In the past history about the numbness of the face against the background of excitement we discussed the action of adrenaline and blood flow in the head. Now it's the turn of calcium with phosphorus.
Calcium
When scientists studied various psychos and recorded complaints of numbness of the face with goose bumps or needles on the skin, it was suggested that the level of calcium in the blood was falling.
When an anxious person panics, they breathe frequently and deeply. Because of this, carbon dioxide is quickly eliminated from him, and less calcium may become in the blood. Well, because of the calcium drop, sick people have many different sensations.
Scientific research was screwed up under this business, but they gave conflicting results. Someone swore that calcium in the blood directly falls, while someone disagreed and said that nothing of the kind was observed in his research.
Nobody wanted to give in, and as a result, they agreed on a clever compromise, when the total calcium in the blood may not change, but the amount of ionized calcium decreases.
In our blood, about half of the calcium floats freely and the same amount is bound to blood proteins. Protein-bound calcium does nothing. It is hidden there.
So a nervous person often breathes and exhales carbon dioxide. Usually, when carbon dioxide is dissolved in water, it floats there in the form of carbonic acid. Therefore, if carbon dioxide is expelled from the blood, then there will be less acid in the blood.
If the balance of acid and alkali is disturbed in the blood towards the prevalence of alkali, then calcium begins to better bind to proteins. It hides from alkali inside proteins. That is, there will be less free floating ionized calcium in the blood. And when this happens, some muscles begin to cramp. Including the muscles on the face. It seems to people that their face is going numb. At the same time, the analysis for total calcium will not show anything.
Phosphorus
Phosphorus has a similar story. Only from alkali, it hides not in proteins, but inside the cells. Therefore, there is less phosphorus in the blood. If there is little phosphorus in the blood, then different organs begin to suffer. Including the brain. Something happens inside the affected brain that we experience as facial numbness. This is another reason.
It is believed that phosphorus does not itself jump into the cells, but insulin roughly drives it there.
When we freak out, adrenaline and all kinds of stress hormones are released. They know how to raise our blood glucose levels. This is such a defensive reaction in case you have to save yourself from someone. We discussed this in history about acetone in children.
So glucose in the blood rises, and a lot of insulin is released into this glucose. Insulin drives glucose into cells, and phosphorus gets there under the hot hand.
Exactly the same story happens with starving people when they decide to get out of hunger and overeat. Their level of phosphorus in the blood drops, and it becomes bad. We discussed this in an article about hunger.
In short, everyone can choose a version to their liking, but the result is the same - from the excitement, goose bumps begin to run.
