Hot flashes during pregnancy: causes, symptoms, and 6 effective remedies

Experiencing hot flashes during pregnancy can be both surprising and uncomfortable, particularly for first-time moms who may not expect these symptoms. While hot flashes are more commonly associated with menopause, hot flashes during pregnancy are actually quite common and can begin as early as the first trimester. In this comprehensive guide, we’ll dive into why hot flashes happen during pregnancy, when they typically start, and effective remedies for dealing with these uncomfortable symptoms.

What are hot flashes?

A hot flash is a sudden, intense sensation of warmth that generally affects the upper body, particularly the face, neck, and chest. The sensation often comes with visible redness or flushing and can cause sweating, heart palpitations, and sometimes even nausea. Hot flashes during pregnancy may include periods of hot and cold flashes where chills or cold sweats follow a sudden sensation of warmth. These temperature fluctuations can be especially frustrating during early pregnancy when hormones are already making the body work overtime to adapt. Hot flashes may cause:

• Sudden, intense warmth
• Red skin
• Intense sweat
• Chilled feeling as the hot flash goes away
• Increased heart rate

Are hot flashes a sign of pregnancy?

Yes, hot flashes can indeed be one of the early pregnancy symptoms. Many women report experiencing hot flashes and nausea early in pregnancy, particularly during the first trimester. Though not every woman will experience hot flashes as an early symptom, they are common enough to be considered a typical response to the body’s initial hormonal shifts. These symptoms are often caused by increased levels of progesterone and estrogen, which help prepare the body to support a growing fetus. Other early pregnancy symptoms include:

• Morning sickness
• Breast changes
• Digestion changes
• Loss of energy
• Mood swings
• Food cravings

When do you start feeling hot in pregnancy?

For most women, hot flashes during pregnancy can start as early as the first trimester when the body begins producing higher levels of estrogen and progesterone. Some women may experience hot flashes later on, particularly in the second or third trimester, as blood volume continues to increase and the body’s metabolism stays elevated. While hot flashes may vary in intensity and frequency, they tend to become more prominent during the third trimester as the body works to support the final stages of fetal development.

Why do hot flashes happen during pregnancy?

Hot flashes during pregnancy are caused by several physiological factors that combine to raise body temperature and trigger sensations of intense heat. Here’s a closer look at why they happen:

• Hormonal Changes: The sudden rise in progesterone and estrogen is one of the primary causes of hot flashes during pregnancy. These hormones influence the body’s temperature regulation, often making you feel warmer than usual.
• Increased Blood Flow: Pregnancy increases blood flow to support the placenta and developing baby, which can lead to a sensation of warmth or flushing. This increase is especially noticeable in the first trimester.
• Elevated Metabolic Rate: Your body is working harder than ever to support both you and your growing baby, causing your metabolism to stay elevated and generate more heat. This extra energy requirement is a key contributor to hot flashes during pregnancy.
• Sensitivity of the Hypothalamus: The hypothalamus, the brain’s temperature-regulating center, becomes more sensitive during pregnancy, making it easier for external and internal temperature fluctuations to cause hot flashes.

Are hot flashes common in early pregnancy?

Yes, hot flashes are common in early pregnancy. While they might catch some women off-guard, they are a normal part of the pregnancy experience for many. These early pregnancy hot flashes tend to lessen after the first trimester as the body gradually adjusts to the higher levels of hormones. However, some women may still experience hot flashes intermittently throughout the pregnancy, especially in the third trimester.

6 Remedies to help manage hot flashes during pregnancy

If you’re struggling with hot flashes during pregnancy, here are six tried-and-true remedies to keep you cool and comfortable:

Stay Hydrated

Drinking plenty of water throughout the day is essential to help regulate your body temperature. Dehydration can worsen hot flashes, so aim for at least 8-10 glasses of water daily.

Wear Breathable Clothing

Choose loose, light, and breathable clothing made from natural fibers like cotton or linen. These fabrics allow better air circulation, reducing the likelihood of hot flashes during pregnancy.

Use Fans and Keep Cool Air Flowing

Keep a portable or handheld fan nearby, especially at night, to stay cool. Try keeping windows open at home or using a fan to circulate air in the room to avoid feeling overheated.

 

Practice Relaxation Techniques

Sometimes, stress or anxiety can make hot flashes more intense. Try deep breathing exercises, meditation, or prenatal yoga to help keep your mind and body calm.

Stay Physically Active

Gentle, moderate physical activity can help keep your body’s systems balanced and may reduce the intensity of hot flashes over time. Walking, swimming, and other low-impact exercises are safe options during pregnancy.

Avoid Common Triggers

Caffeine, spicy foods, and hot showers can intensify hot flashes, so limiting or avoiding these triggers may be helpful. Try switching to herbal teas or cooler showers to reduce the impact of hot flashes during pregnancy.

The importance of monitoring fetal heart rate during pregnancy

Monitoring fetal heart rate is crucial for tracking your baby’s well-being throughout pregnancy. Regular checks provide essential information about the baby’s health, identifying potential issues early and allowing for prompt medical intervention if needed. During appointments, your healthcare provider typically uses a baby heartbeat doppler device to listen to the fetal heartbeat, but monitoring at home can provide extra peace of mind.

For expectant parents, using a home fetal Doppler device like the SonoHealth Fetal Doppler can be an excellent option for safely checking the baby’s heart rate between doctor visits. The SonoHealth Fetal Doppler is compact, user-friendly, and allows you to hear the baby’s heartbeat as early as 12 weeks. With a baby heartbeat doppler, parents can experience the reassurance of hearing their baby’s heart anytime, which can help reduce anxiety, especially in high-risk pregnancies.

Words from SonoHealth

In conclusion, hot flashes and nausea in early pregnancy are common symptoms driven by the body’s hormonal and physiological changes as it adapts to support a growing baby. Although hot flashes during pregnancy can be uncomfortable, they’re a normal response to elevated estrogen, increased blood flow, and heightened metabolism. Starting in the first trimester and possibly intensifying in later stages, these symptoms are manageable with simple remedies like staying hydrated, wearing breathable clothes, and avoiding common triggers. Understanding the causes and applying these strategies can help expectant mothers feel more comfortable, ensuring a smoother and healthier pregnancy journey.
