Quick take: Feeling unusually warm or experiencing occasional hot flashes is common in pregnancy and usually isn’t a cause for alarm. Your body’s hormone surge, especially progesterone, raises your core temperature a few degrees, and external heat can amplify the sensation. However, if you develop a true fever (temperature ≥ 100.4 °F/38 °C) or notice signs of overheating such as dizziness, rapid heartbeat, or confusion, you should contact your provider right away.

It’s 2 a.m., you’ve just rolled out of bed after a night of restless tossing, and a wave of heat washes over you. The sheets feel damp, your skin prickles, and you wonder if this is just another "pregnancy thing" or if something more serious is happening. You reach for your phone, Googling "why am I so hot during pregnancy," and the results leave you more confused than comforted. Sound familiar?

You’re not alone—millions of expectant parents report feeling hot, sweaty, or flushed at some point during pregnancy. This isn’t just in your head (or your thermostat). Your body is working overtime to support your growing baby, and that extra effort generates heat. But when does normal warmth cross into concerning territory? And how can you stay comfortable when even a gentle breeze feels like a sauna?

In this article, we’ll explain why pregnancy makes you feel hot, how your body’s temperature regulation changes, and what distinguishes a normal heat rise from a fever. We’ll share practical, science-backed ways to stay cool—whether you’re navigating a summer pregnancy or just trying to sleep through night sweats. We’ll also flag the warning signs that mean it’s time to call your provider, so you can enjoy your pregnancy with confidence and calm.

Why do I feel hot all the time during the first trimester?

During the first trimester, many women notice a persistent sense of warmth, especially in the evenings. This isn’t just your imagination—it’s your body’s way of adapting to the incredible changes happening inside you. The rapid rise in progesterone, a hormone that prepares the uterus for implantation and supports early fetal development, acts like a natural thermostat. It signals your hypothalamus (the brain’s temperature-control center) to raise your body’s set point by about 0.5 °F (0.3 °C). While this might not sound like much, even a small increase can make you feel uncomfortably warm, especially if you’re used to cooler temperatures.

But progesterone isn’t the only player. Your blood volume starts expanding almost immediately after conception, increasing by roughly 30% by the end of the first trimester. More blood circulating through your body means more warmth radiating to your skin, which can leave you feeling flushed or overheated even in a room that feels comfortable to others. This is why many women describe the first trimester as feeling like they’re running a low-grade fever—even though their actual temperature is within a normal range for pregnancy.

For some, this warmth is subtle—a gentle heat that lingers in the background. For others, it’s more pronounced, especially if they’re also dealing with morning sickness. Nausea can trigger stress hormones, which further amplify the sensation of heat. Dehydration, a common side effect of vomiting, can make the feeling worse, creating a cycle of discomfort that’s hard to break. If this sounds familiar, know that it’s temporary. Most women find their bodies adjust to the new baseline within a few weeks, and the intensity of the heat often lessens as they move into the second trimester.

Why am I sweaty during pregnancy?

Sweating is your body’s built-in cooling system, and during pregnancy, it’s working overtime. The same hormonal surge that raises your core temperature also stimulates your sweat glands. In the first trimester, the combination of higher progesterone, increased blood flow, and occasional nausea (which can trigger stress hormones) often leads to more frequent perspiration, especially at night. This isn’t just a nuisance—it’s a sign that your body is efficiently trying to regulate its temperature.

Night sweats can be particularly disruptive. You might wake up to find your pajamas damp and your sheets clammy, even if the room feels cool. This happens because your body’s temperature naturally fluctuates throughout the night, and pregnancy amplifies these shifts. If you’re struggling with night sweats, try keeping a small fan by your bed, using moisture-wicking sheets, or sleeping in lightweight, breathable pajamas. A cool shower before bed can also help lower your core temperature and set you up for a more restful night.

