The Psychology of Simplicity and How It Affects Us Every Day

Does busy life often make you feel stressed out and overwhelmed? Do you crave a quieter, slower, simpler life instead? In this article we explore the psychology of simplicity and how it affects us every day.

WHAT IS THE PSYCHOLOGY OF SIMPLICITY?

In a world that constantly demands more—more possessions, more commitments, more productivity—it’s easy to feel overwhelmed. But what if the key to happiness wasn’t in adding more, but in embracing less? Simplicity isn’t just about decluttering your home or cutting back on obligations; it’s a mindset, a way of living that prioritises what truly matters.

When life feels complicated, I tend to crave simplicity and to focus my time, energy and attention on just a few things that are really important. I let the rest go. I always wondered why my reaction to too much was always to seek calm, quiet and comfort in having less – choices, decisions, responsibilities… the list goes on.

Although we can’t turn our backs on much of what life requires of us, it seems that I’m not alone. Many of us look for a simpler way too. Maybe that’s why you’re here reading this right now? Welcome if that’s you, by the way. I’m so pleased you’re here.

Science also supports the idea that a simpler life leads to greater health, happiness, and overall well-being.

By understanding the psychology of simplicity, we can learn how to cultivate a life that feels lighter, more fulfilling, and deeply intentional. In this article I’m exploring the benefits of simplicity, why our brains crave it, and how we can bring more of it into our daily lives.

WHY OUR BRAINS THRIVE ON SIMPLICITY

Our brains are wired for efficiency. Cognitive load—the mental effort required to process information—affects our ability to focus, make decisions, and manage stress. When we are bombarded with excess—whether it’s clutter, an overflowing To Do list, or constant digital notifications—our cognitive resources are depleted, leaving us feeling drained and overwhelmed.

Studies show that too much choice can actually increase stress and decision fatigue. In a well-known experiment, psychologists Sheena Iyengar and Mark Lepper (2000) found that when shoppers were presented with 24 different types of jam, they were less likely to make a purchase than when they were offered only six choices. This phenomenon, known as the paradox of choice, suggests that too many options can lead to anxiety, second-guessing, and ultimately, dissatisfaction.

By simplifying our lives—whether it’s by reducing possessions, streamlining decisions, or creating structured routines—we reduce mental clutter and free up cognitive space for the things that truly enrich us.

THE MENTAL HEALTH BENEFITS OF SIMPLICITY

1. Reduced Stress and Anxiety

Research has shown that cluttered environments can contribute to stress. A study by UCLA’s Center on Everyday Lives of Families (CELF) found that high levels of household clutter were directly linked to increased cortisol (the stress hormone) in mothers. Living in a cluttered space can create a sense of chaos, making it harder to relax and unwind.

By simplifying our surroundings, we create a calm, peaceful environment that signals to our brains that it’s okay to rest. A minimalist space isn’t just about aesthetics—it’s about creating mental clarity.

2. Improved Focus and Productivity

Our attention is a limited resource. The more distractions we have, the harder it is to concentrate. Studies in neuroscience show that multitasking reduces efficiency and increases errors (American Psychological Association, 2006). When we simplify our environment—whether by clearing our workspace, reducing digital distractions, or prioritising fewer but more meaningful tasks—we sharpen our focus and increase productivity.

3. Greater Life Satisfaction

Happiness research suggests that experiences, rather than material possessions, bring greater long-term satisfaction (Gilovich & Kumar, 2015). When we shift our focus away from accumulating things and towards meaningful experiences—such as travel, connection, or creative pursuits—we feel more fulfilled. A simple life encourages us to invest in what brings us genuine joy, rather than chasing external validation.

THE POWER OF SIMPLICITY IN THINKING AND DECISION-MAKING

Simplicity isn’t just beneficial for our physical and emotional well-being—it also plays a crucial role in how we think, learn, and make decisions. The human brain is naturally drawn to clear, straightforward explanations, and research in psychology and philosophy suggests that simpler ideas are often easier to process, remember, and act upon.

One well-known principle that reflects this idea is Occam’s Razor. Named after the 14th-century philosopher William of Ockham, this concept suggests that when faced with multiple explanations for a phenomenon, the simplest one—requiring the fewest assumptions—is usually the most accurate. For example, if you hear hoofbeats outside your window, it’s far more likely to be a horse than a zebra. While complex explanations can sometimes be valid, unnecessary complications often cloud our understanding rather than enhance it.

This principle applies to many areas of life. Take problem-solving, for instance: when making decisions, we often overthink, adding layers of complexity that aren’t necessary. If you’re trying to decide whether to take on a new commitment, a simple guiding question like “Does this align with my values and priorities?” can often provide a clearer answer than a long list of pros and cons.

