Highlights:
A rise in heart rate is associated with an increase in anxiety-related behaviors in mice. The findings show how bodily signals might influence affective behaviors related to emotions like worry and terror. - Standing on the edge, getting lost in a dark jungle, or dashing into a crush will cause your heart rate to increase as a physical reaction to your anxiousness
- Stanford Medicine researchers discovered evidence of the opposite in a new mouse study: Anxiety can be caused by a quicker heart rate
- This addresses a long-standing philosophical and scientific debate: whether bodily experiences follow emotion or the other way around
Emotions Impact Heart Health and Vice-Versa
Emotional states have an impact on how the body operates. Anxiety and fear, for example, can cause the heart to beat more quickly. Nevertheless, whether the opposite is true - that an increase in heart rate causes anxiety or terror responses - remains unknown. One of the primary difficulties in examining the impact of heart rates on emotions was a lack of a suitable tool for accurately controlling the heart rate without creating adverse effects or introducing confounding factors. Karl Deisseroth and colleagues created a non-invasive optical pacemaker that uses light signals to target cardiac muscle cells and can raise mice heart rates to 900 beats per minute (bpm) from 660 bpm. The researchers discovered that an optically induced elevation in heart rate increased anxiety-like behaviors and dread in mice, but only in potentially dangerous circumstances. The authors scanned the brain for changes in activity to investigate the underlying causes of this action. The posterior insular cortex, a part of the brain that receives and processes signals from all over the body, was identified as a potential mediator for the anxiety-like and apprehensive behaviors generated by elevated heart rates. Furthermore, it was discovered that inhibiting the posterior insula cortex reduced the anxiety-like behaviors caused by optical cardiac pacing.Heart Rate Affects Emotional Behavior
“This is an unequivocal demonstration that, at least in mice, heart rate can affect anxiety, and can probably influence other emotional behaviours, too,” write Yoni Coudec and Anna Beyeler in an accompanying News & Views article. Further research is needed to determine the long-term impact of elevated heart rates on the brain and affective behaviors, as well as to investigate potential translational and therapeutic uses of these results.
Resting Heart Rate
Heart rate implies the number of heartbeats a person does have per minute. It is also commonly known as the pulse. Please note that having a lower resting heart rate is generally a sign of good health. A healthy resting heart rate will vary from person to person. For most people, a target resting heart rate is usually between say 60 and 90 beats per minute (bpm).

Heart Rate and Heart Rhythm
Normal heart rate and rhythm can be measured by checking pulse on the wrist and evaluated with an electrocardiogram. Myths about heart rate can lead to anxiety.

Postural Orthostatic Tachycardia Syndrome (POTS) - Causes, Symptoms, Diagnosis, Treatment and Prognosis
Postural Orthostatic Tachycardia Syndrome (POTS) is a circulatory disorder which is characterized by an increase in heart rate or tachycardia and is treated by medicines, diet, exercise and lifestyle changes.
