Lifestyle interventions and their influence on the psyche

The number of patients with mental illness and thus the burden on the healthcare system is steadily increasing, which is why science is increasingly focusing on this topic and alternative treatment methods. Inactivity is the biggest risk factor for countless diseases, which is why physical activity has become a constant companion of science in the treatment of mental illness (Deslandes et al., 2009). Various studies have shown that lifestyle also influences mental health. In addition to physical activity, cultural activities, limiting alcohol and nicotine consumption, reducing BMI to a normal range, and a healthy diet are also promoters of mental health. It has been shown that the above-mentioned lifestyle changes reduce depressive symptoms and anxiety and also lead to increased life satisfaction and self-esteem, which in turn contributes to mental health (Velten et al., 2014).
