Enjoying time with friends, family and colleagues is a continuation of how we evolved and survived. The tribes Homo Sapiens evolved in fostered a sense of community that continues to have a biological imprint on us. And as much as we try, we cannot deny our biology.
These social connections provided us safety in numbers. In turn our amygdala can neurocept safety in the internal and external environment, allowing the mind-body system to exist in its parasympathetic nervous system (PSNS); our ‘rest and digest’ system. This system allows the mind-body system to function optimally and promote wellbeing.
The other branch of our nervous system is the sympathetic nervous system. This is our ‘fight or flight’ system. While this system is extremely useful, if we exist in it for a long period of time, our long-term functioning is inhibited and both our physical and mental health will be compromised.
Quality social interaction and connection promotes the PSNS. Research has shown that social connection reduce inflammation, improves immune function, strengthens the cardiovascular system and can protect you against anxiety and depression. Loneliness, conversely, has been associated with increased inflammation, poor immunity and an increased risk of dementia, stroke and heart attacks.
Social connection promotes the parasympathetic system by:
Producing a hormone called oxytocin, which helps counteract cortisol (a stress hormone) and switches on the PSNS. ‘Feel good’ neurotransmitters such as dopamine, serotonin and endorphins are also released, which also work against stress hormones.
Improving emotional regulation. In addition to providing our mind-body system with a sense of safety, when we talk through our emotions and experiences, we are provided with a sense of validation and comfort, which helps regulate our emotions. Where we can regulate our emotions, we can shift between our SNS and PSNS more easily.
Increasing our heart rate variability (HRV). This is a measure of the variation in time interval between successive heartbeats. A higher HRV is generally associated with flexible functioning of the nervous system, meaning, again, we are able to move into our PSNS more easily.
Turning on the social engagement system. According to the Polyvagal Theory, social interactions and connections activate the ‘social engagement system’. This, again, helps us reside in the PSNS.
So, work on your relationships and prioritise spending quality time with friends, colleagues and family. You’ll feel good, inside and out.
