Should I be worried if my resting heart rate is 100?

What is a normal resting heart rate?

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For athletes, a normal resting pulse may be closer to 40 beats per minute, while for less active individuals, a normal rate may be closer to 100 beats per minute.

The most commonly recommended normal resting heart rate is between 60 and 80 beats per minute. However, a heart rate up to 100 beats per minute is still considered in the normal range. If your resting heart rate is consistently above 100 beats per minute, it would be considered high and you may want to consult your doctor.

Average resting heart rate ranges by age:

Age Normal Resting Heart Rate Range
Newborns (birth to 3 months) 70 to 190 beats per minute
Infants (3 months to 2 years) 80 to 130 beats per minute
Toddlers (2 to 4 years) 80 to 120 beats per minute
Preschoolers (4 to 6 years) 75 to 115 beats per minute
School age children (6 to 10 years) 70 to 110 beats per minute
Adolescents (10 to 15 years) 60 to 100 beats per minute
15 to 40 years 60 to 100 beats per minute
Adults over 40 60 to 100 beats per minute
Well-trained athletes 40 to 60 beats per minute

As you can see from the table, normal resting heart rate declines as children grow up and tends to rise again past middle age. Athletes often have very low resting heart rates due to their increased heart efficiency.

Is a resting heart rate of 100 beats per minute too high?

A heart rate of 100 beats per minute is at the upper end of the normal range. If your resting heart rate is consistently around 100 bpm or higher, it could potentially signify an issue that may need medical attention. Some possible causes include:

Lack of physical fitness:

Poor cardiovascular fitness is commonly associated with higher resting heart rates. The less active you are, the harder your heart has to work to pump blood when you are at rest. Regular exercise strengthens the heart muscle and allows it to pump more blood with less effort.

Stress or anxiety:

High stress levels activate the body’s fight-or-flight response, which causes the heart to beat faster. Chronic stress and anxiety disorders can cause your heart rate to remain elevated even when at rest.

Medications:

Some medications, such as certain asthma drugs, stimulants, decongestants, and thyroid hormones can increase resting heart rate as a side effect. Check with your doctor if you think a medication may be raising your heart rate.

Caffeine or nicotine:

Consuming stimulants like caffeine or nicotine before measuring your heart rate can temporarily push up your numbers. Avoid these substances for several hours before checking your resting rate.

Sleep deprivation:

Not getting enough good quality sleep can lead to higher resting heart rates. Aim for 7-9 hours per night.

Underlying medical conditions:

Certain medical conditions that affect the heart, blood vessels or hormones can raise your resting heart rate. These include an overactive thyroid (hyperthyroidism), low red blood cell count (anemia), heart damage from a previous heart attack, heart valve abnormalities, and others. Diabetes and high blood pressure can also accelerate heart rate.

Should you be concerned if your resting heart rate is 100 bpm?

A heart rate of 100 beats per minute may not necessarily be a major concern in an otherwise healthy person with no symptoms. However, if your resting heart rate persists at 100 bpm or higher, it would be prudent to investigate further and consult your doctor, especially if you are experiencing any other symptoms.

Some signs that an elevated resting heart rate may be problematic include:

– You have risk factors for heart disease

If you smoke, have high cholesterol, high blood pressure, diabetes, or a family history of early heart disease, a heart rate of 100 bpm or more warrants medical assessment.

– You experience symptoms like chest pain, dizziness, fatigue

An accelerated heart rate in combination with symptoms related to the heart is reason to see your doctor promptly.

– You have a heart condition or take certain medications

If you have been diagnosed with a heart problem or take drugs that can impact heart function, an elevated resting rate should be evaluated by your healthcare provider.

– Your heart rate spikes with minimal exertion

If simple daily activities like walking briskly, climbing stairs, or light housework causes your heart rate to suddenly jump up, consult your doctor.

– Your heart rate remains high after recovering from exercise

Your heart rate should return to near resting levels shortly after finishing moderate exercise. If it stays elevated for more than a few minutes, this could signify inadequate heart function.

– You have unexplained, persistent fatigue

A chronically high resting heart rate can be associated with reduced blood flow and oxygen delivery, which may result in tiredness, shortness of breath, or problems concentrating.

How to check your resting heart rate

It’s easy to monitor your resting heart rate at home, simply follow these steps:

1. Measure first thing in the morning

Take your resting heart rate first thing when you wake up in the morning, before getting out of bed. This provides the most accurate measure of your true resting rate.

2. Use a heart rate monitor or take your pulse

You can use a fitness tracker, smart watch, or phone app to record your heart rate. Alternatively, you can manually check your pulse by placing two fingers on your wrist or the side of your neck and counting the number of beats for 60 seconds.

3. Find a quiet place and relax for 5 minutes

Sit or lie down in a calm environment before checking your heart rate. Take normal breaths and relax your muscles to attain an accurate resting rate.

4. Record your resting heart rate for 7 mornings

Measure your morning resting heart rate for one week to determine your average. Compare this to normal ranges for your age and fitness level.

5. Tell your doctor if your rate is consistently over 100 bpm

If your average weekly resting heart rate is over 100 beats per minute, contact your doctor. They can help determine if it signifies an underlying medical issue.

Tips to lower your resting heart rate

If your resting heart rate is on the high side, here are some lifestyle changes that may help bring it down closer to a normal range:

– Increase aerobic exercise

Aim for at least 150 minutes per week of moderate exercise like brisk walking, swimming, or cycling. This strengthens the heart muscle.

– Add high intensity interval training (HIIT)

HIIT workouts that combine short bursts of intense activity with recovery periods help boost cardiovascular fitness.

– Lose excess weight

If overweight, losing even a small amount of weight can significantly lower resting heart rate.

– Reduce stress through yoga, meditation

Yoga, meditation, deep breathing, and other relaxation techniques help counter the heart rate accelerating effects of chronic stress.

– Limit stimulants like caffeine, energy drinks

Cutting back on stimulants that can temporarily increase heart rate allows your body to rest at a lower rate.

– Follow a heart healthy diet

Eat a diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats to support heart health.

– Optimize sleep habits

Aim for 7-9 hours of good quality sleep per night to allow the heart rest. Implement good sleep hygiene habits.

– Stay well hydrated

Drink enough water and fluids daily to prevent dehydration which can raise heart rate.

Conclusion

A resting heart rate up to 100 beats per minute can be normal, especially for less active individuals. However, it is at the upper threshold of normal and could potentially signify emerging health issues.

If your resting heart rate persistently exceeds 100 bpm, it is wise to have a medical checkup. Your doctor can help determine if your higher heart rate is something to worry about, particularly if you have cardiac risk factors or symptoms.

With lifestyle adjustments like increased exercise, stress reduction, and a healthy diet, you may be able to bring your resting heart rate back down into a more ideal range. Take steps to monitor your heart rate regularly and discuss any concerning numbers with your healthcare provider.