Pregnancy hot flashes and night sweats

Hot flashes—sudden spikes of heat followed by sweating—can happen at any stage of pregnancy, but they’re most common in the first and third trimesters. These flashes are usually brief, lasting anywhere from a few seconds to a few minutes, and they’re not a sign of illness. Instead, they’re your body’s way of releasing excess heat quickly. Night sweats are essentially hot flashes that occur while you’re sleeping, often disrupting rest. Both are usually harmless and tend to subside as your hormone levels stabilize later in pregnancy.

If you’re experiencing hot flashes, you might notice them triggered by seemingly small things—a warm room, a spicy meal, or even a moment of stress. This is because your body is more sensitive to temperature changes during pregnancy. The good news? There are simple ways to manage them. Dressing in layers, keeping a portable fan nearby, and staying hydrated can all help you feel more comfortable. If hot flashes are interfering with your sleep, try lowering the thermostat at night or using a cooling pillow to help regulate your temperature.

Is it normal to have hot flashes during pregnancy?

Yes, hot flashes are a recognized and common symptom of pregnancy. They’re most frequent in the first and third trimesters, when hormonal fluctuations are at their peak. According to the American College of Obstetricians and Gynecologists (ACOG), up to 70% of pregnant people report experiencing at least one hot flash during their pregnancy. While they can be uncomfortable, they’re usually harmless and don’t indicate any underlying health issues.

Hot flashes differ from fever in two key ways: they’re brief (usually lasting seconds to a few minutes), and they’re not accompanied by an elevated body temperature when measured with a thermometer. If you feel a sudden wave of heat that quickly resolves with a cool breeze or a glass of water, you’re likely dealing with a hot flash rather than an infection-related fever. That said, it’s always a good idea to keep a thermometer handy to double-check, especially if you’re feeling unwell.

For many women, hot flashes are more of an annoyance than a concern. They might happen a few times a day or just occasionally, and they often become less frequent as pregnancy progresses. However, if your hot flashes are accompanied by other symptoms—like dizziness, rapid heartbeat, or confusion—it’s important to talk to your provider. These could be signs of overheating, which requires medical attention.

What causes hot flashes in pregnancy?

Progesterone and estrogen are the primary hormones behind hot flashes in pregnancy. Progesterone, which surges in early pregnancy, raises your core temperature slightly, while estrogen influences blood vessel dilation. When your blood vessels expand, more blood flows to your skin’s surface, increasing heat loss and triggering a flash of warmth. This is why hot flashes often feel like a sudden rush of heat that starts in your chest or face and spreads outward.

Other factors can contribute to hot flashes, too. Stress, anxiety, and even certain foods (like spicy dishes or caffeine) can trigger them. Your body’s increased metabolic rate during pregnancy also generates more heat, which can make you more sensitive to temperature changes. If you’re prone to hot flashes, keeping a journal to track when they happen can help you identify patterns and avoid triggers.

Heat intolerance during pregnancy tips

  • Dress in layers: Lightweight, breathable fabrics like cotton or linen allow you to adjust your clothing as your temperature fluctuates. Avoid synthetic materials, which can trap heat and make you feel warmer.
  • Carry a portable fan or cool-mist spray: These can provide instant relief when a hot flash strikes, whether you’re at home or on the go.
  • Stay hydrated: Aim for at least 8–10 cups of water daily. Dehydration can make hot flashes worse, so keep a water bottle with you at all times.
  • Limit caffeine and spicy foods: Both can raise your body temperature and trigger hot flashes. If you’re sensitive to these, try cutting back to see if your symptoms improve.
  • Practice stress-reduction techniques: Deep breathing, meditation, or gentle yoga can help lower your stress levels, which may reduce the frequency of hot flashes.
  • Keep your environment cool: Use fans, air conditioning, or blackout curtains to maintain a comfortable temperature at home. If you’re outside, seek shade and avoid direct sunlight during peak hours.

How does pregnancy cause increased body temperature?

