Can Trees Really Improve Your Health, or Is That Just a Myth?

The science and value of spending time around trees, explained

In today’s fast-paced world, stress, fatigue, and digital burnout have become a daily struggle for many of us. But the solution to restoring our energy and focus may be much closer than we think: just outside the front door.

Spending time in green spaces, especially areas with trees, has been proven to improve everything from mental clarity to physical health. Trees play a direct role in how we breathe, think, feel, and connect with others.

Here’s a closer look at how trees support our well-being and why time spent in their presence is far from wasted.

1. Oxygen, Air Quality & Lung Support

Trees produce oxygen and help filter the air we breathe. Through photosynthesis, they absorb carbon dioxide and other pollutants, releasing clean oxygen back into the atmosphere.

When we spend time under a tree canopy, whether in a forest, a park, or our own garden, we breathe in cleaner, more oxygen-rich air.

This supports respiratory health, improves energy levels, and can even help relieve symptoms related to asthma or pollution exposure.

2. Reducing Stress & Mental Overload

Trees are calming by nature (literally). A growing body of research shows that time spent near trees lowers cortisol levels (the body’s main stress hormone), reduces anxiety, and improves mood.

Simple things like the sound of leaves rustling, filtered sunlight through branches, or the scent of bark and soil can instantly calm the nervous system. This practice, often called "green time" or "nature immersion", is now being used globally to support people dealing with stress, burnout, and even depression.

3. Physical Health & Immune Boosting

Trees release natural compounds called phytoncides; tiny airborne particles that have been shown to enhance human immune function.

Regular exposure to these compounds can help reduce blood pressure, improve heart rate variability, and stimulate the immune system.

Even light outdoor movement like walking in a tree-rich area has long-term benefits for cardiovascular health and mobility, no gym required!

4. Sharper Focus & Better Memory

Mental fatigue is common in environments that overstimulate the brain, such as cities, offices, or screens.

But wooded or green areas have the opposite effect.

Just 20 minutes among trees has been shown to improve concentration, restore short-term memory, and support problem-solving skills.

This “reset effect” is especially valuable for students, professionals, and anyone needing to recharge.

5. Mindfulness in Everyday Moments

Trees have a way of slowing us down. The textures, colours, and patterns found in bark, leaves, and roots naturally draw our attention and bring us into the present moment.

This practice of being grounded in nature (without distractions) is linked to higher levels of emotional stability and long-term happiness. Mindfulness outdoors is increasingly used as part of therapy for anxiety, PTSD, and general well-being.

6. Connection & Community

Whether it’s a shaded park, a quiet garden, or a tree-lined hiking trail, green spaces bring people together. Trees often frame the backdrop for birthdays, weekend braais, kids’ playtime, or moments of reflection.

They help create shared experiences that build relationships and support emotional health. Even planting or caring for a tree can foster a sense of purpose and stewardship, both of which are important for mental health.

Final Thoughts

Trees are essential to our daily lives. They improve the air we breathe, reduce stress, support our immune system, and help us reconnect, both with nature and with ourselves.

If you live in a town or suburb with trees, spend more time around them. And if your trees need care to stay safe, strong, and thriving, that’s where we come in.
