Nature provides a sense of well-being through various factors: the pleasant fragrance of wild flowers and the calming sounds of leaves rustling in the wind. However, there's more to it than just these sensory experiences.
In today's chaotic and stressful lives, our generation spends significantly less time outdoors compared to previous generations. While being indoors may not directly cause stress, it deprives us of the beneficial effects of nature. Let's explore these effects:
-
Boost to the immune system: Plants release phytoncides, airborne chemicals that have antibacterial and antifungal properties. Breathing in phytoncides stimulates our immune system, leading to increased production of natural killer cells (NK). These cells eliminate infected cells and even cancer cells. Since humans have evolved alongside trees, it's likely that these airborne chemicals have profound effects on us. The immune-boosting effects of phytoncides can last for several days, making it beneficial to spend time in forests or parks at least once a week.
-
Lower blood pressure and stress hormones: Research has shown that walking in a forest significantly decreases blood pressure and reduces levels of cortisol (stress hormone) and adrenaline. Forest bathing trips have the potential to alleviate anxiety, depression, anger, confusion, and fatigue.
-
Improved focus: Certain plant fragrances can relax the cognitive part of our brain, allowing us to direct our mental energy toward tasks and enhance our focus. While access to trees and parks may not always be possible, essential oils can replicate this effect. Since fragrance preferences are genetically influenced, finding the right scent, such as lavender, can greatly aid concentration.
- Increased creativity: Nature has historically inspired great minds, leading to remarkable ideas and creations. Beethoven found inspiration in rocks and trees, Wordsworth composed while wandering over the heath, and Nikola Tesla conceived the electric motor while visiting a park. Nature's ability to enhance focus and creativity likely contributes to these experiences.
So when we talk about nature, we refer to an environment where we can benefit from substantial amounts of phytoncides and other stimuli that relax our cognitive brain, lower blood pressure, and reduce stress hormones. In simpler terms, spending time around trees is good for us.
