB speaker Jill Hewlett, Brain Fitness Expert, Wellness Authority, and Brain Gym® consultant of over two decades, has built her work around exactly that question.

Drawing on user-friendly neuroscience and practical brain fitness strategies, Jill equips audiences with the tools to move from stress and cognitive shutdown to clarity, creativity, and peak performance — in minutes, not months.

Here are five brain fitness principles at the core of her work:

1. Your brain can be improved at every age and stage of life

   One of the most powerful — and most underestimated — facts in neuroscience is that the brain is not fixed. Neuroplasticity, the brain’s ability to restructure, grow new cells, and form new neural pathways, is available to all of us regardless of age. Central to Jill’s work is this cornerstone idea: you are the sculptor of your own brain. No one else can do it for you, but the science confirms that consistent, intentional practice creates measurable, lasting change in how your brain functions.

2. Stress is the single biggest threat to workplace cognitive performance

   When the brain perceives stress — whether real or imagined — it triggers the sympathetic nervous system’s fight, flight, or freeze response. The result is a shutdown of executive functions: the higher-order cognitive skills that drive everything we value at work — clear thinking, decision-making, creativity, memory, and strategic planning. Jill’s framework identifies three forms of stress every leader should recognize: acute (normal and temporary), episodic (a red flag requiring attention), and chronic (ongoing and damaging). The leadership implication is significant: a stressed team is a cognitively compromised team, and the fix doesn’t require a wellness overhaul — it requires daily, accessible tools.

3. Awareness is a superpower — and it’s the first step to change

   Before any strategy can work, awareness must come first. A central theme in Jill’s presentations is that the moment we become aware of our brain state, our brain literally begins to shift. Awareness activates new neural trajectories. It moves us from autopilot and reaction into conscious, intentional response. For organizations navigating change, this is foundational: leaders who help their teams build self-awareness are building stress resilience and cognitive agility at the same time. As Jill puts it — we don’t have time not to ask “how is my brain doing right now?”

4. Movement is medicine for the brain — and it takes less than two minutes

   Every brain fitness strategy in Jill’s framework involves movement — and the science behind this is robust. Physical activity improves brain oxygenation, increases cerebral blood flow, stimulates neuroplasticity and neurogenesis, releases BDNF (often called “miracle grow for the brain”), and activates the brain’s happy neurochemicals: dopamine, serotonin, and endorphins. Crucially, this doesn’t require a gym or a lunch-hour run. Jill’s three-dimensional brain fitness movements — targeting the physical, emotional, and higher-order cognitive dimensions of the brain — can be done at a desk in under two minutes. Small, intentional actions that unlock outsized results.

5. Daily two-minute brain boosters create compounding cognitive returns

   The daily two-minute brain booster: A simple pre-check to notice your current brain state, followed by hydration, a short movement sequence, and a post-check to measure the shift. Done consistently, these micro-practices build new, healthier neural pathways that over time become your brain’s new normal. The compounding effect is real: immediate results from a single practice, and extraordinary cumulative gains with consistent practice. For organizations looking to address the projected rise in mental health challenges and cognitive decline in the workforce, this is a practical, evidence-based starting point.

The workplace wellness takeaway:

The brain is your team’s most important performance asset — and most organizations are leaving significant cognitive potential on the table. Jill Hewlett’s brain fitness framework offers something rare in the wellness space: strategies that are fast, fun, evidence-based, and immediately effective. You don’t need a science degree. You need two minutes and the willingness to invest in what’s sitting between your ears.

As mental health challenges are projected to become the leading cause of workplace disability in Canada by 2030, and with dementia cases expected to more than triple by 2050 according to the World Health Organization, the question is no longer whether organizations should prioritize brain health — it’s how quickly they can start.