Pregnancy alters your body’s thermoregulation in several ways, all of which contribute to that persistent feeling of warmth. Beyond the hormonal effects of progesterone and estrogen, three key changes play a role:

  1. Basal metabolic rate (BMR) rises: Your body works harder to support the developing fetus, burning more calories and generating additional heat. This is why you might feel warmer even when you’re resting or sleeping.
  2. Blood volume expands: By the end of pregnancy, your blood volume increases by up to 50%. More circulating blood carries warmth throughout your body, especially to your skin’s surface, which can leave you feeling flushed or overheated.
  3. Respiratory changes: Progesterone stimulates deeper breathing, which increases oxygen intake but also raises your metabolic rate. This can lead to a slight increase in core temperature, particularly in the first trimester.

The combined effect of these changes is a modest, sustained rise in core temperature—often called “pregnancy-associated hyperthermia”—that is considered normal. The World Health Organization (WHO) notes that a maximum increase of 0.5 °F (0.3 °C) is typical and not harmful to the fetus. However, this small shift can feel much more significant, especially if you’re sensitive to temperature changes or living in a warm climate.

It’s also worth noting that your body’s ability to dissipate heat changes during pregnancy. Your sweat glands become more active, and your blood vessels dilate more easily, which helps release excess heat. However, these adaptations can also make you more susceptible to overheating if you’re exposed to high temperatures or humidity. This is why it’s important to take extra precautions during hot weather or when exercising.

Pregnancy and thermoregulation

Thermoregulation is your body’s ability to maintain a stable internal temperature, and pregnancy resets this system slightly. The hypothalamus, your brain’s temperature-control center, adjusts its set point upward to support fetal development. This process, sometimes called “physiologic fever,” is a protective adaptation that ensures optimal conditions for your baby’s growth. However, it can also leave you feeling warmer than usual, even in comfortable environments.

Your body’s thermoregulation is further influenced by your activity level, hydration status, and external temperature. For example, if you’re exercising or spending time in a hot environment, your body has to work harder to cool down. This is why pregnant women are more prone to overheating, especially in the third trimester when the baby’s metabolic demands are highest. To stay comfortable, it’s important to listen to your body and take steps to cool down when you feel too warm.

Difference between fever and pregnancy heat

FeatureNormal pregnancy heatFever (infection)
Typical temperature97.8 °F – 99.5 °F (36.5 °C – 37.5 °C)≥ 100.4 °F (38 °C)
DurationPersistent mild elevationSudden rise, often > 24 h
Associated symptomsWarmth, mild sweatingChills, aches, fatigue, possible rash
Response to antipyreticsUsually none neededOften reduced with acetaminophen (under provider guidance)
Underlying causeHormonal changes, increased blood volumeInfection, inflammation, or illness

When you measure your temperature with a reliable thermometer, a reading under 100.4 °F is generally considered normal for pregnancy, even if you feel hot. However, if your temperature meets or exceeds this threshold, it’s important to contact your provider. A fever can indicate an infection or other medical condition that requires treatment, so it’s always better to err on the side of caution.

What are the signs of overheating in pregnant women?

Overheating occurs when your body can’t dissipate heat efficiently, and it’s a serious concern during pregnancy. While a mild rise in temperature is normal, true overheating can pose risks to both you and your baby. The signs of overheating can be subtle at first, so it’s important to recognize them early and take action. Here’s what to watch for:

