These studies led to the conclusion that the coping strategies that are likely among nostalgia-prone people often lead to benefits during stressful times. Batcho (2013) found that nostalgia proneness positively related to successful methods of coping throughout all stages-planning and implementing strategies, and reframing the issue positively. One way to improve mood is to effectively cope with problems that hinder one's happiness. Improving mood Īlthough nostalgia is often triggered by negative feelings, it results in increasing one's mood and heightening positive emotions, which can stem from feelings of warmth or coping resulting from nostalgic reflections. Such benefits may lead to a chronic disposition or personality trait of 'nostalgia proneness.' Nostalgia has also been associated with learning and memory consolidation. Many nostalgic reflections serve more than one function, and overall seem to benefit those who experience them.

Nostalgia has been found to have important psychological functions, such as to improve mood, increase social connectedness, enhance positive self-regard, and provide existential meaning. The modern view is that nostalgia is an independent, and even positive, emotion that many people experience often. Consistent with its Greek word roots meaning 'homecoming' and 'pain,' nostalgia was for centuries considered a potentially debilitating and sometimes fatal medical condition expressing extreme homesickness. Nostalgia's definition has changed greatly over time. Cultural phenomena such as music, movies, television shows, and video games, as well as natural phenomena such as weather and environment can also be strong triggers of nostalgia. These recollections of one's past are usually important events, people one cares about, and places where one has spent time. Emotion is a strong evoker of nostalgia due to the processing of these stimuli first passing through the amygdala, the emotional seat of the brain. The scientific literature on nostalgia usually refers to nostalgia regarding one's personal life and has mainly studied the effects of nostalgia as induced during these studies. When applied to one's beliefs about a society or institution, this is called declinism, which has been described as 'a trick of the mind' and as 'an emotional strategy, something comforting to snuggle up to when the present day seems intolerably bleak.' There is a predisposition, caused by cognitive biases such as rosy retrospection, for people to view the past more favourably and future more negatively. Nostalgia is associated with a longing for the past, its personalities, possibilities, and events, especially the ' good ol' days' or a 'warm childhood'.

Described as a medical condition-a form of melancholy-in the Early Modern period, it became an important trope in Romanticism. The word nostalgia is a learned formation of a Greek compound, consisting of νόστος ( nóstos), meaning 'homecoming', a Homeric word, and ἄλγος ( álgos), meaning 'sorrow' or 'despair', and was coined by a 17th-century medical student to describe the anxieties displayed by Swiss mercenaries fighting away from home. Nostalgia is a sentimentality for the past, typically for a period or place with happy personal associations.
