Labor shakes—have you heard of them or experienced them firsthand? Many women report uncontrollable shivering before, during, or after labor, even when they’re not cold. What causes these mysterious body tremors during such a powerful moment?
Labor shakes are a completely normal physiological response triggered by hormone shifts, adrenaline surges, or rapid changes in the body during labor and delivery. Some women feel them during transition (the most intense stage), while others experience them after giving birth. According to childbirth experts like Penny Simkin, labor shakes are harmless and usually resolve on their own.
But don’t panic if your teeth chattering—there’s more to the story. Want to know why these shakes happen, how long they last, and how to manage them during delivery? Let’s unpack the science and support behind this surprising labor symptom.
What Are the Labor Shakes?
Labor shakes, also referred to as “childbirth shivers” or “delivery tremors,” are sudden, uncontrollable shivers or trembling that many women experience during labor or immediately postpartum. These shakes are not related to feeling cold and can affect the entire body or just the arms and legs.
Some women experience violent shaking that makes it difficult to hold objects or remain still, while others may feel just mild tremors. Importantly, these shakes are not harmful in themselves and often resolve on their own without medical intervention. Though they may look distressing, they are a well-documented and normal aspect of the labor process.
What Causes Shaking During Labor?
There is no single cause behind labor shakes, but several physiological and emotional factors contribute to their onset:
1. Hormonal Fluctuations
Labor triggers a rapid shift in hormone levels, particularly adrenaline, oxytocin, and endorphins. These chemical changes affect the nervous system, sometimes resulting in tremors. The release of adrenaline, in particular, primes the body for the intense effort of labor, similar to a fight-or-flight response that can cause shaking.
2. Physical Exhaustion
Childbirth is an intense physical event that can last for hours, leaving a woman’s body tired, strained, and depleted. Muscle fatigue and overexertion—especially after pushing or prolonged contractions—can lead to uncontrollable shaking.
3. Pain and Emotional Stress
The pain of labor, combined with fear, anxiety, or even relief, can overwhelm the nervous system. Just like shivering from fear or excitement, labor shakes can be a physical outlet for extreme emotion.
4. Temperature Regulation
Interestingly, labor shakes are often not caused by feeling cold, but internal changes in body temperature may still play a role. For instance, the body may lose heat due to blood loss or IV fluids, especially in an operating room or birth suite kept at cooler temperatures.
5. Anesthesia or Medications
Epidurals and spinal blocks are commonly used during labor and can sometimes lead to chills and shaking, especially if the body is reacting to the medication or the insertion procedure. Shaking may also occur as a side effect of some drugs administered during delivery.
6. Transition Phase of Labor
Many women report shaking during the “transition” phase of labor—the point where the cervix dilates from 7 to 10 centimeters. This is one of the most intense parts of labor and frequently involves a dramatic surge of hormones.
Is It Normal to Have Continued Shaking or Postpartum Chills?
Yes, postpartum chills or continued shaking after delivery are completely normal in most cases. Many women experience them immediately following birth, whether they delivered vaginally or via epidural or C-section. This reaction is often due to a sudden drop in adrenaline and a release of tension that has been building throughout labor.
Additionally, blood loss, IV fluids, and shifting hormone levels contribute to this reaction. These chills typically last a few minutes to an hour and resolve on their own.
However, if the shaking is accompanied by a fever, signs of infection, or doesn’t subside, it’s important to alert medical staff. Rarely, postpartum chills may signal a complication such as an infection, hemorrhage, or reaction to anesthesia.
What Stage of Labor Do You Get the Shakes?
Labor shakes can occur during any stage of labor, but are most commonly associated with:
- Transition Phase: As mentioned, this is the most common time to experience shakes. It marks the shift from the first to second stage of labor and is characterized by strong, frequent contractions.
- Immediately After vaginal and cesarean Birth: Many women experience a wave of shaking within minutes after delivering their baby. This is due to the combination of emotional release, hormonal drop, and physical fatigue.
- During Epidural Administration: Some women experience tremors or chills as a reaction to the epidural process, either during administration or after the effects kick in.
- Postpartum Recovery: Some degree of shaking may continue during pregnancy or the early postpartum period, particularly in the delivery room or first few hours post-birth.
Understanding when the shakes occur can help you feel more prepared and less alarmed if they do happen.
How Can You Calm the Labor Shakes?
While labor shakes often subside on their own, there are several comforting and effective strategies to help manage or ease the experience:
- Warm Blankets: Even though the shakes aren’t typically caused by cold, warm blankets can provide comfort and help regulate body temperature.
