When you wake up in the morning, a heart rate of 67 during the day and 90 during the day is in the normal range. A normal heart rate ranges from 60 to 100 beats per minute. Heart rate can be affected by age, lifestyle habits, mood swings, etc. Generally, the heart rate of newborns, infants and young children is relatively fast, and gradually slows down with age, and then mildly increases in advanced age. It is also affected by emotions, such as excitement, fear, sadness, anger and anxiety, all of which can increase the heart rate. Finally, it is also affected by lifestyle habits. A good night’s rest and sleep may slow down the heart rate, while exercise may speed it up. Drinking tea, coffee, stimulants or certain medications may also increase the heart rate. If you have an abnormal heart rate or are not feeling well, please go to the hospital in time to avoid delaying your condition.