  • Dizziness or faintness: This can indicate that blood flow to your brain is compromised, which is a red flag for overheating. If you feel lightheaded, sit or lie down immediately and drink water.
  • Rapid heartbeat (tachycardia) or palpitations: Your heart works harder to pump blood to your skin when you’re overheated, which can lead to a racing pulse. If your heart rate feels unusually fast or irregular, seek a cooler environment and rest.
  • Excessive sweating with chills: While sweating is normal, excessive sweating followed by chills can signal heat exhaustion or heat stroke. This is a medical emergency and requires immediate attention.
  • Nausea, vomiting, or abdominal pain: These symptoms can accompany severe heat stress and may indicate dehydration or other complications. If you’re unable to keep fluids down, contact your provider.
  • Confusion or irritability: Overheating can affect your central nervous system, leading to mood changes or difficulty concentrating. If you feel unusually confused or agitated, it’s a sign to cool down and seek help.
  • Persistent headache that doesn’t improve with hydration: A headache that worsens despite drinking water can be a sign of dehydration or heat-related illness. Rest in a cool, dark room and monitor your symptoms.
  • Skin changes: Your skin may feel hot and dry to the touch, or you might develop a rash. In severe cases, your skin can become pale or clammy, which is a sign of heat exhaustion.

If you notice any of these symptoms, especially in combination, seek medical attention promptly. Overheating in pregnancy has been linked to rare but serious complications, such as neural tube defects in early gestation and reduced fetal growth later on, according to the CDC. To prevent overheating, avoid prolonged exposure to high temperatures, stay hydrated, and take frequent breaks in cool environments.

How to prevent overheating during pregnancy

Preventing overheating is all about staying cool and listening to your body. Here are some practical steps you can take to reduce your risk:

  • Stay hydrated: Drink water throughout the day, even if you’re not thirsty. Aim for at least 8–10 cups daily, and more if you’re active or spending time in hot weather. Electrolyte drinks can also help replenish minerals lost through sweating.
  • Avoid peak heat: Limit outdoor activities during the hottest parts of the day (usually between 10 a.m. and 4 p.m.). If you must be outside, seek shade and take frequent breaks in air-conditioned spaces.
  • Dress for the weather: Wear loose, lightweight clothing made of breathable fabrics like cotton or linen. Light colors reflect heat, while dark colors absorb it, so opt for whites, pastels, or neutrals when possible.
  • Use cooling accessories: A portable fan, cooling towel, or misting spray can provide instant relief when you’re feeling warm. Keep these handy in your bag or car for quick access.
  • Monitor your activity level: Avoid strenuous exercise in hot or humid conditions. If you’re working out, opt for low-impact activities like swimming, walking, or prenatal yoga, and take breaks as needed.
  • Keep your environment cool: Use fans, air conditioning, or blackout curtains to maintain a comfortable temperature at home. If you don’t have AC, consider visiting a public space like a library or mall to cool down.
  • Listen to your body: If you start to feel warm, take a break and cool down immediately. Don’t push through discomfort—your body is working hard enough already.

Can hot weather make pregnancy symptoms worse?

Absolutely. External temperature, humidity, and even wind can amplify the internal heat changes caused by pregnancy. High ambient heat forces your body to work harder to cool down, which can intensify hot flashes, night sweats, and overall discomfort. This is why many pregnant women feel worse during the summer months or in tropical climates.

Studies from the National Health Service (NHS) in the UK show that pregnant people living in regions with average summer highs above 85 °F (29 °C) report a 30% increase in heat-related complaints compared with those in cooler climates. Humidity compounds the effect because sweat evaporates more slowly, reducing your body’s primary cooling mechanism. This can leave you feeling sticky, sluggish, and irritable, even if you’re not doing anything strenuous.

Hot weather can also worsen other pregnancy symptoms, such as swelling, fatigue, and dizziness. For example, heat causes your blood vessels to dilate, which can lead to fluid retention and swelling in your hands, feet, and ankles. It can also lower your blood pressure, making you more prone to dizziness or fainting. If you’re already dealing with morning sickness or heartburn, the added heat can make these symptoms feel even more unbearable.

To minimize the impact of hot weather, try to stay indoors during peak heat hours, use fans or air conditioning to keep your environment cool, and wear lightweight, breathable clothing. If you’re outside, seek shade, wear a wide-brimmed hat, and apply sunscreen to protect your skin. Staying hydrated is also key—dehydration can worsen heat-related symptoms and increase your risk of overheating.

