Pregnancy can sometimes make you feel cold due to hormonal changes and altered blood circulation, though it varies widely by individual.
Understanding Body Temperature Changes During Pregnancy
Pregnancy triggers a whirlwind of changes in a woman’s body, from hormonal shifts to cardiovascular adjustments. While many associate pregnancy with feeling warm or experiencing hot flashes, it’s less common—but entirely possible—to feel cold during this time. The question “Does Pregnancy Cause You To Be Cold?” isn’t straightforward because body temperature regulation during pregnancy is complex.
Early in pregnancy, the hormone progesterone rises sharply. Progesterone is known to increase basal body temperature slightly, which often causes women to feel warmer than usual. However, as pregnancy progresses, other factors come into play that can alter this sensation. Blood volume increases by nearly 50%, and the heart pumps more blood to support the growing fetus. These circulatory changes can sometimes lead to feelings of chilliness, especially if blood flow to extremities is reduced.
In addition, some pregnant women experience anemia—a condition marked by low red blood cell counts or hemoglobin levels—which reduces oxygen delivery throughout the body and can cause cold hands and feet. Nutritional deficiencies or thyroid imbalances during pregnancy can also contribute to feeling cold unexpectedly.
Hormonal Influence on Temperature Regulation
Hormones are the puppeteers behind many bodily functions during pregnancy. Progesterone raises core temperature slightly after ovulation and in early pregnancy, but estrogen levels also surge later on. Estrogen affects blood vessel dilation and constriction, which influences heat retention and loss.
Progesterone’s thermogenic effect means many pregnant women feel warmer overall; however, fluctuations in these hormones can sometimes disrupt normal temperature regulation. When progesterone dips or fluctuates—common in the first trimester—women may notice chills or cold sensations.
Moreover, thyroid hormones play a significant role in metabolism and heat production. Pregnancy demands increased thyroid activity to support fetal development; if this balance is off due to hypothyroidism (underactive thyroid), it may cause sensitivity to cold.
Circulatory Changes That Can Make You Feel Cold
Blood volume increases dramatically during pregnancy—up to 50% more than pre-pregnancy levels—to supply oxygen and nutrients to both mother and baby. While this sounds like it should make you feel warmer, it actually can cause uneven blood flow distribution.
The heart works harder but sometimes pumps less efficiently due to the increased workload. This means peripheral circulation (blood flow to hands and feet) might decrease temporarily, causing those areas to feel cold or numb.
Varicose veins and swelling (edema) are common side effects of altered circulation during pregnancy. These conditions can further impair warmth sensation in limbs because blood pools instead of circulating smoothly.
Anemia: A Common Culprit Behind Feeling Cold
Anemia affects approximately 15-25% of pregnant women worldwide. It occurs when red blood cells or hemoglobin levels drop below normal thresholds, reducing oxygen transport throughout the body.
Oxygen fuels cellular metabolism—the process that generates heat internally—so when oxygen delivery is compromised, it’s natural for a woman to feel cold more easily. Symptoms of anemia include fatigue, dizziness, shortness of breath, pale skin, and chills or cold extremities.
Iron deficiency is the most frequent cause of anemia during pregnancy because iron demands rise significantly as the fetus grows. Without enough iron intake through diet or supplements, anemia develops gradually but noticeably impacts how warm or cold a woman feels.
Nutritional Factors Influencing Cold Sensitivity
Nutrition plays an enormous role in maintaining healthy body temperature regulation during pregnancy. Deficiencies in iron, vitamin B12, folate, and other micronutrients can impair red blood cell production and energy metabolism.
Pregnant women often struggle with nausea and food aversions that limit nutrient intake. If caloric intake drops drastically or meals become irregular due to morning sickness or food sensitivities, metabolism slows down—and so does heat generation.
Eating small frequent meals rich in protein and complex carbohydrates helps sustain energy levels throughout the day while supporting stable blood sugar levels—a key factor in feeling comfortably warm.
Thyroid Function During Pregnancy
The thyroid gland regulates metabolism through hormone secretion (T3 and T4). These hormones control how quickly cells convert nutrients into energy—and ultimately heat.
Pregnancy increases demand on the thyroid gland by about 30-50%. If this demand isn’t met adequately because of iodine deficiency or autoimmune thyroid disease (like Hashimoto’s), hypothyroidism may develop.
Hypothyroid symptoms include fatigue, weight gain, dry skin—and yes—feeling unusually cold even when others are comfortable. Monitoring thyroid hormone levels through routine prenatal care is essential for managing this condition effectively.
