Feeling cold during pregnancy is a common experience, even though many expect to feel warmer. The body undergoes numerous changes, and temperature fluctuations can be a perplexing symptom. This sensation of coldness is a frequent occurrence that can prompt questions about its origins. Understanding the physiological shifts and other factors contributing to this feeling can provide reassurance.
Hormonal and Metabolic Shifts During Pregnancy
Pregnancy initiates hormonal changes that influence the body’s temperature regulation. Progesterone, a hormone that rises during pregnancy, can affect body temperature, sometimes causing individuals to feel colder than usual. This hormonal influence can lead to fluctuations in how the body perceives and maintains warmth.
The body’s metabolic rate also increases as it works to support the developing fetus. While this increased metabolism generates heat, it can also lead to a sensation of cold, especially during periods of rest. Additionally, blood flow distribution changes, with increased circulation prioritizing the uterus and vital organs, which can temporarily reduce blood flow to the extremities, making hands and feet feel cold. The increase in blood volume during pregnancy, expanding by 20% to 30%, also affects heat distribution.
Common Underlying Factors
Beyond physiological adjustments of pregnancy, certain conditions can contribute to feeling cold. Anemia, a state of insufficient healthy red blood cells to carry oxygen, is common during pregnancy because blood volume increases, diluting red blood cells. Iron deficiency anemia, a frequent type, can make an individual feel cold because the blood is less effective at transporting oxygen and heat throughout the body. Symptoms of anemia can include extreme fatigue, weakness, dizziness, pale skin, and cold hands and feet.
Dehydration can also impact body temperature regulation, as adequate fluid balance affects circulation. Not drinking enough water can lead to lightheadedness and affect how the body distributes warmth, potentially causing a chilly sensation. Low blood sugar, or hypoglycemia, is another factor that can cause feelings of coldness or chills. This occurs when blood glucose levels drop below normal, impacting energy production and warmth maintenance. Symptoms of low blood sugar can include shakiness, weakness, dizziness, and cold sweats.
When to Consult a Healthcare Provider
While feeling cold during pregnancy can be a normal variation, certain accompanying symptoms warrant medical attention. Consult a healthcare provider if cold sensations are persistent or severe despite efforts to stay warm. Experiencing extreme fatigue, weakness, dizziness, or lightheadedness alongside coldness could indicate an underlying issue needing evaluation.
A fever or chills, particularly if sudden and intense, should prompt immediate medical contact, as this could signal an infection. Other concerning symptoms include shortness of breath, a rapid heart rate, or unusually pale skin. If coldness significantly interferes with daily activities or is accompanied by unexplained weight loss, seek professional medical advice to rule out conditions like thyroid issues or other deficiencies.
Managing Cold Sensations
Several practical strategies can help alleviate cold sensations during pregnancy. Dressing in multiple layers of clothing allows for easy adjustment to changing temperatures, promoting comfort. Opting for soft, breathable fabrics as a base layer, followed by warmer garments, can help retain heat effectively.
Maintaining proper hydration is beneficial, as fluids contribute to temperature regulation. Drinking warm beverages like herbal teas can provide both hydration and warmth. Ensuring adequate nutrition through regular, balanced meals helps maintain stable blood sugar levels, providing consistent energy for internal heat production. Light to moderate physical activity, such as walking, can improve circulation and generate body heat. Creating a warm environment at home, possibly with extra blankets or a space heater, can also contribute to comfort.
