The experience of labor often includes involuntary shivering or trembling, widely known as “the shakes.” This physical response can range from mild tremors to more pronounced teeth-chattering or full-body shaking. While it can feel unsettling, this shaking is a common and normal part of the childbirth process. It is a temporary bodily reaction that can occur during various stages of labor and sometimes immediately after birth.
Understanding the Body’s Response
During labor, the body undergoes physiological changes that can trigger involuntary shaking. A significant factor is the surge of stress hormones like adrenaline, cortisol, and epinephrine. These hormones are released as part of the body’s natural “fight or flight” response to the intensity and pain of contractions, preparing the body for the physical demands of childbirth. This release can lead to increased heart rate and muscle tremors, manifesting as the shakes.
The body’s efforts to regulate its temperature also contribute to shivering during labor. Even if the environment is not cold, the body may attempt to maintain its core temperature in response to physical exertion. Hormonal shifts and the metabolic demands of labor can alter the body’s internal thermostat, leading to a sensation of coldness or shivering as a compensatory mechanism. This thermoregulatory response is a common reason for the tremors experienced.
Physical exertion during labor can also lead to muscle fatigue and trembling. Labor is a demanding process that requires significant energy expenditure, similar to intense athletic activity. The prolonged muscular work of contractions can deplete energy reserves, resulting in exhaustion that manifests as physical tremors or shakes. This fatigue can be particularly noticeable during the transition phase, when contractions are at their peak intensity.
Medical interventions, particularly epidural anesthesia, can also play a role in labor shakes. Epidurals can affect the body’s temperature regulation by causing blood vessels to dilate, which can lead to a sensation of cold or heat loss. The medications used in epidurals can also directly influence the central nervous system, sometimes inducing shivering as a side effect. Shivering is common after epidural administration.
Beyond hormonal and physiological shifts, the intensity of pain during labor can trigger a stress response that results in shaking. High pain levels activate the body’s stress pathways, leading to physical manifestations like shivering. This response is an involuntary reaction to the overwhelming sensations experienced during strong contractions.
Comfort Measures During Labor
While labor shakes are a normal response, several comfort measures can help manage the sensation. Providing warmth is often effective; warm blankets, socks, or a warm compress applied to the body can help alleviate shivering and promote relaxation. The physical warmth can counteract the body’s perceived coldness, even if actual body temperature is not low.
Maintaining adequate hydration is also important, as dehydration can contribute to feelings of fatigue and general discomfort during labor. Sipping on clear fluids or ice chips, if permitted by the healthcare provider, can help support the body.
Focused breathing techniques can offer a sense of control and help calm the nervous system. Concentrating on slow, deep breaths can reduce anxiety and potentially lessen the intensity of the shakes.
Changing positions and engaging in gentle movement can help alleviate discomfort and redirect the body’s energy. Walking, rocking, or using a birthing ball can provide a sense of agency and may reduce involuntary trembling. The presence of a supportive labor partner, doula, or nurse is also invaluable. They can offer physical comfort through gentle massage, comforting touch, or by providing reassurance that the shakes are a common and expected part of labor.
When to Consult a Healthcare Provider
While shaking during labor is normal, it’s important to consult a healthcare provider in specific situations. If the shaking becomes severe, persistent, or is accompanied by other concerning symptoms, inform the medical team. These symptoms might include a high fever, extreme pain unrelated to contractions, confusion, or difficulty breathing.
In most cases, labor shakes are a harmless and temporary physiological response to the changes occurring in the body. However, if there are any doubts or if the laboring person feels unwell, it is always best to inform the medical staff. They can assess the situation to ensure that the shaking is normal and not indicative of a less common underlying issue.
