Key messages: 

• Calm your body, free your mind, connect with your wild heart in nature
• In nature we feel less alone, we connect with something bigger
• Playful exercises in nature stimulates flow learning and positive mental health

Which nutrients in nature promote our immune system?

1. • exposure to phytoncides, an ethereal substance secreted by trees and plants that slows breathing and reduces anxiety;
   • exposure to mycobacterium vaccae – a bacterium that naturally lives in the soil and stimulates the happiness hormone seretonine;
   • increased adiponectin – a substance that reduces appetite;
   • negative ions in the air have an invigorating effect;
   • the super vitamin D our body absorbs from sunlight, which helps to reduce feelings of depression [1]

The connection between brain, body and environment
At the University of Essex, eco-psychologists developed the Green Mind Theory to explain why nature is so restorative [2]. For the past fifteen years, they have investigated the effect of green activities on our health. The Green Mind Theory makes a connection between our brain, our body and the environment. The basis for good health and a calm mind is sufficient sleep, a healthy diet and sports/exercise. The mind is linked to our brain and body. Our body is connected to natural and social environments. How our body reacts to those environments affects our health, according to the Green Mind Theory.

Why is this interesting? Using a simple metaphor, the researchers demonstrate the influence our brain has on our wellbeing. They simply divide the brain into the red and the blue brains.

The blue brain
The upper cerebral cortex is slower, voluntary. It is the centre for learning and is the driver of rest and digestion. The upper brain calms and controls the parasympathetic nervous system (our calming or sedation system), which performs all kinds of important repair work on our body. However, it only gets space if nothing else is needed: if the danger has passed, if the hunger has been satisfied. In the blue brain, the attention is open, nothing is crucial and there is room for new possibilities, creativity and connection with the people around us. However, it does not usually switch on by itself, – we have to do something to change modes.

• How I feel?
• How I think?
• How I relate to others?

Nature connection supports growth in all six domains. Interventions in nature support well- being by:

• Creating a safe learning environment by switching on our blue brain;
• Experiencing a more relaxed and positive mindset, as our survival mode can easily switch off in nature – we feel safe, secure, soothed;
• Having a positive sense of identity, which includes knowing and feeling good about ourselves, feeling that we have a purpose and having confidence in the ability to learn and grow as well as experiencing that nature does not judge us, that we are 100% ok just the way we are, that we don’t need to change;
• In nature, everything has its own rhythm, the rhythm of the seasons. Nature brings people in contact with their deepest desires and their own natural resources, which they can draw on to live in balance;
• Developing a healthy lifestyle: exercise on a daily basis, eat healthy food, sleep well, recover from stress, find the rhythm to regulate emotions;
• Connecting with the environment, and feel that we are part of something bigger (spiritual dimension);
• Discovering what is really important for us, what our values are, what makes us move and step into action. When we know what our values are, we can keep on taking footsteps on our life path with a purpose in mind – we no longer wander around, feeling lost and not knowing where to go. We feel what is important for us, what change we want to bring in the world, our reason for getting out of bed in the morning.

You may recognize that wild side from when you were a child. How you went on an adventure with your family or friends in nature. Maybe you were a scout and learned survival techniques in nature. Or you went on holiday without a plan and saw where the path was leading you. What is it like now? When do you make room for this wild and free side? This is the cheerful, spirited, funny person you carry hidden within you. The one that is not concerned by the judgment of others and has no self-judgment and is, above all, present. Being, enjoying, in the here and now, with all senses open.

Bring nature in the daily routine
What do you do as a youth worker when your youngsters are tired, stressed and tend to think negatively about themselves? The first step is to bring youngsters in contact with nature. In the review ‘Flourishing in Nature’, the authors examine the concepts of nature contact and nature connection [6]. They found that individuals who are more connected to nature spend more time outdoors, and nature contact often increases momentary feelings of connectedness.

So do put on your coats and go out into nature! Just five minutes of exercise in a park, forest, or other green space immediately improves our mood and self-esteem (Barton & Pretty, 2010). In a meta-analysis, a study of ten English studies about the effect of exercise in a natural environment on mood and mental health, researchers analysed various activities: cycling, walking, gardening, fishing, boating, horseback riding and vegetable garden work.

Their main findings:

• The researchers saw the biggest change in mood and confidence after five minutes of movement in green nature.
• The greatest positive changes in health were found in young people and people with a mental illness.
• All natural environments boost wellbeing, but green areas with water add something extra.
• Whether you exercise intensely or gently, self-esteem and mood increase at all levels.

Sports and exercise scientist Jo Barton of the University of Essex advocates adding more green exercises to healthcare. ‘We know from the literature that positive short-term effects have a protective effect on long-term results’ [7].

• Stage 2. Focus Attention. Attention activities help youngsters become attentive and receptive to nature.
• Stage 3. Offer Direct Experience. By bringing us face to face with a bird, a wooded hill, or any natural subject, Offer Direct Experience activities give us intuitive experiences of nature.
• Stage 4. Share Inspiration. Reflecting and sharing with others strengthens and clarifies the experience. Sharing brings to the surface unspoken but often-universal feelings that, once communicated, allow people to feel a closer bond with the topic and with one another. [8]

So let us provide young people with intense nature experiences in order for them to turn on their blue brain and get in contact with their creativity and positive mood. Activities where we are immersed, without judging, in the here-and-now make us feel intensely alert and alive.

Walk through the forest and experience how wonderful it is to explore the environment with your wild heart, free mind and calm body.
