Guide | Should Pregnant Women Avoid Saunas and Hot Tubs? Understanding Heat-Related Risks
Although saunas and hot tubs may seem harmless, using them during pregnancy can pose risks to the pregnant woman and fetus. Hormonal changes make pregnant women more vulnerable to heat, which may cause overheating, fainting, dizziness, and dehydration. Medical experts advise particular caution to reduce these risks.
High heat can raise a pregnant woman's body temperature to 38°C or higher, similar to a fever, and may adversely affect the fetus. Research suggests that elevated body temperature early in pregnancy may increase the risk of neural tube defects, which affect development of the fetal brain or spinal cord and include spina bifida, anencephaly, and encephalocele. Because these defects usually develop early, experts advise avoiding saunas and hot tubs during the first six weeks of pregnancy.
Reducing risks during pregnancy
For pregnant women who still wish to use a sauna or hot tub, experts recommend these precautions:
Lower the water temperature: Keep hot-tub water below 35°C to reduce overheating.
Avoid full immersion: Keep the upper body above the water.
Limit exposure: Spend no more than 10 minutes in the tub.
Watch for symptoms: Leave immediately and cool down if dizziness, nausea, or rising body temperature occurs.
Stay away from heat sources: Avoid sitting near hot-tub heating jets.
The risks are lower after the first trimester, but body temperature and symptoms should still be monitored carefully.
What to do after accidental exposure
If a sauna or hot tub was used early in pregnancy, consult a doctor for prenatal assessment. Based on the temperature increase and symptoms, the doctor can determine whether further tests are needed to assess the risk of fetal neural tube defects. Evaluation commonly includes blood tests and ultrasound. Folic acid supplementation can also help reduce the risk of neural tube defects.
Experts suggest other ways to relax, such as gentle massage or a warm bath, to reduce potential heat-related risks to the pregnant woman and fetus.
