Vagal tone and human connections
Remarkably, people with higher vagal tone are more flexible across a whole host of domains — physical, mental, and social. They adapt better to their ever-shifting circumstances, albeit completely at nonconscious levels. Physically, they regulate internal bodily processes such as glucose levels and inflammation more efficiently. Mentally, they’re better able to regulate their attention and emotions, even their behaviour, and navigate interpersonal connections. By definition, then, they experience more micro-moments of love. It’s as though the agility of the conduit between their brains and hearts — as reflected in their high vagal tone — allows them to be more agile, attuned, and flexible as they navigate the ups and downs of day-to-day life and social exchanges. Indeed, this is what doctoral student Bethany Kok and I have found: compared with people with lower vagal tone, those with higher vagal tone experience more love in their daily lives, more moments of positivity resonance.
