Endorphins and Their Use in Labour
Endorphins are the body’s natural opioids, participating in pain relief, mood regulation, and stress responses. During labour, endorphin levels rise in response to pain and stress, which can influence the perception of pain, labour duration, and the emotional experience of childbirth. Here’s a concise overview of their role and practical considerations in labour.
What are endorphins?
Endorphins are endogenous (produced by the body) opioid peptides, primarily beta-endorphin, enkephalins, and dynorphins.
They bind to opioid receptors in the brain and spinal cord to reduce pain and induce feelings of well-being.
They are released in response to stress, pain, exercise, and certain sensory stimuli (e.g., touch, warm water).
How endorphins influence labour
Pain modulation: Endorphins help dampen the sensation of uterine contractions, potentially decreasing the perception of pain.
Emotional response: They contribute to the “euphoric” or dissociative feelings some people experience during intense contractions or pushing.
Labour progression: The analgesic effect can impact the subjective experience of contractions, which may influence coping strategies and labor dynamics.
Birth environment: A calm, supportive, and less stressful environment can promote natural endorphin release.
Factors that affect endorphin release during labour
Environment: Quiet, private, and non-stressful settings may enhance release.
Support: Continuous support from a partner, doula, or caregiver can reduce anxiety and facilitate endorphin production.
Breathing and relaxation: Slow, rhythmic breathing and relaxation techniques can modulate the stress response.
Movement and positioning: Changing positions, walking, upright positions, and gentle massage can influence pain perception and endorphin release.
Sound and touch: Calming sounds, massage, water immersion can promote endorphin release.
Breathing techniques and hypnobirthing: Methods that reduce fear and promote a sense of control may support endorphin-mediated analgesia.
There is evidence a TENS machine can increase the production of Endorphins.
