Social Networking Service (SNS) is a system that enables people to form a broad human network by strengthening human relationships with acquaintances, such as friends and colleagues, on the Internet, or by forming
new personal networks. These SNS platforms have brought about various changes in our lives, both positive and negative.

The advantages of SNS platforms are that it is used as an open forum for prompt information delivery, easy social networking, formation of bonds through sharing of private life, and voices about social phenomena. Freely communicating with family and friends far away through SNS media such as KakaoTalk and Facebook has become a part of our daily lives, and many deem this as the reason behind the successes of such platforms.

On the other hand increasing reliance on SNS platforms has caused issues of privacy protection and excessive invasion of the realm of daily life. Not only this, but the excessive use of SNS can adversely affect mental health, leading to immersion, dependence, and addiction, and causing digital fatigue and anxiety. In recent years, studies on SNS addiction and smartphone addiction have been a central part of the psychology scholastic community. Addiction to SNS can cause various serious symptoms, which are very similar to the phenomena found in previously studied internet addiction. In other words, when addicted to SNS, symptoms such as life disorder, inability to stop attempts, time tolerance, and withdrawal anxiety appear, and these SNS addictions are linked to various psychological problems such as anxiety, depression, loneliness, and self-exaggeration.

It is quite obvious to see how SNS can be a double-edged sword. Although SNS has brought about convenience and new forms of communication, it has also led to a reduction in direct social interaction. Many people spend their time on their phones rather than engaging in face-to-face conversations. In this way, SNS has altered our lifestyle. So, how can we fully utilize the advantages of SNS while reducing the disadvantages and harms? First, we need to establish a balance between online and offline exchanges. In addition, developing self-regulation ability is essential to prevent SNS addiction from progressing. Establishing a clear set of values for your life and finding productive, positive addictions
(activities and topics that you can engage with and give you inner satisfaction) is one way to do it.

While science and technology will continue to develop to become essential to our lives, it is important to make efforts to create a more balanced and fulfilling life, both online and offline.
