Contractions are the tightening and relaxing of uterine muscles during pregnancy. These sensations can be confusing, especially when they occur during sleep, so this article clarifies different types of contractions, whether they disrupt rest, and how to distinguish them.
Different Kinds of Contractions
During pregnancy, two primary types of contractions may occur: Braxton Hicks contractions and true labor contractions. Braxton Hicks, often called “practice” contractions, are the body’s preparation for childbirth. They are mild, irregular, and often painless, feeling like a tightening sensation in the abdomen. These contractions can be relieved by changing positions, walking, or hydrating, and they do not increase in intensity or frequency over time.
In contrast, true labor contractions are regular, becoming progressively stronger, longer, and closer together. They do not subside with changes in activity or position and cause changes to the cervix. The discomfort from true labor starts in the lower back and radiates to the front of the abdomen, and it can be intense enough to make talking or walking difficult.
Why Contractions May or May Not Wake You
Whether a contraction wakes someone from sleep depends on several factors, including its intensity and regularity. Mild, infrequent contractions, such as early Braxton Hicks or very early labor, are less likely to disrupt sleep. Stronger, more regular contractions are more noticeable and can easily rouse someone.
The stage of sleep also influences the likelihood of waking; a person in a deep sleep phase is less likely to be disturbed than someone in a lighter sleep stage. Individual pain thresholds vary significantly, meaning what one person might sleep through, another might find disruptive. Even strong Braxton Hicks contractions can be noticeable enough to disturb sleep, particularly in the later stages of pregnancy when the uterus is larger and more sensitive.
How to Tell What Kind of Contraction Woke You
If contractions awaken you, assessing their characteristics can help determine their type. Begin by timing the contractions: note how long each lasts (duration) and the interval from the start of one to the start of the next (frequency). True labor contractions follow a regular pattern, becoming consistently closer together.
Observe the intensity; true labor contractions increase in strength over time, while Braxton Hicks remain consistent or even weaken. Try changing your activity, such as walking around, standing up, or lying down, and drink some water. If the contractions ease or stop with movement or hydration, they are likely Braxton Hicks. True labor contractions will persist and may even intensify regardless of position changes. Also, note the location of the sensation; true labor pain begins in the lower back and wraps around to the abdomen, whereas Braxton Hicks are felt primarily in the front of the belly.
Steps to Take If Contractions Wake You
Upon waking to contractions, begin by calmly assessing their pattern and intensity. Timing the contractions for their duration and frequency will provide valuable information. Drink a glass of water and change your position, perhaps walking around the room or lying down on your side. Braxton Hicks contractions may lessen or disappear with hydration and movement.
If the contractions are irregular, mild, and subside, try to return to sleep or engage in relaxing activities. A warm bath or shower can offer comfort, as can listening to calming music or practicing deep breathing exercises. If the contractions seem to be progressing in regularity and intensity, prepare for the next steps, such as ensuring your hospital bag is ready.
When to Contact Your Healthcare Provider
Promptly contact your healthcare provider if contractions become consistently regular, strong, and increase in intensity and frequency, especially if they are approximately five minutes apart and lasting for at least an hour. Immediate medical attention is also necessary if your water breaks or if you experience any bright red vaginal bleeding.
A decrease in fetal movement or the sensation of severe, unmanageable pain also warrants an immediate call. When in doubt about the nature of contractions or any other pregnancy concern, always contact your healthcare provider for guidance.
