What characterizes true labor contractions?

True labor contractions are characterized by their consistent strength and the fact that they do not decrease with rest. In true labor, contractions become progressively stronger, longer, and closer together over time, indicating that the body is preparing for delivery. Unlike false labor, such as Braxton Hicks contractions, the contractions in true labor are not relieved by activity or rest; rather, they persist and may intensify despite changes in position or efforts to relax.

The steady and increasing nature of true labor contractions plays a crucial role in the dilation and effacement of the cervix, facilitating the progression of labor. Understanding this characteristic is essential for differentiating true labor from false labor, which can often confuse expectant mothers.
