Often noon heart rate rises from 80 to more than 90, normal?

The heart rate often rises from 80 beats/min to more than 90 beats/min at noon. Whether it is normal or not needs to be analyzed in combination with specific conditions.

For normal adults, the normal heart rate range is usually 60-100 beats/min, which can be affected by many factors, including eating, exercise and emotional changes. At noon, because of food intake, increased activity or emotional excitement, it may lead to an increase in heart rate. As long as it is within 100 beats/min, there are no other discomfort symptoms, and it is usually normal. However, if the heart rate increases, it is accompanied by obvious discomfort, such as chest tightness, shortness of breath, palpitations or chest pain, which is usually abnormal and may be related to hypertension, atherosclerosis, coronary heart disease and other diseases.
