Return to top Stay Healthy Getting sick or injured on vacation can put a major damper on the fun. Don't let it happen to you. If you've got a long flight, bring a bottle of water and stay hydrated. Pressurized air is very drying and dehydration can make you feel run down. Hydration can also help stave off the effects of jet lag.
Eye drops can help keep eyes from getting dry and itchy.
If you have sinus problems or a cold, carry decongestants with you on the flight. The additional pressure on already pressured sinuses can be very painful. Pack prescription medicines in your carry-on luggage. Keep them in their original bottles, both for the information the bottles provide and to prevent suspicious looks if your luggage is searched at the airport. Pack an extra pair of prescription eyeglasses.
