+    <h1>Factors Affecting Heart Rate</h1>
+
+    <ul>
+        <li>
+            <h2>Temperature</h2>
+            <p>The change in air or body temperature can influence your heart rate. Extreme temperatures, either too
+                cold or too hot, can cause a slight increase in heart rate, usually 5 to 10 beats per minute. High
+                humidity can also contribute to an elevated heart rate.</p>
+        </li>
+        <li>
+            <h2>Body Position</h2>
+            <p>Your heart rate typically remains stable with different body positions. However, a sudden change, such as
+                standing up, can lead to a temporary increase in heart rate for the first 15 to 20 seconds.</p>
+        </li>
+        <li>
+            <h2>Emotions</h2>
+            <p>Intense emotions and stressful situations can lead to an elevated heart rate.</p>
+        </li>
+        <li>
+            <h2>Body Size</h2>
+            <p>Individuals with severe obesity may experience a slightly faster pulse, generally not exceeding 100 beats
+                per minute.</p>
+        </li>
+        <li>
+            <h2>Caffeine and Nicotine</h2>
+            <p>Caffeine-containing beverages and nicotine can raise your heart rate. The peak effect of caffeine on
+                heart rate occurs within one hour and lasts for 4 to 6 hours.</p>
+        </li>
+        <li>
+            <h2>Alcohol</h2>
+            <p>Consuming more than five alcoholic beverages for men or four for women within two hours can lead to an
+                irregular and rapid heart rate.</p>
+        </li>
+        <li>
+            <h2>Saturated Fat and Sodium</h2>
+            <p>Excessive sodium intake can prompt an increase in heart rate as the heart pumps more blood to dilute it.
+                Saturated fat consumption can raise cholesterol levels, potentially affecting heart activities and
+                increasing heart rate.</p>
+        </li>
+        <li>
+            <h2>Medications</h2>
+            <p>Beta blockers may result in a slow heart rate, while an excess of thyroid hormone can cause the heart to
+                beat harder and faster, potentially triggering abnormal rhythms.</p>
+        </li>
+        <li>
+            <h2>Age</h2>
+            <p>As you age, your resting heart rate (RHR) may not change significantly, but your training heart rate
+                (THR) may become slower.</p>
+        </li>
+        <li>
+            <h2>Gender</h2>
+            <p>The average resting heart rate is higher in women than in men. However, women generally have a lower risk
+                of cardiac diseases.</p>
+        </li>
+        <li>
+            <h2>Exercise</h2>
+            <p>Regular exercise gradually lowers your resting heart rate and reduces the risk of death associated with a
+                high resting heart rate.</p>
+        </li>
+    </ul>

+    <h1>Heart Diseases</h1>
+
+    <ul>
+        <li>
+            <h2>Overview</h2>
+            <p>Heart disease encompasses several types of heart conditions, collectively known as cardiovascular
+                diseases. These conditions affect the heart and blood vessels in various ways.</p>
+        </li>
+        <li>
+            <h2>Congenital Heart Disease</h2>
+            <p>A type of heart condition present at birth, congenital heart disease includes abnormalities such as
+                atresia, septal abnormalities, and atypical heart valves. Some congenital cardiac abnormalities may not
+                show symptoms and could go undetected.</p>
+        </li>
+        <li>
+            <h2>Coronary Artery Disease (CAD)</h2>
+            <p>The most prevalent cardiac illness, CAD causes narrow or obstructed coronary arteries, leading to chest
+                pain, heart attacks, or strokes. Atherosclerosis, or hardening of the arteries, is a common cause
+                affecting blood flow and oxygen/nutrient supply to the heart.</p>
+        </li>
+        <li>
+            <h2>Arrhythmia (Abnormal Heart Rhythms)</h2>
+            <p>An arrhythmia occurs when the heart's muscle cannot control internal electrical impulses, resulting in
+                excessively fast, slow, or irregular heartbeats. While most arrhythmias are harmless, some may cause
+                symptoms requiring immediate medical attention.</p>
+        </li>
+        <li>
+            <h2>Heart Valve Disease</h2>
+            <p>Heart valve disease occurs when one or more heart valves fail to open and close properly, affecting blood
+                flow. It can be inherited or caused by factors like high blood pressure, CAD, heart infections, or heart
+                attacks.</p>
+        </li>
+        <li>
+            <h2>Dilated Cardiomyopathy</h2>
+            <p>In dilated cardiomyopathy, the heart muscle becomes strained, thickened, or stiff, leading to issues like
+                arrhythmia, blood clots, and heart failure. This condition typically affects individuals between the
+                ages of 20 and 60.</p>
+        </li>
+        <li>
+            <h2>Pericardial Disease</h2>
+            <p>Pericardial disease refers to conditions affecting the pericardium, including pericarditis
+                (inflammation). Pericarditis can occur in patients who have had open-heart surgery.</p>
+        </li>
+        <li>
+            <h2>Heart Failure</h2>
+            <p>Heart failure occurs when the heart cannot efficiently pump blood to meet the body's demands. Causes
+                include untreated CAD, high blood pressure, and arrhythmias. Early treatment and lifestyle modifications
+                are crucial as heart failure cannot be cured once diagnosed.</p>
+        </li>
+        <li>
+            <h2>Prevention and Management</h2>
+            <p>Various conditions, including hypertension, diabetes, coronary disease, and infections, can aggravate
+                heart disease. Regular heart screening programs are recommended for early diagnosis and management.
+                Consult a heart specialist for personalized advice based on screening results.</p>

