Work & Pregnancy

If you are healthy and have no pregnancy complications, you can likely continue to work throughout your pregnancy. Certain types of work and working conditions however may pose concerns during pregnancy. A few small changes can make a difference to your comfort, your health, and the health of your baby.

Standing for Long Periods

  • Standing for long periods of time can affect the blood flow to your baby.
  • If possible, avoid standing for more than 4 hours at one time and after 30 weeks standing still for more than 30 minutes.
  • Take short walks throughout the day.
  • Rest once in a while with your feet up.
  • Alternate sitting, standing, walking when possible.
  • Wear comfortable, well-fitting shoes.
  • Ask for a stool at your work station.
  • Ask your health care provider if support stockings might help with circulation.

Sitting for Long Periods

  • Sitting for long periods of time may cause swelling in your legs and feet, less blood flow to your baby, and muscle strain and tension.
  • Use a cushion to support your back.
  • Use a footstool.
  • Rotate sitting and standing tasks.
  • Stand, stretch, or move around when possible.
  • Wear loose, comfortable clothing.

Heavy and Tiring Work

Heavy work includes lifting, pushing, pulling, and tiring work includes shift work, working more than 40 hours in a week, long commutes, and high levels of stress. This type of work may increase your chance of having problems during your pregnancy.

  • Avoid heavy lifting, pushing, pulling or carrying.
  • When lifting, bend your knees and keep your back straight.
  • Alternate heavy work with less tiring work.
  • Rest with your feet up, when possible.
  • Consider working fewer hours or options such as leaves or part-time work.
  • Reduce or avoid shift work as much as possible.
  • Get help if you are having a lot of workplace stress.

Physical Hazards

  • Extreme heat, loud noise, and radiation (i.e. x-rays) are all physical hazards.
  • Avoid long exposures to hot temperatures, loud noise, and whole body vibrations.
  • Protect yourself from the sun and heat.
  • Take safety precautions if working with x-rays.


Chemicals that can cause problems during pregnancy include lead, mercury, pesticides, cleaning products, and solvents. Chemicals can enter your body when you breathe, eat or drink, and through your skin.

  • Read the Material Safety Data Sheet of any chemical you are working with to learn about the risks and precautions.
  • Follow safety guidelines – use recommended safety equipment.
  • Wash your hands before eating.
  • Suggest safer products to your employer.


If you work with young children and pets or in a health care setting you may be exposed to infections such as chickenpox, fifth disease, cytomegalovirus, and toxoplasmosis. Infections may cause birth defects, miscarriage, and other problems. See the page on Preventing Infections for more information and on ways to stay safe.

More Ways to Keep Healthy at Work

  • Bring your own lunch or make healthier choices at work.
  • Keep healthy snacks handy.
  • Drink plenty of water. Limit drinks with caffeine such as coffee or tea.
  • Avoid smoking areas.
  • Take a walk on your breaks.
  • Rest and relax when you can.

Talk to your health care provider about the type of work you do. If concerns are raised, speak with your employer about how you can change the workplace or your day-to-day duties so you can reduce health risks and continue to work. Pregnant and breastfeeding women are protected under the Ontario Human Rights Code and have the right to be accommodated. Your health care provider can support your request. You can also check workplace safety guidelines or speak with your company’s occupational health and safety officer if they have one.
