There is a growing body of research that suggests that nature connectedness, or the sense of connection and relationship that individuals have with the natural world, is positively related to well-being. This can include physical, mental, and emotional well-being.

Studies have shown that spending time in nature, or even viewing nature scenes, can lead to reductions in stress, anxiety, and depression, as well as improvements in mood, cognitive functioning, and overall well-being. Engaging with nature can also lead to a greater sense of self-esteem, self-worth, and overall life satisfaction.

Nature connectedness is also associated with physical health benefits, such as lower blood pressure, improved heart rate variability, and improved immune function. Furthermore, being in nature can also lead to increased physical activity, which is known to be beneficial for overall health and well-being.

The Connectedness to Nature Scale (CNS) is a psychological measure developed by Mayer & Frantz (2004) to assess the extent to which individuals experience a sense of oneness with nature, recognize the interconnectedness of all living things, and perceive nature as a source of beauty and spirituality. Empirical analysis shows that high CNS scores are linked to pro-environmental behaviors and increased subjective well-being.

The Nature Relatedness (NR) scale, developed by Nisbet, Zelenski, & Murphy (2009), evaluates the emotional, cognitive, and physical connection that individuals have with the natural world. According to empirical analysis, individuals with higher NR scores typically exhibit traits of openness to experience, agreeableness, and conscientiousness, which are associated with improved emotional and mental well-being.

Some mechanisms that have been proposed to explain the positive effects of nature connectedness on well-being include the restorative effects of nature, the positive impact of nature on the body's stress response, and its positive influence on mood, self-esteem, and overall life satisfaction.

It is important to note that not all people have equal access to nature, so understanding the barriers to nature access, and addressing them, is crucial for promoting nature connectedness and well-being for all.
