Homesickness is the distress or impairment caused by an actual or anticipated separation from the specific home environment or attachment objects. The term is in origin a loan translation of nostalgia, a learned term coined in Baroque period medicine. The Oxford English Dictionary describes homesickness as a feeling one has when missing home. Feelings of longing are often accompanied by anxiety and depression. These symptoms may range from mild to severe.
Homesickness frequently occurs when one travels and may be exacerbated by unfamiliar environments or foreign cultural contexts. Homesickness is especially common in youth. Young people may experience a sense of dread, helplessness, or separation anxiety on their first day of school, summer camp, or on a protracted summer vacation away from the family. Many first-year students at boarding schools or universities also experience homesickness. Some new members on military basic training and members on missions or deployments might also experience it.
