Key Takeaways
• People who laugh less than once a month have significantly higher mortality risk.
• Laughter improves vascular function and pain tolerance.
• Play is a form of nervous system regulation.
Hook
We track biomarkers and habits for predictors of longevity, and yet, no one tracks how often we laugh.
Context
I can tell you my resting heart rate. I cannot tell you how many times I laughed last week. But most people can see the nature of my heart by the kindness of my face, my words, and my smile. Laughter paves the way for the gentleness of my heart to be shared and shown freely.
The research literature shows something quite startling:
1. People who laugh less than once a month have nearly double the mortality risk of those who laugh weekly.
2. Older adults who laugh almost every day have lower rates of functional disability.
3. Watching something genuinely funny improves vascular function.
4. Social laughter improves pain tolerance.
This is not about mood; it’s about longevity. It’s a direct correlation between the dispositions our hearts and our own cardiac morbidity and mortality.
Insight
When we laugh:
· Internally:
o Blood vessels dilate
o Stress hormones drop
o Endorphins rise
o Muscles relax
o Parasympathetic nervous system activation shifts us out of threat mode and into relaxation and flexibility
· Externally:
o Nothing changes.
o Circumstances are undisturbed
o Responsibilities stay the same
o Bills remain
o Diagnoses stand
o Conflicts persist
But the dispositions of our heart become more willing, flexible, and adaptable. Laughter is not about escape; it’s physiological nurturance. Adaptable systems overcome and endure.
Application
If laughter were a health metric, how consistent would you be?
Reflection Question
What would change if you treated laughter like medicine instead of an afterthought?