Simplicity in communication is another key area where less is more. Studies in cognitive science show that people remember information better when it is presented in a straightforward, structured way. This is why great teachers, writers, and leaders often use simple, relatable examples to convey ideas. For instance, the best public speakers break down complex concepts into everyday analogies, making them more accessible and digestible.

Beyond thinking and decision-making, simplifying experiences can also lead to greater enjoyment and meaning. A meal shared with a loved one, a walk in nature, or a quiet evening with a book often bring deeper satisfaction than overstimulating, high-effort activities. The mind processes simple experiences more easily, allowing us to be fully present rather than overwhelmed.

By embracing simplicity in our thoughts, choices, and experiences, we reduce mental clutter, enhance clarity, and make life feel more manageable. Whether it’s resisting the urge to overcomplicate decisions, keeping explanations clear and concise, or choosing simple but meaningful ways to spend time, the principle remains the same: simplicity makes life easier to understand and enjoy.

SIMPLICITY AND PHYSICAL WELL-BEING

1. Better Sleep

A cluttered mind often leads to restless nights. The National Sleep Foundation found that people with clean, organised bedrooms reported better sleep quality. Reducing clutter in our environment and following simple evening habits and routines—such as limiting screen time and embracing bedtime rituals—signals to our body that it’s time to rest.

2. Healthier Eating Habits

Simplicity extends to how we nourish ourselves. Overcomplicated diets and endless food choices can lead to decision fatigue, making us more likely to reach for unhealthy, convenient options. Research suggests that people who simplify and adopt healthier eating habits—by meal planning, eating whole foods, and reducing processed choices—are more likely to maintain healthier lifestyles.

3. Increased Movement and Mindfulness

A simple life naturally encourages more movement and mindful activities. When we aren’t weighed down by excess, we are more likely to take walks, spend time in nature, and engage in slow, intentional activities like yoga, gardening, or journaling. These activities reduce stress, improve cardiovascular health, and enhance overall well-being.

SIMPLICITY AND INTENTIONAL LIVING

Simplicity is deeply connected to intentional living—the practice of making conscious choices about how we spend our time, energy, and resources. When we strip away the unnecessary, we gain clarity on what truly matters.

1. Decluttering with Purpose

Simplifying our possessions isn’t about getting rid of everything—it’s about keeping what adds value to our lives. Ask yourself: Does this item serve a purpose? Does it bring me joy or add value to my life in some way? If not, it might be time to let it go.

2. Creating Space for What Matters

A simpler life makes room for meaningful relationships, personal growth, and rest. When we reduce obligations that drain us and prioritise activities that nourish us, we feel more fulfilled and life feels more meaningful.

3. Slowing Down and Being Present

The fast-paced, productivity-obsessed culture tells us that we should always be doing more. But a simple life reminds us that slowing down is not laziness—it’s an act of self-care. Practising mindfulness, enjoying meals without distractions, and embracing moments of stillness can deepen our appreciation for life.

PRACTICAL STEPS TO EMBRACE SIMPLICITY

1. Start Small

Simplicity isn’t an all-or-nothing approach. Start with one area—your wardrobe, a single room, or your digital space. Small, consistent changes lead to lasting transformation.

2. Limit Your Choices

Reduce decision fatigue by creating routines. Simplify your morning by having a go-to breakfast or a capsule wardrobe. The less energy you spend on minor decisions, the more you have for what truly matters.

3. Declutter Regularly

Adopt a habit of regular, even daily decluttering. Instead of waiting until things feel overwhelming, dedicate a few minutes each week to letting go of what no longer serves you.

4. Be Mindful with Purchases

Before buying something new, ask yourself: Do I really need this? Will it add value to my life? Being intentional with purchases prevents unnecessary clutter from accumulating.

5. Set Boundaries with Technology

Digital clutter can be just as draining as physical clutter. Set limits on screen time, unfollow accounts that don’t inspire you, and take regular breaks from social media to create mental space.

6. Prioritise Rest and Joy

A simple life isn’t just about removing things—it’s about adding what nourishes you. Make time for hobbies, nature, and meaningful connections and relationships.

7. Embrace Imperfection

Simplicity isn’t about perfection—it’s about creating a life that feels aligned with you. Let go of the pressure to do it “right” and instead focus on what brings peace and clarity.

CONCLUSION

The psychology of simplicity reminds us that less is often more. By clearing away the excess, we create space for clarity, joy, and fulfilment. Science backs up what many of us feel intuitively—when we embrace simplicity, we feel calmer, more focused, and more in tune with what truly matters.

If life feels overwhelming, consider what you can simplify today. A clutter-free space, a slower schedule, and a more intentional approach to life might be the key to the happiness and peace you’ve been looking for.
