Self-esteem can be defined as the attitude and confidence a person has towards its own self to achieve a goal; self-respect. Studies show that children who exhibit self-esteem issues spend an excessive time on social media and this restricts them from exploring the real world. Spending excessive time on social media impacts how a person perceives him/herself. People create idealised online personas.
Advertising have long been criticised for portraying unrealistic and impossible standards of success and beauty. Nowadays, these unrealistic standards are not depicted through models or celebrities but through friends and classmates. Social media is designed to showcase the highlights in people’s lives. It created the possibility of a person to curate their life and post desirable and amazing moments, to elicit envy from others. Self-esteem is also influenced by comparing the number of likes or followers a person has compared to others.
People have the possibility to conceal their real life struggles of day to day life. There is evidence that these images are causing distress for younger people, because they start doubting their own life and compare it to other’s lives, according to what they see online.
For people who are experiencing anxiety or depression, they mask their struggles through carefully editing their feeds. This makes it harder for parents or friends to realise that they need help.
“It’s important to remember that just posting edited pictures online or pretending your life is a little more glamorous than it is is not in itself a problem,” says Jill Emanuele, PhD, a clinical psychologist at the Child Mind Institute. “Social media alone is unlikely to be at the heart of the issue, but it can make a difficult situation even harder.”

According to a study, girls were more likely to have low self-esteem (12.8 percent vs. 8.9 percent for boys), to have body weight dissatisfaction (78.2 percent vs. 68.3 percent) and to be unhappy with their appearance (15.4 percent vs. 11.8 percent) (DeseretNews, 2019)
There is a gap between who people truly are in real life and who they pretend to be online. This gap may lead to frustration and depression. If you feel as though your self-esteem is impacted after scrolling through social media, limit your social media consumption and avoid making comparisons. Remember social media is only a highlight reel, it does not give the bigger picture and everything is edited.
