Why Do We Get Pee Shivers?

Have You Ever Had a Pee Shiver? (a sudden full body shiver upon first morning urination) Why do we get them? "No one knows for certain what the specific trigger for the shivering is," says Dr. Anish Sheth, former director of the gastrointestinal motility program at Yale Medical School and author of "What's My Pee Telling Me?" Dr. Cassone's Theory:

1. The body enters parasympathetic nervous system regulation to initiate pee pee mode.

2. A drop in ADH (anti-diuretic hormone) from the pituitary and a drop in aldosterone from the adrenal glands allow for voiding of the extra amount of urine accumulated all night.

3. The hormone switch combined with the rapid loss of a large amount of fluid cause two phenomena: ► a drop in body temperature (urine is 98.7 degrees) ► a drop in blood pressure

4. The last point causes a switch (midway to end of pee) to sympathetic nervous system mode (fight or flight).

5. To regain blood pressure, nor-epinephrine is released from the adrenal glands to vaso-constrict the blood vessels and an involuntary shiver occurs to jump start heat generation internally.

If I'm right, then slowing down the loss of urine may prevent the shiver. This can be done by interrupting the urination in intervals of up to 15 seconds to allow for the body to incrementally adjust to the bladder change.

Have fun experimenting :)
