The period of study and/or vocational training coincides with the phase of life where a large proportion of psychiatric disorders emerge. It is therefore common to be asked by a young person in training to make adjustments to his or her training for psychological reasons. Some disorders that were thought to occur in childhood also exist in adults: this is the case of attention deficit disorder with or without hyperactivity, which must be detected and treated appropriately. The tools available for the treatment of psychiatric disorders are not limited to medication and the usefulness of psychotherapy or physical approaches, for example, is well known. We are less aware of the beneficial effects of exposure to nature and green spaces, which are however solidly supported by scientific studies - and which we should not underestimate.
