A person's heart rate and blood pressure can change when they face sudden stress.  This is known as cardiovascular reactivity.  Some people believe that faith and spirituality can help manage this stress.  However, research on this topic has mixed results.  Some studies show that strong beliefs can help, while others suggest it might not always be helpful.

To make sense of this, a group of researchers looked at many studies on the topic.  They found twelve studies that fit their criteria.  Most of these studies showed that people with strong religious or spiritual beliefs had better cardiovascular reactivity.  This means their heart rate and blood pressure did not spike as much when faced with stress.  This was especially true for people who had deep, personal beliefs and found meaning and purpose in life through their faith.

However, it's not all positive.  Three studies found that people who struggled with their faith or spirituality had worse cardiovascular reactivity.  This means their heart rate and blood pressure spiked more when stressed.  This shows that struggles with faith can have a negative impact on health.

One big problem is that these studies did not always clearly define what they meant by religiosity and spirituality.  Sometimes, they were used interchangeably, which can lead to confusion.  Future research should clearly define and separate these two concepts.  This way, we can better understand how each one affects cardiovascular reactivity.

It's also important to note that no study has controlled for one factor when examining the other.  For example, no study has looked at spirituality while controlling for religiosity, or vice versa.  This would help us understand if one factor is more important than the other.

In conclusion, faith and spirituality can have both positive and negative effects on how the heart reacts to stress.  More research is needed to fully understand this complex relationship.  For now, it's clear that struggles with faith can be harmful, while strong, personal beliefs can be beneficial.
