How Does Heart Rate Change During Sleep
In general, heart rate is slower during sleep than when a person is awake. However, heart rate also changes as a sleeper cycles through the different stages of sleep. In the first stages of light sleep, heart rate begins to slow. During deep sleep, the heart rate reaches its lowest levels. In rapid eye movement sleep, heart rate may speed up to a heart rate similar to when you are awake.
Most people experience a more relaxed heart rate during non-rapid eye movement sleep, which helps protect against cardiovascular events. By contrast, REM sleep is often marked by periods of higher activity. While this is considered normal, researchers believe that the surge in activity during REM sleep could explain why already vulnerable people often experience heart attacks and other events in the early morning hours, which is typically spent more in REM sleep.
Sleep problems can have negative impacts on your heart and cardiovascular health, increasing your heart rate and contributing to higher blood pressure. Disorders such as sleep apnea, periodic limb movements, or shift work disorder that interfere with sleep have been linked to a higher chance of developing cardiovascular disease.
How Can You Find Out Your Resting Heart Rate
Fitness trackers with heart rate monitors can be surprisingly accurate. But you don’t have to rely on technology to get your numbers.
“The best way to determine your resting heart rate is to learn to take your pulse, says Dr. Mittal. This can be taken by palpating the pulse at your wrist or neck.
Here’s how to do it: Place your index and third fingers on your neck to the side of your windpipe. If you want to check it at your wrist, place two fingers between the bone and the tendon, looking for your radial arterywhich is located on the thumb side of your wrist.
Once you find your pulse, count the number of beats in 15 seconds, then multiply that number by 4 to calculate your beats a minute, according to the Mayo Clinic.
While your heart rate may vary, it’s important to keep a healthy base rate. Once you know what that is for your body, keep tabs. If you start to notice changes with your heart rate, you should check in with your doctor, especially if you notice it consistently dipping way below your normal resting heart rate, or have frequent episodes of unexplained fast beating.
“If you’re a regular exerciser, but start to notice your routine takes more effort, or if you’re breathless or more tired than normal during your workout, it’s time to see a doctor,” says Traynor.

Irregular Heart Rate Causes
The most common cause of arrhythmia or irregular heart rate is atrial fibrillation, which can cause a fast heart rate.
Other factors may contribute to an abnormally high heart rate, including:
- Age Your heart rate will increase as you age.
- Medications Some medications block adrenaline, slowing your heart rate.
- Fitness level The more physically active you are the better your hearts fitness and the lower your heart rate.
- Stress level Being stressed can lead to a higher heart rate.
- Body mass Being overweight or obese can lead to a higher heart rate.
- Body position Standing up may result in a higher heart rate than lying down.
When Changes In Heart Rhythms Warrant A Physicians Attention
Though most fluctuations in heart rhythms will likely be harmless, there are times your first response should be to seek medical advice.
- Your symptoms are sudden and abnormal. If theres a clear first time that you notice a rhythm change in your heart, its a good idea to alert your doctor, Anderson says. You should also call your doctor when a change in heart rhythms corresponds to chest pain, losing consciousness or a prolonged sense that you might pass out. Likewise, contact a medical professional if a rhythmic abnormality persists.
- Your history involves other heart issues. If you were born with a malformation if youve had heart surgery if youve had a heart attack or long-standing, untreated high blood pressure or if there is something otherwise abnormal with your heart and you notice abnormal heart rhythms, you should see your doctor.
- Your family history puts you at increased risk. Your doctor may ask you to attend more closely to changes in your heart rhythms if your family has a history of heart disease or sudden death.

Is Resting Heart Rate Different By Age
For most of us , between 60 and 100 beats per minute is normal.1 The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now thats chill!
When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness and higher blood pressure and body weight.2
Fast Resting Heart Rates
A heart rate that averages above 100 beats per minute is called tachycardia. You can develop a high heart rate because of things like fever, anemia, dehydration, or physical or emotional stress, which triggers the release of the fight-or-flight hormone adrenaline.
“Adrenaline is like gasoline on a fire for heart rate,” says Traynor. It can also lead to bigger problemseverything from fainting spells to more serious issues like blood clots that lead to stroke, or eventual heart failure .
Some research found that people with a resting heart rate at or above 84 beats per minute over the span of five years were 55 percent more likely to die of heart disease than were those with lower resting heart rates.