+    <h1>Heart Rate Zones of Children</h1>
+
+    <ul>
+        <li>
+            <h2>Introduction</h2>
+            <p>After knowing their THR (Target Heart Rate) and RHR (Resting Heart Rate) ranges, many parents wish to
+                know whether their children's pulse or heart rate zone can be different or not. The truth is that
+                children may have a higher heart rate than adults. Let's read on to know more.</p>
+        </li>
+        <li>
+            <h2>Resting Heart Rate Zone</h2>
+            <p>It has been proved that children's heart size is smaller and their stroke and blood volume are lower than
+                adults'. Therefore, their resting heart rate zone usually is higher than that of adults.</p>
+            <p>What needs to be mentioned is that although adult men and women can have different heart rate ranges, the
+                maximum heart rate difference during a young age and adolescence between boys and girls is very small.
+                The actual heart rate varies by child and is likely genetically determined.</p>
+        </li>
+        <li>
+            <h2>Healthy Resting Heart Rate Ranges</h2>
+            <ul>
+                <li>Newborns (ages 0 to 1 month): 70 to 190 beats per minute</li>
+                <li>Infants (ages 1 to 11 months): 80 to 160 beats per minute</li>
+                <li>Children (ages 1 to 2 years): 80 to 130 beats per minute</li>
+                <li>Children (ages 3 to 4 years): 80 to 120 beats per minute</li>
+                <li>Children (ages 5 to 6 years): 75 to 115 beats per minute</li>
+                <li>Children (ages 7 to 9 years): 70 to 110 beats per minute</li>
+                <li>Children (ages 10 to 15 years): 70 to 100 beats per minute</li>
+                <li>Children (over 15 years old): 60 to 100 beats per minute</li>
+            </ul>
+        </li>
+        <li>
+            <h2>Healthy Target Heart Rate</h2>
+            <p>Your child's target heart rate is decided by maximum heart rate. The actual heart rate varies by child.
+                It is healthy for your child to exercise with a heart rate between 50% to 85% of his or her maximum
+                heart rate.</p>
+            <p>Also, to save your time, you can use our app to check the RHR and THR of your child. We provide both
+                children's RHR measurement and THR automatic calculation to cater to your needs and help you take care
+                of your child better.</p>

+        <li>
+            <h2>Introduction</h2>
+            <p>Usually, your heart rate can occasionally exceed the normal range, which is normal when you are
+                exercising, under stress, or have a related disease.</p>
+        </li>
+        <li>
+            <h2>Signs of Concern</h2>
+            <p>If your resting heart rate rises over 100 beats per minute not because of psychological stress, it may be
+                a sign of a serious heart condition, tachycardia. Tachycardia can increase the risk of stroke, heart
+                failure, sudden cardiac arrest, and even death.</p>

