Swimming during pregnancy: Comfort and Practical Precautions

Swimming and water exercise can make movement feel easier during pregnancy because the water supports your weight. They may suit you when activity on land feels less comfortable. Choose a setting and level of effort that match your swimming ability, health and current symptoms.
Plan a manageable pool visit
If you are new to swimming for exercise, begin gently rather than trying to complete a set distance. Choose a pool where you feel confident entering, leaving and resting. Think about the practical parts of the visit too, such as changing facilities and whether you need help getting there.
Discuss swimming with your midwife first if you have a medical condition or pregnancy complications. Tell an instructor that you are pregnant. The pregnancy exercise guide explains how water activity can fit alongside other movement during the week.
Choose a comfortable stroke or class
There is no need to keep using a stroke that causes pain. Breaststroke leg movements can aggravate pelvic girdle pain because they spread the legs apart. Stop the painful movement and ask for advice on alternatives rather than assuming discomfort is an unavoidable part of pregnancy.
A pregnancy specific water class may offer adapted exercises and a chance to meet other people. Check that the instructor has suitable experience. A general aqua aerobics class is not automatically adapted simply because the exercises happen in water.
If pelvic pain also affects walking or turning in bed, tell your maternity team. The walking guide discusses when mobility symptoms need assessment.
Keep comfort and safety under review
Enter carefully rather than diving or jumping in. Avoid hot or very cold water, keep fluids available and leave the water if you feel unwell. Being in a pool does not remove the need to notice fatigue or new symptoms.
Bleeding, a possible waters leak or painful contractions needs maternity advice. Do not start a swim to see whether those symptoms settle. Seek emergency help for severe breathing difficulty, chest pain or collapse.
Treat open water as a separate decision
Lakes, rivers and the sea bring risks that a pool does not, including changing conditions and contamination. Speak with your clinician before open water swimming during pregnancy and follow local safety advice. Check current water quality alerts, especially after heavy rain, and avoid water with algae or scum.
Do not swim alone, and consider whether you can leave the water safely if you become tired. Avoid swallowing water, cover cuts and wash afterwards. If you become unwell after a swim, tell the clinician where and when you swam. A familiar location or apparently clear water does not establish that conditions are safe that day.
