You’re sitting on the couch, maybe scrolling through your phone, and suddenly you feel it. A little thump-thump in your chest that feels just a bit too fast. Or maybe you glanced at your Apple Watch and saw a number that looked weirdly high compared to your husband’s. It’s a common moment of "Wait, is this okay?" honestly. Most of us just assume a heart is a heart, but biology doesn’t really work that way.
The truth is that normal heart rate in women is actually a moving target. It’s not a static number you just hit and stay at forever. Your heart is basically the most sensitive sensor in your body, reacting to your morning espresso, that stressful email from your boss, or where you are in your menstrual cycle.
What Scientists Actually Mean by "Normal"
When doctors talk about a resting heart rate, they’re looking at the number of times your heart beats per minute (BPM) while you are completely at rest. For most adult women, the standard "gold standard" range is between 60 and 100 beats per minute.
But here’s the kicker.

Research from the American College of Cardiology suggests that women often have slightly higher resting heart rates than men. Why? It's mostly down to size. Generally, women have smaller hearts than men. Because the heart is smaller, it has to beat a little more frequently to pump the same volume of blood throughout the body. It’s simple physics, really. If the pump is smaller, it works faster.
The Nuance of the 60 to 100 Range
If your heart rate is 62, you’re fine. If it’s 85, you’re also fine.
However, many fitness experts and cardiologists, including those at the Cleveland Clinic, argue that a resting heart rate on the lower end of that spectrum—say, in the 60s or 70s—is usually a sign of better cardiovascular efficiency. If you’re a marathon runner or someone who hits the Peloton four times a week, don’t be shocked if you see a number in the 40s or 50s. That’s called athletic bradycardia. It’s basically your heart being so strong that it doesn’t need to work hard to get the job done.
The Hormonal Rollercoaster You Didn't Ask For
You won't find this in many generic medical brochures, but your period actually changes your heart rate. It’s wild.
During the luteal phase (the time between ovulation and your period), your resting heart rate can jump by several beats per minute. This is largely thanks to progesterone. Progesterone raises your core body temperature, and when your temperature goes up, your heart rate follows suit. You might notice your "normal" heart rate is 65 BPM during the first two weeks of your cycle and then suddenly hits 72 BPM right before your period.

Pregnancy and the 20% Jump
Pregnancy is basically a nine-month endurance event. Your blood volume increases by about 40% to 50% to support the baby. To move all that extra liquid, your heart has to pick up the pace. It’s completely normal for a pregnant woman’s heart rate to increase by 10 to 20 beats per minute. If you were at 70 before, seeing 85 or 90 consistently is pretty standard.
Why Your Apple Watch Might Be Stressing You Out
Wearables are a double-edged sword. On one hand, data is great. On the other hand, it can turn us all into hypochondriacs.
Most wrist-based trackers use photoplethysmography (fancy word for using green lights to track blood flow). They are generally accurate for resting heart rate, but they can be finicky. If the band is loose, or if you have dark tattoos on your wrist, or if you’re just moving your arm a lot, the reading can be off.
Don't panic over a single "high" notification. Look at the trends. Is your average resting heart rate creeping up over a month? That’s worth a chat with a doctor. Is it just high because you had a glass of wine and watched a scary movie? Ignore it.
When Does a Normal Heart Rate in Women Become a Problem?
We need to talk about the red flags. While "normal" is broad, there are boundaries.
- Tachycardia: This is when your resting heart rate is consistently over 100 BPM. It can be caused by anemia (very common in women with heavy periods), thyroid issues, or just plain old dehydration.
- Bradycardia: If your heart rate is consistently under 60 and you are not an athlete, you might feel dizzy or fatigued. This means your heart isn't pushing enough oxygen to your brain.
The "Anxiety" Trap
Women are frequently told their physical symptoms are "just anxiety." It’s frustrating. While anxiety absolutely spikes your heart rate, a persistently high heart rate should never be dismissed without a basic workup. Conditions like POTS (Postural Orthostatic Tachycardia Syndrome) are significantly more common in women and involve the heart rate skyrocketing just from standing up.
If you feel like something is off, it probably is. Trust your gut over a chart.
Real World Factors That Mess With the Numbers
Life isn't a controlled lab environment. Several things will throw your numbers off today:
- Dehydration: When you’re low on fluids, your blood volume drops. Your heart beats faster to compensate. Drink a glass of water and check again in twenty minutes.
- Lack of Sleep: One bad night can jack up your resting heart rate by 5 to 10 beats the next day because your nervous system is stuck in "fight or flight" mode.
- Alcohol: That glass of rosé at dinner? It’s a vasodilator. It makes your heart work harder while you sleep. Most people see a significant spike in their overnight resting heart rate after even one drink.
- Caffeine: This one is obvious, but the half-life of caffeine is longer than you think. That 2 p.m. latte is still in your system at 8 p.m.
How to Get an Accurate Measurement
Stop checking it every five minutes. Seriously.
To find your true normal heart rate in women, measure it first thing in the morning. Before you get out of bed. Before you check your email. Before you even think about coffee. Put two fingers on your wrist (the radial pulse) or your neck (the carotid pulse). Count the beats for 30 seconds and multiply by two.
Do this for three days in a row and take the average. That is your baseline. Anything else you see during the day—while walking, talking, or working—is your "active" heart rate, which is a different beast entirely.
Taking Action: Your Next Steps
Knowing your number is just the start. If you’ve realized your heart rate is sitting a bit higher than the ideal range, or if you’re just looking to optimize your cardiovascular health, here is what actually works.
Prioritize Magnesium and Potassium
Women are frequently deficient in magnesium, which is crucial for electrical signaling in the heart. Eating more leafy greens, almonds, and avocados can help stabilize those electrical pulses. If you're constantly "thumping," check your electrolytes.
The Power of Zone 2 Cardio
You don't need to do high-intensity interval training (HIIT) every day. In fact, too much HIIT can sometimes keep your resting heart rate elevated by stressing the nervous system. Focus on "Zone 2" exercise—activity where you can still hold a conversation. A brisk 30-minute walk is often more effective for lowering your resting heart rate over time than a brutal 10-minute sprint.
Monitor Your Iron Levels
If you feel your heart racing and you also feel exhausted, ask your doctor for a ferritin test. Low iron is a massive driver of elevated heart rates in women. When you don't have enough iron, your blood can't carry oxygen efficiently, forcing your heart to work overtime to keep your organs happy.
Practice Vagus Nerve Stimulation
If your heart is racing due to stress, you can manually "brake" it. Try "box breathing": inhale for 4 seconds, hold for 4, exhale for 4, hold for 4. This stimulates the vagus nerve, which tells your heart to slow down immediately. It’s like a manual override for your nervous system.
Keep a simple log on your phone for two weeks. Note your morning heart rate, your cycle day, and how much sleep you got. This data is gold if you ever need to sit down with a cardiologist. It moves the conversation from "I feel like my heart is fast" to "Here is the data showing my heart rate correlates with my fatigue." That is how you get taken seriously in a medical setting.
