In a learning environment, a common cause of boredom is lack of understanding; for instance, if one is not following or connecting to the material in a class or lecture, it will usually seem boring. However, the opposite can also be true; something that is too easily understood, simple or transparent, can also be boring. Boredom is often inversely related to learning, and in school it may be a sign that a student is not challenged enough, or too challenged. An activity that is predictable to the students is likely to bore them.[31]
“Time is quixotic because it can torment us. When we have insufficient stimulus to fill our lives, we resent the relentless quality of time, and we engage in activities designed to “kill time.” Time that passes slowly creates insufferable boredom; time that passes to quickly makes us aware of our accelerated death march. A person’s perspective on time depends mostly on what they are most afraid of, boredom or death.”

Only in the last decade has there been much scientific research looking into the nature of boredom. In 2006, a study classified boredom into four different types, with a follow-up study published this month in the journal Motivation and Emotion adding a fifth kind of boredom, called apathetic boredom, to the list. The researchers involved in the study had 63 university students and 80 high school students answer smartphone-based surveys about their activities and experiences over the course of two weeks.

The superfluous man (Russian: лишний человек, lishniy chelovek) is an 1840s and 1850s Russian literary concept derived from the Byronic hero.[42] It refers to an individual, perhaps talented and capable, who does not fit into social norms. In most cases, this person is born into wealth and privilege. Typical characteristics are disregard for social values, cynicism, and existential boredom; typical behaviors are gambling, drinking, smoking, sexual intrigues, and duels. He is often unempathetic and carelessly distresses others with his actions.
“Boredom is a flight from what is important. Like workaholism and perfectionism, it is a way of distracting yourself from inner experiences. It occurs when you look outward and do not find anything to engage your attention. Instead of feeling your emotions - becoming aware of the functioning of your energy system - you become bored. Boredom ... is a flight from your higher potential. It is fear of the transformation that wants to occur, and will occur in you, when you explore your emotions. It is your resistance to spiritual growth.”
Thomas Goetz, the lead researcher of the work and a professor at the University of Konstanz in Germany, says the multiple types of boredom can be loosely characterized along two dimensions. First, whether it is associated with a positive (score of 1) or negative (score of 5) emotion, and second, by degree of arousal, from calm (score of 1) to fidgety (score of 5).

Lethargy is a state of tiredness, weariness, fatigue, or lack of energy. It can be accompanied by depression, decreased motivation, or apathy. Lethargy can be a normal response to boredom, inadequate sleep, overexertion, overworking, stress, lack of exercise, or a symptom of a disorder. When part of a normal response, lethargy often resolves with rest, adequate sleep, decreased stress, and good nutrition.[21][22]
The authors of this paper point to an interesting study by Robin Damrad-Frye and James Laird in the August 1989 issue of the Journal of Personality and Social Psychology. In this study, participants had to listen to a tape of a person reading a Psychology Today article. In the next room, there was a television soundtrack from a soap opera playing. For some groups listening to the article, the TV was very loud and distracting, for others it was barely noticeable, and for some it was not playing at all. After listening to the article, people rated their boredom during the study. 
In contexts where one is confined, spatially or otherwise, boredom may be met with various religious activities, not because religion would want to associate itself with tedium, but rather, partly because boredom may be taken as the essential human condition, to which God, wisdom, or morality are the ultimate answers. Many existentialist philosophers, like Arthur Schopenhauer, espouse this view. This view of religiosity among boredom does affect how often people are bored. People who had a higher religiosity while performing boring task, reported less boredom than people of less religiosity. People performing the meaningless task had to search less for meaning.[24]
Boredom also plays a role in existentialist thought. Søren Kierkegaard and Friedrich Nietzsche were two of the first philosophers considered fundamental to the existentialist movement. Like Pascal, they were interested in people's quiet struggle with the apparent meaninglessness of life and the use of diversion to escape from boredom. Kierkegaard's Either/Or describes the rotation method, a method used by higher level aesthetes in order to avoid boredom. The method is an essential hedonistic aspect of the aesthetic way of life. For the aesthete, one constantly changes what one is doing in order to maximize the enjoyment and pleasure derived from each activity.
Then, after a baseline EEG test measuring normal brain activity, the researchers assigned the participants a tedious task: they had to turn eight virtual pegs on a screen as the computer highlighted them. This activity lasted approximately 10 minutes, during which time the researchers used EEG caps to measure participants’ brain activity as they carried out the boring task.
Boreout is a management theory that posits that lack of work, boredom, and consequent lack of satisfaction are a common malaise affecting individuals working in modern organizations, especially in office-based white collar jobs. This theory was first expounded in 2007 in Diagnose Boreout, a book by Peter Werder and Philippe Rothlin, two Swiss business consultants. They claim the absence of meaningful tasks, rather than the presence of stress, is many workers' chief problem.
Although it has not been widely studied, research on boredom suggests that boredom is a major factor impacting diverse areas of a person's life. People ranked low on a boredom-proneness scale were found to have better performance in a wide variety of aspects of their lives, including career, education, and autonomy.[30] Boredom can be a symptom of clinical depression. Boredom can be a form of learned helplessness, a phenomenon closely related to depression. Some philosophies of parenting propose that if children are raised in an environment devoid of stimuli, and are not allowed or encouraged to interact with their environment, they will fail to develop the mental capacities to do so.
There’s no specific, medical treatment for boredom. However, there are tons of solutions if you’re experiencing boredom. For example, you may want to consider trying some new hobbies or other new diversional activities. Joining a club can be a good way to thwart your boredom. Reading clubs, hobby groups, or exercise groups are all great places to start. Joining a community group that organizes activities and outings is another good idea.
