My understanding is that pupils naturally dilate and contract in a rhythm that is like the breath (pupils "breathing"), and that it is an indicator that you are neurologically integrated. (Note: someone researching the effectiveness of Rapid Eye Technology found that 100% of individuals in the prison they studied were NOT neurologically integrated, i.e., their pupils did not "breathe." Their protocol for catalyzing that integration required gazing into the prisoners' eyes, from a distance of approx. 7-9", with pure, unconditional love -- typically that given by new mothers to their infants, especially during feeding. At a certain point the pupils "moved," (think of "jump-starting"), and began to "breathe" -- that is, to rhythmically dilate and contract, without the influence of light. The researchers posited that neurological integration is a precursor for acting in the world from a place of Connection, rather than from a place of Disconnect. It you think about it, that's a profound notion.
No it causes them to dilate (vasodilation)
Veins contract and expand in response to blood pressure.
It is possible to dilate without bloody show or losing your mucus plug.
It is relatively simple for round shaped sphincters to either dilate or contract.
During exercise your muscles need more energy from respiration in order to contract. So your heart beats faster and the arteries supplying the muscles dilate (widen)
To contract or dilate in order to increase/decrease blood pressure (and obviously blood supply)
dilate
sympathetic stimulation causes the dilator muscle to contract and sphincter muscle to relax, as a result expanding the pupil.
He continued to dilate on the subject for what seems forever. or Darkness and light will cause your eyes to dilate.
Not necessarily. Eyes dilate for many reasons.
Can steroids cause pupils to dilate
Light Pupil Dilate was created in 2001.
