Brain Awareness Week: Screen Time and Its Impact on Children’s Brain
Synopsis
Brain Awareness Week is a global campaign organised by Dana Foundation. It highlights the developments in brain research and promotes brain health. It also helps shed light on children’s brain development, specifically the impact of excessive screen time on their behaviour, sleep and cognitive development. Developing healthy screen habits can help individuals make choices that support brain health and overall wellbeing.

Introduction
Brain Awareness Week is an international campaign that aims to inform people about the progress being made in brain research. It is organised by the Dana Foundation and emphasises the impact of brain science on everyday life. During this week, activities may be organised to promote and communicate about brain health.
When Is Brain Awareness Week Observed?
Every year, this campaign is organised in mid-March. The dates for Brain Awareness Week 2026 are 16-22 March. The events, held every year, include lectures, lab tours, brain fairs, and student lessons. These outreach activities are supported by grant programs.
Participating in Brain Awareness Week activities can help understand the role of brain science and may promote productive and healthy lives. The campaign, through knowledge exposure, helps individuals make better decisions about their health.
How the Brain Develops in Children
Here is how brain connections are built:
- At birth, an average child’s brain is small but doubles in size in the first year.
- A baby’s brain can form over a million new neural connections per second.
- These connections enable all capabilities from movement to problem-solving.
- These connections form through interactions with caregivers and daily activities.
As relationships with adults play an important role in a child’s brain development, caregivers must know more about brain development. Campaigns like Brain Awareness Week can help attain such valuable information.
Screen Time and Brain Development
While devices can improve learning, they can also disrupt sleep, creativity and everything in between. During early childhood, when the human brain is constantly forming neural connections, screens fail to provide high-quality stimulation.
Digital media operates on a variable-reward system, which may create obsessive behaviour. Such behaviour may be difficult to stop, as a young individual’s self-control system may not be fully developed.
Impact of Excessive Screen Use on Children
The following are some ways in which excess screen usage can have negative effects on children:
- Excess screen time provides poor stimulation for a developing brain.
- A screen’s blue light can disrupt sleep by suppressing melatonin secretion.
- It can affect caregiver-child interactions and language development.
- Device use may affect emotional interpretation and increase aggression.
The negative effects of too much screen usage can be reduced and healthy development promoted by increasing knowledge and encouraging activity.
Effects of Screen Exposure on Sleep and Attention
Excessive screen time affects sleep and attention. Exposure to artificial light disrupts circadian rhythms, impacting sleep patterns. Cognitive processes like attention and alertness are sensitive to sleep disruption.
Behavioural and Emotional Changes Linked to Screen Use
Excessive screen time can induce stress reactions and increase irritability. It can overload the sensory system, reduce attention and lead to emotional meltdowns.
Frequent screen use can affect social and emotional growth and may be linked to anxiety and depression symptoms.
Healthy Screen Time Guidelines for Children
These recommendations can help make healthier choices:
- Limit screen use for children under 18 months to video calls only.
- Avoid using screens to manage behaviour.
- Remove screens before bedtime.
- Limit use during meals and outings.
- Encourage non-screen activities.
- Limit non-educational screen time.
- Increase outdoor activities.
Ensure quality screen time by previewing content and using parental controls.
Tips to Support Brain Health in the Digital Age
- Detox: Include daily zero-screen time.
- Physical Activities: Encourage offline activities.
- Building Connections: Promote real-life interactions.
- Mindfulness: Limit unnecessary notifications.
If issues persist, consult a professional.
When to Seek Professional Help
Seek help if screen time causes sleep issues, irritability, or affects academic and social functioning.
