What happens with constriction and compression of blood vessels? How to help the vessels and nerves work normally?

The constriction causes stagnation of venous blood. The veins swell, the capillaries expand, and therefore the finger becomes first red and then purple. Indeed, oxygen-rich arterial blood almost does not enter, and the blood in the capillaries becomes dark, venous. From the capillaries, the output of tissue fluid is enhanced. She can not leave the lymphatic vessels: constriction interferes. Tissue fluid accumulates in the intercellular space, and the finger again changes color: it becomes white. The finger is tight to the touch. Excess tissue fluid compresses blood vessels and nerves. This disrupts their work. To make sure of this, try to touch a surface with your finger. The touch is weak: the finger has become “cottony.” Oxygen starvation begins, and the finger perceives irritations worse. Tingling is a sign of oxygen deficiency. The nervous system needs oxygen, skin receptors cannot work without it. Remove the ring and massage your finger from the tip to the base. Venous blood will go to the heart, and light arterial blood rich in oxygen will take its place. The sensitivity of the finger will quickly recover, and it will return to normal. If you trace the improvement of people’s clothes, you can see how gradually the fashion designers refused to constrict. Tight corsets have long since sunk into oblivion, without which no secular lady of the 19th century could do without, stockings with elastic bands were replaced by pantyhose, even trouser belts were replaced by suspenders. Due to this, blood circulation and lymph outflow from cells are not disturbed.
