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.
Second, boredom typically occurs when people have trouble focusing their attention and they believe the reason for this difficulty is in the environment. When sitting in the airport, for example, there is probably a lot going on. There are people having conversations that you could listen to. You probably have something to read. There may be televisions showing the news. But, the stress of waiting for a delayed flight often makes it hard to concentrate, and so your mind jumps from one thing to another. You assume that this is caused by the environment, and so you feel boredom.
The people who heard the barely noticeable TV rated themselves as more bored than either the ones who heard the loud TV or heard no soundtrack. The idea is that both the loud TV and the soft TV were distracting, but for those who heard the loud TV it was clear why they were distracted from the article. Thus, they may have been frustrated with the noise, but they were not bored. Those who heard the soft soundtrack had difficulty concentrating, but they were not sure why, and so they attributed the difficulty concentrating to boredom.
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.
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.
Grunge lit is an Australian literary genre of fictional or semi-autobiographical writing in the early 1990s about young adults living in an "inner cit[y]" "...world of disintegrating futures where the only relief from...boredom was through a nihilistic pursuit of sex, violence, drugs and alcohol". Often the central characters are disfranchised, lacking drive and determination beyond the desire to satisfy their basic needs. It was typically written by "new, young authors" who examined "gritty, dirty, real existences" of everyday characters. It has been described as both a sub-set of dirty realism and an offshoot of Generation X literature. Stuart Glover states that the term "grunge lit" takes the term "grunge" from the "late 80s and early 90s—...Seattle [grunge] bands". Glover states that the term "grunge lit" was mainly a marketing term used by publishing companies; he states that most of the authors who have been categorized as "grunge lit" writers reject the label.
