The Junior Chamber International Peninsula hosted a press conference and opening ceremony for the "Mission RED – Guardian of Sleep" survey at Xiqu Centre, Tsim Sha Tsui. The initiative aims to examine local students' sleep duration and quality, highlight the impact of insufficient sleep on their physical and mental development, and raise parental awareness of the importance of "sleep hygiene."
Survey findings reveal that 83% of Primary 1–6 students average only 8.8 hours of sleep per night, significantly below international standards. Experts warn that inadequate sleep can impair children's emotional regulation, immunity, and long-term growth, urging parents and schools to take immediate action.
Conducted between February and March 2026, the survey interviewed 971 students aged 6–12 and their parents through face-to-face questionnaires. Data analysis was supported by Associate Professor Ming Wai-kit and his team from the Department of Infectious Diseases and Public Health, City University of Hong Kong. At today's event, JCI Peninsula President Irene Leung and Project Chairman Chris Ng presented the findings, joined by guest experts including Lecturer Lily Yim (City University of Hong Kong), Specialist In Developmental-Behavioural Paediatrics Dr. Sylvia Doo, Assistant Professor Dr. Rachel Chan (Department of Psychiatry, CUHK), and Dr. Lam Bing (Director, Respiratory Medicine Centre, Hong Kong Sanatorium & Hospital), who provided in-depth analysis from academic, pediatric, and clinical perspectives.
Key Findings
* Critical Sleep Deficit: 83% of surveyed students sleep fewer than 10 hours daily, far below international benchmarks.
* Excessive Academic Load: 55% of students face over 12 hours of study and homework everyday, exceeding Education Bureau guidelines.
* Blue Light Disruption: Over 70% of surveyed students use electronic devices before bedtime, suppressing melatonin secretion and delaying sleep onset.
* Lifestyle Factors: Late dinners and reliance on parental presence at bedtime contribute significantly to delayed sleep.
Expert Insights
1. Impact on Emotional Health: According to the American Academy of Sleep Medicine (AASM), children aged 6–12 should sleep 9–12 hours nightly. The survey found 51% sleep fewer than 9 hours, with 83% below the 10-hour median. Dr. Doo noted that insufficient sleep raises cortisol levels by 37%, increasing anxiety and weakening immunity.
2. Homework Overload: 55% of students spend 120 minutes daily on homework, far exceeding guidelines. Students face over 12 hours of academic pressure daily, which includes 8 hours of regular school classes and 2.1 hours of extra tutorials.
3. Blue Light Exposure: Dr. Doo explained that blue light from devices suppresses melatonin secretion by 55%, tricking the brain into perceiving daytime and reducing sleep quality.
4. Family Habits: Chairman Chris Ng highlighted that the finding revealed that students who dine after 8 p.m. were found sleeping 40 minutes less than those eating earlier. Additionally, 30% of students delayed bedtime due to waiting for parental accompaniment.
Six Recommendations for Building a Healthy Sleep Culture
1. Parents – Earlier Dinners: Encourage meals before 7 p.m. to allow the body to have sufficient time for digestion and to support deeper sleep.
2. Parents – Screen-Free Hour: Avoid electronic devices for at least one hour before bedtime to prevent children from exposure to blue light.
3. Parents – Lead by Example: Maintain healthy family routines to prevent late bedtimes.
4. Schools – Homework Guidelines: Ensure assignment quantity complies with Education Bureau standards.
5. Society – Community Education: Promote awareness of sleep hygiene as essential learning support.
6. Society – Workplace Flexibility: Advocate flexible work hours for employees with children under 12.
JCI Peninsula President Irene Leung emphasized, "Sleep is not just rest—it is the foundation of children's health and learning. In the coming months, we will organize school talks and parent-child activities to further promote the importance of sleep hygiene and raise public awareness."
