Why do You Feel Cold During Pregnancy?


Feeling warm is absolutely normal when it comes down to getting pregnant or expecting a baby to come soon. This is due to the presence of hormones at work and all the blood flow that delivers the nutrients to your baby. This causes your body to work its way to cool it down as much as possible. But what happens when your body goes overkill with the cooling process?


That’s the point where some pregnant women can feel cold or extremely chilly during their pregnancy, which, in most cases, is normal. But what if the chills aren’t normal? How can you tell if it’s really harmless to you and your baby? In this article, we’ll give you some of the most common reasons as to why you could be feeling cold when you are on your different trimesters of pregnancy and if the cause is normal or not.


Common Reasons for Pregnancy Cold Temperature

Before we go to the common reasons, first, here’s a little disclaimer: having a fever or cold is far different from the chills that pregnant women can have. If you experience coughing, sore throat, nausea, fatigue and a body temperature that’s much higher than 37.5 degrees C (99.5 degrees F), it may be a cold or fever/flu.


With that said, here are some common reasons for getting cold during pregnancy, so that you’ll know when you should be alarmed (or not alarmed at all):

When Coldness is Normal and Not Too Alarming:


  1. Slight lack of nutrients

When you are taking less than normal vitamins, carbohydrates, minerals, and proteins, chances are, you may feel a little chilly. Being a pregnant woman requires you to take enough nutrients for you and your baby’s nourishment, and you can feel a little cold without it. Can you imagine a coal or gas furnace without ignition? That’s a good analogy to this – you’ll need the spark of nutrients in order to fuel your energy and heat up a bit.


  1. Basal body temperature

Because of the production of progesterone and estrogen, you may start to feel some odd changes with your body temperature within 16 weeks of your pregnancy. This is normal because of the hormonal changes, so it’s nothing to worry about. This coldness can usually dissipate after 16 weeks when your body doesn’t have to work as hard as before in regulating the hormone changes.


  1. Morning Sickness

Yep, morning sickness is a common thing with pregnant women, so it’s nothing too alarming at most. This morning sickness is usually resulting in loss of appetite, which can cause you to cut down on eating and therefore, feel chilly due to being under hydrated and having little food in your system.


  1. Irregular blood flow

Blood circulation is highly important for both you and your baby. The problem with pregnancy is that you need a lot of blood flow in order to nourish your little one. If you have irregular blood flow or circulation or if you experience a lack of blood health, you may feel a little chilly as well due to insufficient nutrients. This is also due to the pregnancy and stages that can change throughout the trimesters as your baby develops or matures.


When Coldness is Not Normal and Requires Medical Experts:

  1. Hypothyroidism

When you feel absolutely cold all the time in your pregnancy stages, chances are, a thyroid problem known as hypothyroidism can be the cause. This condition is kind of hereditary at most points and it is caused by an underactive thyroid due to having low amino acids.


It can ruin not just your metabolism and energy, but can also affect your baby’s development. Some studies show that it can be linked to a miscarriage or a developmental delay, so it’s best to consult it with your OB.


  1. Anemia

While poor blood flow is not too alarming, when it reaches the level of anemia, it can be serious. You will need to take some iron supplements like pills or natural food, as well as probiotics for better digestion and metabolism regulation. Serious anemia can also be characterized by nausea or lethargy so this can be a concern, especially if you are on your later trimester since it can be a threat to your baby’s oxygen supply.


  1. Sudden weight loss

Sure, losing weight is important in terms of managing your overall health, but when it comes down to the point when your overall weight is too little to support your baby, it can make your body temperature go down and cause you to have lack of energy. While many pregnant women have the problem of weight gain, some can also have the problem of weight loss. It’s best to consult your OB or nutritionist for more details about this since not all people have the same metabolism rate.


  1. Urinary Tract Infection

A common infection that women can have during their pregnancy would be UTI, but other infections can also occur, which can give them chills other than nausea. You should treat these infections as soon as possible to keep your baby safe from harm since infections can attack a baby’s developmental cycle.


What Can I Do to Stay Warm?

Here are the things you should do in order to stay warm during pregnancy:


  1. Drink lots of soups or hot liquids to warm up
  2. Use natural heating, indoor heating, and other temperature adjustments
  3. Wear clothes to make you feel warmer, such as socks and thick jackets
  4. Maintain a healthy diet to avoid a nutrient loss as well as anemia
  5. Get enough sleep to make sure you’re not going to run into low blood state



As a whole, pregnancy coldness can be alarming at first, but once you figure out or if your practitioner diagnoses your coldness for another condition then there’s nothing to worry about. We hope that this informative article can help you to know why you feel cold during pregnancy and what you can do about it to keep you warm again!