Safe ways to lower body temperature while pregnant

  • Take a cool shower or bath: A 10–15-minute soak in cool (not cold) water can help lower your core temperature and provide instant relief. Avoid hot baths or showers, as these can raise your body temperature further.
  • Apply a cold compress: Place a cool, damp cloth on your forehead, neck, or wrists. These areas have large blood vessels close to the skin’s surface, so cooling them can help regulate your body temperature.
  • Use a fan or air conditioner: Set your AC to a comfortable 72–74 °F (22–23 °C) and use fans to circulate air. If you don’t have AC, a portable fan can make a big difference in how you feel.
  • Wear loose, light-colored clothing: Tight clothing can trap heat and make you feel warmer. Opt for loose-fitting, breathable fabrics in light colors to reflect heat rather than absorb it.
  • Stay hydrated: Drink water throughout the day, and consider adding electrolyte-rich drinks or herbal teas (caffeine-free) to your routine. Avoid sugary or caffeinated beverages, as these can contribute to dehydration.
  • Eat cooling foods: Foods with high water content, like watermelon, cucumber, and citrus fruits, can help lower your body temperature. Cold soups, smoothies, and salads are also great options for hot days.
  • Limit outdoor activity: If possible, avoid spending time outside during the hottest parts of the day. If you must be outside, take frequent breaks in the shade and drink plenty of water.

Should I be concerned about fever vs normal pregnancy heat?

Distinguishing a fever from normal pregnancy-related warmth is essential because a fever can signal infection, inflammation, or other medical conditions that need treatment. While it’s normal to feel warmer during pregnancy, a true fever is a sign that your body is fighting something off—and that’s not something to ignore. Here’s how to tell the difference and what to do if you’re unsure:

  1. Check your temperature: Use a digital oral or forehead thermometer for the most accurate reading. Avoid ear or armpit thermometers, as these can be less reliable during pregnancy.
  2. If the reading is below 100.4 °F (38 °C): You’re likely experiencing normal pregnancy heat. Monitor how you feel and stay hydrated. If you’re still concerned, jot down any other symptoms (like chills, body aches, or fatigue) to discuss with your provider at your next appointment.
  3. If the reading is 100.4 °F (38 °C) or higher: Consider it a fever. Look for accompanying symptoms like chills, body aches, or urinary changes. A fever during pregnancy can be caused by infections like the flu, urinary tract infections (UTIs), or even foodborne illnesses, so it’s important to take it seriously.
  4. Take action: Contact your obstetrician, midwife, or primary care provider. They may recommend a safe antipyretic (like acetaminophen) to lower your fever and evaluate you for potential infections. Never take ibuprofen or aspirin during pregnancy unless specifically directed by your provider, as these can pose risks to your baby.

Remember, a mild fever in the first trimester can be particularly concerning because some infections (like rubella or cytomegalovirus) are linked to birth defects. Even if your fever is low-grade, it’s always safer to get it checked out. Your provider can perform tests to rule out infections and recommend the best course of action to keep you and your baby safe.

When to worry about a fever in pregnancy

While a low-grade fever (100.4–101 °F) can sometimes be managed at home with rest and fluids, there are situations where a fever warrants immediate medical attention. Here’s when to call your provider right away:

  • Fever ≥ 102 °F (38.9 °C): A high fever can be dangerous for both you and your baby, especially if it lasts more than a few hours. Seek medical care immediately to rule out serious infections.
  • Fever lasting more than 24 hours: A persistent fever, even if it’s low-grade, can indicate an underlying infection that needs treatment. Don’t wait to see if it improves on its own—contact your provider for guidance.
  • Fever with other symptoms: If your fever is accompanied by chills, body aches, fatigue, or a rash, it could be a sign of a viral or bacterial infection. Other red flags include urinary symptoms (like pain or burning), abdominal pain, or vaginal discharge.
  • Fever in the first trimester: While any fever during pregnancy should be evaluated, fevers in the first trimester are particularly concerning because they can increase the risk of neural tube defects or other complications. If you develop a fever during this time, contact your provider as soon as possible.
  • Fever that doesn’t respond to acetaminophen: If you’ve taken acetaminophen (as directed by your provider) and your fever hasn’t improved within a few hours, it’s a sign that you need medical evaluation.

