It's natural to have difficulty adjusting to a new culture. People from other cultures may have grown up with values and beliefs that differ from yours. Because of these differences,the things they talk about, the ways they express themselves, and the importance of various ideas may be very different from what you are used to. But the good news is that culture shock is temporary.

What causes culture shock?

To understand culture shock helps to understand what culture is. You may know that genes determine a big part of how you look and act. What you might not know is that your environment has a big effect on your appearance and behavior as well.

Your environment is't just the air you breathe and the food you eat, though; a big part of your environment is culture.Culture is made up of the common things that members of a community learn from family, friends, media, literature, and even strangers. These are the things that influence how they look, act, and communicate. Often, you don't even know you're learning these things because they become second nature to you, for instance, the way you shake hands with someone when meeting them.

When you go to a new place, such as a new country or even a new city, you often enter a new culture that is different from the one you left. Sometimes your culture and the new culture are similar. Sometimes, they can be very different, and even contradictory. What might be perfectly normal in one culture, for instance,spending hours eating a meal with your family, might be unusal in a culture that values a more fast-paced lifestyle.

The differences between cultures can make it very difficult to adjust to the new surroundings that are very easy at home. Dealing with the differences can be very unsettling; those feelings are part of adjusting to a new culture.
