1. Age: Heart rate tends to decrease with age. Newborns have a higher heart rate compared to adults, and it gradually decreases as they grow older.
2. Physical activity: Engaging in physical activity or exercise increases heart rate. This is because the heart needs to pump more blood to supply oxygen and nutrients to the muscles.
3. Emotional state: Emotions such as stress, anxiety, or excitement can cause an increase in heart rate. This is due to the release of stress hormones like adrenaline, which can stimulate the heart.
4. Body temperature: An increase in body temperature, such as during fever or intense physical activity, can lead to an elevated heart rate. This is because the heart needs to work harder to regulate body temperature.
5. Medications and substances: Certain medications, such as beta-blockers or stimulants, can affect heart rate. Additionally, substances like caffeine or nicotine can also increase heart rate.
6. Health conditions: Various health conditions can impact heart rate. For example, an overactive thyroid gland (hyperthyroidism) can cause an increased heart rate, while certain heart diseases or conditions like heart failure can lead to a decreased heart rate.
7. Body position: Changes in body position, such as standing up quickly from a sitting or lying position, can cause a temporary increase in heart rate. This is known as orthostatic or postural tachycardia.