- Deep Breathing: Controlled breathing helps calm the nervous system and reduces anxiety, which can lessen the intensity of shaking.
- Emotional Support: Having a supportive partner, doula, or midwife nearby can make a big difference in emotional comfort, which often reduces physical symptoms.
- Positioning: Changing your position in bed, sitting up, or lying down in a different posture can sometimes help minimize tremors.
- Hydration and Nutrition: Low blood sugar or dehydration can contribute to shakiness, so sipping water or having a small snack (if permitted) might help.
- Massage or Touch: Gentle touch, massage, or even hand-holding can provide grounding and calm to help ride out the shakes.
Remember, don’t panic if your body starts to shake. Let your care provider know so they can monitor you, but in most cases, nothing needs to be done medically unless other symptoms arise.
How a Doula Can Help During Labor?
A doula—a trained, non-medical labor support person—can be an invaluable resource during childbirth, especially when managing labor shakes.
Here’s how a doula supports you:
- Emotional Reassurance: One of the doula’s main roles is to provide calming, continuous emotional support. When labor shakes occur, a doula can offer reassurance that the shakes are normal and nothing to fear.
- Comfort Measures: Doulas are skilled in techniques like counter-pressure, massage, breathing guidance, and movement strategies that can ease discomfort and reduce stress-induced tremors.
- Partner Support: A doula helps guide your partner in offering appropriate support, which adds another layer of calm and stability.
- Environmental conscious Control: Doulas can help adjust lighting, music, temperature, and room ambiance to promote a soothing environment that minimizes anxiety.
- Advocacy: A doula helps ensure your voice is heard, which can reduce stress and increase confidence—key elements in managing physical symptoms like labor shakes.
Having a doula may not prevent labor shakes, but their calming presence can reduce their severity and duration, making for a more empowered birth experience.
Commonly Asked Questions about Shivering During Labor (FAQs)
What are labor shakes?
Labor shakes refer to involuntary shaking or shivering that some women experience during labor. This phenomenon is often attributed to hormonal fluctuations and the body’s response to stress hormones like adrenaline and cortisol, which surge during contractions.
Why do women shake during labor?
Women may shake during labor due to a combination of stress, hormonal changes, and physical exertion. The release of oxytocin during contractions and the body’s heightened state of awareness can lead to uncontrollable shaking, especially in the transition stage of labor.
Are labor shakes normal?
Yes, labor shakes are considered normal and are a common response to the intense experience of giving birth. Women can shake uncontrollably as their bodies adjust to the significant physical and emotional changes that occur during labor and delivery.
When do labor shakes start?
Labor shakes can occur at various stages of labor, but they are most commonly reported during the transition phase, which is the time just before the baby is born. Some women might also experience shaking right after birth as their body begins to recover from the labor process.
What can help calm shaking during labor?
Warm blankets and skin-to-skin contact with the newborn can help soothe and calm the shaking. Additionally, a supportive environment provided by a nurse or doula can aid in reducing stress and promoting relaxation during labor.
Do labor shakes affect the baby?
No, labor shakes do not affect the baby. They are a normal physiological response of the mother during labor and are not harmful to the infant. The baby’s health is monitored throughout the labor process to ensure everything is proceeding smoothly.
Can medication contribute to shaking during labor?
Certain medications, including epidurals and spinal anesthesia, can influence the body’s response during labor, potentially leading to shaking. However, the involuntary shaking is primarily linked to hormonal changes and stress, rather than solely medication effects.
What should I expect immediately after birth regarding shaking?
Right after birth, many women report experiencing labor shakes as the body adjusts to its new state. Hormonal shifts and the sudden drop in adrenaline can lead to temporary shaking, which usually resolves quickly as the body stabilizes.
How can I prepare for shaking during labor?
Understanding that labor shakes are a normal part of the experience can help alleviate anxiety. Discussing concerns with your certified nurse-midwife or doula beforehand can also provide reassurance and strategies for managing discomfort during labor and delivery.
Conclusion
Experiencing labor shakes can be unsettling, but rest assured—they are a common, natural, and typically harmless part of childbirth. Whether they occur during the intense transition stage or shortly after delivery, labor shakes are your body’s way of adjusting to the extreme physical and emotional demands of birth.
Understanding what causes these tremors, when they’re most likely to occur, and how to manage them can go a long way in helping you stay calm and focused during your labor journey. With the right support, including the potential involvement of a doula, you can navigate labor with confidence—even when unexpected symptoms arise.
If you’re pregnant or planning for labor, speak with your healthcare provider or birthing team about what to expect, including labor shakes, so you feel prepared and empowered every step of the way.