If you’re ever unsure whether your fever is serious, it’s always better to call your provider. They can help you determine whether you need to be seen in person or if you can manage your symptoms at home. Trust your instincts—if something doesn’t feel right, don’t hesitate to reach out.

How to stay cool during pregnancy

Keeping your environment and habits cool can make a huge difference in how you feel day-to-day. The good news? Small changes can add up to big relief. Below are evidence-based tips that blend comfort with safety, so you can stay cool without sacrificing your well-being or your baby’s.

Take advantage of breezy outdoor spaces—fresh air and shade can lower your core temperature.
  • Hydration first: Aim for 2–3 liters of fluids daily. Water is your best bet, but coconut water, electrolyte drinks, and caffeine-free herbal teas can also help replenish lost minerals. Keep a water bottle with you at all times, and set reminders to drink if you tend to forget.
  • Cool your skin: Keep a small bottle of chilled water in the fridge and splash it on your wrists, neck, and face. These pulse points have large blood vessels close to the skin’s surface, so cooling them can help lower your core temperature quickly. A damp washcloth or cooling towel can also provide relief.
  • Adjust your diet: Favor cold or room-temperature foods like salads, yogurt, and fresh fruit. These require less energy to digest, which means your body generates less heat. Avoid heavy, hot meals during heat waves, as they can make you feel sluggish and warmer. If you’re craving something warm, opt for lighter options like broth-based soups or steamed vegetables.
  • Mind your footwear: Open-toed shoes and breathable socks (like cotton or moisture-wicking materials) can help reduce foot heat and swelling. Avoid tight shoes or synthetic materials, which can trap heat and make your feet feel even warmer.
  • Schedule activities wisely: Exercise in the early morning or late evening when temperatures are lower. If you’re working out indoors, choose a well-ventilated space with fans or air conditioning. Keep your workouts moderate—now isn’t the time to push yourself to the limit. Listen to your body and take breaks as needed.
  • Control indoor climate: Use fans, keep blinds closed during peak sun hours, and consider a portable air conditioner if your home gets too warm. If you don’t have AC, try sleeping with a damp sheet or using a fan to circulate air. A cool mist humidifier can also help, especially if you’re dealing with dry heat.
  • Optimize your sleep environment: Night sweats can make it hard to get a good night’s rest. To combat this, use moisture-wicking sheets (like bamboo or cotton), sleep in lightweight pajamas, and keep a fan by your bed. A cooling pillow or gel pad can also help regulate your temperature while you sleep.
  • Take cool showers or baths: A 10–15-minute soak in cool water can lower your core temperature and provide instant relief. Avoid hot baths or showers, as these can raise your body temperature further. If you’re not a fan of showers, try soaking your feet in cool water for a few minutes—it’s surprisingly refreshing.
  • Use cooling products: Products like cooling sprays, gel packs, or even a damp towel can provide quick relief when you’re feeling overheated. Keep these in your bag or car for easy access when you’re on the go.
  • Stay mindful of your surroundings: If you’re outside, seek shade and avoid direct sunlight during peak hours. Wear a wide-brimmed hat and sunglasses to protect your skin and eyes. If you’re indoors, avoid rooms that trap heat, like kitchens or laundry rooms, especially during the hottest parts of the day.

These habits not only help you feel cooler but also support healthy blood circulation and reduce the risk of dehydration. The key is to find what works best for you and make it a part of your daily routine. Small, consistent efforts can make a big difference in how you feel throughout your pregnancy.

How does pregnancy affect your body’s response to heat?