Know Your Numbers: Maximum And Target Heart Rate By Age
This table shows target heart rate zones for different ages. Your maximum heart rate is about 220 minus your age.3
In the age category closest to yours, read across to find your target heart rates. Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate, while during vigorous physical activity its about 70-85% of maximum.
The figures are averages, so use them as a general guide.
High Sleeping Heart Rate
With the possible exception of REM sleep, your heart rate should typically be lower during sleep than when you are awake. High heart rates are connected with taking longer to fall asleep and experiencing lower sleep quality, as well as an increased risk of cardiovascular disease.
- Stress and anxiety: Anxiety leads to an increased heart rate and higher blood pressure . Prolonged stress and anxiety can increase heart rate during sleep. Poor sleep, in turn, can negatively impact heart rate and blood pressure during the day.
- Sleep behaviors: Poor sleep hygiene can also contribute to a higher sleeping heart rate. One study found that shifting bedtime just 30 minutes later can raise resting heart rate during sleep, with effects that last into the following day. Waking up in the middle of the night can also increase your sleeping heart rate, as can nightmares.
- Pregnancy: As pregnancy progresses, heart rate may climb as it adapts to supply vital oxygen and nutrients to the growing fetus. Regular exercise may help lower resting heart rate and boost heart health during pregnancy.
- Other factors: Being sick with a fever can increase your heart rate. Certain medications may also increase heart rate. Caffeine and exercise can also trigger an increase in heart rate.

Medicines To Control Atrial Fibrillation
Medicines called anti-arrhythmics can control atrial fibrillation by:
- restoring a normal heart rhythm
- controlling the rate at which the heart beats
The choice of anti-arrhythmic medicine depends on:
- the type of atrial fibrillation
- any other medical conditions you have
- side effects of the medicine chosen
- how well the atrial fibrillation responds.
Some people with atrial fibrillation may need more than one anti-arrhythmic medicine to control it.
How To Lower Heart Rate
If your heart rate is too high there are ways to lower it safely. Your heart rate could be high after exercising or because youre feeling stressed or anxious.
Here are some fast-acting methods that can help lower a fast heart rate:
- Breathing exercises: You can use your breathing to raise the aortic pressure in your heart, which will lower your heart rate. To do this, close your mouth and nose and raise the pressure in your chest. Breathe in for five to eight seconds, hold it for three to five seconds, and then exhale slowly. This can be repeated several times.
- Taking a bath: This can help relax you and bring your heart rate down.
- Light yoga: Calming yoga or meditation can help relax you and bring a high heart rate down.
- Moving to a cooler location: If your heart rate is raised because youre too hot, moving to a cooler location will help bring it down.
Here are some long-term solutions that can help you achieve a healthy heart rate:
- Exercising regularly: Starting and keeping an exercise program will help decrease resting heart rates over time.
- Eating healthy:Healthy diets that contain whole grains, leafy greens, fruits, and omega-3 fatty acids are great for supporting long term heart health and will help keep heart disease at bay.
- Quitting smoking:Non-smokers have a lowered risk of recurrent heart attacks and cardiovascular disease.
- Staying hydrated:Drinking enough water allows the heart to pump blood more easily throughout the body.

How Is Atrial Fibrillation Defined
Atrial fibrillation is defined in various ways, depending on how it affects you:
- paroxysmal atrial fibrillation – this comes and goes, usually stopping within 48 hours without any treatment.
- persistent atrial fibrillation – this lasts for longer than seven days, or less when it is treated.
- longstanding persistent atrial fibrillation – this means you have had continuous atrial fibrillation for a year or longer.
- permanent atrial fibrillation – this is when atrial fibrillation is present all the time and no more attempts to restore normal heart rhythm will be made

How To Measure Heart Rate
Measuring your heart rate is as simple as checking your pulse. You can find your pulse over your wrist or neck. Try measuring your radial artery pulse, which is felt over the lateral part your wrist, just below the thumb side of your hand.
To measure your heart rate, gently press the tips of your index and middle fingers over this blood vessel in your wrist. Make sure not to use your thumb, because it has its own pulse and may cause you to miscount. Count the beats you feel for a full minute.
You can also count for 30 seconds and multiply the count by two, or count for 10 seconds and multiply by six.
Alternatively, you can use a heart rate monitor, which determines your heart rate automatically. You can program it to tell you when youre above or below your target range.
What You Can Do For Your Heart Rate
You should always aim to take good care of your heart. This includes exercising regularly, eating heart-healthy foods, minimizing alcohol, and maintaining a moderate weight.
Additionally, you should visit your doctor regularly for physicals. Not only is it good practice, but it can also help with the early detection of high cholesterol or blood pressure abnormalities.
If you already have heart disease, you should carefully monitor your condition and stick to your treatment plan. Take all medications as instructed by your doctor. Be sure to promptly report any new or worsening symptoms.
Other heart health tips include:
- Find ways to reduce stress. Examples include things like yoga or meditation.
- Limit your caffeine intake when possible. Using too much caffeine can increase heart rate.
- Limit intake of energy drinks.
- Moderate your intake of alcohol. Women should only have one drink or less per day while men should have two or fewer drinks per day.
- Quit smoking. Smoking increases your heart rate, and quitting can help bring it back down.
- Avoid cannabis. Cannabis use

