Unlocking Pregnancy Health — The Powerful Impact of Relaxation

Stress and anxiety during pregnancy are alarmingly common, affecting a significant proportion of expectant mothers today.¹ Soon-to-be moms usually struggle with persistent feelings of worry, tension and fear, often accompanied by symptoms such as elevated blood pressure and disrupted sleep patterns.

Recent studies present a concerning picture — Globally, 15% to 25% of pregnant women report high levels of stress and depressive symptoms.² The repercussions of unmanaged stress extend beyond immediate health concerns, leading to long-term developmental issues for the child and increased risk of postpartum complications for the mother, as discussed in the Journal of Perinatal and Neonatal Nursing.³

This underscores the critical need for effective interventions to identify and treat stress early in pregnancy, thereby improving obstetric and developmental outcomes for both mother and child.

Stress During Pregnancy — Causes, Outcomes and Conventional Treatment Options

The underlying causes of stress during pregnancy are multifaceted. Physical stressors, such as illness and discomfort, play a role, as do lifestyle changes and poor social support. Unplanned pregnancies and low financial income exacerbate stress levels.

Additionally, hormonal and physiological changes, anticipation of labor and delivery, and intimate partner violence during and after pregnancy contribute significantly to stress. These factors overwhelm an individual’s coping skills and resilience, leading to heightened stress levels.⁴

When these underlying causes are present, they trigger a cascade of physiological responses. The human body stores unresolved psychological stress in the musculoskeletal system, leading to sustained muscle contraction. This tension interferes with normal physiological functions, such as blood pressure and heart rate regulation.

Stress activates the Hypothalamus-Pituitary-Adrenal (HPA) axis and the immune system, increasing circulating glucocorticoids and proinflammatory markers. These biological changes impair the nervous system’s functions, leading to mental health issues.⁵

Stress during pregnancy is diagnosed through self-reported measures and physiological indicators. However, getting an accurate diagnosis could be challenging, as self-reported measures do not always accurately reflect the severity of stress, since some individuals tend to underreport their symptoms due to stigma or lack of awareness.

On the other hand, physical symptoms, while more objective, are influenced by various factors unrelated to stress, such as existing medical conditions or medications. This complexity leads to misdiagnosis or underdiagnosis, leaving some women without the necessary support and interventions.

Conventional methods to manage stress during pregnancy include counseling and pharmacological treatments. However, these approaches come with drawbacks. Counseling is time-consuming and not accessible to all, while pharmacological treatments carry potential risks for both the mother and the developing fetus.

The subjective nature of stress and its symptoms also complicate diagnosis. Hence, non-pharmacological interventions, such as relaxation therapies, are increasingly preferred due to their low-risk nature and potential scalability.

Relaxation Techniques Significantly Improve Pregnancy Outcomes

A recent study published in the PLoS One journal investigated the impact of various relaxation interventions on pregnant women’s mental health and birth outcomes. This comprehensive meta-analysis included 32 different studies with a total of 3,979 participants, all of whom were healthy pregnant women aged between 18 and 40 years.

The researchers aimed to determine whether practices like yoga, music therapy and deep breathing exercises could effectively reduce stress and improve both maternal and fetal health.⁶

The study focused on a diverse population of pregnant women from different countries and socioeconomic backgrounds, ensuring that the findings were broadly applicable. The results showed that relaxation interventions led to a notable decrease in maternal stress, anxiety and depressive symptoms.

Additionally, there was an observable improvement in birth weight, suggesting that these practices not only benefit the mother’s mental state but also have tangible effects on the baby’s health.

Delving deeper into the findings, the research revealed that relaxation therapy reduced maternal stress by an average of 4.1 points and anxiety by 5.04 points. Depressive symptoms also decreased by 2.3 points.

These reductions signify substantial improvements in the mental well-being of pregnant women, which is crucial for both their health and that of their unborn children. Furthermore, the study found that birth weight increased by an average of 80 grams, highlighting a positive outcome for newborns.

The authors note that the underlying mechanism why these effects are seen is because of the body-mind connection; your body, mind, brain and behavior are all closely interlinked, influencing one another. The researchers explain:

“Psychological stress leads to sustained contraction of muscle tissues making them tense with increased vasoconstriction, blood pressure, heart rate and decreased circulatory outcomes until the stress is resolved. Physical relaxation methods, such as breathing and muscle relaxation, further contract and then relax the muscle to expel the newly induced stress along with the preexisting pathological stress from the body.

Another mechanism is that psychological relaxations such as meditation and music therapies relax the mind, induce emotions, mental imagery, and counter unpleasant feelings and thoughts to improve mental well-being.”⁷

Even Short Sessions of Relaxation Therapy Exhibit Positive Results

The featured study also highlighted specific improvements in various physical, physiological and psychological indicators. Relaxation techniques helped optimize blood pressure, heart rate and respiratory rate among the participants.

These physiological benefits are essential as they contribute to the overall health of both the mother and the baby during pregnancy. Additionally, the duration of labor was reduced, making the birthing process smoother and less stressful for the mother.

“Physical responses to relaxation include immediate musculoskeletal relaxation and a decrease in muscle tension; psychological responses include mental calmness, silence and peace; and physiological responses to relaxation include optimized blood pressure, heart rate, respiratory rate and metabolic rate, along with decreased stress hormones and increased blood circulation.

Through one or a combination of these mechanisms, relaxation interventions could improve the health and well-being of pregnant woman, and this in turn may support fetal growth and development of the offspring,” the study authors said.⁸

The effectiveness of relaxation interventions varied based on the type of practice. Music therapy emerged as particularly effective in reducing stress, anxiety and depressive symptoms. On the other hand, progressive muscle relaxation and deep breathing exercises were more successful in increasing birth weight.

This differentiation suggests that while all relaxation techniques are beneficial, certain practices are more suited to addressing specific aspects of maternal and fetal health.

The study also explored the duration and frequency of these interventions. Participants engaged in relaxation practices ranging from brief sessions lasting about 10 minutes to longer routines, extending up to six months of daily practice. This variation indicates that even short-term relaxation techniques yield significant benefits, making them accessible and manageable for pregnant women with different schedules and commitments.

Biologically, the mechanisms behind these improvements are multifaceted. Relaxation interventions help reduce muscle tension caused by stress, which in turn optimizes physiological responses such as blood pressure and heart rate.

By fostering a state of calmness, these practices enhance neurogenesis and synaptogenesis, thereby improving mental health. Additionally, reducing stress-induced physiological strain leads to better overall health outcomes for both the mother and the baby.

Overall, the study underscores the importance of incorporating relaxation techniques into prenatal care, especially for low-income countries.⁹ The researchers concluded:

“Considering the magnitude of perinatal maternal mental health and psychological problems, the high burden of obstetric complications and the associated global burden of maternal and neonatal morbidity and mortality, the results of this review indicate that a range of complementary interventions may help address these problems.

[W]e recommend that these relaxation interventions be evaluated for their acceptability, suitability and effectiveness to improve maternal and offspring health outcomes in LICs [low-income countries].

Further evaluating the interventions in these settings would also be beneficial to understand whether, in places with severe food insecurity and a high burden of infections, which affect both maternal and infant health, relaxation interventions could mitigate the harmful effects of stressors.”¹⁰
