Tip 2: Keep circulation in mind when you are travelling

During pregnancy, your body increases blood volume to support the developing baby and your heart works harder to circulate it. Hormonal changes also affect blood vessel tone, which can influence how efficiently blood returns from the lower body. These are normal adaptations in pregnancy and are recognised in clinical guidance as part of expected physiological changes. When you spend long periods sitting or inactive during travel, these natural changes can become more noticeable, particularly in the legs. This is one reason why a journey that felt comfortable before pregnancy may feel quite different during pregnancy, even if the distance has not changed.

What you might notice during travel

Some people notice circulation changes more clearly during or after longer journeys, especially when routine movement is reduced.

This can include:

• Legs feeling heavier after long periods of sitting
• Mild swelling in feet or ankles
• Feeling more tired than expected after travel
• A sense of sluggishness when standing up again

These effects are usually temporary and improve once normal movement resumes.

Car journeys

Long car journeys mainly affect the body through sustained posture and reduced movement rather than the journey itself. Remaining seated for long periods can make circulation changes more noticeable, particularly at a later stage in pregnancy. One factor that is often overlooked is low-level whole-body vibration from road surfaces. While this does not harm the baby in normal circumstances, it can contribute to general fatigue in the pregnant body, particularly on longer or uneven journeys.

Interestingly, travel is usually experienced very differently by the baby than by the person carrying them. While a rough road, winding hill route or uneven surface may feel uncomfortable to you, the baby is cushioned by amniotic fluid, the uterus and surrounding maternal tissues. This natural cushioning means that normal travel movements are absorbed very differently inside the womb than they are by the person experiencing the journey. From a fetal safety perspective, there is no evidence that normal car travel affects the baby in uncomplicated pregnancies. UK guidance focuses instead on maternal comfort and reducing prolonged immobility.

Air travel

Air travel introduces a different environment due to cabin pressure and lower humidity. These conditions are normal for commercial flights and are generally considered safe for most uncomplicated pregnancies.

Guidance from the RCOG highlights that there is no evidence that flying itself causes miscarriage, early labour or waters breaking prematurely. For most pregnant people, the main considerations relate to comfort, movement and individual pregnancy circumstances rather than the aircraft itself. Many people assume the flight is the most demanding part of the journey. In reality, airports often involve long periods of standing, walking, carrying bags and waiting in queues before boarding even begins. This means the overall travel day can place more physical demand on the body than the time spent in the air. Another factor that is often overlooked is that pregnancy naturally increases the risk of blood clots. Although the overall risk remains low, longer periods of sitting during travel can contribute to this, which is one reason movement during longer journeys is commonly encouraged.

Air travel can also make some normal pregnancy symptoms feel more noticeable. The lower humidity inside aircraft cabins can contribute to feelings of dryness and fatigue, while changes in air pressure may make blocked noses or ear discomfort feel more pronounced. Some people also find that pregnancy sickness feels worse when combined with motion during travel. The main physical consideration during flights remains prolonged sitting and reduced movement, particularly on longer journeys where opportunities to change position may be more limited. The UK Civil Aviation Authority also advises that most people can fly during pregnancy, with recommendations focused on fitness to travel, comfort and awareness during longer journeys.

Cruises and ship travel

Cruise travel combines extended periods of sitting with gentle but continuous movement from the ship. This type of motion is generally well tolerated during pregnancy, although some people find it makes tiredness or nausea feel more noticeable. Unlike air travel or car journeys, cruises often follow structured daily routines with organised meals, activities and excursions. This can sometimes result in longer periods of sitting than you might experience at home. Ship movement itself is not considered harmful to the baby in normal circumstances. The main consideration is maternal comfort and how your body responds to ongoing motion and changes in routine. Access to medical care may also be more limited at sea compared with being on land, which is why planning ahead is commonly advised when travelling during pregnancy.

Supporting your circulation during travel

Rather than restricting travel, the focus in pregnancy is usually on small adjustments that help support circulation and comfort during longer journeys:

• Changing position regularly when seated
• Taking breaks to move when possible
• Avoiding long uninterrupted periods of sitting
• Noticing when your body feels tired and adjusting your pace accordingly
• Allowing recovery time after longer journeys

The aim is to support the body’s natural circulation changes rather than prevent normal travel activity.

Why routine changes matter

Changes in routine during travel can make it harder to notice early signs of fatigue or physical discomfort. Pregnancy already places additional demand on the cardiovascular system, which means the body may reach tiredness more quickly during periods of reduced movement. Travel can also make pregnancy feel slightly different in ways that are completely normal. For example, some people notice their baby seems quieter during a long journey and becomes more active once they arrive or settle down afterwards. The steady movement of a car, plane or other vehicle can sometimes have a soothing effect, which may influence how movement patterns are perceived during travel. Being aware of how your body feels during travel helps you adjust activity levels in real time, particularly during holidays or busy travel schedules. Equally, becoming familiar with your baby’s usual movement patterns can help you recognise when something feels different. If you are ever concerned about your baby’s movements, you should contact your maternity team for advice.

Final thoughts

Circulation changes are a normal part of pregnancy and can feel more noticeable during travel due to reduced movement, environmental changes and routine disruption. Simple awareness and small adjustments can help make journeys more comfortable without limiting normal travel activities. If you are ever unsure about symptoms or feel something is not right, you should contact your midwife or maternity team for advice.
