It is of fundamental importance to make teenagers aware of hygiene habits, both in their bodies and in their diet, and of the benefits and risks that are occurring at every moment in their lives. This book invites readers to realise that good hygiene habits help to strengthen self-esteem, self-care in interpersonal relationships and quality of life. I recommend this book for education professionals, and I wish you all a pleasant read! Lúcia Diógenes.
