UK researchers used a dataset of more than 800 million Twitter messages to evaluate how collective mood changes over the course of 24 hours and across the seasons. The research team collected 800 million anonymous Tweets from 33,576 time points over four years, to examine anger and sadness and compare them with fatigue. The "research revealed strong circadian patterns for both positive and negative moods. The profiles of anger and fatigue were found remarkably stable across the seasons or between the weekdays/weekend." The "positive emotions and sadness showed more variability in response to these changing conditions and higher levels of interaction with the onset of sunlight exposure." 
Social medias are the key window to get the information from every corner of the globe. Social media facilitate the development of social networks by connecting a users profile with the other individuals or the groups. It is the great platform of communications. Different social medias such as: google, facebook, instagram, whatsapp, twitter and so on which are providing a range of a positive and negative impacts on our daily life.
They certainly overlap, which is why it gets confusing. For example, you can share media with your social network to gather likes and comments — a form of social networking. But you can also just upvote a link on Reddit, which is a social media platform, to help out the community and give your say in the matter without any intention of building relationships with other users.
Social media content is generated through social media interactions done by the users through the site. There has always been a huge debate on the ownership of the content on social media platforms because it is generated by the users and hosted by the company. Added to this is the danger to security of information, which can be leaked to third parties with economic interests in the platform, or parasites who comb the data for their own databases. The author of Social Media Is Bullshit, Brandon Mendelson, claims that the "true" owners of content created on social media sites only benefits the large corporations who own those sites and rarely the users that created them.
Isabelle agrees. “Constant screen time damages your ability to see, and it also causes internal damage, such as anxiety.” Studies have shown that social media use can negatively affect mental wellbeing, and adolescents are particularly susceptible: one nationally representative survey of US 13- to 18-year-olds linked heavier social media use to depression and suicide, particularly in girls. And 41% of the Gen Z teens surveyed by Hill Holliday reported that social media made them feel anxious, sad or depressed.
Social media is not something you can simply "tack on" to the rest of your marketing, branding, PR, and advertising efforts; it needs to be a fully integrated part of the mix. In doing so, you can create a cohesive and scalable experience for your customers. Think of it as a means to an end, and not an end in itself. Also, it's not as hard as it sounds.
According to writer Christine Rosen in "Virtual Friendship, and the New Narcissism," many social media sites encourage status-seeking. According to Rosen, the practice and definition of "friendship" changes in virtuality. Friendship "in these virtual spaces is thoroughly different from real-world friendship. In its traditional sense, friendship is a relationship which, broadly speaking, involves the sharing of mutual interests, reciprocity, trust, and the revelation of intimate details over time and within specific social (and cultural) contexts. Because friendship depends on mutual revelations that are concealed from the rest of the world, it can only flourish within the boundaries of privacy; the idea of public friendship is an oxymoron." Rosen also cites Brigham Young University researchers who "recently surveyed 184 users of social networking sites and found that heavy users 'feel less socially involved with the community around them.'" Critic Nicholas G. Carr in "Is Google Making Us Stupid?" questions how technology affects cognition and memory. "The kind of deep reading that a sequence of printed pages promotes is valuable not just for the knowledge we acquire from the author's words but for the intellectual vibrations those words set off within our own minds. In the quiet spaces opened up by the sustained, undistracted reading of a book, or by any other act of contemplation, for that matter, we make our own associations, draw our own inferences and analogies, foster our own ideas... If we lose those quiet spaces, or fill them up with "content," we will sacrifice something important not only in ourselves but in our culture."
After being “bugged” by his friends to get Instagram (he had stopped using Facebook aged 16), Johnson joined. He lasted six months. “If you’re having a bad day and scrolling through it, you’re constantly bombarded with pictures of people going to parties. Even if that’s not an accurate portrayal of their lives, that’s what you see. So I stopped using it. It became depressing. It was this competition of who’s the happiest.” He pauses. “Participating in that is not something I’m interested in.”

Social Media is the next big marketing giant, be it Twitter for Business, a product review at Periscope (though not everyone knows about it) or a successful ad campaign on the Facebook with a tremendous reach to the potential clients. Of all, Facebook is my best bet as it has directly favored my test tube business with a mere $500 ad campaign with $5000 increase in profits.
On social media, consumers are exposed to purchasing practices though peer sent, written messages. Learning through social media includes strategies such as "modeling, reinforcement, and social interaction mechanisms" all at the same time. A study, that focused on peer communication through social media, has revealed that communication between peers through social media is positively related to purchase intentions in a couple ways. First, is a direct impact through conformity. Second, is an indirect impact by stressing product engagement. Lastly, from this study, we learned that consumer-related communication between peers on social media has a positive relationship with product engagement. 
Networks formed through social media change the way groups of people interact and communicate. They "introduce substantial and pervasive changes to communication between organizations, communities, and individuals." These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as TV broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and performance. Social media outlets operate in a dialogic transmission system (many sources to many receivers). This is in contrast to traditional media which operates under a monologic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites are Facebook (and its associated Facebook Messenger), Instagram, WhatsApp, Google+, Myspace, LinkedIn, Pinterest, Snapchat, Tumblr, Twitter, Viber, VK, WeChat, Weibo, Baidu Tieba, and Wikia. These social media websites have more than 100,000,000 registered users.
