Traveling abroad causes jet lag which affects the body. Taking care of your health and body while you are traveling is very important.

Chicago being a large city has its share of safety issues like any where else in the world. While most tourist places are safe to walk around in, one must certainly exercise caution after dark especially in areas like the Loop. This being primarily a business district gets lonely after working hours. As with other big cities, mugging does occur here too. It is advised to exercise normal precautionary measures like keeping your purse/handbag close to your body, not wearing expensive items of jewelry, sticking as much as possible to crowded areas, etc.
