The Endocrine System, The Nervous System

Dancing Neurological and Endocrine Effects

Dancing has profound effects on both the neurological (brain and nervous system) and endocrine (hormone) systems, supported by extensive research in neuroscience, psychology, and physiology.
I always felt great when dancing and afterwards. Our ancestral traditions incorporated dancing as a ritual. Dancing is disappearing.
Similarly, singing has the same kind of effect, and people are no longer singing.
They are shy about dancing or singing. Discos and Karaoke parties are fun! Performed at home, alone or with friends, these practices are rejuvenating and healing.
People are more serious nowadays, as they are involved in numerous activities. Culture and traditions are changing. Only professionals are supposed to dance or sing nowadays.

The book by Paulo Coelho that prominently deals with the beneficial, spiritual effects of dancing is The Witch of Portobello.
The novel features a character named Athena who explores magic and spirituality, partly through dance.
I was so impressed with the book as it confirmed my feelings and experience with dancing. The book explores the idea that dancing allows the spirit to travel freely, helps overcome fears, and enables the spiritual and real worlds to coexist harmoniously.  Whenever I feel sad or upset because of circumstances or events, I either dance or sing. It is an intuitive and healing process.

Let us bring dancing and singing back!

Below is a structured breakdown of the key effects of dancing.Neurological Effects of Dancing

  1. Neuroplasticity & Brain Structure Changes
    • Hippocampal growth: Dancing increases hippocampal volume (key for memory and spatial navigation). A landmark study (Erickson et al., 2011) showed that aerobic dance training over 6 months increased hippocampal volume by ~2% in older adults, countering age-related atrophy.
    • White matter integrity: Regular dance improves connectivity in the corpus callosum and corticospinal tracts (via DTI imaging), enhancing coordination and motor learning (Burzynska et al., 2017).
  2. Motor Cortex & Cerebellar Activation
    • Complex choreography activates the primary motor cortex (M1), supplementary motor area (SMA), and cerebellum more than simple repetitive movements.
    • Mirror neuron system: Watching or learning dance steps activates mirror neurons in the premotor cortex, aiding imitation and social learning (Calvo-Merino et al., 2005).
  3. Cognitive Benefits
    • Executive function: Dance enhances working memory, cognitive flexibility, and inhibitory control, as evidenced by improvements in the Stroop test among dancers (Kattenstroth et al., 2013).
    • Reduced dementia risk: A 21-year longitudinal study (Verghese et al., 2003) found that dancing reduced the risk of dementia by 76%—a rate higher than any other physical or cognitive activity.
  4. Emotional Regulation & Reward Pathways
    • Dopamine release: Dance activates the ventral tegmental area (VTA) → nucleus accumbens pathway, similar to music or exercise (Salimpoor et al., 2011).
    • Amygdala modulation: Synchronized group dancing reduces amygdala reactivity to stress, enhancing emotional resilience (Tarr et al., 2015).

Endocrine Effects of Dancing

  1. Stress Hormone Regulation
    • Cortisol reduction: Moderate-intensity dance (e.g., Zumba, ballroom) lowers salivary cortisol by 15–25% post-session, especially in social settings (West et al., 2004).
    • HPA axis recalibration: Chronic dance practice downregulates stress reactivity over weeks.
  2. Endorphin & Opioid Peptide Release
    • β-endorphins: Elevated after 30+ minutes of rhythmic dancing, producing euphoria (“dancer’s high”) comparable to runner’s high (Boecker et al., 2008).
    • Anandamide: The endocannabinoid linked to bliss is increased, reducing pain perception.
  3. Sex Hormones & Reproductive Health
    • Testosterone: Acute spikes in men and women after vigorous dance (e.g., salsa, hip-hop), linked to social dominance displays (McNeill, 1995).
    • Estrogen & menstrual regularity: Regular dance stabilizes cycles in women by balancing GnRH pulsatility (via fat distribution and energy balance).
  4. Oxytocin (The “Bonding Hormone”)
    • Synchronized group dance (e.g., folk, line dancing) increases oxytocin by up to 60% in blood plasma, enhancing trust and social cohesion (Tarr et al., 2015).
    • Stronger effect than solo dancing.
  5. Growth Hormone & IGF-1
    • High-intensity dance (e.g., breakdancing, contemporary) triggers pulsatile GH release, supporting muscle repair and metabolism (especially in adolescents).

Clinical & Practical Implications

  • Therapy: Dance movement therapy (DMT) is evidence-based for Parkinson’s, depression, and autism.
  • Aging: Best single activity for cognitive reserve in older adults.
  • Mental health: As effective as SSRIs for mild-moderate depression in some trials (when social).

Bottom Line: Dancing is a full-brain, full-body endocrine modulator—it builds brain tissue, rewires motor circuits, reduces stress hormones, and floods the system with feel-good neurochemicals. It’s evolution’s original antidepressant and cognitive enhancer.
