Feeling cold can be an unexpected sensation during pregnancy, especially in early stages. While many associate pregnancy with feeling warmer, experiencing a chill can also occur. This sensation is not a universal or definitive indicator of pregnancy, but it can be part of the complex physiological adjustments the body undergoes. Internal factors contribute to these temperature shifts as the body adapts to its new state.
Understanding Why You Might Feel Cold
Hormonal fluctuations are a primary reason for experiencing cold sensations during pregnancy. The significant rise in progesterone, a hormone crucial for maintaining pregnancy, influences the body’s thermoregulation. While progesterone generally elevates basal body temperature, its fluctuations and relaxing effect on blood vessels may cause some to feel colder, particularly in extremities like hands and feet.
Changes in metabolic rate also contribute to temperature variations. Pregnancy necessitates increased metabolic effort to support the developing fetus, typically generating more heat. However, heightened metabolic activity can sometimes lead to fluctuations in body temperature regulation, causing moments where a pregnant individual might feel colder, especially when less active.
Increased blood volume and its redistribution throughout the body can further influence temperature perception. As pregnancy progresses, blood flow is increasingly directed to the uterus and other vital organs, which can temporarily reduce circulation to the hands and feet. This shift can lead to coldness in these areas, even if core body temperature remains stable or slightly elevated.
Iron-deficiency anemia is another common condition during pregnancy that can cause cold intolerance. Expanded blood volume during gestation increases the demand for iron. If this demand is not met, the body’s ability to transport oxygen efficiently can be compromised, resulting in symptoms such as fatigue, pallor, and a persistent feeling of cold.
Thyroid function can also play a role in regulating body temperature. Hypothyroidism, an underactive thyroid gland, can lead to symptoms like cold sensitivity, fatigue, and constipation. This condition can develop or worsen during pregnancy, and because thyroid hormones are essential for metabolism and temperature control, an imbalance can contribute to feeling cold.
Other Common Early Indicators
While feeling cold can be a subtle sign, a missed period remains one of the most recognized early indicators of pregnancy for those with a regular menstrual cycle. This absence often prompts further investigation.
Many also experience nausea and vomiting, commonly called “morning sickness,” though it can occur at any time. This symptom typically emerges between four and six weeks of pregnancy and can significantly impact daily life.
Overwhelming fatigue is another prevalent early symptom, often setting in during the first trimester. Hormonal shifts contribute to this tiredness, as the body expends considerable energy supporting initial fetal development.
Changes in breast sensation, such as tenderness, swelling, or tingling, are common. These changes can be similar to pre-menstrual breast soreness but are often more pronounced due to increased hormone levels preparing breasts for lactation.
Frequent urination often begins early in pregnancy due to increased blood volume and kidneys processing extra fluid. This leads to more trips to the bathroom, even at night.
Shifts in appetite, including food cravings or aversions, are frequently reported. Pregnant individuals may desire certain foods intensely while disliking others they previously enjoyed, sometimes with a metallic taste in the mouth.
When to Seek Medical Advice
If coldness is severe, persistent, or accompanied by other concerning symptoms, seek medical advice. These might include extreme fatigue, dizziness, significant pallor, or shortness of breath. A fever, especially with chills, should also prompt immediate medical attention, as it could indicate an underlying infection.
Professional confirmation is advisable if pregnancy is suspected based on multiple early indicators, including feeling cold. A healthcare provider can conduct tests to confirm pregnancy and initiate prenatal care, crucial for monitoring both maternal and fetal health.
It is important to rule out or manage any underlying conditions contributing to cold sensitivity. Conditions such as iron-deficiency anemia or thyroid imbalances require proper medical diagnosis and treatment to ensure the well-being of the pregnant individual and developing baby.
A general health check-up is always recommended for any persistent or unusual symptoms experienced during pregnancy or when trying to conceive. Open communication with a healthcare provider ensures concerns are addressed and appropriate care is received throughout the pregnancy journey.
