Emotion Effect to Heart

There are six responses that scientist commonly look at to study emotions. These are heart rate, blood pressure, blood volume, electrodermal responses, muscle potential, and brain wave patterns, or electroencephalograms (EEGs). All are controlled by the nerveous system.

Hear Rate
This is the physiological response we think of first in connection with emotional situations, both because we recognize a thumping heart so clearly and because of the heart's mythic role as the center of emotions, where love, rage, and hatred supposedly holdsway. Nowadays, science uses exact tecniques to measure what the romantics once believed to be indescribable. Heart rates are commonly about 70 beats per minute (BPM), but they can fluctuate between 50 and 100 BPM, depending on emotions or other factors.
