They also mention that their pre-sleep habits or when they have trouble falling asleep include using their phones, even placing their phones on the bed while they sleep. They reveal that sometimes they stay online until late at night, whether it’s playing games, watching movies, or engaging in social media activities, which leads to difficulty sleeping and restless sleep, resulting in feeling unrefreshed and even dizzy upon waking up in the morning. The objective of this community service initiative is to assist students in enhancing their knowledge and strategies to improve sleep hygiene, thereby preventing sleep disorders among adolescents.
