Your resting heart rate is the number of times your heart beats each minute when your body is calm and at rest. For many adults, a resting heart rate between 60 and 100 beats per minute is considered within a typical range. Some healthy, physically active people have resting heart rates below 60. That does not automatically mean something is wrong, but a low or high number should always be interpreted in context.
If your resting heart rate has been creeping upward, or you simply want to improve your cardiovascular fitness, there are evidence-based steps that may help. Regular aerobic activity, adequate sleep, hydration, stress management, avoiding tobacco and reviewing medicines or stimulants with a clinician can all affect heart rate. The most important point is that you should focus on your overall health rather than trying to force your pulse toward a specific target.
Do not try to manage a concerning heart rate at home if it is accompanied by chest pain, severe shortness of breath, fainting, new weakness, confusion, collapse or another symptom that feels like an emergency.
What does resting heart rate tell you?
Heart rate is controlled by a balance between the electrical system of the heart, the autonomic nervous system, hormones, medications, activity level and your body's immediate needs. When you exercise, have a fever, feel anxious or become dehydrated, your body may ask the heart to pump faster. When you sleep or relax, the heart usually slows.
A single reading rarely tells the whole story. Resting heart rate becomes more useful when you look at the pattern over time. For example, a person whose usual resting pulse is around 68 beats per minute may notice that it is repeatedly in the high 80s for several days. That change could be related to poor sleep, illness, dehydration, pain, stress, a new medicine or another health issue. The trend is often more informative than comparing your number with someone else's.
Age, pregnancy, fitness, thyroid function, anaemia, infection, heart rhythm disorders and certain medicines can all influence pulse rate. Because of these variables, “lower” is not always “better.” A very low heart rate can be normal in a trained athlete, while the same number in someone who feels dizzy or faint may need assessment.
Think in ranges, symptoms and trends — not one perfect number.
General adult guidance only. Children, pregnant people, athletes and people taking certain medicines may have different expected ranges.
How to measure resting heart rate correctly
Before deciding that your heart rate is “too high,” make sure you are measuring it under resting conditions. Checking immediately after climbing stairs, drinking coffee, rushing to work or feeling upset will not give you a true resting value.
For a useful home measurement, sit quietly for five to ten minutes. Keep your feet supported and avoid talking. You can feel the pulse on the thumb side of your wrist with your index and middle fingers. Count the beats for 60 seconds, or count for 30 seconds and multiply by two. A validated wearable or blood-pressure monitor can also provide useful trend information, but any device can produce occasional errors.
Try measuring at a similar time each day for several days rather than checking repeatedly throughout the day. Frequent checking can increase anxiety and make normal fluctuations feel more important than they are. If you are keeping a record for a clinician, note the pulse, the time of day, any symptoms, medicines taken and what you were doing beforehand.
How to lower your resting heart rate safely
1. Build aerobic fitness gradually
Regular aerobic activity is one of the most reliable ways to improve cardiovascular efficiency. Walking briskly, cycling, swimming, jogging and other forms of continuous movement train the heart to pump more blood with each beat. Over time, many people find that the heart does not need to beat as frequently at rest.
If you are inactive, start with manageable sessions and increase duration and intensity gradually. You do not need to exercise at maximum effort to benefit. Consistency matters more than occasional hard workouts. If you have known heart disease, significant symptoms or major medical conditions, ask your clinician what level of activity is appropriate before starting a new programme.
2. Prioritise sleep
Poor sleep can increase sympathetic nervous system activity, stress hormones and daytime fatigue. In some people, this contributes to a higher resting pulse. Aim for a consistent sleep schedule and enough time in bed to feel rested. If loud snoring, choking during sleep, morning headaches or severe daytime sleepiness are common, discuss possible sleep apnoea with a healthcare professional because untreated sleep-disordered breathing can affect cardiovascular health.
3. Stay adequately hydrated
When you are dehydrated, circulating blood volume can fall. The body may compensate by increasing heart rate. Drinking enough fluid throughout the day is therefore a simple but important part of cardiovascular health, especially in hot weather, during exercise, after vomiting or diarrhoea, or when you have a fever. People with heart failure, kidney disease or other conditions that require fluid restriction should follow the advice of their clinical team rather than increasing fluid intake on their own.
