This is a segment from my Polyvagal One Pagers free PDF in my File Share. There are more short lessons on the fundamentals of the Polyvagal Theory in that PDF as well. These are useful for your own short lessons, classes you might teach or handouts you might give out at a seminar or workshop.
The flight and fight system is the sympathetic branch of the autonomic nervous system.
The flight and fight system is important for optimizing the body for evasion or aggression. It
repurposes resources because some functions are not necessary during moments of danger. For example, chewing is not necessary when in danger, so saliva is not produced and the mouth goes dry. The body needs to stay at a higher level of energy, so breathing becomes shallow and heart rate increases. These changes are intended to be temporary; for small bursts when in times of danger.

Thoughts become: concrete, evaluative, focused on the past or the future
Feelings of: danger, tenseness, anxiety, anger
Able to: mobilize, escape, avoid, use aggression
Unable to: self-regulate, provide co-regulation opportunities, think critically, weigh options, be
