A normal resting heart rate for a woman falls between 60 and 100 beats per minute (BPM). Most healthy adult women sit somewhere in the middle of that range, typically between 65 and 85 BPM. That said, the number on your wrist or fitness tracker can shift meaningfully depending on your fitness level, where you are in your menstrual cycle, whether you’re pregnant, and even the time of day you check it.
Why Women’s Heart Rates Tend to Run Higher
Women generally have slightly higher resting heart rates than men. The reason is structural: a woman’s heart is, on average, physically smaller. A smaller heart holds less blood per beat, so it needs to beat more frequently to pump the same volume of blood throughout the body. The difference is modest, usually only a few beats per minute, but it’s consistent enough to show up across large population studies.
Highly fit women can have resting heart rates well below the typical range. Athletes sometimes clock resting rates closer to 40 BPM because regular cardiovascular training enlarges the heart’s pumping chambers, allowing more blood per beat. A low resting heart rate in someone who exercises regularly is a sign of cardiovascular efficiency, not a problem.
How Your Menstrual Cycle Affects Your Heart Rate
Your resting heart rate isn’t fixed throughout the month. Hormonal shifts during the menstrual cycle create a predictable pattern: your heart rate tends to rise slightly around ovulation and stays elevated during the week that follows, then dips during your period and the week after. These fluctuations are normal and usually stay within a few beats per minute, but they can be noticeable if you’re tracking daily.
This is worth knowing because a jump of 3 to 5 BPM mid-cycle doesn’t necessarily signal a health change. If you’re using a wearable to monitor trends, comparing the same phase of your cycle month to month gives you a more accurate picture than comparing random days.
Heart Rate Changes During Pregnancy
Pregnancy pushes your resting heart rate up significantly. The increase starts early in the first trimester and continues climbing, peaking in the third trimester. Research from the Harvard Apple Women’s Health Study found that the median resting heart rate before pregnancy was about 65.5 BPM, and it peaked around 77 BPM in the third trimester, roughly 8 weeks before delivery. That’s a 20% to 25% increase, or about 10 to 20 extra beats per minute by the end of pregnancy.
This rise happens because your blood volume increases dramatically during pregnancy (by about 50%), and your heart has to work harder to circulate that extra blood to the placenta and growing baby. A resting rate in the 80s or even low 90s during late pregnancy is common and expected.
How to Measure Your Resting Heart Rate Accurately
To get a reliable reading, check your heart rate first thing in the morning before getting out of bed. You should be lying or sitting still, not right after an alarm jolts you awake. Place two fingers (your index and middle finger) on the inside of your wrist, just below the base of your thumb, and count the beats for 30 seconds. Multiply by two to get your BPM.
Avoid measuring after caffeine, exercise, or a stressful moment, since all of these temporarily raise your rate. If you’re using a fitness tracker, the morning reading tends to be the most consistent one to watch over time. Single readings matter less than your trend over weeks and months.
When a High or Low Rate Matters
A resting heart rate consistently above 100 BPM is considered tachycardia. On its own, a slightly elevated number isn’t always cause for concern, as dehydration, stress, poor sleep, or too much caffeine can all push you over that threshold temporarily. But a persistently high rate, especially paired with symptoms like palpitations, chest pain, lightheadedness, shortness of breath, or fainting, deserves medical attention.
On the low end, the threshold has shifted in recent years. While 60 BPM was traditionally the cutoff for bradycardia, updated clinical guidelines from the American College of Cardiology now use 50 BPM as the more meaningful lower boundary, reflecting population data showing that many healthy people naturally sit in the 50s. If you’re not a trained athlete and your resting rate regularly falls below 60, it’s worth mentioning to your doctor. Below 50 in a non-athlete is more clearly unusual.
Factors That Shift Your Baseline
Beyond fitness, hormones, and pregnancy, several everyday factors influence where your resting heart rate lands:
- Age: Resting heart rate doesn’t change dramatically with age in healthy adults, but cardiovascular fitness tends to decline over time, which can nudge the rate upward.
- Medications: Beta-blockers lower heart rate, while some asthma inhalers and decongestants raise it.
- Body temperature: A fever can increase your heart rate by about 10 BPM for every degree Fahrenheit above normal.
- Stress and sleep: Chronic stress and sleep deprivation both keep your resting rate elevated. Improving sleep quality is one of the most reliable ways to bring a creeping heart rate back down.
- Hydration: When you’re dehydrated, your blood volume drops, and your heart compensates by beating faster.
If you notice your resting heart rate trending upward over several weeks without an obvious explanation, it can be an early signal of overtraining, illness, or increased stress before you feel other symptoms. That’s one of the most practical uses of tracking your number over time: catching changes early, rather than fixating on any single reading.
