The nicotine coming in with smoke is similar in structure to acetylcholine, a substance that the body produces on its own. Thanks to acetylcholine, the nervous system and the brain work well. This substance provides transmission of nerve impulses, which helps in the work of all body systems, maintains a good tone of blood vessels.

If you get into the body of a nicotine smoker, it will affect the parts of the brain that are particularly sensitive to the action of acetylcholine. In the smoker, the production of this substance by the body is reduced, the nerve cells are less sensitive to it. The longer the intake of nicotine occurs, the less acetylcholine is produced.

As nicotine-dependent people constantly have a small poisoning, the body not only adapts to the effects of toxic substances, but also adapts to extract from it everything that is necessary, after natural production slows down. After stopping smoking, a person needs some time to return to normal.

The reason for dizziness is often the lack of oxygen - this condition occurs for the following reasons:

  1. Changes in vascular tone - nicotine, when ingested, acts on the blood vessels, narrowing them and causing a spasm of the capillaries. The tone of the vessels drops sharply after giving up cigarettes, blood pressure drops, the head begins to spin.
  2. The concentration of oxygen in the blood increases. A person who smokes has less oxygen in the bloodstream than a non-smoker, because his place is occupied by molecules of carbon dioxide. The body actually is in conditions of oxygen starvation and gets used to it so much that the increased supply of oxygen into the blood causes nausea or dizziness due to oversaturation.
  3. There is a so-called withdrawal syndrome. Nicotine is not a prohibited substance, but it should be attributed to drugs. When there is a shortage in the body, processes similar to those that occur during narcotic withdrawal are caused. This is due to the ability of nicotine to replace acetylcholine almost completely. A person who quits smoking is dizzy or has a headache due to a decrease in the usual substances in the blood. Dizziness in this case can be considered as the first of the signs of the beginning of cleaning the body.
  4. Changes in the psychological state. Most people who quit smoking are in a state of high nervous excitability, are not able to relax properly, often have problems with sleep. This is due not only to the reaction to the lack of nicotine, but also to a variety of problems of the psychological plan, previously successfully solved with smoke breaks. The cause of the headache may be the release of adrenaline and other stress hormones into the bloodstream, an unceasing nervous tension, and a lack of adequate rest.
