Greater maternal stress during pregnancy is linked to increased infant illness in the first year, independent of postpartum stress. High stress can lead to preterm birth, low birth weight, and affect fetal brain development. Managing stress through healthy habits, support systems, and professional help is crucial for maternal and infant well-being.

How does maternal stress during pregnancy affect your baby's health?

Higher maternal stress during pregnancy is linked with significant increase in infant illness during the first year of life, independent of the level of stress after birth. Some stress can be normal during pregnancy, but chronic stress may cause maternal and infant health issues.It is common to experience some worries and anxiety during pregnancy. However, persistent or high stress levels may lead to health issues for the pregnant woman and unborn child.Research suggests that high stress levels in pregnancy may lead to:

Preterm birth: Increased risk of giving birth earlier, especially between 27-33 weeks of gestation.
Low birth weight: Babies born to stressed mothers tend to have lower birth weights.
Changes in fetal development: Stress can affect fetal brain development, potentially leading to cognitive and behavioral issues later in life.

Physiological effects

Cortisol Levels: Elevated cortisol due to stress can impact fetal development.
Inflammation: Chronic stress can lead to systemic inflammation, affecting maternal and fetal health.
Hormonal Changes: Stress-induced hormonal changes in the mother can have direct physiological impacts on the fetus.

Psychological and behavioural impacts

Anxiety and Depression: Stressed pregnant women are more likely to experience anxiety and depression, leading to adverse outcomes for both mother and child.
Unhealthy Behaviors: Stressed mothers may engage in unhealthy behaviors, such as poor diet, smoking and lack of exercise, which can compromise pregnancy outcomes.

To manage stress during pregnancy, consider these following tips:

Women can focus on eating healthy foods, getting regular exercise and getting enough sleep.

The woman should ask her spouse or family member to help with chores around the house and delegate work tasks wherever possible.

Learning what to expect during pregnancy, labor and looking after the newborn may help ease anxiety. The pregnant woman can also learn some relaxation and breathing techniques.
If the pregnant woman’s family encounters any problems related to their circumstances, such as financial or housing difficulties, talking with a social worker may help.
