How to avoid passive smoking

Education and counselling to increase awareness of risks of passive smoking to mother and unborn child is needed. Mother, husband or partner, household members and caregivers also should be included in the discussion.

Do not allow people to smoke in your house or your car even if windows are kept open as the smoke lingers in air and settles on furniture, clothes and rugs leading to being inhaled later on as third hand smoking.

You should exercise your right to ask people who smoke to step outside. If you travel, choose restaurants, hotels and maybe even rental cars which are smoke-free.

Lots of studies are available to prove the side effects of passive smoking in pregnancy. We as society need to take care of the health of the mothers and our future generations.
