Web Desk: Children who spend more time using screens tend to show poorer outcomes in several areas of development, including learning, language, behavior and emotional regulation, according to a major review of research spanning several decades.
The analysis examined studies involving nearly 3 million children aged 18 and under across 64 countries. Researchers found an overall association between greater screen exposure and less favorable outcomes in how children think, learn, communicate, behave and manage their emotions.
The associations were generally small, but researchers said they remain meaningful given how widespread screen use has become in children’s everyday lives.
The review also found indications that more recent studies have reported stronger links between screen exposure and child development than older research.
One possible explanation is the significant transformation in how children use digital devices.
Children two decades ago were more likely to spend a limited period watching television. Today, smartphones, tablets and other connected devices are portable, interactive and designed to respond to individual users.
As a result, children’s exposure to technology is no longer limited to particular periods of the day. Digital devices can accompany them across different settings and activities, potentially changing how screen use competes with other aspects of childhood.
The findings highlight the need to examine not only how children interact with technology but also how digital technology responds to and potentially influences children’s behavior.
The study does not suggest that parents should consider all screen use harmful or attempt to eliminate digital devices completely.
Technology can support children’s education, creativity and social connections when used appropriately. However, excessive screen use can take time away from activities that are important for healthy development.
Those activities include sleep, physical exercise, face-to-face interaction, learning and play.
Rather than banning devices, families can identify situations in which screen use interferes with these essential activities. Device-free family meals or setting aside a regular period each day without screens can provide practical ways to create more opportunities for interaction.
Managing children’s digital habits should not be viewed solely as a responsibility for parents.
Public authorities can support families through screen-use guidance, education and research while strengthening measures to protect children from harmful online experiences.
Such policies can also encourage schools and technology companies to recognise children’s digital well-being as an important consideration.
The review identifies a relationship between screen exposure and developmental outcomes but does not establish that screen use directly causes developmental difficulties.
The relationship could potentially operate in both directions. While greater screen exposure may contribute to certain difficulties, children who are already struggling could also be more likely to spend time using digital devices.
Determining the direction of these relationships will require further research.
Future studies will also examine why some children may be more affected by particular digital experiences than others and whether different types of technology use produce different outcomes.
The research adds to growing evidence about the relationship between children’s digital lives and their development.
While greater screen exposure was associated with poorer developmental outcomes, the findings suggest that the broader context of technology use also matters.
The type of activity, purpose of use and whether screen time replaces sleep, exercise, social interaction, learning or play may all influence children’s experiences.
Further research is expected to examine these factors more closely and identify which digital experiences may carry greater developmental risks and which can provide meaningful benefits.
