Braxton Hicks contractions usually stop within minutes when you drink water, change positions, or rest. These practice contractions are your uterus tightening and releasing as it prepares for labor, and unlike true labor, they respond quickly to simple interventions. The key is identifying what triggered them and removing that trigger.
Drink Water First
Dehydration is the single most common trigger for Braxton Hicks, and rehydrating is often the fastest way to make them stop. When your body is low on fluids, it releases a hormone called ADH that shares a molecular structure with oxytocin, the hormone that drives uterine contractions. That similarity can stimulate your uterus to contract even when labor isn’t starting. Drinking a full glass or two of water suppresses this hormonal response and often quiets the contractions within 15 to 30 minutes.
Pregnant women need significantly more water than usual. General recommendations call for 8 to 12 glasses per day (about 2.5 to 3 liters), with needs increasing as pregnancy progresses. By the third trimester, when Braxton Hicks are most frequent, you may need up to 15 glasses daily. If you’re noticing regular episodes of practice contractions, your fluid intake is the first thing worth examining.
Change Your Position
If you’ve been on your feet, sit or lie down. If you’ve been sitting for a while, stand up and take a short walk. Braxton Hicks often start during one sustained activity and resolve when you shift to something different. Kaiser Permanente recommends changing positions every 30 minutes and taking breaks during long periods of sitting.
Light physical tasks like vacuuming, carrying groceries, or lifting something heavy are frequent triggers. The exertion doesn’t need to be strenuous. If contractions start during activity, stop what you’re doing, sit down, put your feet up, and drink water. Most episodes will fade within minutes.
Try a Warm Bath
A warm (not hot) bath relaxes the uterine muscle and can stop Braxton Hicks that haven’t responded to water or rest alone. The warmth eases overall muscle tension, which reduces the tightening sensation across your belly. This works especially well for contractions that come in the evening after a long day. Keep the water comfortably warm rather than hot, since overheating raises your core temperature in ways that aren’t ideal during pregnancy.
Empty Your Bladder
A full bladder sits directly against the uterus and can irritate it enough to trigger contractions. This is one of the lesser-known triggers, but emptying your bladder regularly, especially before bed or before physical activity, can reduce how often Braxton Hicks occur. If contractions start and you realize you haven’t used the bathroom in a while, that’s worth trying before anything else.
Breathing and Relaxation Techniques
Braxton Hicks aren’t typically painful, but they can be uncomfortable, particularly later in pregnancy when they grow stronger. Slow, deep breathing during a contraction helps your body relax rather than tense against it. Breathe in through your nose for four counts, out through your mouth for six. This won’t necessarily stop the contraction faster, but it makes the experience more manageable and doubles as practice for labor breathing.
When Braxton Hicks Won’t Stop
The defining feature of Braxton Hicks is that they go away. True labor contractions don’t. ACOG recommends a simple test: rest, drink water, and time your contractions. If they stop, they were Braxton Hicks. If they continue, you may be in early labor.
Here’s how to tell the difference:
- Pattern: True labor contractions come at regular intervals and get closer together. Braxton Hicks are irregular and don’t follow a predictable rhythm.
- Intensity: True contractions steadily get stronger over time. Braxton Hicks stay about the same or may even start strong and then weaken.
- Location: True labor pain typically starts in the back and wraps around to the front. Braxton Hicks are usually felt only in the front of the abdomen.
- Response to rest: Braxton Hicks fade when you change activity, hydrate, or lie down. True contractions continue regardless.
If you’re before 37 weeks and experiencing six or more contractions in one hour that don’t stop with rest and hydration, contact your provider. That threshold is used by hospitals like UCSF as a triage guideline for possible preterm labor.
Reducing How Often They Happen
You can’t eliminate Braxton Hicks entirely. They’re a normal part of pregnancy, and they serve a purpose: toning the uterine muscle and helping soften and thin the cervix in preparation for delivery. Not everyone gets them, and there’s no clear explanation for why some people experience them frequently while others barely notice them.
That said, consistent habits reduce their frequency. Staying well hydrated throughout the day (not just when contractions start), emptying your bladder regularly, pacing yourself during physical tasks, and avoiding long stretches in one position all make a difference. Sex can also trigger Braxton Hicks, so if you notice them consistently afterward, that’s normal and not a reason for concern unless they don’t resolve with rest.
Some women find that maintaining adequate magnesium intake helps with general uterine irritability. Magnesium lowers calcium levels in muscle cells, and since calcium is required for muscles to contract, this has a relaxing effect on the uterus. Magnesium-rich foods like leafy greens, nuts, seeds, and whole grains are reasonable additions to a pregnancy diet, though you should discuss any supplementation with your provider since dosing matters.