4. Reduce unnecessary stimulant exposure
Caffeine affects people differently. Some can drink coffee without a noticeable pulse change, while others experience palpitations or a faster heart rate. Energy drinks, high-dose caffeine products, nicotine, some decongestants and certain performance supplements can also raise heart rate. If you suspect a stimulant is contributing, reduce it gradually and discuss medicines or supplements with a pharmacist or doctor before stopping anything prescribed.
5. Manage stress in ways you can sustain
Stress and anxiety activate the body's “fight or flight” response, which can raise heart rate even when you are sitting still. Slow breathing, regular physical activity, mindfulness, prayer, time outdoors, counselling and reducing avoidable stressors can all be useful. The best approach is one you can repeat consistently. If anxiety is persistent, interferes with sleep or causes frequent panic symptoms, professional support can help.
Support a healthier resting pulse without chasing a number.
If your pulse is persistently high or low, lifestyle changes should not replace medical assessment.
6. Stop smoking and avoid nicotine
Nicotine stimulates the cardiovascular system and can increase heart rate and blood pressure. Stopping smoking has benefits that extend far beyond pulse rate, including lower risks of heart attack, stroke, lung disease and several cancers. If you smoke, ask about behavioural support and evidence-based smoking-cessation options.
7. Limit excess alcohol
Alcohol can affect sleep, hydration, blood pressure and heart rhythm. Heavy or binge drinking can trigger palpitations and, in some people, abnormal rhythms such as atrial fibrillation. If alcohol seems to raise your pulse or cause irregular beats, reducing intake is sensible. People who drink heavily every day should seek medical advice before abruptly stopping because withdrawal can be dangerous.
8. Treat underlying medical problems
Sometimes a faster resting pulse is not primarily a fitness problem. Fever, anaemia, overactive thyroid, infection, pain, lung disease, pregnancy-related changes, low blood pressure and heart rhythm disorders can all increase heart rate. The right treatment is to address the underlying cause rather than simply trying to slow the pulse.
Similarly, a slow heart rate can occur because of medicines such as beta blockers or because of problems with the heart's electrical conduction system. Never change a prescribed heart medicine just to alter your pulse without speaking with the clinician who manages it.
What about breathing exercises?
Slow, controlled breathing may help lower heart rate temporarily by increasing parasympathetic activity and reducing the stress response. A simple approach is to breathe in gently through the nose, allow the abdomen to expand, and exhale slowly for slightly longer than the inhalation. Continue for several minutes without forcing the breath.
Breathing exercises can be useful for relaxation, but they do not treat an abnormal rhythm or a medical cause of persistent tachycardia. If your heart is racing unexpectedly, particularly with chest pain, faintness or difficulty breathing, seek medical attention instead of relying on a breathing technique.
Can losing weight lower resting heart rate?
For someone who is overweight, gradual weight loss achieved through sustainable nutrition and physical activity may improve cardiovascular fitness, blood pressure, insulin sensitivity and sleep quality. Those changes can contribute to a healthier resting heart rate. However, rapid weight-loss plans, dehydration and stimulant-based products can have the opposite effect and may provoke palpitations.
Focus on overall cardiometabolic health rather than using resting heart rate as the only measure of success. Blood pressure, cholesterol, blood glucose, activity tolerance, sleep, waist circumference and how you feel during everyday tasks all provide useful information.
When should you talk to a doctor about your heart rate?
Book a medical review if your resting heart rate is repeatedly above 100 beats per minute without an obvious temporary reason, if it is much higher or lower than your usual baseline for several days, or if you frequently feel palpitations. A clinician may review your history, medicines and symptoms, perform an examination, and decide whether tests such as an ECG, blood tests, thyroid tests or other investigations are appropriate.
A lower heart rate also deserves assessment when it is associated with dizziness, fainting, unusual fatigue, shortness of breath, exercise intolerance or confusion. The number alone is not the diagnosis; the combination of the rate, rhythm, symptoms and clinical context matters.
