A Physiology-First Birth & How We Can Support It
A Physiology First birth is an approach that centers and protects the natural physiological processes of labor and birth—those that unfold in the absence of unnecessary interference. The idea is simple but profound: birth works best when we support the body’s innate wisdom, rather than trying to control or override it.
A Physiology First model prioritizes:
The birthing person’s hormones, breath, and instincts
Movement, environment, and comfort
Unhindered maternal-fetal communication
The body’s built-in rhythm of labor and delivery
It recognizes that labor is a neuro-hormonal process—not just mechanical—and requires safety, privacy, and autonomy for optimal function.
Key Hormones in Physiological Birth
Understanding these hormones helps us support physiology:
Oxytocin: the “love hormone,” drives contractions and bonding
Endorphins: natural pain relief, promote euphoria
Adrenaline: stress hormone—too much can stall labor
Prolactin: supports lactation and mothering instincts
Disrupting this hormone cocktail—through fear, bright lights, restriction, or unnecessary interventions—can interfere with labor progress.
How to Support a Physiology First Birth
1.Create a Safe and Private Environment
Dim lighting, low voices, minimal interruptions
Familiar faces and calm energy
Limit unnecessary cervical checks or disruptions
2. Encourage Freedom of Movement
Let the birthing person change positions intuitively
Support walking, swaying, squatting, water immersion
Avoid restrictive fetal monitoring when possible
3. Protect the Golden Hour
Immediate skin-to-skin after birth
Allow time for the baby to self-initiate breastfeeding
Delay cord clamping and routine procedures unless medically necessary
4. Use Interventions Judiciously
Medical tools are life-saving when truly needed—but unnecessary use can derail physiology
Always ask: “Is this intervention truly needed right now? What are the alternatives?”
5. Provide Emotional Safety
Validate feelings, reduce fear, and offer continuous reassurance
Doulas, midwives, and informed partners are powerful protectors of physiology
Normalize intensity and help the birthing person feel in control
Why It Matters
A physiology-first approach has been associated with:5
Lower rates of cesarean and instrumental birth
Higher satisfaction with the birth experience
Improved breastfeeding outcomes
Lower risk of trauma or postpartum complications
