Does body temperature rise in early pregnancy?

In general, body temperature may rise during early pregnancy. Basal body temperature in early pregnancy typically increases by 0.3℃–0.5℃, maintaining a range of 36.8℃–37.2℃, which is considered a normal physiological phenomenon. If any discomfort occurs, it is recommended to seek medical attention promptly and receive targeted treatment under a doctor's guidance. The specific analysis is as follows:

During early pregnancy, the rise in progesterone hormone levels may cause a slight increase in basal body temperature, which is a normal occurrence. Progesterone helps maintain the stability of the uterine lining, providing a favorable environment for embryonic development. This temperature increase usually ranges between 0.3℃ and 0.5℃ and does not adversely affect either the pregnant woman or the fetus. However, if the woman’s body temperature remains persistently high—exceeding 37.5℃—or is accompanied by other symptoms such as headache, dizziness, or runny nose, it could indicate a cold or other illness, and timely medical evaluation and treatment are advised.

Throughout pregnancy, it is important to maintain healthy lifestyle and dietary habits, avoid excessive fatigue, and refrain from exposure to high-temperature environments to protect both maternal and fetal health.
