Walking in the forest offers much more than just an escape: it's a true wellness cure for our bodies. In response to attacks from pests such as processionary caterpillars, trees release substances called phytoncides. These molecules, in addition to protecting the trees, provide notable benefits for our immune system.
Phytoncides are volatile organic compounds produced by trees to defend themselves against pathogenic microorganisms and harmful insects. When a tree is attacked by pests like processionary caterpillars, it increases the release of these substances to repel the aggressor and warn nearby trees of the imminent danger.
This chemical communication strengthens the resilience of the forest ecosystem in the face of threats. For humans, inhaling phytoncides during a forest walk can have significant beneficial effects.
Studies have shown that these compounds increase the activity of NK (Natural Killer) cells, which are essential for fighting infections and abnormal cells.
Additionally, phytoncides help reduce cortisol levels, the stress hormone, promoting relaxation and well-being.
Processionary caterpillars, particularly those of the oak tree (Thaumetopoea processionea), are defoliating insects that feed on tree leaves, compromising their health and growth. In response to this attack, trees increase the production of phytoncides to defend themselves.
It is essential to remain vigilant against processionary caterpillars, especially in areas infested with these pests. Their stinging hairs contain a toxin called thaumetopoetine, which can cause allergic reactions, skin irritations, and respiratory issues in humans and animals, particularly dogs. Natural behaviors such as sniffing the ground, licking, or biting expose them to this risk.
To fully benefit from the positive effects of phytoncides while minimizing the risks associated with processionary caterpillars, here are some recommendations:
• Stay informed: Research the periods of activity of processionary caterpillars in your area and avoid infested zones during these times.
• Be vigilant: Watch for the presence of nests or caterpillars during your walks and maintain a safe distance.
• Protect yourself: Wear covering clothing to limit the risk of contact with the stinging hairs.
By following these precautions, you can safely enjoy the benefits the forest offers to your immune system while respecting this complex and interconnected ecosystem.
