To combat jet lag, drink plenty of non-alcoholic fluids, eat healthy foods, exercise, and get plenty of rest. Try to adjust to the local time by avoiding naps. Exhaustion can make you overly emotional. If you are feeling particularly distressed or homesick during the first few days, try to get some rest. In most cases, the anxiety will subside once your body has time to adjust physically.
If you have a medical condition, tell people in your host country that can be of assistance. This includes your program director or faculty leader, local doctor, host family, or people in your dormitory that can help in an emergency.
Washing your hands often with soap and water removes potentially infectious material from your skin and helps prevent disease transmission. Waterless alcohol-based hand gels should be used when soap is not available.
The sun may be stronger in some locations than at home, especially at higher elevations. Use sunscreen and consider wearing a hat when you are outside.
Mosquitoes and other insects are carriers for disease. Use bug repellant, particularly in wooded or tropical areas. Mosquito nets may be a necessity in certain locations.
If you become sick with symptoms such as a fever accompanied by a cough, sore throat, or difficulty breathing or if you develop any illness that requires prompt medical attention, contact your program director or faculty leader immediately.
Do not travel while ill, unless you are seeking medical care. Limiting contact with others as much as possible can help prevent the spread of an infectious illness.
