It is completely normal to feel some amount of stress during pregnancy, primarily because of the uncertainty that might come into play the first time you become pregnant. But if the stress and anxiety become constant, the effects on you and your baby could be lasting.
When you’re stressed, your body goes into “fight or flight” mode, sending out a burst of cortisol and other stress hormones. These are the same hormones that surge when you are in danger and they prepare you to run by sending a blast of fuel to your muscles and making your heart pump faster. In fact, constant stress could alter your body’s stress management system, causing it to overreact and trigger an inflammatory response. And inflammation, in turn, has been linked to poorer pregnancy health and developmental problems in babies down the road. Chronic stress may also contribute to subtle differences in brain development that might lead to behavioural issues as the baby grows.
