To raise students’ awareness of sleep as a healthy behaviour, our school invited Dr. Wong Hiu Lei, a specialist in pediatrics, to deliver a school assembly on cultivating good sleeping habits on 26 September. Dr. Wong is a former President of the Hong Kong Paediatric Society. She currently serves as the Secretary General of the Hong Kong Paediatric Foundation and a member of the Commission on Children. She has also held positions including the Regional Vice President of the International Association for Adolescent Health (IAAH) and President of the International Chapter of the Society for Adolescent Health and Medicine (SAHM), actively promoting the health of children and adolescents. Dr. Wong’s presentation was informative and accessible, greatly benefiting the students.
