Breathing exercises may help some pregnant people cope with nausea by giving them a calm, simple way to relax, especially when sickness comes with stress or anxiety. Try gentle belly breathing: sit comfortably, breathe in slowly through your nose, then breathe out softly through your mouth without forcing the breath. Evidence is still limited, so breathing should support—not replace—food and fluid strategies or medical treatment when needed.
Pregnancy-related nausea can occur at any time of day, not just in the morning. Although slow breathing is not a guaranteed way to settle an upset stomach, it offers a simple relaxation technique that can be tried at home. Understanding how to practise it comfortably, what research suggests, and when to seek additional help can make it easier to decide whether it belongs in your pregnancy self-care routine.
Can breathing exercises help with pregnancy nausea?
Gentle breathing exercises are primarily a relaxation technique. They can help you slow down and feel calmer when nausea is accompanied by tension, worry, or anxiety. Some pregnant people may find that focusing on a steady breathing rhythm makes an uncomfortable episode easier to manage, although the response can vary.
Breathing exercises should not be presented as a proven cure for routine morning sickness. Pregnancy nausea can continue even when you feel relaxed, and breathing alone may not provide enough relief. A maternity resource from University Hospitals of North Midlands describes abdominal breathing as a relaxation method that can help people cope with stress, anxiety, and pain. This supports its use as a coping strategy rather than proof that it will stop pregnancy-related nausea.
How do you practise belly breathing during pregnancy?
Belly breathing, also called diaphragmatic breathing, involves breathing gently so that your abdomen moves naturally as you inhale and exhale. You do not need special equipment. Choose a quiet place where you can sit comfortably and concentrate on your breathing without feeling rushed.
- Find a comfortable position. Sit upright in a chair or on a bed with your back supported and your feet resting comfortably. Relax your shoulders, jaw, and hands.
- Rest a hand on your abdomen. Place one hand over your belly, just below your rib cage. This can help you notice its gentle movement as you breathe.
- Breathe in slowly through your nose. Allow your abdomen to expand naturally. Keep your breathing gentle rather than taking an unusually deep breath.
- Breathe out softly through your mouth. Let your abdomen settle as you exhale. Keep the breath smooth and comfortable, without pushing the air out or holding your breath.
- Repeat at an easy pace. Continue for about one or two minutes, or for as long as the exercise remains comfortable. Return to your usual breathing whenever you need a break.
The aim is to establish a calm, natural rhythm rather than to achieve a particular breathing rate. The antenatal guidance from University Hospitals of North Midlands describes slow breathing through the nose followed by a similarly slow exhalation through the mouth. If counting makes you feel tense, simply pay attention to the movement of your abdomen instead.
Which breathing techniques are worth trying?
1. Slow, steady breathing
This technique is useful when you want a simple exercise without concentrating on your abdominal movement. Breathe in gently through your nose, then breathe out slowly through your mouth. Allow the exhalation to last as long as or slightly longer than the inhalation, provided this feels natural.
Try it while sitting quietly when nausea begins or when you notice yourself becoming tense. Do not force a long exhalation or take repeated, unusually deep breaths. Comfortable breathing is more important than following an exact count.
2. Belly breathing with a relaxation image
You can combine gentle belly breathing with a calming mental image. For example, imagine a quiet garden, a familiar peaceful room, or another place where you feel comfortable. Keep your attention on the gentle rise and fall of your abdomen while allowing the image to occupy your thoughts.
This approach combines breathing with guided imagery, which is a relaxation method that uses mental pictures. It may help some people manage the distress that accompanies pregnancy sickness, but it should not be expected to work for everyone. Stop the exercise if concentrating on your breath or imagery makes you feel worse.
What does research say about breathing exercises for pregnancy sickness?
Research specifically examining breathing exercises for pregnancy-related nausea remains limited. A randomized controlled trial published in 2026 examined diaphragmatic breathing exercises delivered using a breathing exercise device, guided imagery, and a control group in pregnant women with hyperemesis gravidarum, a condition involving severe nausea and vomiting. All groups received routine anti-sickness treatment as part of the study.
The researchers reported improvements in nausea and vomiting scores and pregnancy-related anxiety in the breathing exercise and guided imagery groups. The findings, available through PubMed's record of the 2026 randomized controlled trial, are encouraging, but they need to be interpreted carefully. The study involved people receiving care for hyperemesis gravidarum and used a breathing exercise device. Its results do not establish how much ordinary, unassisted breathing exercises help all pregnant people with everyday nausea.
The practical conclusion is that gentle breathing may be worth trying as an additional coping technique. It is not a substitute for assessment or treatment when vomiting is persistent, symptoms interfere with daily activities, or hydration and nutrition are becoming difficult to maintain.
What else can you do alongside breathing exercises?
Breathing may fit into a broader routine of measures that reduce common sources of discomfort. The NHS guidance on vomiting and morning sickness recommends several self-care approaches that may help with pregnancy sickness:
- Eat small amounts frequently instead of relying on a few large meals.
- Try plain foods such as toast, crackers, rice, bread, or pasta if richer foods are difficult to tolerate.
- Keep away from smells and foods that seem to trigger nausea.
- Get enough rest, because tiredness can make nausea harder to manage.
- Take small, frequent sips of water or other suitable fluids to help maintain hydration.
You could practise slow breathing while sitting quietly before a meal or while resting after eating, provided this position feels comfortable. However, there is no need to schedule breathing around meals if it does not seem helpful. Focus on approaches you can tolerate, and do not delay eating or drinking when you need to do so.
If these measures are not enough, contact your maternity care provider about treatment options. The American College of Obstetricians and Gynecologists explains that treatment options are available for pregnancy-related nausea and vomiting, including vitamin B6 and doxylamine when appropriate. A clinician can help determine which options are suitable for your circumstances.
When should you seek medical help for pregnancy nausea?
Do not rely on breathing exercises alone if you are struggling to keep fluids down or if nausea and vomiting are affecting your ability to manage everyday activities. Persistent vomiting can lead to dehydration and inadequate nutrition. Severe pregnancy sickness, known as hyperemesis gravidarum, may require medical treatment and sometimes hospital care.
Contact your midwife, doctor, or maternity service promptly if you are vomiting and have any of the following concerns:
- You cannot keep food or fluids down for 24 hours.
- Your urine is very dark, or you have not urinated for more than eight hours.
- You feel very weak, dizzy, or faint when standing.
- You have abdominal pain, a fever, blood in your vomit, or unexplained weight loss.
These warning signs are consistent with the NHS advice on when to seek help for morning sickness. Seek urgent assessment if you feel seriously unwell or cannot maintain hydration. You do not need to wait until symptoms become extreme to ask for help.
Even without these warning signs, speak with your maternity team if nausea persists, worsens, or disrupts daily life. They can review your symptoms, how long they have lasted, your ability to eat and drink, and whether additional treatment would help.
How can you tell whether breathing exercises are helping?
There is no special test or required number of breathing sessions to complete. Instead, notice whether the exercise helps you feel calmer or makes an episode of nausea easier to cope with. You might find it useful at certain times of day but not at others, and it is acceptable to stop if you notice no benefit.
Keep the practice gentle. If you become dizzy, light-headed, unusually breathless, or uncomfortable, stop the exercise and return to normal breathing. Do not hold your breath or force deep inhalations. New or significant breathing difficulty during pregnancy needs medical attention rather than an attempt to manage it with a breathing technique.
Ultimately, slow belly breathing is a low-equipment relaxation option that some pregnant people may find useful alongside everyday nausea-management measures. Its role is supportive, and persistent or severe pregnancy sickness deserves appropriate medical care.
