Pregnant women can not soak in hot springs for 3 months, although the hot springs have the role of promoting blood circulation, eliminating fatigue and relieving foot swelling, but pregnant women are prone to early pregnancy reaction, infection, electrolyte imbalance, hypoxia and miscarriage, so it is not recommended that pregnant women soak in hot springs. 1, early pregnancy reaction: hot spring water temperature is higher than the normal temperature of the human body, pregnant women soak in hot springs will make pregnant women in a high temperature environment for a long time, the third trimester of pregnancy The fetus in the third trimester of pregnancy is more sensitive, and the high-temperature environment can easily trigger changes in the hormone levels of pregnant women, which can cause contractions or abnormal embryonic development; 2, infection: hot springs are public activities, and the hot spring water contains a large number of bacteria and viruses, so pregnant women with low immunity or skin wounds are susceptible to infection; 3, electrolyte imbalance: long time soaking in hot springs can cause a lack of water, sodium and potassium in the body, resulting in maternal electrolyte imbalance. Severe electrolyte imbalance can cause cardiac arrest or arrhythmia, which may cause fetal hypoxia, thus threatening the life of the fetus; 4, lack of oxygen: due to the large number of people in the hot springs, high temperature and high heat environment, less oxygen in the air, which can cause chest tightness, palpitations and respiratory distress, etc., maternal hypoxia can directly affect the fetal brain development, in serious cases, mental retardation, cerebral palsy, etc.; 5, miscarriage. The ground in the hot spring is slippery, and pregnant women are unstable and prone to slip and fall, which may cause abdominal pain, vaginal bleeding and other symptoms, and in serious cases, may cause miscarriage.
