Practice forest walking (nature immersion) for at least 15 minutes to reduce stress, lower blood pressure, and improve mental health through calm and the color green.

The idea that immersing oneself in a forest reduces stress is strongly supported by science. A large meta-analysis published by Twohig-Bennett and Jones (2018) in *Environmental Research* confirms that exposure to green spaces is correlated with a decrease in cortisol (the stress marker) and blood pressure. Small randomized controlled trials (RCTs) conducted in Japan by Yoshifumi Miyazaki's team also validate the benefits of a simple 15-minute forest walk on relaxation compared to an urban environment. However, attributing Japanese longevity solely to this practice is an exaggerated extrapolation, as it depends on a complex set of factors such as diet and social ties. Furthermore, the direct impact of the color green alone on motivation lacks robust evidence, with benefits deriving instead from the overall sensory experience of nature. Finally, declaring that wild spring water is automatically potable is a risky shortcut for digestive well-being.
