Brain Awareness Week: Screen Time and Its Impact on Children’s Brain

Table of Contents

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 undoubtedly affects sleep and attention. When an individual is exposed to artificial light emitted by digital screens, circadian rhythms can be disrupted, affecting sleep patterns. Higher-order cognitive processes, such as attention and alertness, are important for effective professional and academic performance. However, they have displayed sensitivity to acute and chronic 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:  Add zero-screen time to your daily routine so that you can have time to relax. This can reduce cognitive fatigue and restore attention. 
• Physical Activities: Spending time on things off the screen provides neural stimulation that is unavailable in the digital world. Activities support emotional balance and long-term brain health. 
• Building Connections: The social media impact is such that we have forgotten the importance of forming physical social interactions. These physical social connections engage cognitive faculties in ways digital communication cannot. 
• Mindfulness: It is best to disable notifications that are not important and to use apps when they are needed. This reduces compulsion and limits scrolling. 

If you are facing attention-related or emotional issues despite taking measures, it may be best to consult a psychiatric doctor. They can offer personalised tips. 

When to Seek Professional Help

It is best to seek professional help if screen time causes persistent sleep issues or leads to social withdrawal. If a child is constantly irritable or academically weak, it may be beneficial to visit a mental health hospital. Any other behavioural, social, emotional, or physical issues that are not resolved need to be monitored by a professional. 

FAQs

Q. What is Brain Awareness Week and its purpose?

A.It is a global campaign held in March to promote neuroscience and raise awareness of research progress. It is co-ordinated by the Dana Foundation and includes events, workshops and lectures. 

Q. How does screen time affect children’s brain development?

A. Too much screen time can affect cognitive abilities in the early years and academic performance later. When a lot of time is spent on screen, interactions with caregivers and peers are reduced, which may also affect language development. 

Q. What are the effects of excessive screen use on children?

A. Children who use screens often may face physical issues like obesity, eye strain and poor sleep. Issues such as anxiety, aggression and depression are also common. Screen use can also affect social skill development. 

Q. How much screen time is healthy for children?

A. Some studies have indicated that children who view screens for more than an hour per day are more likely to develop behavioural issues than those who use screens for less than an hour per day. It is best to keep screen time under an hour and introduce digital detoxes. 

Q. How can parents protect children’s brain health?

A. Parents can protect a child’s brain health by setting clear boundaries, such as no screens during meals and promoting physical activity. They can use parental controls and model healthy behaviour.