+            <p>The Copenhagen Male Study in 1971, monitoring 3,000 middle-aged men's health and resting heart rate for
+                16 years, discovered that every 10 to 22 increase in resting heart rate per minute raised the risk of
+                death by 16%. For instance, people who had a resting heart rate over 90 beats per minute elevated their
+                risk of death by 120% to 150%.</p>

+

+        <li>
+            <h2>Introduction</h2>
+            <p>If you wish to know your current or future heart health condition, resting heart rate (RHR) is an
+                important indicator you must know.</p>
+        </li>
+        <li>
+            <h2>Importance of RHR</h2>
+            <p>As everyone knows, the heart pumps blood and oxygen throughout the body to keep it functioning well. The
+                RHR is the number of heart beats per minute while you're at rest, showing whether your heart muscle is
+                functioning well or not.</p>
+            <p>People with healthy hearts usually have RHR between 60 and 100 beats per minute. Irregularities, or
+                values lower than 60 or higher than 100 per minute, may indicate potential heart problems that should be
+                brought to the attention of you and your doctor.</p>
+        </li>
+        <li>
+            <h2>Measuring RHR</h2>
+            <p>To measure your RHR, find a time when you are at rest, put your index and middle finger on the thumb side
+                of your wrist or on either side of your neck to feel the pulse. Count how many times it beats in 30
+                seconds and double the number to calculate your RHR per minute.</p>
+            <p>An alternative is to use our app, which only requires showing one of your fingertips under your mobile
+                camera to calculate your RHR.</p>
+        </li>
+        <li>
+            <h2>Ensuring Accuracy</h2>
+            <p>To ensure accuracy and identify irregularities, it is recommended to measure your RHR multiple times
+                throughout the day or week and calculate an average number.</p>
+            <p>Your RHR may change throughout the day due to environmental factors, activity levels, measurement timing,
+                etc.</p>
+        </li>
+        <li>
+            <h2>Best Practices</h2>
+            <p>For the most accurate results, the American Heart Association recommends checking your RHR in the morning
+                after a night's sleep and before getting out of bed. Additionally, wait for at least one to two hours
+                after consuming caffeine, exercising, or experiencing a stressful situation.</p>

+
+    <ul>
+        <li>
+            <h2>Introduction</h2>
+            <p>Target heart rate (THR or training heart rate) is the suggested range of how often your heart beats
+                during exercise for improving health. It is an important index for you to exercise safely.</p>
+        </li>
+        <li>
+            <h2>Calculating Maximum Heart Rate</h2>
+            <p>Your THR depends on the highest number of times your heart can beat in one minute, which is your maximum
+                heart rate. For men, the estimated maximum heart rate can be calculated as 220 minus their age. For
+                women, the Northwestern Medicine research suggests using the equation HRmax = 206 - (0.88 x your age) to
+                get an accurate result.</p>
+        </li>
+        <li>
+            <h2>Target Heart Rate Zones</h2>
+            <p>If you are doing moderate-intensity activity, your THR should be between 50% to 70% of your maximum heart
+                rate. For vigorous exercise, your THR should be between 70% to 85% of your maximum heart rate.</p>
+            <p>For example, a 40-year-old man's maximum heart rate is 180 (220 - 40). The THR should be 50% to 85% of
+                180, in other words, 90 to 153 beats per minute.</p>
+        </li>
+        <li>
+            <h2>Using the App for Accuracy</h2>
+            <p>If you are training to burn body fat or improve your cardiovascular health, you can use our app to get
+                more accurate and scientific THR automatically. Simply input your age and gender, specify your activity
+                level (warm-up, moderate training, high-intensity training, or extremely vigorous workout), and the app
+                will provide you with the appropriate target heart rate.</p>
+            <p>This eliminates the need for manual calculations and ensures precision in determining your THR.</p>

+    <h1>Understanding Heart Rate</h1>
+
+    <p>Your heart rate, also known as pulse, represents the number of heartbeats per minute.</p>
+
+    <p>With each heartbeat, the heart pumps blood throughout the body, supplying oxygen for proper bodily functions. The
+        heart's workload in circulating blood varies based on different states, such as rest or exercise.</p>
+
+    <p>Two key heart rate indexes are the resting heart rate and target heart rate. The resting heart rate measures how
+        your heart beats when you are at rest, while the target heart rate indicates the ideal rate during exercise.</p>
