ADHD and the Nervous System: A Biological Regulation Guide
ADHD, stress responses, and biological calming techniques from the perspective of polyvagal theory and the autonomic nervous system.
The Nervous System's Safety Scan: Neuroception
According to Stephen Porges, the founder of Polyvagal Theory, our autonomic nervous system constantly scans the environment for safety without our conscious awareness. This process is called Neuroception. In individuals with ADHD, this scanning mechanism is hypersensitive; the slightest sensory overload or cue of rejection can immediately trigger the nervous system into "fight or flight" (Sympathetic) or "freeze/shutdown" (Dorsal Vagal) modes.
As noted by the @adhd.ahead platform, procrastination and inaction in ADHD are often not laziness, but a state of Dorsal Vagal freeze (ADHD Paralysis) entered by the nervous system to protect itself. Recognizing these biological states of the nervous system allows us to develop self-compassion.

Somatic Regulation Strategies
Trying to calm down mentally usually does not work when the nervous system is on alert, because the top-down flow of information is cut off. Instead, we must use bottom-up signals going from the body to the mind. Somatic (body-based) interventions step in here.
Stimulating the vagus nerve (increasing vagal tone) allows the heart to calm down. Slowed breathing exercises, washing the face with cold water, gentle swaying, or stretching send a "we are safe" signal to the brain, helping the mind return to a focused state (Ventral Vagal).
