Science & Health Benefits of Belief in God & Religion | Dr. David DeSteno

Episode 243 Aug 25, 2025 2h 24m 14 insights
My guest is Dr. David DeSteno, PhD, a professor of psychology at Northeastern University. We discuss science, God and religion, including what science can and can’t reveal about the existence of God and where religious faith and science do and do not align. We also discuss why questions about life’s origins, miracles and the afterlife have persisted across time. Dr. DeSteno explains how religious rituals cause meaningful improvements in mental and physical health and how prayer and gratitude can markedly reduce stress, increase honesty and compassion and buffer against loneliness and despair. Finally, we explore what distinguishes religions and mission-based communities from cults, and we discuss the role that communities such as 12-step and Burning Man play in modern life.

Actionable Insights

1. Engage in Regular Meditation

Practice meditation consistently to boost compassion, reduce anger, improve executive control, lower blood pressure, and alleviate suffering.

2. Practice Formal Prayer

Recite formal, formulaic prayers to physiologically reduce stress by lowering respiration rate, increasing exhalation duration, boosting vagal tone, and decreasing cortisol, fostering a sense of safety.

3. Cultivate Daily Gratitude

Make a habit of counting your blessings or expressing gratitude daily, as this practice promotes prosocial behaviors like honesty, patience, generosity, and helpfulness.

4. Join a Religious Community

Actively participate in a religious community to engage in shared practices like singing, praying, and moving in unison, which strengthens social bonds, increases empathy, and provides health benefits beyond general community involvement.

5. Contemplate Death Mindfully

Regularly and briefly contemplate your own mortality, not morbidly, to reorient your values towards relationships, service, and legacy, which are key drivers of happiness at any age.

6. Foster a Relationship with God

Cultivate a personal belief in and relationship with God to reduce feelings of loneliness, providing a constant sense of support and companionship.

7. Surrender to a Higher Power

When facing overwhelming challenges or addiction, practice surrendering control to a higher power; this involves doing your best, then trusting for help, which significantly reduces stress and anxiety.

8. Reduce Self-Focus in Grief

During periods of intense sadness or grief, consciously reduce self-focus (e.g., by avoiding excessive grooming or elaborate clothing) and cover mirrors, as these actions can help mitigate the intensity of negative emotions and aid in healthy bereavement.

9. Consolidate Positive Grief Memories

When grieving, make an effort to consolidate positive memories of the deceased, as this practice is a significant predictor of moving through grief successfully.

10. Embrace “Do, Then Understand”

Adopt the principle of “naish v’nishma” (we will do, and then we will understand) by engaging in spiritual or beneficial practices first, even without full logical comprehension, as understanding and benefits often emerge through the act of doing.

11. Explore Diverse Spiritual Paths

Be open to exploring different religious or spiritual practices and traditions to discover what genuinely resonates with you and improves your life, as it’s acceptable to sample and question.

12. Ensure Safe Psychedelic Use

If considering psychedelics, prioritize a supremely safe environment and, ideally, the presence of a guide or therapeutic support to navigate the experience and prevent potentially negative outcomes.

13. Combine Belief with Practice

Integrate creedal or belief elements with physical and communal practices, as this synergistic approach can lead to a greater magnitude of positive effects compared to practices alone.

14. Avoid Excessive Distractions

Be aware of and limit behaviors that serve as mere distractions (e.g., endless scrolling, mindless eating) to avoid addictive patterns and to confront underlying feelings of loneliness or existential fears.
