Social media is a complex network in which people design their own profile and become users. After that, enlist other users in the profile and then interact socially in a virtual world of social media and exchange information in a close network. Advancement in the technology alters the learning technique of teenagers. They reside in a world of technology as a result, get technological capability prematurely. Moreover, this capability is very significant in their academic results. It is carried out that teenagers operate these social sites for doing pleasure activities rather than for academic success. Teenagers are easily amused by social media due to its advancement.

Nowadays, Facebook, Twitter, Instagram and else is the most popular social site among teenagers. The social media addiction can happened because a lot of things. The factor of social media addiction is feel bored. Some of the factor that make someone addicted is he/she attempts to use social media networking to compensate for poorly developed interpersonal skills. Reliance on social media use as a coping mechanism for specific unwanted feelings (e.g., depression or loneliness) or as a more general tool for stress relief, and so on are also the factors. Some people belief that social media use provides vital rewards not obtainable through other means.

The social media addiction can cause a lot of damage to our body. The example of physical damage are the damage of the body posture. Numerous medical and scientific studies have shown alarming results when testing people who use smartphones for more than four hours a day and those who don’t. Smartphone users tend to develop rounded shoulders, spinal curvatures, vertebrate disorders, and associated neck pain and headaches caused by these ailments. It makes sense that using our smartphones often involves being hunched over. Our posture suffers, and we alter the muscles and bones in our torsos over time.

Second example, the damage of eyesight. Smartphones emit blue light, which is very bright for our eyes. Looking at our smartphones in bed is especially harmful, as this direct exposure to light can be damaging to our retinas, which can lead to macular degeneration (e.g, worsening eyesight).Also, a growing number of ophthalmologists are beginning to believe there’s a link between smartphone use and cataracts, with younger and younger patients experiencing cataracts instead of the typical 75-and-older crowd.

Third example is the disrupted sleep. Sleep is one of the most important factors in our overall health. In order to achieve and maintain healthy sleep, our bodies need to be able to naturally produce melatonin. Staring at smartphone screens in bed is like tricking the body into staring into a brightly-lit landscape, which delays melatonin production and prevents us from having quality sleep patterns, resulting in a host of health issues.

Social media also can affect our mental health too. The example of mental damage is

Addictive

Experts have not been in total agreement on whether internet addiction is a real thing, let alone social media addiction, but there’s some good evidence that both may exist. A review study from Nottingham Trent University looked back over earlier research on the psychological characteristics, personality and social media use. The authors conclude that “it may be plausible to speak specifically of ‘Facebook Addiction Disorder’…because addiction criteria, such as neglect of personal life, mental preoccupation, escapism, mood modifying experiences, tolerance and concealing the addictive behavior, appear to be present in some people who use [social networks] excessively.” (They also found that the motivation for people’s excessive use of social networks differs depending on certain traits—introverts and extroverts use it for different reasons, as do people with narcissistic traits. But that deserves a piece of its own.)

And studies have confirmed that people tend to undergo a kind of withdrawal: A study a few years ago from Swansea University found that people experienced the psychological symptoms of withdrawal when they stopped using (this went for all internet use, not just social media). Their recent follow-up study found that when people stop using, they also undergo small but measurable physiological effects. Study author Phil Reed said, “We have known for some time that people who are over-dependent on digital devices report feelings of anxiety when they are stopped from using them, but now we can see that these psychological effects are accompanied by actual physiological changes.” Whether this is true of social media per se is unclear right now, but anecdotal evidence suggests it may be.

Teenagers get more sadness, less well-being

The more we use social media, the less happy we seem to be. One study a few years ago found that Facebook use was linked to both less moment-to-moment happiness and less life satisfaction—the more people used Facebook in a day, the more these two variables dropped off. The authors suggest this may have to do with the fact that Facebook conjures up a perception of social isolation, in a way that other solitary activities don’t. “On the surface,” the authors write, “Facebook provides an invaluable resource for fulfilling such needs by allowing people to instantly connect. Rather than enhancing well-being, as frequent interactions with supportive 'offline' social networks powerfully do, the current findings demonstrate that interacting with Facebook may predict the opposite result for young adults—it may undermine it.”

In fact, another study found that social media use is linked to greater feelings of social isolation. The team looked at how much people used 11 social media sites, including Facebook, Twitter, Google+, YouTube, LinkedIn, Instagram, Pinterest, Tumblr, Vine, Snapchat and Reddit, and correlated this with their “perceived social isolation.” Not surprisingly, it turned out that the more time people spent on these sites, the more socially isolated they perceived themselves to be. And perceived social isolation is one of the worst things for us, mentally and physically.

Teenagers comparing their lives with others,Its is mentally unhealthy

Part of the reason Facebook makes people feel socially isolated (even though they may not actually be) is the comparison factor. We fall into the trap of comparing ourselves to others as we scroll through our feeds, and make judgements about how we measure up. One study looked at how we make comparisons to others posts, in “upward” or “downward” directions—that is, feeling that we’re either better or worse off than our friends. It turned out that both types of comparisons made people feel worse, which is surprising, since in real life, only upward comparisons (feeling another person has it better than you) makes people feel bad. But in the social network world, it seems that any kind of comparison is linked to depressive symptoms.

It can lead to jealousy—and a vicious cycle

It’s no secret that the comparison factor in social media leads to jealousy—most people will admit that seeing other people’s tropical vacations and perfectly behaved kids is envy-inducing. Studies have certainly shown that social media use triggers feelings of jealousy. The authors of one study, looking at jealousy and other negative feelings while using Facebook, wrote that “This magnitude of envy incidents taking place on FB alone is surprised, providing evidence that FB offers a breeding ground for invidious feelings." They add that it can become a vicious cycle: feeling jealous can make a person want to make his or her own life look better, and post jealousy-inducing posts of their own, in an endless circle of one-upping and feeling jealous.

Another study looked at the connection between envy and depression in Facebook use and, interestingly, discovered that envy mediates the Facebook-depression link. That is, when envy is controlled for, Facebook isn’t so depressing. So it may be the envy that’s largely to blame in the depression-Facebook connection.

We must avoid the social media addiction. There are a few step I want to share. First, turn off the notification of your phone. When you stop notifications from disturbing your normal routine, you might find it easier to concentrate on your daily tasks and not get distracted so easily. Notifications are a constant reminder that something is happening in the online world and you might feel like you're missing out. The bonus is, when you do come around to checking your social media, you may have a build-up of more notifications which will make it more exciting and will make the experience more rewarding. Second, we can limit the time we use the social media. Set a timer on your watch or phone, to limit the amount of time you spend on social media. When you reach the limit, be strong and don't be tempted to add on extra time. This will be a strong test of your willpower, but it will be worth it in the end. And the last you can find your new hobby such as playing guitar, violin and many more. You could learn a new skill or do something you've always wanted to do but never had the time. You'll probably surprise yourself at how much free time you have when you stop mindlessly scrolling through your newsfeed. Plus your new hobby will keep your mind and hands preoccupied when you're craving social media.
