Pregnant women’s body temperature of 37℃ is usually normal because it will be high at the beginning of pregnancy due to the influence of hormonal changes in the body, but it will not reach the level of fever. The high body temperature in the early stage of pregnancy will be improved in the middle and late stage of pregnancy and the pregnant woman’s body temperature will return to the normal state. When a woman is pregnant, not only will her body temperature undergo some changes due to the influence of hormones, but also due to a series of early pregnancy symptoms such as pregnancy vomiting, nausea and loss of appetite, which can lead to stressful changes in the pregnant woman’s body temperature. However, if a pregnant woman finds that her body temperature exceeds 37.5℃, she should pay attention to it and go to the hospital for examination in time to find out the cause of the elevated body temperature, provide targeted treatment and follow the doctor’s advice on the use of medication, not to use it privately. Pay attention to rest and good rest habits, do not stay up late, do not work hard, pay attention to a balanced diet, do not eat spicy, stimulating, cold food. Pay attention to cold and warmth when you go out, prevent colds and flu, minimize going to public places where people are mixed, take folic acid and vitamins in time, keep your mood happy and have regular pregnancy tests.