What Is A Dangerous Heart Rate
There are two types of dangerous heart rates:
- Too high Called tachycardia, its a heart rate consistently above 100 beats per minute.
- Too low Called bradycardia, its a heart rate below 60 beats per minute .
If your heart rate is too high or too low and/or you are also experiencing shortness of breath, make an appointment with your health care provider.
How Can You Measure Your Sleeping Heart Rate
To measure your sleeping heart rate at home, you can use a smart watch. Some companies are also starting to offer smart sensors that integrate into the bed. If your doctor suspects you may have a sleep disorder, they may order an in-lab or at-home sleep study with professional equipment that delivers a more accurate heart rate reading.
To calculate your resting heart rate during the day, lightly press the tips of your index and middle finger over the artery on your neck, your chest, or the inside of your wrist. Count your heartbeats for the next 30 seconds and multiply by two.

Whats A Normal Heart Rate
A heart rate is a measurement of the number of times the heart muscle beats per minute. Healthy kids and adults will have hearts that beat at different speeds because of their age and body size. If the heart is beating too fast or too slow, this could mean you have an underlying health problem. Your resting heart rate will also allow you to gauge your current heart health.
In general, a lower resting heart rate means the heart is beating less per minute, which likely means its more efficient. Your resting heart rate tells you how fast your heart is beating when youre in a relaxed state, like sitting or laying down. If your resting heart rate is too high, this might mean you have lower physical fitness, or that youre at risk of developing a heart condition.
Knowing what your target heart rate should be for your age can help you recognize if and when your heart rate is abnormal, which may be an indication that its time to go to the doctor.
| Normal heart rate by age | |
|---|---|
| Age | |
| 18 and older | 60-100 bpm |
As we get older, the range of whats considered to be a healthy normal resting heart rate will change.
The average healthy adult will have a resting heart rate of 60 bpm or higher. Although in clinical practice, the resting heart rate between 60 and 100 bpm is considered to be normal, people with a resting heart rate higher than 80 bpm could have an increased risk of developing cardiovascular disease.

How To Calculate Your Maximum Heart Rate
Generally, a healthy active heart rate is 60 to 80 percent of the highest your heart rate should safely go. The highest heart rate is called your maximum heart rate. A guideline for calculating your maximum heart rate is to subtract your age from 220, like this: 220 your age = your maximum heart rate

Why Does Atrial Fibrillation Happen And How Common Is It
Atrial fibrillation is the most common heart rhythm disturbance and affects up to 800,000 people in the UK.
The cause of atrial fibrillation is not fully understood, but it tends to occur in certain groups of people and may be triggered by certain situations, such as drinking excessive amounts of alcohol or smoking.
The condition can affect adults of any age or gender but:
- is more common the older you get
- affects about 10% of people over 75
- more common in men than women
Atrial fibrillation is more likely to occur in people with other conditions, such as:
- high blood pressure

What Your Heart Rate Is Telling You
Your pulse, both at rest and during exercise, can reveal your risk for heart attack and your aerobic capacity.
Your grandmother may have referred to your heart as “your ticker,” but that nickname has proved to be a misnomer. A healthy heart doesn’t beat with the regularity of clockwork. It speeds up and slows down to accommodate your changing need for oxygen as your activities vary throughout the day. What is a “normal” heart rate varies from person to person. However, an unusually high resting heart rate or low maximum heart rate may signify an increased risk of heart attack and death.
One simple thing people can do is to check their resting heart rate. It’s a fairly easy to do and having the information can help down the road. It’s a good idea to take your pulse occasionally to get a sense of what’s normal for you and to identify unusual changes in rate or regularity that may warrant medical attention.
