What is the significance of Braxton Hicks contractions?

Braxton Hicks contractions are often referred to as "practice contractions" because they help prepare the uterus for the actual labor process. These contractions can occur at any point during pregnancy, although they are more commonly recognized in the second and third trimesters. Their significance lies in their role of toning the uterine muscles and promoting blood flow to the placenta, thus supporting the developing fetus.

These contractions are typically irregular and can be undetected by some pregnant individuals. They don't indicate the onset of labor, nor should they be confused with actual labor contractions, which are regular, increasing in intensity, and lead to cervical dilation. Additionally, Braxton Hicks contractions are not related to any fetal distress, nor are they restricted to just the third trimester. Understanding these contractions helps women differentiate between false labor and the signs of impending labor, providing reassurance and knowledge about their pregnancy.
