Saunas, Cold Plunges, and Hot Tubs During Pregnancy: Benefits and Risks

Pregnancy brings about many changes in a woman's body, requiring adjustments in lifestyle and daily activities, including how one manages thermal environments like saunas, cold plunges, and hot tubs. Here's a look at what expectant mothers might consider:
Saunas During Pregnancy
Benefits:
  • Relaxation: Saunas can offer relaxation, reducing stress, which is beneficial for both mother and baby.
  • Muscle Relief: The heat can soothe muscle aches and pains common during pregnancy.
  • Circulation: Some claim that saunas might enhance blood circulation, although this isn't conclusively proven for pregnant women.
Risks:
  • Overheating: The primary concern is the risk of raising your core body temperature, which could be harmful to the developing fetus, especially in the first trimester. Temperatures in saunas can reach 150-195°F (66-90°C), potentially elevating your core temperature beyond safe levels.
  • Dehydration: High heat exposure can lead to excessive sweating and dehydration, which is a risk during pregnancy.
  • Blood Pressure Changes: The heat might cause a drop in blood pressure, leading to dizziness or fainting, reducing blood flow to the baby.
  • Birth Defects: There's research suggesting an association between high heat exposure and neural tube defects or other developmental issues, particularly if exposure occurs early in pregnancy.
Recommendations:
  • Avoid saunas in the first trimester. If used in later trimesters, limit time to under 15 minutes, ensure you're well hydrated, and keep the temperature moderate. Always consult your healthcare provider.
Cold Plunges During Pregnancy
Benefits:
  • Inflammation Reduction: Cold water can help reduce inflammation and swelling, common in pregnancy.
  • Improved Circulation: Some believe it can invigorate circulation, although definitive research for pregnant women is limited.
Risks:
  • Vasoconstriction: Cold water might cause blood vessels to constrict, potentially reducing blood flow to the uterus.
  • Shock to the System: Sudden cold exposure could be startling or stressful, possibly affecting the fetus.
Recommendations:
  • If considering a cold plunge, ensure it's not extremely cold (avoid water temperatures below 50°F/10°C), keep sessions short, and check with your healthcare provider. Gradual exposure might be safer than sudden immersion.
Hot Tubs During Pregnancy
Benefits:
  • Relaxation: Similar to saunas, hot tubs can provide a soothing environment for relaxation.
  • Ease of Movement: The buoyancy can make movements easier, reducing joint stress.
Risks:
  • Overheating: Even more than saunas, hot tubs can quickly raise body temperature due to immersion in hot water (often at 100-104°F/38-40°C).
  • Dehydration: The risk of dehydration is significant, as you can lose a lot of fluids through sweating in a hot tub.
  • Neural Tube Defects: Similar concerns as with saunas regarding the potential impact on early fetal development.
Recommendations:
  • Most health organizations advise against hot tub use during pregnancy, especially in the first trimester. If approved by your healthcare provider in later stages, limit time to less than 10 minutes, keep the water temperature below 95°F (35°C), and avoid full submersion.

 

General Guidelines for Thermal Activities During Pregnancy:
  • Consult Your Provider: Always discuss with your healthcare provider before engaging in these activities. Individual health conditions can influence recommendations.
  • Hydration: Drink plenty of water before, during, and after any thermal exposure to avoid dehydration.
  • Time Limits: Keep sessions brief to prevent overheating or excessive cooling.
  • Core Temperature: Monitor your body temperature, aiming to keep it below 101°F (38.3°C) to minimize risks to the fetus.
  • Alternative Relaxation: Consider other forms of relaxation like warm (not hot) baths, prenatal yoga, or meditation, which are generally safer during pregnancy.
In conclusion, while saunas, cold plunges, and hot tubs can offer relaxation, the risks associated with them during pregnancy, particularly related to body temperature regulation, are significant. It's crucial to approach these activities with caution, understanding that what might be beneficial for one person could be detrimental for another, especially during pregnancy. Most importantly, listen to your body. If you feel like you are over-doing it, you probably are.
