* Pregnant women are at an increased risk for falling and injury. Tubing can be a bumpy and fast-paced activity, and a pregnant woman could easily lose her balance and fall out of the tube. This could result in serious injuries to the mother and the baby.
* Pregnant women are more susceptible to heat-related illnesses, such as heat stroke. Tubing can be a very strenuous activity, and the heat from the sun can be overwhelming. This can lead to dehydration, dizziness, and even fainting.
* Pregnant women are at an increased risk for infection. The water in rivers can be contaminated with bacteria and viruses that can cause infections. These infections can be harmful to the mother and the baby.