Pregnancy changes how your body responds to heat in several ways, making you more sensitive to temperature changes and more prone to overheating. Understanding these changes can help you stay safe and comfortable, especially during hot weather or physical activity. Here’s what’s happening inside your body:

First, your metabolic rate increases to support your growing baby. This means your body generates more heat, even when you’re at rest. In fact, your metabolic rate can increase by up to 20% during pregnancy, which is why you might feel warmer than usual even in mild temperatures. This extra heat production is normal, but it can make you more susceptible to overheating if you’re not careful.

Second, your blood vessels dilate more easily during pregnancy. This is a natural response to the increased blood volume and hormonal changes, but it also means your body releases heat more quickly. While this helps regulate your temperature, it can also make you feel flushed or overheated, especially in warm environments. This is why many pregnant women experience hot flashes or night sweats—their bodies are working harder to dissipate heat.

Third, your sweat glands become more active. Sweating is your body’s primary way of cooling down, and during pregnancy, your sweat glands work overtime to help regulate your temperature. This is why you might find yourself sweating more than usual, even when you’re not exerting yourself. While sweating is normal, it can also lead to dehydration if you’re not replenishing lost fluids, so it’s important to drink plenty of water throughout the day.

Finally, your body’s ability to conserve heat changes. Normally, your body can constrict blood vessels to conserve heat in cold environments. However, during pregnancy, this response is blunted, which means you might feel colder than usual in cool temperatures. This is why some women experience chills or shivering alongside hot flashes—it’s your body’s way of trying to balance its temperature.

These changes are all part of your body’s adaptation to pregnancy, but they can also make you more vulnerable to heat-related illnesses. To stay safe, it’s important to take extra precautions during hot weather, avoid strenuous activity in high temperatures, and listen to your body’s signals. If you start to feel too warm, take a break, cool down, and hydrate.

Tips for managing heat sensitivity during pregnancy

If you’re feeling more sensitive to heat during pregnancy, you’re not alone. Here are some practical tips to help you manage this symptom and stay comfortable:

  • Dress in layers: Wearing layers allows you to adjust your clothing as your temperature fluctuates. Opt for lightweight, breathable fabrics like cotton or linen, and avoid synthetic materials that trap heat.
  • Stay hydrated: Drink water throughout the day, even if you’re not thirsty. Dehydration can worsen heat sensitivity and increase your risk of overheating. Aim for at least 8–10 cups of water daily, and more if you’re active or spending time in hot weather.
  • Use cooling accessories: A portable fan, cooling towel, or misting spray can provide instant relief when you’re feeling warm. Keep these handy in your bag or car for quick access.
  • Avoid peak heat: Limit outdoor activities during the hottest parts of the day (usually between 10 a.m. and 4 p.m.). If you must be outside, seek shade and take frequent breaks in air-conditioned spaces.
  • Monitor your activity level: Avoid strenuous exercise in hot or humid conditions. If you’re working out, opt for low-impact activities like swimming, walking, or prenatal yoga, and take breaks as needed.

  • Take cool showers or baths: A 10–15-minute soak in cool water can lower your core temperature and provide instant relief. Avoid hot baths or showers, as these can raise your body temperature further.
  • Practice stress-reduction techniques: Stress and anxiety can amplify heat sensitivity, so finding ways to relax can help. Try deep breathing, meditation, or gentle yoga to lower your stress levels and stay cool.

Can feeling hot during pregnancy affect my baby?

One of the most common concerns among pregnant women is whether feeling hot can harm their baby. The good news is that a mild increase in your core temperature—like the 0.5 °F (0.3 °C) rise caused by hormonal changes—is not harmful to your baby. Your body is designed to protect your little one, and the placenta plays a key role in regulating their temperature. However, there are situations where overheating or a high fever can pose risks, so it’s important to understand the difference.

First, let’s talk about normal pregnancy heat. The slight increase in your core temperature during pregnancy is a natural part of your body’s adaptation to support your baby’s
