The article examines a study that explored university students' dependence on screens and online games during the COVID-19 pandemic. The study identified four distinct groups: 'non-addict and non-gamer', 'gamer but not an addict', 'addict but not a gamer', and 'highly dependent and gamer'. These groups reflect a variety of behaviors and levels of dependence among students.

It is essential to consider the impact of screens on children’s sleep and to implement measures to reduce these harmful effects. By taking a proactive approach and creating an environment conducive to sleep, parents can play an important role in improving their children’s quality of life and in promoting their healthy development.

Nowadays, screens have become omnipresent in children's daily lives. Whether at home, at school, or even in public places, children are constantly exposed to these electronic devices. However, this dependence on screens can have harmful consequences for their development, particularly with regard to their learning abilities. Learning disorders are specific difficulties that affect a child's ability to acquire certain academic skills, such as reading, writing, mathematics, or concentration. These disorders can be caused by various factors, such as genetic problems, brain injuries, developmental disorders, or environmental factors such as excessive exposure to screens. One of the main reasons why screens can cause learning disorders in children is the excessive time spent in front of these devices. When a child spends hours playing video games, watching videos, or surfing the Internet, they significantly limit the time they could devote to more cognitively enriching activities, such as reading, writing, or math exercises. This reduction in learning time can lead to a delay in the development of essential academic skills. Moreover, screens can also have a negative impact on children's concentration and attention. Constant visual and auditory stimuli from screens can disrupt their ability to focus on a given task, which can make them more easily distracted and less able to concentrate in class. This difficulty concentrating can lead to lower academic performance and a sense of frustration in children. Another consequence of excessive screen exposure is its impact on children's sleep. The blue light emitted by screens can disrupt the circadian rhythm and suppress the production of melatonin, a hormone essential for regulating sleep. When children spend time in front of screens before going to bed, this can cause sleep problems such as insomnia or difficulty falling asleep. Poor-quality sleep can have a significant impact on children's cognitive abilities and learning. It is therefore essential to limit children's exposure to screens and to promote activities that are more beneficial for their development. Parents and educators can encourage children to read books, play board games, and engage in sports or artistic activities, which will stimulate their creativity, imagination, and cognitive skills. It is also important to set clear limits regarding screen time and to establish strict rules, such as no screens before bedtime or no screens during meals. In conclusion, screens can have harmful consequences for children's learning abilities. Excessive exposure can lead to learning disorders, concentration problems, and sleep disturbances. It is therefore crucial to limit time spent in front of screens and to encourage activities that are more stimulating for their development. By encouraging children to engage in activities that strengthen their academic skills and foster their creativity, parents and educators can contribute to their well-being and academic success.

This article highlights the negative consequences of excessive screen use on children's social and emotional capacities. Social isolation, attention problems, and emotional difficulties are the main observed effects. Prolonged screen use limits face-to-face interactions, which are essential for the development of social skills. Additionally, it can lead to attention problems and a decline in emotional skills. To minimize these consequences, it is recommended to set clear limits on screen time, promote a balance between digital and non-digital activities, and encourage face-to-face interactions, outdoor activities, reading, and creative play. The 3-6-9-12 rule is a useful guide for children's screen use, gradually limiting screen time according to age.

This article explains that excessive screen use can have harmful effects on the development of children's self-esteem. Digital media can promote unrealistic beauty standards, which can lead children to compare themselves to others and feel dissatisfied with their appearance. Additionally, screens can foster addiction and socially isolate children, which can also affect their self-esteem. Excessive screen time can also keep children from tackling real-life challenges, which are important for building their confidence. It is therefore recommended to limit time spent in front of screens and to promote balanced activities such as face-to-face social interactions, physical activities, and creative pastimes to foster healthy self-esteem development in children.
