So many people leading busy, modern lives are running on empty. Between endless to-do lists, constant notifications, fear-driven headlines, and the pressure to always be “on,” it’s no wonder we end up feeling drained, stuck, or permanently in survival mode. The truth is: it’s not your fault. There’s a real reason life feels this way… and once you understand it, you can start making small shifts that make everything feel far easier.
A mismatch between our biology and modern life
One of the simplest ways to explain why we feel so overwhelmed is this: our biology hasn’t changed much since our hunter-gatherer ancestors… but our lifestyles couldn’t be more different.
Humans were designed for a life built around:
- Moving naturally throughout the day (walking, climbing, building, gathering).
- Living in rhythm with daylight and seasons.
- Eating fresh, seasonal food when it was available.
- Relying on a close, supportive community.
Now compare that with modern life:
- Hours sitting at desks, in cars, or on sofas.
- Artificial light and constant screen time disrupting our sleep-wake cycles.
- Food available 24/7 – much of it processed, refined, and far from nourishing.
- Less genuine community connection, with more time spent behind screens.
Our modern-day conveniences have given us many benefits, but often at the cost of our wellbeing. And while having our basic needs met can feel reassuring, that same comfort can also keep us stuck in patterns that work against us when there’s too much of it.
Stress: the central challenge
This mismatch shows up most clearly in how we experience stress.
We’re designed to handle acute stress: sudden, short-lived threats that trigger our fight-or-flight response. Think: escaping danger or facing a one-off challenge. Our ancestors might have experienced this a few times a year, and then (hopefully, ideally) recovered fully.
But what most of us live with now is chronic stress. It’s the myriad of small, daily stressors – physical, mental, emotional, and external – that mean many people never fully come out of a stressed state unless they’re intentional about it.
In other words, we’re living on a continuum of stress. Even if it rises and falls, we rarely reset to zero. Here are some examples across different areas:
- Mental stressors – constant decision-making, information overload, overthinking, perfectionism.
- Emotional stressors – worry, self-doubt, people-pleasing, unresolved conflict.
- Physical stressors – lack of sleep, poor nutrition, too much sitting, over-exercising.
- External stressors – deadlines, the ping of notifications, money pressures, traffic jams.
None of these are life-threatening. But because they come at us constantly, our nervous systems don’t usually get the chance to recover. Instead, we hover in a low-level stress state almost all the time, and that slowly chips away at our mental, emotional, and physical health.
The key thing to remember is that we can’t go back to a hunter-gatherer lifestyle. Some people do try to mimic parts of it – going off-grid, wearing barefoot shoes, or growing all their own food. But that’s not realistic for most of us (and not the kind of approach I focus on in my work).
The good news is: we don’t need a full lifestyle overhaul. There are plenty of small, less drastic ways to live more in sync with our biology, and those simple shifts can make a huge difference to how we feel and live our lives.
The first step in creating positive change is always awareness. When you understand that modern life is wired against your biology, so much starts to make sense. You stop blaming yourself for “not coping” and instead see the real issue: the environment we’re all navigating.
And when you see the bigger picture, you can begin making small, sustainable shifts that:
- Help you manage stress better,
- Protect your energy,
- Improve your mood and wellbeing, and
- Leave you feeling more intentional and in control of your life.
What’s next
This article is based on the very first episode of my new podcast Busy Doing Well. In it, I unpack the mismatch between our biology and modern life, and why stress is such a central challenge for us all.
In Episode 2, we’ll look at stress in more detail – what it really is, the different ways it shows up, and why chronic stress is such a hidden driver of our struggles.
And in Episode 3, I’ll share my ethos: my philosophy on what it truly takes not just to get by, but to thrive and live well in today’s maxed-out world.
From there, we’ll move into a short series on the wellbeing foundations I use in my coaching: food, movement, mindset, time & energy, sleep & rest, and purpose. These first episodes are about creating awareness and form the basis of both the podcast and my work, before we move into more specific, niche topics. Because understanding the root cause is always the first step to real change.
