Cabin fever
is an idiomatic term for a claustrophobic reaction that takes place when a person or group is isolated or shut in a small space with nothing to do for an extended period. Cabin fever describes the extreme irritability and restlessness a person may feel in these situations.[1]
A person may experience cabin fever in a situation such as being in a simple country vacation cottage. When experiencing cabin fever, a person may tend to sleep, to have a distrust of anyone they are with or to have an urge to go outside even in the rain, snow, dark or hail. The phrase is also used humorously to indicate simple boredom from being home alone.[2]
