Satisfaction with life and religiosity  

Consistent with other studies, the researchers found that older individuals were more likely to participate in religious activities and had a greater sense of satisfaction with life. Studies have shown that older, more religious adults engage more in charity and volunteer work and express greater life satisfaction.

The researchers found that a larger oxytocin response to the video stimulus was associated with a greater sense of satisfaction with life, participation in religious activities, and increased levels of empathy and gratitude.

Study limitations

The authors cautioned that the study only correlates oxytocin release and prosocial behaviors and other traits. The findings are especially relevant since there is a bidirectional relationship between oxytocin release and prosocial behaviors, with engagement in prosocial behaviors associated with a subsequent increase in oxytocin levels.

The authors also noted that the study involved a small number of participants residing in California. Hence, more research involving a larger number of participants representing the broader demographic needs to be conducted.

Intranasal oxytocin

Other studies also suggest that using intranasal sprays to deliver oxytocin can improve mood and cognitive function, especially in older men. Although there is an interest in the therapeutic use of intranasal oxytocin, the effects of oxytocin vary by context and among individuals.

Dr. Natalie Ebner, a neuroscientist at the University of Florida, noted in a lecture, “There is a lot of evidence that oxytocin doesn’t always work the same way. It depends a little bit on what kind of situation you are in, if it’s a positive social situation it does one thing, if it’s a hostile situation suddenly it increases aggressivity. So there are a lot of interesting manipulations we can do by looking closer at contextual factors and we’re starting to see a lot is that not everyone responds in the same way.”
