Nature and Mental Health

Why It Matters More Than You Think

Most people already know what it feels like to be in nature, calmer, clearer, a bit more like yourself again. The problem is, when stress is high or life feels heavy, getting outside is usually the first thing that drops off.

The part worth paying attention to….. the research doesn’t just support the feeling it backs it!

Even brief exposure to nature has been shown to reduce stress. One study found that women who simply looked at images of natural environments for two minutes had lower cortisol levels, your body’s primary stress hormone (Hunter et al., 2019). Other studies show that people who walk through natural environments report lower anxiety, less aggression and improved mood afterwards.

This isn’t about doing something extreme like hiking for hours. The shift can start much smaller than that.

the effect of natural environments

At a basic level, humans didn’t evolve in offices, homes or behind screens. We evolved in natural environments. Your brain still responds to that, whether you’re consciously aware of it or not.

Your mind is constantly taking in information and making sense of it. When you’re surrounded by the same controlled, predictable environments every day, such as walls, screens, routines, there’s very little variation. Over time, that can narrow your thinking and keep you in repetitive mental loops.

Nature interrupts that.

Natural environments are unpredictable, detailed and constantly changing. That variation gives your brain something different to process. Research shows this can improve attention, memory and cognitive functioning (Oddie, 2019; Berman et al., 2012).

Put simply, when your environment changes, your thinking has the opportunity to change with it.

What actually changes when you spend time in nature?

The biggest and most consistent benefit is stress reduction.

Spending time in natural environments has been linked to:

• Reduced stress and lower blood pressure (Bush et al., 2016)

• Decreased rumination (overthinking the same problems repeatedly)

• Improved mood and emotional regulation

• Increased sense of control and wellbeing (Chowdhury, 2021)

There’s also something else that often gets missed, decision fatigue.

On average, people make thousands of decisions a day. Many of them feel high-stakes or mentally draining. Natural environments don’t demand the same level of constant evaluation. The choices are simpler and the consequences are lower.

That gives your nervous system a break.

You’re not solving problems. You’re just walking, sitting, noticing. That shift alone can reduce mental overload.

spending more time in nature:

One of the more useful findings in this space is that there isn’t a strict threshold for benefits. There is no “minimum dose”

You don’t need hours. You don’t need perfect conditions. Even short periods of time can have a measurable impact (Robins, 2020).

That matters, because the biggest barrier people report is time.

The reality is, it’s less about adding something new to your day and more about changing where you do what you’re already doing.

This doesn’t need to be complicated or idealistic.

It can look like:

• Sitting outside instead of inside on your break

• Taking a short walk instead of scrolling on your phone

• Having your morning coffee outdoors

• Swapping one gym session for a walk, bike ride or outdoor movement

Modern life is designed to keep your attention constantly engaged, usually in ways that don’t support your mental health long-term.

Studies show that time in nature can improve attention and reduce susceptibility to distraction (Ebata & Izenstark, 2017). That’s not accidental, it’s because nature doesn’t demand your attention in the same way technology does. It allows it to reset.

Research using small daily nature exposure like brief walks has shown increased positive mood and wellbeing compared to those who didn’t include it (Austin et al., 2017).

Consistency matters more than intensity here.

quality of nature matters:

There’s also growing evidence that quality of nature matters. Environments with higher biodiversity, more variation in plant and animal life are associated with greater reductions in anxiety and depressive symptoms (Wyles et al., 2017).

That’s why you’re seeing more green spaces being built into urban areas. It’s not just aesthetic, it’s preventative.

Knowing this is one thing. Doing it consistently is another.

Time in nature is easy to dismiss because it doesn’t feel urgent. There’s always something more pressing like work, responsibilities, things that feel more “productive.”

But this is often the exact point where it matters most.

If it helps, remove the idea that it needs to be done alone or purely through motivation.

Structure it:

• Plan a walk with someone

• Join a group or outdoor activity

• Build it into something you already do

  
  

When it’s scheduled or shared, it’s far more likely to happen.

Spending time in nature isn’t a luxury, or something reserved for when life calms down. It’s one of the simplest, evidence-based ways to support your mental health and it doesn’t require a major lifestyle change.

Even small, consistent exposure can reduce stress, improve mood and help your mind reset.

It’s not about doing more.

It’s about changing the environment you’re doing life in.
