September is an exciting month in every college freshman’s life. For many, it’s the first time that they’ve left home to live in a new environment. But after the hustle and bustle (熙熙攘攘) of a few weeks, excitement gives way to a less enjoyable emotion— homesickness.

Homesickness manifests(显示) itself in many ways. You may miss mum’s cooking, your pets, or even your old bed. All this becomes a fond memory of the past. Homesickness can be a bitter feeling for many students, especially when faced with the challenges of settling into an unfamiliar environment.

But remember, you’re not alone. According to a recent BBC article, 70 percent of British college students experience homesickness. In this increasingly globalized world in which people migrate to faraway places for a relationship, education or work, homesickness is a feeling shared by many adults.

Homesickness can have similar symptoms to depression and in extreme cases it can develop into a panic attack. As for the term, homesickness or nostalgia wasn’t invented until the 17th century. It was considered a disorder by a Swiss physician, who attributed soldiers’ mental and physical discomfort to their longing to return home, “nostos” from Greek, and the accompanying pain, “algos”.

Studies in recent years, however, have shown that nostalgia may have some benefits to our mental health. After a decade of surveys and researches, Constantine Sedikides, a US social psychologist, found that nostalgia is what makes us human. He explains that nostalgia can resist loneliness, boredom and anxiety. Therefore, it’s necessary for college students to learn some ways to overcome the uncomfortable feeling.
