HYP, observing and recognizing the ever-increasing mental health challenges faced by young people across Europe, responded to the need and created “Breathe”. According to the Eurobarometer/October 2023, 46% of respondents face mental health challenges such as anxiety and depression without being able to get the support they need. Especially in adolescence, the numbers are remarkable: according to the WHO, one in seven people aged 10-19 suffers from mental disorders. At the same time, at a global level, depression is the 4th most common cause of illness or disability for people aged 15-19, while anxiety is the 9th most common cause in the same age. At the same time, suicide (which is directly linked to mental health) is the 4th most common cause of death among adolescents worldwide. BREAKTHREE recognised the need for a holistic approach, taking into account the mind-body connection, the importance of developing emotional intelligence and the impact of effective communication on mental wellbeing. The needs assessment phase for the HYP audience and project partners helped us understand the specific challenges young people face in each participating country, ensuring the project is tailored to address the unique circumstances and concerns of each community. The central idea of the project was to train youth workers and educators working with adolescents to equip them with the relevant knowledge, skills, and attitudes to use nature-based activities that promote mental wellbeing. The project examined the interconnection of body, emotions and communication to support mental wellbeing. NEEDS OF YOUTH IN PARTNER COUNTRIES In all partner countries, mental well-being issues are closely linked to social exclusion, loss of social contacts and sociability, as shown in the analysis in The Effect of COVID-19 on Youth Mental Health. In this context, the need to strengthen the resilience and mental well-being of young people, especially adolescents, emerged, which was verified through Breathe. NEEDS OF PEOPLE WORKING WITH YOUTH: Through our research, we saw that people working with youth most often do not have psychological training, but are often called upon to take on roles and actions that are directly related to the mental well-being of young people. At the same time, these people often experience burnout caused by the various roles and responsibility they have towards young people in connection with limited training. Furthermore, youth workers themselves have noted as problematic the increasingly limited contact of young people with nature and the corresponding attachment to the digital world. Taking all of the above into account, this project aims to increase the capacity of individuals and educators working with youth (mainly adolescents) to strengthen the mental well-being of their groups, mainly with nature-based methodologies. OBJECTIVES of Breathe were: 1. Better understanding of the concept of mental well-being and the factors that hinder and promote it, respectively, by 24 people working with youth (especially adolescents). 2. Development of competences (knowledge, skills, behaviours) in relation to the creation and implementation of nature-based activities that enhance mental well-being, centred on the interconnection of body, emotions and communication. 3. Strengthening the motivation of youth workers to address mental well-being and nature connection in the activities they implement. 4. Developing a European support network of youth workers and educators from different backgrounds, with everyday needs and interests. 5. Creating at least 10 innovative nature-based activities to promote mental well-being with a focus on the interconnection of body, emotions and communication.
