• Activation of the Parasympathetic Nervous System:

  • Yoga emphasizes deep breathing and mindful movements, which activate the parasympathetic nervous system (PNS) or the "rest and digest" system.

  • This counteracts the sympathetic nervous system (SNS) or the "fight or flight" response, reducing stress levels.

• Vagal Tone Improvement:

  • Practices like diaphragmatic breathing stimulate the vagus nerve, promoting relaxation and reducing anxiety.

Research Insight:
A study published in Frontiers in Human Neuroscience demonstrated that yoga enhances vagal tone and heart rate variability, both indicators of reduced stress.

• Yoga has been shown to lower cortisol, the primary stress hormone. Elevated cortisol levels can negatively impact physical and mental health.

• Studies reveal that consistent yoga practice reduces cortisol levels, improving overall stress management.

Research:
A meta-analysis in Psychoneuroendocrinology found that yoga interventions lead to significant reductions in cortisol, especially in women experiencing high stress.

• Yoga promotes the release of neurotransmitters that improve mood and reduce stress:

  • GABA (gamma-aminobutyric acid): Increases with yoga practice, reducing anxiety.

  • Serotonin and Dopamine: These “feel-good” chemicals are boosted during yoga, enhancing emotional well-being.

Research:
A study in the Journal of Alternative and Complementary Medicine found that yoga practitioners had significantly higher GABA levels compared to those who walked for exercise.

• Chronic stress is linked to increased levels of inflammation in the body, which can exacerbate health issues.

• Yoga reduces pro-inflammatory cytokines, helping to combat stress-induced inflammation.

Research:
A study in Psychosomatic Medicine found that yoga practitioners exhibited lower levels of inflammatory markers like IL-6 after stressful events.

• Yoga incorporates mindfulness, encouraging individuals to focus on the present moment and detach from stress-inducing thoughts.

• Mindfulness practices improve emotional regulation and reduce rumination.

Research:
A review in Mindfulness reported that yoga-based mindfulness programs significantly decreased symptoms of anxiety and depression.

• Chronic stress often disrupts sleep patterns, leading to fatigue and emotional distress.

• Yoga, particularly restorative and nidra practices, improves sleep quality by calming the mind and body.

Research:
A study in Sleep Science found that yoga improved sleep efficiency and reduced sleep latency in individuals with insomnia.

• Yoga fosters self-compassion, acceptance, and emotional resilience, equipping individuals to better handle stress.

• Group yoga sessions can also provide a sense of community and reduce feelings of isolation.
