It may seem obvious to many, but advancing technology and a shift towards city-living has seen more and more Australians spending increasing time indoors. And with mental health and stress-related diseases a growing cause for concern, it is unsurprising that medical science has begun to link the two phenomena.
The concept of spending more time outdoors, while a seemingly simplistic notion is now well-documented as a proven way to alleviate stress and enhance overall well-being.
Recent studies have underscored the significant mental health benefits of outdoor activities. According to research published by the American Psychological Association, exposure to natural settings can lower cortisol levels, reduce anxiety, and improve mood. This emerging trend, often referred to as “nature therapy,” is now being embraced by mental health professionals and wellness advocates alike.
Dial The Doc’s Dr Jeremy Allen says that spending time outdoors in nature is not just a feel-good strategy but is backed by significant scientific evidence.
“The positive impact of nature on mental health is rooted in several key factors. Natural light helps regulate the body’s circadian rhythms, leading to better sleep and improved mood. Additionally, the presence of green spaces has been shown to reduce feelings of mental fatigue and enhance cognitive function,” Dr Allen said.
A study conducted by Stanford University revealed that walking in natural environments, as opposed to urban settings, led to decreased activity in brain regions associated with depression. This finding highlights the unique benefits of immersing oneself in nature, away from the hustle and bustle of city life.
So just how important is it to find ways to reduce stress in your life? Very important, as it turns out. Stress is now considered one of the biggest contributing factors for disease and has been linked to a wide range of illnesses including heart disease, depression and diabetes.
One of the most well-documented effects of stress is its impact on cardiovascular health. Research from the American Heart Association indicates that prolonged stress can lead to high blood pressure, arterial damage and increased risk of heart disease. A study published in the journal “Circulation” found that individuals experiencing high levels of chronic stress had a 40 per cent increased risk of developing cardiovascular disease compared to those with lower stress levels.
Dr Allen explains the physiology of stress saying that, “when faced with a stressful situation the body activates its “fight or flight” response releasing hormones such as cortisol and adrenaline. These hormones prepare the body to deal with immediate threats by increasing heart rate, blood pressure and glucose levels. While this response can be life-saving in a short term situation, chronic activation can lead to serious health problems.”
Dr Allen recommends several practical ways to incorporate more time outdoors into your day: “Daily walks, even short walks in a local park can significantly reduce stress levels. Activities like jogging, cycling, or yoga in natural settings combine physical and mental health benefits. In addition, nature hobbies such as gardening, bird watching, and outdoor photography can provide regular opportunities to connect with nature”
“The more time you invest in keeping well, the less time and money you’ll need to spend in the long run on medical interventions,” Dr Allen said.
