We have all certainly experienced the feeling of well-being that even just walking among the shady branches of trees, in silence, or listening to the chirping of nightingales or the slow rustling of the leaves offers us. A sensation of calm inner serenity pervades us, a kind of spiritual coolness and rational cleansing. The fact that forests and wooded places have always had a power of physical and social protection, of the soil itself from erosion, which improves the climate and leads to atmospheric purification, only broadens the range of prodigious benefits they offer us for free.  Trees release ionized oxygen, which acts and interacts with various other elements and living spaces; green also spreads natural bactericides; trees are precious for our health, and among the many benefits they also have the power to lower blood pressure, improve sleep and enrich blood oxygenation. The forms of therapy provided by nature are many and only now we are slowly rediscovering them, thanks also to the fundamental contribution of Forest Medicine. This practice consists of being in nature, connecting with it through all the senses.  Forestry Medicine is very useful for all people, precisely because plants can provide our body with the necessary fuel for vital needs. The air regenerated by the green, associated with movement, activates blood circulation, increasing red blood cells and facilitating breathing, thus helping those with respiratory and heart problems, tensions, moments of stress, and metabolic slowdowns. The various elements of the wooded environment such as the smell of wood, the sound produced by the flow of flowing water, and, more generally, the landscape give a feeling of relaxation and reduce stress. Immersing yourself in nature can lower blood pressure, strengthen the immune system and help focus and problem-solving skills.  Body, mind, heart, and soul: Forestry Medicine comes to our aid at all levels. Contact with nature leads to healthier eating, more exercise, reducing stress, and increasing the ability to concentrate. The relationship with the natural world is also essential for the development of our own balance. In addition, the trees release volatile substances from their foliage and bark, the terpenes, which have an important function in positively stimulating the immune system. Not to mention that all living beings emit bio-electromagnetic fields and those of trees – even if of low intensity – are biologically similar to those of humans: this is why a walk in the woods can truly represent a recharge of power.
