Using Twitter to monitor the attitudes and emotions of 2.4 million people in 84 countries for two years, scientists at Cornell University (USA) have found that people usually wake up in a good mood but that, in general, her mood declines as the day progresses. As revealed by Scott A. Golder and Michael Macy in an article published today in the journal Science , negative emotions (anguish, fear, guilt, anger or disgust) increase throughout the day, while positive emotions (enthusiasm, liveliness and pleasure ) descend in the central part of the day and recover again at night. In other words, emotions follow a cyclical rhythm. And, according to the authors, work, sleep and the amount of natural light to which we expose ourselves influence that rhythm.
On the other hand, the analysis shows that tweets with content that reveal a positive attitude are more frequent very early in the morning and close to midnight. There are also more positive messages on the microblogging network on Saturdays and Sundays , except in the United Arab Emirates, where the mood improves on Friday mornings, which are non-working days.
