Factors Affect Heart Rate
Your normal heart rate can vary, depending on many factors:
– Body size: people with obesity tend to have a higher heart rate at rest than usual. However, it should not exceed 100 bpm.
– Air temperature: the heart tends to beat faster when the humidity and temperature increase.
– Medications: beta-blockers and similar drugs can block adrenaline and decrease heart rates. Also, taking too much thyroid drugs would increase your heart rates.
– Emotion: anxiety and stress can increase heart rates. Therefore, you should live a happy life and improve your mood to prevent heart disease.
– Body position: standing suddenly after a period of sitting or resting would increase heart rate. This can be clearly noticed when you feel a bit dizzy. [4]
