> Braxton Hicks contractions are the uterus's way of practicing for labor, feeling like irregular, mild tightening that often resolves with rest or hydration.

Braxton Hicks contractions are the body's natural, often gentle, way of preparing the uterus for the work of labor, distinct from true labor contractions. As a trained full spectrum doula, I often hear from clients who are curious, and sometimes a little anxious, about these sensations. Understanding what they are can bring a lot of calm and clarity during your pregnancy.

## What it is

Braxton Hicks contractions are irregular, typically painless or mildly uncomfortable uterine tightenings that usually begin around 16–24 weeks of pregnancy, becoming more noticeable as you move into your third trimester. Think of them as your uterus's practice runs, getting ready for the main event. It's important to know that if these contractions remain irregular, brief, and stop when you rest or hydrate, they are generally not a sign that labor is starting. Leading organizations like ACOG and NHS agree on this point: in low-risk pregnancies, there's no evidence that Braxton Hicks cause cervical changes or trigger preterm labor.

These practice contractions can become more frequent in subsequent pregnancies, as your body has been through this before. Certain activities can also trigger them, such as physical activity, having a full bladder, sexual activity, or even dehydration. Just as you might notice shifts in your body like increased fatigue or even [Pregnancy Insomnia](/conditions/insomnia-pregnancy), Braxton Hicks are another common, normal physiological shift.

## What it tends to feel like

Many people describe Braxton Hicks as a generalized tightening or hardening of the abdomen, rather than a sharp pain. It might feel like your belly is briefly clenching up. The key differentiator from true labor contractions is their pattern: true labor contractions tend to get closer together, last longer, become stronger, and don't ease up with changes in position or hydration. Braxton Hicks, on the other hand, often fade away when you change what you're doing, rest, or drink some water. Tracking the frequency and duration of these sensations can be a really helpful way to understand what your body is doing.

## What the evidence says helps

One of the most common triggers for Braxton Hicks contractions is dehydration. This means that simply increasing your water intake can often help them subside. If you're feeling these tightenings, pausing for a glass of water and a moment of rest is a great first step. Changing your position can also be helpful; if you've been standing, try sitting down, or vice versa. Staying hydrated is a simple yet powerful step, much like how gentle movement can support your body through other pregnancy changes, even if you’re managing something like [Pregnancy Varicose Veins](/conditions/varicose-veins-pregnancy).

## Working with your care team

While Braxton Hicks are a normal part of pregnancy, it's always wise to stay in communication with your care provider. Tracking these patterns can offer clarity, similar to how observing other physical changes like [Melasma — Mask of Pregnancy](/conditions/melasma) helps you understand your body's unique journey. If you notice your contractions becoming regular, increasingly painful, or if they are accompanied by other symptoms like bleeding or a fluid leak, it's time to reach out to your provider. They are your best resource for understanding your specific situation and ensuring everything is progressing as it should.
