The fight-or-flight stress response begins in the emotional brain with the panic button amygdala. This threat processor has been on overdrive during the pandemic. When the amygdala detects a threat, it signals the release of stress hormones, including adrenaline.
In a brain mapping study, researchers have discovered a complex network of brain cells that is involved in the stress response and adrenaline release. They found that the motor areas of the brain, those that control the body’s core, also connect to the adrenal glands. By revealing this direct connection between the core and the stress response system, this research supports other evidence that strengthening your core has a positive impact on stress. Researchers theorize this may explain why yoga and Pilates are successful stress management practices.
Takeaway: Consider strengthening your core to help with stress management. This is a great time to start yoga or Pilates, or to do planks between Zoom meetings (Hat Tip to my Teaching Assistant for this idea).
