The neurobiology of time: Why life moves faster under stress and how to slow it down.
When you look back on early chapters of life (raising young children, building a career, or navigating your twenties) the overwhelming feeling is almost always how fast it all moved. Parents often look back on their children's younger years with mixed emotions: immense pride and joy, but also a quiet wish that they had slowed down to watch one more cartoon or sit through one more game, even when exhausted or busy. When we are in the thick of a demanding phase, our focus naturally narrows to survival mode, getting through the day's tasks, managing schedules, and pushing through fatigue. It is only in hindsight that we realise how fleeting those years actually were.
Why time feels like it’s speeding up.
The sensation of time accelerating isn't just nostalgia; it is rooted in how your brain processes sensory data and stress. When your nervous system lives in a state of chronic busyness or sympathetic ("fight-or-flight") drive, your brain operates on task-oriented efficiency. It filters out sensory details to conserve cognitive bandwidth for whatever task, goal, or problem is immediately ahead. Because your brain stores memories based on novelty and sensory rich details, days spent operating on autopilot blend together. When you look back on a period defined by routine or constant busyness, the brain retrieves fewer distinct temporal landmarks, making years feel like they passed in a blink.
Being present is not about pretending life isn't hard.
Slowing down time isn't about ignoring the exhaustion of parenting young kids, the pressure of a demanding career, or the stress of financial responsibility. Life is genuinely hard, and those seasons are taxing. Being present simply means not allowing the logistics of the day to completely eclipse the micro-moments happening alongside them.
The cortisol buffer: When you are constantly stressed about the next item on your to-do list, elevated cortisol limits your ability to register present emotional connection.
Activating the brake: Taking a moment to pause, unclench your jaw, and take a slow, extended exhalation directly stimulates the vagus nerve. This shifts your nervous system out of task-driven hyper-vigilance and into a parasympathetic state where your brain can actually absorb a moment.
The currency of a well-lived life.
It is easy to get caught up in the chase for milestone achievements; the next career promotion, a bigger home, or financial milestones. But when people reach the later stages of life, the things they treasure are remarkably consistent. Nobody looks back and wishes they had answered more emails or spent more time worrying about chores. They speak of relationships, shared laughter, quiet mornings, and simple moments of connection with the people they loved. We cannot rewind the clock or recreate past years, but we have complete authourity over the moment right in front of us. Put down the phone for an extra ten minutes. Sit on the floor for that extra game. Take a slow breath and let your body register where you are today. Those seemingly insignificant extra moments are ultimately what a life is made of.
