The average child under the age of 13 in today's world can't go an hour without looking at a device with the Internet on it, and that makes me wonder if the Internet is actually strengthening children's mental health.
 
I am going to talk about three main concepts that show whether the Internet actually strengthens children's mental and physical health. Does the Internet benefit children's growth? Does the average student benefit from social media? And will the internet increase childhood obesity in 2024? 

My opinion on whether the Internet strengthens mental and physical health is no. Because, you see, the Internet can be and is a very useful tool for education, work, and social interaction. But too much of anything, especially the Internet, can lead to depression, social anxiety, and fatigue. 

While it can be a very useful tool for education, work, social interaction, and entertainment, overuse can take a toll on your health, according to Dr. Saju Mathew, a Piedmont family physician. The Internet, when used too much, can drastically affect the average child's mental health. A study at the University of Pennsylvania in the U.S. found a high use of Facebook, Snapchat, Instagram, and other social media increases rather than decreases feelings of loneliness.Just imagine an adolescent child reading rude comments about themselves from their classmates; it would be very unhealthy for that child's mental health.

Now let's go over my first main concept. Does the Internet benefit the physical health of children in this modern age, even though this generation has better health care, technology, and food? Back in the 1980s, people were not too reliant on their devices to entertain them; they would go outside to entertain themselves. And I think that is what kids in today's world are lacking in terms of sunlight and physical preparation. If kids in 2024 are spending more time typing, tapping, or looking at a screen, they're going to spend less time outside or doing physical activity. 

That concludes Principle One, and now we move on to Principle Two. Does the average child's mental health benefit from the Internet?
No, in my experience of observing my peers, I have noticed that many of them are almost glued to the Internet. And they see some very disturbing things—even things that will definitely affect your mental morale. Also, my peers are on their devices for more than 7 hours a day! That cannot be healthy for a human being.
 
According to the findings of CFPS 2018, excessive internet use leads to increased levels of depression and decreased cognitive function.To further support my argument, a study from the University of Pennsylvania in the U.S. found that high use of Facebook, Snapchat, Instagram, and other social media increased feelings of loneliness rather than decreased them.

After that we have Principle 3, which would be: Has the Internet increased childhood obesity? Yes, it has. Compared to the 1970s, the Internet has made obesity very common. Some kids with access to the Internet are lazy, bored, and think it's okay to stay on their gadgets for more than 3 hours a day! But that kind of attitude is exactly why childhood obesity is on the rise.
In 2016, the World Health Organization reported that nearly 170 million children under the age of 18 were overweight or obese [1].
Some researchers consider this concern for children to be one of the greatest and most significant threats to child health in the last twenty years [2, 3]. Obesity is now recognized as a serious threat to society due to its rapidly increasing prevalence [4]. Consequently, the focus in the coming years should be on the prevention of childhood overweight and obesity.

Lastly we have principle 4. Which is, Does social media help kids deal with Fear of missing out and loneliness?
According to Melina Smith, M.A, While Fear of Missing out has been around way longer than social media, social media such as. such as Facebook,Instagram, and snapchat. seem to induce feelings that others are having more fun or living better lives than you are. The idea that you’re missing out on certain things can impact your self-esteem, trigger anxiety, and make you feel very depressed that other people are not, much like an addiction. FOMO can make you pick up your phone every few minutes to check for updates, or compulsively respond to each and every piece of news or information you. Loneliness has also increased because of social media. Some of my peers and other childhood friends that use social media have been experiencing depression and loneliness on social media because of repeated teasing, bullying, and showing off to others.

To summarize my main concepts, the Internet is not beneficial to the physical health of children under the age of 13. Because the Internet is so addictive for some children, childhood obesity is on the rise. And social media boosted loneliness and the fear of missing out. 
I believe that the Internet has strengthened some aspects of children's mental health, including communication, entertainment, and social interaction. But it has a lot of negative effects when used too much, like depression, obesity, and social anxiety. If you want to take action, I recommend reducing your screen time to less than 2 hours a day to reduce mental depression and improve physical health.
