The Healing Power of Nature

Have you ever noticed how calm and grounded you feel after spending time in a forest, by the sea, or under a big tree? That feeling is not a coincidence—there’s growing scientific evidence showing how nature has a profound and measurable impact on our mental health. From reducing stress and anxiety to improving mood, memory, and sleep, nature offers a deeply healing environment for the human mind and body.

Light, Color, and Mental Health: How Nature Regulates Mood and Sleep

One of the most immediate benefits of being in nature is the effect of light and color on the brain. Nature’s most prominent colors—found in the oceans, rivers, sky, and forests—are in the green to blue-green range of the light spectrum, which happens to be the most critical wavelength for serotonin and melatonin. This spectrum boosts mood and cognitive function and enhances sleep. Loss of contact with blue-green light often happens when we live in urban settings due to overexposure to pavement and buildings, and the destruction of trees.

A landmark study found that surgical patients who could see a cluster of trees from their hospital room window were discharged sooner and required less pain medication than patients whose rooms looked out on a brick wall. More recently, during the acute phase of the COVID-19 pandemic lockdown in 2020, exposure to nature’s blue-green space served as a stress buffer and helped people cope with the lockdown (Pouso et al., 2021).

Similarly, have you ever wondered why you feel so relaxed in the ocean? It is partly because we are exposed to high concentrations of negative ions in the ocean breeze. A negative ion is a molecule that contains an extra electron. These negatively charged particles are created naturally by the sun, wind, and moving water. They make the air cleaner and fresher. Exposure to negative ions also increases serotonin levels in the brain and has a positive effect on mood, learning, and our perception of pain. Negative ions reduce irritability and depression in seasonal affective disorder, suggesting why getting outside daily during the winter months is essential.

These findings support what many people intuitively feel: Nature heals. Whether through a walk in the forest, a day by the sea, or simply sitting under a tree, these experiences nourish the brain and body through multisensory stimulation that cannot be replicated in artificial environments.

Nature as a Privilege: The Unequal Distribution of Green Spaces

In today’s world, where most people live in cities, regular contact with nature is not just a lifestyle choice; it’s often a matter of privilege. Access to green spaces is a sociopolitical issue. In the United States, studies using aerial imagery have shown that affluent neighborhoods have 65% more tree cover than low-income areas. Communities with fewer resources often live among concrete and heat-absorbing infrastructure, with little shade, fewer parks, and more exposure to pollution.

This matters because access to greenery isn´t just about aesthetics; it's a matter of mental health, public health, and equity. Exposure to neighborhood green space is related to lower levels of depression, anxiety, and stress. Addressing these disparities is essential for health equity and social justice.

Still, even in dense urban environments, all is not lost. By acknowledging the systemic nature of “nature deprivation,” we can validate people’s barriers while also offering realistic, hopeful strategies for reconnection. This is where ecotherapy becomes a powerful tool.

Ecotherapy: Restoring Connection and Emotional Resilience

Ecotherapy is based on the foundational knowledge that people and nature coexist in an interdependent relationship that is meant to be mutually beneficial. Sometimes referred to as nature therapy, it includes any therapeutic outdoor activity that fosters this connection. Ecotherapy improves mental health by decreasing anxiety, depression, and stress and by increasing our ability to build relationships. It is also found to help with ADHD, chronic pain, recovery from medical procedures, mood, self-esteem, memory, fatigue, and trauma.

Immersing ourselves in the natural world also creates opportunities to experience awe. Awe arises when we are confronted with something vast and beautiful, beyond our understanding, or a source of great admiration. Think of the silence of a forest, the symmetry of a flower, a massive waterfall, or a star-filled sky.

Awe is a powerful emotion in healing, learning, and exploring spirituality and meaning-making. It’s considered one of the most transformative emotions we can experience, and nature is one of the most common sources of awe. Experiencing awe can ease our physical, mental, and emotional suffering. It can enhance trauma recovery, help us endure depression and chronic illness, motivate us to practice self-care, and inspire a “can-do” attitude to reach our goals. In this context, ecotherapy is not just a practice but a mindset—a return to the understanding that we are part of the natural world, not separate from it.

6 Simple Ways to Use Nature as Mental Health Support

The benefits of ecotherapy are available to everyone, regardless of where they live. Here are some accessible practices you can incorporate into daily life:

Create a Nature-Inspired Environment at Home

Start by incorporating more greenery into your living space—houseplants, flowerpots, or even a small container garden can help. If you don't have a backyard, don't worry—window sills, balconies, and sunny corners can be perfect for growing herbs or small plants.

Outdoor Adventures That Recharge the Nervous System

Spending uninterrupted time in nature—away from technology and the city’s noise—can deeply reset your nervous system. Activities like hiking, rock climbing, camping, bird watching, swimming, stargazing, or paddling in a natural body of water offer profound restorative effects.

Small Daily Moments in Nature for a Calmer Mind

Incorporating small, consistent moments of contact with nature can make a difference in your day:

• Step outside in the morning sunlight, without sunglasses, to help regulate your circadian rhythm and improve sleep.
• Eat lunch under a tree or by a water source.
• Pause to notice the textures, colors, and sounds around you. Even five minutes of mindful presence in a natural setting can shift your mood.

Grounding for Anxiety Relief and Emotional Balance

Grounding involves making physical contact with the earth—by standing on it with bare feet, lying on the ground, touching trees and soil, it's a way to absorb the earth’s electrons. This simple practice can help to reduce inflammation, pain, and stress, and it improves blood flow, energy, and sleep (Menigoz et al., 2020). It also improves the overall modulation of the vagal response (Sokal & Sokal, 2011), an important pathway of self-regulation. Finding a few minutes every day to do grounding can have powerful therapeutic effects.

Forest bathing

Forest bathing (shinrin-yoku) is a practice that emerged in the 1980s as part of Japan’s approach to preventive medicine. This practice invites you to mindfully immerse your senses in the forest or a natural setting, slow down, observe, breathe, and simply be.

Community-Based and Environmental Actions: Caring for the Earth and Yourself

Caring for the environment is another powerful way to connect with nature. Activities such as community gardening, reforestation projects, or beach/forest clean-ups strengthen your bond with the earth and with others. Remember, ecotherapy is grounded in the belief that the human-nature relationship is reciprocal. When we care for nature, nature cares for us in return.

Conclusion: Nature as a Daily Dose of Healing

As research continues to uncover the profound impact of the natural world on our mental and emotional health, it becomes clear that nature is a significant resource for healing, stress reduction, and emotional regulation. Whether through awe-inspiring landscapes or micro-moments of green in our daily routines, we can restore balance, resilience, and meaning. In times when much feels disconnected, nature reminds us that healing often begins with reconnection: slowing down, being present, and grounding ourselves in the living world.
