The Health Benefits of Nature

We’ve all craved nature at some time in our lives. Maybe it was the beautiful white sands of a tropical beach that we longed for, a hike in the woods, or camping trip in the mountains. Whatever our preferences, we all desire nature at some point, and with good reason. Research found that walks in nature reduce blood pressure, adrenaline, and noradrenaline and that such protective effects remain after the nature walk concludes. While exercise is nearly universally recommended as a means of improving overall health and well-being, the benefits of exercising in more natural environments have recently been studied relative to how such activity reduces levels of anxiety and depression.

Mental Benefits

It seems intuitive that we like to spend time outdoors. A 2009 study found that the closer someone lived to a green space or nature area, the healthier that person was likely to be. In fact, those who lived closest to a park, nature preserve or wooded area were less likely to suffer from anxiety or depression. The great outdoors also encourages healthy physical activity, which is a major factor in battling depression. Not only does exercise increase your energy levels and make you physically stronger, but it also makes you feel happier. Movement produces endorphins, the natural chemicals in your body that elicit feelings of pleasure. When you combine the benefits of exercise with the mood-boosting effects of being in nature, you’ll address both the emotional and physical needs of your body.

Grounding

Going barefoot in nature is even more beneficial, as it allows your body to come into direct contact with the earth and truly connect with nature. Getting outside and walking barefoot has been shown to help regulate the nervous system, strengthen immunity, and reduce feelings of stress and anxiety. Nature’s calming effect comes from not only the fresh air, but also the ground. Research done by scientists at the University of Colorado at Boulder shows that Mycobacterium vaccae, a harmless bacteria commonly found in soil, can act as a natural antidepressant by increasing the release and metabolism of serotonin in parts of the brain that control cognitive function and mood. The bacteria can also decrease inflammation in your immune system, thereby alleviating issues from heart disease to diabetes.

Vitamin D

One reason time outdoors may contribute to health is the exposure to Vitamin D producing sunlight. This vital pre-hormone is responsible for many aspects of health throughout the body. Vitamin D deficiency has been linked to various types of cancer, obesity, mental disorders, and other health problems. Getting a doctor-recommended dose of sunlight can also help you feel refreshed and relaxed by helping regulate your body’s melatonin production. Melatonin is a hormone that controls your body’s internal clock (basically, it makes you sleepy). The melatonin-producing part of your brain (the pineal gland) is directly affected by access to light—it remains inactive during the day and is switched on when darkness sets in. The right amount of melatonin ensures you have a good night’s sleep—and wake feeling rejuvenated.

Exposure to nature has been proven to be a key factor in maintaining good physical, social and mental health. The calming effects of the natural environment are particularly beneficial for easing stress, anxiety and symptoms of depression. Getting out into the great outdoors is a habit that you should incorporate into daily life – whether that involves going to the beach, hiking in the woods, going to the local park or simply sitting in your green garden. Regularly reconnecting with the natural world will allow you to live a much healthier, happier lifestyle.
