Nature and heart health

Context

Humans have an innate connection with the natural world. 1 2 For most of human history we have evolved and lived with the outdoor world, in natural settings. 3


This connection is important for both human and planetary health. 4 Spending time in nature can help lower levels of stress (cortisol), blood pressure and heart rate, and provide opportunities for physical activity and social connection. 5 1 It can also lead to increased care and concern for the environment. 6

However, we are becoming increasingly disconnected from nature. ‘Nature deficit disorder’ is a term used to describe the impact of this disconnection on our health and wellbeing. 7 Poor cardiovascular health is one of many concerns linked to lack of exposure to nature. 8 Where time is not spent in nature, a person does not receive health-mitigating effects to help reduce stress, blood pressure and heart rate, among other benefits.


To turn this around, we need to make nature more available, easier to access, and part of people’s everyday lives. This includes access to green (vegetation) and blue (water) spaces in built and natural environments. Examples in built environments include public open spaces, tree canopy, community gardens, and vertical green walls. Natural environments include forests, mountains, rivers, and coastal environments.


Research shows that spending at least two hours each week in nature provides a wide range of health benefits. 9 Benefits include improved brain function and mental health, and lower blood pressure, heart rate, and cortisol levels. 1


There are many actions we can all take as built environment industry practitioners, healthcare providers, and community members to improve access and connection to nature.

 

Physical activity and social connection in nature

Research shows that exercising outdoors can have a greater health benefit than exercising indoors. 3 People may exercise more often and for longer periods of time in natural environments. 3 Appealing and enjoyable spaces can increase motivation and lower levels of perceived effort. 3


In addition to physical activity, social connection is also important for heart health. 10 Nature-based environments provide opportunities for social interaction that may not be achieved in other settings. 1 3 This includes outdoor-specific activities such as picnics and other social gatherings, as well as being able to focus more on family and friends in natural settings. 11 12

 

Built environments

To ensure all people living in Australia benefit from time spent in nature, all urban environments should provide green and blue spaces.


Studies have found a strong link between the cardiovascular health of people who live in walkable urban environments with higher amounts of green space. 13 These areas often tend to be older, established neighbourhoods. 14


In contrast, less advantaged areas and areas of high urban density often have less availability of, and access, to green and blue spaces. 15 16 17 13 18 

 

Natural environments

Time spent walking in a forest can have additional health benefits compared to walking in an urban area. 19 The quality of green and blue spaces where we spend time outdoors is also important: areas with higher levels of biodiversity tend to deliver greater health benefits. 20


Spending time in nature exposes us to a range of microbiota and other chemical and biological organisms. 19 This is thought to be beneficial for health because of the response it produces in our parasympathetic nervous system. This response includes helping reduce and manage levels of stress 1 and improving blood pressure. 19 Forested and mountainous areas, and flowing rivers have high concentrations of negative air ions. 21 This can help reduce anxiety and depression. 8,19


Natural environments also provide opportunities to experience moments of awe (something larger than ourselves). These moments can also provide health benefits. 19

 

Priority populations

Physical activity in green and blue spaces can benefit the health of older people. Examples include community gardening, 22 increased opportunities for walking 18 23 and use of outdoor exercise equipment. Volunteer-led activities enhance these benefits. 24 25


The natural environment is often cited as a major asset for physical activity, particularly walking, in rural and regional areas. 26


LQBTQIA+ people are less likely than other groups to meet physical activity guidelines. 27 One research study in regional Victoria found that when people from this group do take part in physical activity, they are more likely to do so through hiking/bushwalking and in natural settings. These environments are perceived to be more welcoming and inclusive. (De Silva DATE tbd )

 

Environmental behaviours

Spending time in nature can help people connect with and care about the environment. 4 6 28 It can build empathy for the natural world and encourage positive behaviour. This can include actions such as reducing waste, reusing items, and recycling.


These behaviours can help reduce the impacts of climate change. Addressing climate change—such as lowering air pollution and reducing extreme weather—can further benefit heart health. 29 Together, this creates a positive cycle that supports both environmental and human health.

Take action

There are some key actions that we can all take to improve connection with nature for heart health:

For built environment industry practitioners:


Greening urban environments is a powerful, cost-effective and inexpensive public health intervention
