Heart Rate 101: What’s Normal, What’s Not, and How to Improve It

Why Monitoring Your Heart Rate Matters

😰 Your heart rate isn’t just a number.
When it’s consistently too high or too low, it may be an early warning sign from your body.
Because your heart beats non-stop every day, your heart rate is one of the most immediate indicators of your overall health.

While many people think of blood pressure or cholesterol when it comes to heart health,
heart rate is just as important.
In particular, your resting heart rate (RHR) reflects your cardiovascular fitness, stress levels, and how efficiently your heart is functioning.

🔎 What’s Considered a Healthy Heart Rate?

For most adults, a normal resting heart rate ranges from 60 to 100 beats per minute (bpm).
For athletes or very fit individuals, it may drop to around 50 bpm, which is typically a sign of a well-trained, efficient heart—not a health risk.

🏃‍♀️ Target Heart Rate for Exercise

To boost cardiovascular health, experts recommend exercising at 50–85% of your maximum heart rate.
You can estimate your maximum heart rate with this simple formula:

220 - your age

For example, if you're 40 years old, your max heart rate is around 180 bpm,
so your target range during exercise would be 90 to 153 bpm.

📊 What Affects Your Heart Rate?

Your heart rate changes throughout the day. Common influencing factors include:

• Physical activity – Even climbing stairs can cause a spike

• Sleep quality – Poor sleep may increase resting heart rate

• Stress & anxiety – Keep your heart on high alert

• Diet – Caffeine, alcohol, and sugar can raise your heart rate

• Medications – Some increase your heart rate, while others lower it

🤖 Making the Most of Health Data

Today, many people use smartwatches and health apps to log their heart rate, blood pressure, sleep, and more.
This data isn't just for tracking—it can provide valuable insight into patterns and changes in your body.

Looking at how your heart rate fluctuates alongside stress and sleep,
you may uncover clues that help answer questions like,
“Why am I feeling lightheaded lately?”

Some apps go a step further by offering personalized guidance.
For example, a tool like Ask Dr. AI may use your recorded health data
to provide tailored information based on symptoms or trends you’ve been tracking.
