A pregnant person can generally enjoy a lazy river, a slow-moving, shallow water channel. This low-impact activity offers a feeling of weightlessness, which can relieve joint pressure and discomfort associated with pregnancy. However, this activity requires informed caution. Certain physical and environmental factors introduce risks that must be understood for a safer experience.
Physical Safety Concerns and Movement
The primary concern in a lazy river is the risk of abdominal trauma, which can occur from sudden impact or jarring movements. This risk is present if the inner tube collides forcefully with the side of the river or with other patrons’ tubes. The force from such an impact, especially against the abdomen, should be avoided to prevent potential complications like placental abruption (separation of the placenta from the uterus).
The pregnant person’s center of gravity shifts as pregnancy progresses, affecting balance and coordination. This change makes entering and exiting the inner tube or the water more difficult, requiring slow, controlled movements to prevent falls. While turbulence is generally minimal, excessive crowding can create unexpected jostling. Choosing off-peak times and less-trafficked sections minimizes the possibility of being bumped by others.
Addressing Water Quality and Infection Risk
While swimming is an approved form of exercise during pregnancy, the quality of the water in public recreational areas needs careful consideration. Even in properly treated water, common pathogens can pose a risk because the immune system is naturally weakened during pregnancy. Waterborne germs like Cryptosporidium are highly resistant to chlorine and can survive for over a week in adequately chlorinated water. Exposure to these germs, which can cause gastrointestinal distress, is a concern as severe dehydration from illness can lead to complications like contractions.
Other pathogens like E. coli and Giardia can be present, and ingesting even a small amount of contaminated water can lead to infection. Pregnant individuals are also more susceptible to vaginal or urinary tract infections from prolonged exposure to water where bacteria may thrive. To mitigate these risks, shower with soap before entering and immediately after leaving the water. Thoroughly drying the swimsuit area after swimming reduces the opportunity for bacterial or yeast growth.
Guidance on Temperature and Hydration
Pregnant individuals are more susceptible to overheating due to an increased metabolic rate and blood volume. An elevated core body temperature, particularly one exceeding 102.2 degrees Fahrenheit (39.2 degrees Celsius) for an extended period, can be a concern. This is particularly relevant in heated lazy rivers or during intense sun exposure. Spending time in a cool water environment can help regulate body temperature, but limiting the duration of the activity prevents the core temperature from rising too high.
Continuous hydration is equally important, even while submerged in water, because the body still loses fluids through sweat. Dehydration can trigger Braxton-Hicks contractions. Pregnant individuals should aim to drink at least 64 ounces of water daily, increasing this amount when spending time in the heat.
Wearing a wide-brimmed hat and sunscreen with an SPF of 30 or higher is advised. Seeking shade frequently helps to prevent heat-related issues and sun exposure.