Seek urgent help for chest pain or pressure, severe breathlessness, collapse, fainting, sudden weakness, a new severe irregular heartbeat or symptoms that are rapidly worsening. In Uganda, use your local emergency services or contact the Case emergency team if care cannot wait.
How long does it take to lower resting heart rate?
There is no single timeline. Improvements related to aerobic fitness may develop over weeks to months of consistent activity. A pulse elevated because of dehydration or acute stress may settle much sooner. A rate caused by anaemia, thyroid disease, infection or an arrhythmia may not improve until the underlying problem is treated.
Track progress over longer periods rather than judging your health from day-to-day changes. If you use a smartwatch, look at weekly or monthly trends and compare readings taken under similar conditions. Bring the data to an appointment if you are concerned, but remember that consumer devices are not a substitute for an ECG or clinical diagnosis.
How medicines can affect your resting heart rate
Many medicines can change heart rate, either intentionally or as a side effect. Beta blockers and some calcium-channel blockers are commonly used to slow the heart in conditions such as high blood pressure, angina and certain rhythm disorders. Other medicines, including some asthma treatments, thyroid medicines, stimulants, decongestants and some psychiatric medicines, can increase pulse rate in some people.
If your resting heart rate changed after starting, stopping or changing the dose of a medicine, tell the clinician who prescribed it. Do not adjust the dose on your own simply because of a smartwatch or home pulse reading. The reason the medicine was prescribed, your blood pressure, symptoms and other health conditions all need to be considered together. A pharmacist can also help identify over-the-counter products that may contain stimulants.
What if your resting heart rate is higher when you are sick?
A temporary increase in heart rate is common during illness. Fever, dehydration, pain, infection and poor sleep can all make the heart beat faster. In those situations, the pulse often settles as the underlying problem improves. The important question is whether the increase fits with what is happening and whether you have warning symptoms.
If the rate is very fast, remains elevated after the illness improves, feels irregular or is accompanied by chest pain, fainting, severe breathlessness or marked weakness, seek medical assessment. Persistent tachycardia can place additional demand on the heart and sometimes points to a problem that needs treatment.
Resting heart rate and blood pressure are not the same thing
Heart rate and blood pressure are related, but they measure different things. Heart rate tells you how many times the heart beats each minute. Blood pressure measures the force of blood against the artery walls. You can have a normal pulse and high blood pressure, a fast pulse and normal blood pressure, or many other combinations.
That is why a complete cardiovascular check often looks at both numbers together, along with symptoms, cholesterol, blood glucose, family history, smoking status, weight, activity level and other risk factors. If you are tracking your cardiovascular health at home, record your pulse and blood pressure separately rather than assuming one predicts the other.
Frequently asked questions about resting heart rate
Is 60 beats per minute too low?
Not necessarily. A resting rate around 60 can be normal, especially in physically active adults. What matters is whether the number is usual for you and whether you have symptoms such as dizziness, fainting, unusual fatigue or shortness of breath.
Is 90 beats per minute normal at rest?
A resting pulse of 90 falls within the broad 60–100 beats-per-minute range often used for adults, but a persistent increase from your usual baseline may still be worth discussing with a clinician. Trends and symptoms matter more than one isolated reading.
Can walking lower resting heart rate?
Regular brisk walking can improve aerobic fitness and may lower resting heart rate over time. Start at a pace you can sustain and increase duration gradually. People with significant cardiovascular symptoms should ask for medical advice before increasing exercise intensity.
Can anxiety make resting heart rate stay high?
Yes. Ongoing stress and anxiety can keep the body's sympathetic nervous system more active and raise pulse rate. However, persistent tachycardia should not automatically be blamed on anxiety without considering other causes such as anaemia, thyroid disease, infection, medicines or a heart rhythm problem.
Bottom line
A healthy resting heart rate is not about reaching the lowest possible number. It is about helping your cardiovascular system work efficiently while paying attention to symptoms and your personal baseline. Regular aerobic exercise, good sleep, appropriate hydration, stress management, avoiding nicotine, limiting excess alcohol and reviewing stimulants can all support heart health. Persistent or symptomatic changes deserve medical assessment.
