Feeling a chill during pregnancy can be a surprising sensation. While many expect to feel warmer due to physiological changes, some find themselves reaching for an extra blanket. This common experience reflects the body’s adjustments as it nurtures a developing baby.
Why You Might Feel Colder
Hormonal shifts play a role in how your body regulates temperature during pregnancy. Rising progesterone levels increase basal body temperature. However, the body’s thermoregulation system works to maintain a stable internal environment, and these hormonal fluctuations can lead to a sensation of coldness as the body adapts.
The circulatory system undergoes modifications to support the growing fetus. Blood volume can increase by up to 50% by the third trimester, but this expanded volume is prioritized to supply the uterus and placenta. This redirection of blood flow can result in reduced circulation to your extremities, such as hands and feet, making them feel cooler.
Metabolic adjustments also contribute to temperature perception. Pregnancy generally increases your metabolic rate to provide energy for you and the baby, generating heat. The body’s cooling mechanisms might become more active to dissipate this extra heat, leading to a sensation of coldness as it attempts to cool itself. This can make you feel cold even in warm environments.
Iron deficiency anemia is a common condition during pregnancy. Your body requires more iron to produce red blood cells, which carry oxygen to your tissues and the developing baby. Insufficient iron can lead to fewer healthy red blood cells, impairing oxygen transport and contributing to coldness, fatigue, and paleness.
When to Consult Your Doctor
While feeling cold during pregnancy is often a normal response, certain accompanying symptoms warrant medical evaluation. Persistent or severe coldness, especially if unusual, should be discussed with your healthcare provider. This allows for a thorough assessment to rule out any underlying conditions.
If coldness is accompanied by extreme fatigue, unusual weakness, or pale skin, it could indicate anemia. Shortness of breath, dizziness, or lightheadedness are additional signs that, when combined with feeling cold, suggest a check-up for potential iron deficiency. Your doctor can perform blood tests to check iron levels and recommend appropriate treatment.
Thyroid issues, specifically hypothyroidism (an underactive thyroid), can also cause coldness. Other symptoms include persistent tiredness, weight gain, constipation, and muscle cramps. Since thyroid hormones are crucial for regulating metabolism and body temperature, discuss any concerns with your doctor for proper diagnosis and management. A sudden onset of intense coldness or chills accompanied by a fever suggests an infection and requires immediate medical attention.
Staying Comfortable
Managing coldness during pregnancy often involves simple adjustments. Dressing in multiple layers allows you to adapt to temperature fluctuations, adding or removing clothing as your body’s warmth changes. Opting for natural, breathable fabrics can help regulate your body temperature effectively.
Maintaining adequate hydration is important and can support your body’s circulatory function. Drinking plenty of fluids, including warm beverages like herbal teas, can help you feel warmer and support increased blood volume. Ensuring a nutritious diet rich in iron and other essential nutrients provides your body with the energy it needs to regulate temperature and support the demands of pregnancy.
Light physical activity, if approved by your healthcare provider, can improve circulation and generate warmth. Gentle exercises can help maintain blood flow to your extremities, potentially reducing cold hands and feet. Creating a comfortable home environment by adjusting thermostats or using warm blankets can also contribute to your comfort.
