On the occasion of World Hug Day, psychologist Dr. Aristoniki Theodosiou-Tryfonidou analyzed the beneficial properties of hugging for mental and physical health. Hugging strengthens the immune system, reduces cortisol (the stress hormone), and increases serotonin (the happiness hormone). It is not just an expression of affection, but a biological command for relaxation. Hugging is especially important for child development, helping to organize their nervous system and reduce internal disturbance. Dr. Theodosiou emphasized the need for human connection and the value of hugging in everyday life.
