You're sitting on the couch, maybe scrolling through your phone after a long day, and you suddenly feel it. That little thump-thump in your chest. It feels a bit fast, doesn't it? Or maybe you just glanced at your Apple Watch or Fitbit and saw a number that looked... off.
Honestly, most of us don't even think about our hearts until they do something weird. But here’s the thing: a normal heart beat rate for women isn't just a single, static number that stays the same from puberty through menopause. It’s a moving target. It shifts when you’re stressed, it definitely shifts when you’re pregnant, and it changes as your hormones do their monthly dance.
If you’ve ever Googled "what is a good pulse" and seen the standard "60 to 100 beats per minute" range, you’re only getting half the story. That range was largely based on data from men. Women’s hearts are literally smaller, their physiology is different, and their "normal" can look quite different from their husband's or brother's.
The Reality of the Numbers: Why 72 BPM Isn't the Only Answer
For decades, the medical community pointed to 72 beats per minute (BPM) as the gold standard. It’s a nice, round number. It’s also kinda misleading.
The American Heart Association still maintains that a normal heart beat rate for women (and men) at rest is anywhere between 60 and 100 BPM. But "normal" and "optimal" are two very different things. A woman who is highly athletic might have a resting heart rate in the 40s or 50s. Meanwhile, someone dealing with chronic anxiety or a thyroid issue might hover at 95 and still be told they are technically in the "normal" range, even if they feel like their heart is racing.
Recent large-scale studies, including data analyzed from wearable tech companies like Fitbit and Oura, suggest that women actually tend to have slightly higher resting heart rates than men. We’re talking about 2 to 7 beats per minute faster on average. Why? Because women’s hearts are generally smaller in physical size. Since the pump is smaller, it has to beat a little more frequently to move the same volume of blood throughout the body.
It’s just physics.
Hormones: The Invisible Pulse Driver
This is where it gets interesting—and where most general medical advice fails women. Your cycle matters.

During the follicular phase (the time from the first day of your period until ovulation), your resting heart rate is usually at its lowest. But once you hit the luteal phase (after ovulation), your progesterone levels spike. Progesterone is thermogenic—it raises your body temperature. When your temp goes up, your heart rate follows. You might notice your resting pulse climb by 5 to 10 beats per minute in the week before your period starts.
If you didn’t know this, you might think you’re getting sick or becoming "unfit." You’re not. You’re just a person with fluctuating hormones.
Pregnancy and the Massive Cardiac Shift
If you want to talk about a radical change in a normal heart beat rate for women, look at pregnancy.
By the time a woman reaches her third trimester, her blood volume has increased by nearly 50%. That is an incredible amount of extra fluid for one muscle to move. To keep up with the demand of nourishing a fetus and keeping the mother stable, the heart rate naturally climbs.
It’s not uncommon for a pregnant woman’s resting heart rate to increase by 10, 15, or even 20 beats per minute. A woman who started her pregnancy with a resting pulse of 70 might find herself sitting at 90 BPM while just reading a book. In any other context, that might be a cause for concern, but in the context of gestation, it’s often just the body doing its job.
However, there’s a limit. If that rate stays consistently above 100 (tachycardia) while resting, or if it’s accompanied by palpitations or dizziness, doctors start looking for things like gestational anemia or even preeclampsia.
When the Numbers Get Concerning

If your heart rate is consistently over 100 BPM while you are sitting still and calm, that’s technically tachycardia. It can be caused by a lot of things that aren't "heart disease." Dehydration is a massive culprit. When you're low on fluids, your blood volume drops, and your heart has to work harder to maintain blood pressure.
Other common "silent" drivers of a high heart rate in women:
- Iron Deficiency Anemia: This is huge for women of childbearing age. Fewer red blood cells mean less oxygen transport, so the heart beats faster to compensate.
- Thyroid Overactivity: An overactive thyroid (hyperthyroidism) is like putting your body's engine into overdrive.
- Caffeine and Supplements: That "fat burner" supplement or the third espresso? Yeah, those will do it.
- Perimenopause: The hormonal chaos leading up to menopause often causes heart palpitations and temporary spikes in heart rate.
On the flip side, we have bradycardia—a heart rate below 60 BPM. While this is often a sign of a very "fit" heart, it can also be a sign of electrical issues in the heart or an underactive thyroid (hypothyroidism). If you’re at 55 BPM but you feel dizzy, fatigued, or like you're about to faint, that "athletic" pulse isn't a badge of honor; it's a medical red flag.
How to Actually Measure Your Resting Heart Rate (Properly)
Most people check their pulse wrong. They check it after they’ve walked up the stairs, or right after a stressful work call, or while they’re standing up.
To find your true normal heart beat rate for women, you need to be clinical about it.
- The best time is the very moment you wake up, before you even sit up in bed.
- Don't use your thumb—it has its own pulse. Use your index and middle fingers on your wrist (radial pulse) or the side of your neck (carotid pulse).
- Count for a full 60 seconds. Don't do the "count for 15 and multiply by four" trick. It's less accurate, especially if you have a slight arrhythmia.
Wearables are great for trends, but they aren't infallible. If your watch tells you your heart rate is 140 while you're washing dishes, take a manual pulse before you panic. Sensors can glitch, especially if the band is loose or you're moving your arm a certain way.
Stress, Anxiety, and the "Female" Heart
We have to talk about the mental-cardiac connection. Women are statistically more likely to be diagnosed with anxiety disorders, and anxiety is a primary driver of heart rate variability.

When you're stressed, your sympathetic nervous system kicks in—the "fight or flight" response. Adrenaline and cortisol flood your system. Your heart rate jumps. This is normal in short bursts. But chronic stress keeps your heart rate elevated, which can lead to wear and tear over time.
It’s also important to note that heart attack symptoms in women are famously different than in men. While men often get the "Hollywood" chest pain, women might just feel an unusually fast heart rate, extreme fatigue, or shortness of breath. If your heart rate feels "wrong" and it’s paired with nausea or jaw pain, don’t ignore it.
Moving Toward Actionable Health
Knowing your numbers is the first step, but what do you do with them?
If you find that your resting heart rate is creeping up over months, it's a signal. It might not be a signal of a failing heart, but a signal of a lifestyle that needs a tweak. Increased cardiovascular exercise—specifically Zone 2 training where you can still hold a conversation—is the best way to strengthen the heart muscle and lower your resting rate over time.
Better sleep, more magnesium-rich foods (like spinach and almonds), and staying hydrated also play massive roles in stabilizing those numbers.
Your Next Steps for Cardiac Health
Stop comparing your pulse to a generic chart on the wall of a doctor's office. Start tracking your own baseline.
- Track for a Month: Use a journal or an app to record your waking heart rate every day for one full menstrual cycle. Note which days you’re on your period and which days you’re stressed.
- Check Your Ferritin Levels: If your heart rate is consistently high and you feel tired, ask your doctor for a full iron panel, not just a standard CBC.
- Watch the "Hidden" Stimulants: Audit your intake of "pre-workout" drinks, sodas, and even certain decongestants, which can spike your pulse.
- Prioritize Vagus Nerve Toning: Simple breathwork (inhaling for 4, exhaling for 6) can physically force your heart rate to drop by activating the parasympathetic nervous system.
Your heart rate is a vital sign for a reason. It’s a real-time report card of how your body is handling the world. Treat it like a piece of data, not a reason for anxiety, and use it to make informed decisions about your rest and activity.