The Role of Immune System Changes on Feeling Cold
Pregnancy modulates immune function so the mother’s body tolerates the fetus without rejection—this involves a delicate balance between immune activation and suppression.
Some immune responses mimic mild infection symptoms such as chills or shivering even without fever present. This immune shift can occasionally trigger sensations of being cold intermittently during certain trimesters.
Moreover, increased susceptibility to viral infections during pregnancy means catching a mild cold might be more common—and chills often accompany such illnesses regardless of pregnancy status.
Summary Table: Causes & Effects Linked To Feeling Cold During Pregnancy
| Cause | Description | Effect on Body Temperature |
|---|---|---|
| Hormonal Fluctuations | Changes in progesterone & estrogen impacting thermoregulation. | Mild rises or dips causing warmth or chills. |
| Circultory Adjustments | Increased blood volume & heart workload affecting peripheral flow. | Cold hands/feet due to reduced circulation. |
| Anemia (Iron Deficiency) | Lack of sufficient red blood cells lowering oxygen delivery. | Sensation of chilliness & fatigue. |
| Nutritional Deficiencies | Poor intake of iron/B12/folate slowing metabolism. | Diminished internal heat production. |
| Thyroid Imbalance | Poor thyroid hormone output lowering metabolic rate. | Sensitivity to cold despite ambient temperature. |
The Emotional Impact of Feeling Cold During Pregnancy
Feeling persistently cold when everyone else feels warm can be frustrating for expectant mothers already navigating physical discomforts. This sensation might lead some women to worry about their health or fetal wellbeing unnecessarily.
However, understanding that feeling chilly occasionally is usually harmless helps reduce anxiety around this symptom. It’s important for pregnant women experiencing extreme or persistent chills alongside other concerning signs (like fever or severe fatigue) to seek medical advice promptly since infections or other complications could be involved.
Maintaining open communication with healthcare providers about all symptoms ensures proper monitoring throughout pregnancy without undue stress over minor temperature fluctuations.
Treating & Managing Chills During Pregnancy Safely
If you’re wondering “Does Pregnancy Cause You To Be Cold?” chances are you want practical ways to stay cozy without harming your baby. Here are safe strategies:
- Dress warmly: Layer clothing including socks and gloves if needed indoors.
- Adequate nutrition: Focus on iron-rich foods like lean meats, spinach & legumes plus prenatal vitamins as prescribed.
- Mild exercise: Walking boosts circulation helping keep limbs warm naturally.
- Avoid sudden temperature changes: Gradually acclimate when going outdoors from heated environments.
- Stay hydrated: Proper fluid intake supports optimal blood flow.
- Mental relaxation: Stress reduction techniques like deep breathing prevent vasoconstriction caused by tension.
If anemia or thyroid issues are diagnosed by your doctor they will recommend appropriate supplements or medications tailored specifically for pregnancy safety profiles.

Frequently Asked Questions
Does pregnancy cause you to be cold due to hormonal changes?
Yes, pregnancy can cause you to feel cold because of hormonal fluctuations. Progesterone raises body temperature early on, but later shifts and fluctuations in hormones like estrogen and thyroid hormones can disrupt temperature regulation, sometimes leading to chills or cold sensations.
Does pregnancy cause you to be cold because of blood circulation changes?
Pregnancy increases blood volume by nearly 50%, which can affect circulation. Reduced blood flow to extremities may cause feelings of chilliness or cold hands and feet in some pregnant women, making it possible to feel cold despite overall increased body temperature.
Does pregnancy cause you to be cold if you have anemia?
Anemia during pregnancy, characterized by low red blood cell or hemoglobin levels, can reduce oxygen delivery throughout the body. This often results in cold hands and feet, making some pregnant women feel colder than usual as their bodies struggle to maintain warmth.
Does pregnancy cause you to be cold due to thyroid imbalances?
Thyroid hormones play a key role in metabolism and heat production. Pregnancy demands increased thyroid activity, but if hypothyroidism occurs, it can cause sensitivity to cold. This imbalance may make pregnant women feel unusually chilly during their pregnancy.
Does pregnancy cause you to be cold even though progesterone usually raises body temperature?
While progesterone generally increases basal body temperature early in pregnancy, fluctuations or dips in this hormone can lead to feeling cold or experiencing chills. Thus, despite the warming effect of progesterone, some women may still feel cold at times during pregnancy.
The Verdict – Does Pregnancy Cause You To Be Cold?
Feeling cold during pregnancy isn’t as common as feeling warm but it certainly happens due to a mix of hormonal shifts, circulatory changes, nutritional status, and metabolic factors unique to each woman’s experience. The exact answer depends heavily on individual physiology combined with lifestyle elements like diet and activity level.
