Don't start if you are sick
Light-mindedness is more likely teenager's peculiarity. It is natural that you could feel sick before the trip itself. It is the result of extra excitement and good expectations. As a matter of fact, usually people take the vacation after a long and tiresome work period. That is why their immune and nervous system is rather weak and open to viruses and emotional breakdowns. If you feel the first symptoms of disease right before the trip, when the tickets and hotels are booked, ask the doctor what to do. In the case of emergency you could prevent disease while it is first-leveled. The things could be worse if you feel bad abroad or in the train, car or plane. Make sure that you are vaccinated against original illnesses, especially if you are going to the non-tourist country.
The pregnant women are to be careful as well. If you make a decision to travel even while you are expecting a baby, find the hospitals phone numbers and take care about insurance beforehand, learn the lows and guaranteed opportunities if you give a birth to your child abroad. And do not forget about extra money – you could need them. Actually, the doctors do not recommend or even forbid traveling in the later trimester. If it is possible, attend the health care course and first-aid course before traveling.
So, it is your health and you are the only person who should care of it. If the cautions are arranged, they are arranged for somebody to follow.
