Can pregnant women travel long distances?

It is recommended not to travel during pregnancy, because the following situations may occur during travel, which are more dangerous to the mother and fetus. During travel, radio wave fatigue is inevitable. These conditions can easily induce uterine contractions, leading to miscarriage and premature birth. During transportation such as trains and airplanes, the air circulation is poor and respiratory infections are prone to occur. When staying in a hotel, the sanitary conditions of the hotel are poor, and there is a risk of vaginitis and uterine infection. In addition, if uterine contractions occur during the trip, it will be difficult to seek medical treatment.
