Affinity Health, a leading provider of high-quality health cover, highlights the importance of understanding and addressing childhood obesity.
“In today’s digital world, screens are a big part of children’s daily lives, from online learning to gaming and social media. But relying on technology so much can have downsides,” says Murray Hewlett, CEO of Affinity Health.
“According to The Conversation, teens spend about 8.5 hours a day on screens, while tweens (ages 8 to 12) are close behind, averaging 5.5 hours daily.”
While digital devices offer opportunities for learning and connectivity, their overuse poses significant risks to children’s mental and physical well-being.
Reduced physical activity, poor sleep patterns, and heightened exposure to unhealthy eating cues are just a few of the ways excessive screen time exacerbates obesity concerns.
Screen Time and Mental Health
Excessive screen time has also been linked to several mental health challenges in children, including:
- Increased Anxiety and Depression
Too much screen time, especially on social media, exposes kids to cyberbullying, unrealistic comparisons, and FOMO (fear of missing out). This can increase anxiety, lower self-esteem, and even lead to depression.
- Sleep Disturbances
Screens emit blue light that blocks melatonin, the hormone needed for sleep. Kids using devices before bed can disrupt their sleep, causing fatigue, irritability, and lower school performance.
- Reduced Attention Span
Overexposure to fast-paced digital content can impair children’s ability to concentrate on tasks requiring sustained focus, affecting their academic and social development.
- Social Isolation
Excessive screen use can replace in-person interactions, reducing children’s opportunities to develop essential social skills and healthy relationships.
Screen Time and Obesity
Childhood obesity is a global health crisis, with rates nearly tripling over the past four decades. Screen time plays a direct and indirect role in this epidemic:
- Sedentary Lifestyle
Long hours spent on screens reduce children’s time in physical activities like playing outdoors, cycling, or sports. A sedentary lifestyle significantly contributes to weight gain and associated health issues.
- Mindless Eating and Overeating
Snacking is often accompanied by screen time, particularly on unhealthy, high-calorie foods. Watching TV or playing video games while eating can distract children from recognising their body’s hunger and fullness signals, leading to overeating.
- Exposure to Junk Food Advertising
Advertisements for sugary snacks, fast food, and drinks easily influence children. Screen-based marketing often targets young viewers and promotes unhealthy eating habits.
- Disrupted Metabolism
Prolonged sitting slows down metabolic processes, contributing to weight gain and increasing the risk of developing chronic diseases such as Type 2 diabetes and hypertension.
Striking a Healthy Balance
While eliminating screen time is neither realistic nor necessary, managing it can significantly improve a child’s mental and physical health. Here are some practical tips:
Set Screen Time Limits: The World Health Organization (WHO) recommends that children aged 2–5 years have no more than one hour of screen time per day, and children aged 6 years and older should have consistent limits to ensure screen time doesn’t interfere with physical activity, sleep, and other essential behaviours.
Encourage Physical Activity: Encourage your child to spend at least 60 minutes daily on physical activities like sports, walking, or dancing. Family activities such as hiking or cycling can be a fun way to bond while promoting fitness.
Create Tech-Free Zones: Designate specific areas in your home, such as the dining room or bedrooms, as screen-free zones. This can help reduce mindless snacking and promote better sleep hygiene.
Monitor Content: Supervise the type of content your child consumes to ensure it’s age-appropriate and positive. Educational apps and programs can be a better alternative to purely entertaining ones.
Foster Healthy Eating Habits: Encourage mindful eating by serving meals and snacks away from screens. Involve children in meal preparation to teach them about nutrition and the importance of balanced diets.
Lead by Example: Children often mirror their parents’ habits. By managing your screen time and prioritising physical activities, you can set a positive example for your child.
Long-Term Health Consequences
Unchecked screen time and its link to obesity can lead to severe long-term health consequences, including:
Obesity in childhood increases the risk of developing Type 2 diabetes, cardiovascular diseases, and joint problems later in life.
- Mental Health Challenges
Poor mental health stemming from excessive screen use can persist into adulthood, affecting relationships, career, and overall well-being.
- Lower Quality of Life
Children who struggle with obesity and mental health issues may face social stigma, reduced self-esteem, and limited opportunities for an active lifestyle.
