Ever wondered what happens when you take this deep cravings on a cigarette. You get a familiar leap in the lungs, a stream of relief, clarity, ah! factor. But what does nicotine do in you? Read on and find out.
When you draw this first smoke, it passes by your larynx, slides down the esophagus and goes through two bronchi to the bronchioles that make up your lungs. Here he meets the alveoli, small sacs, where the oxygen that you breathe is absorbed by hemoglobin in the blood.
Alveoli - a beautiful creature of nature. They provide an absorbing surface for oxygen with an area 90 times the surface of the skin. When tobacco smoke enters the alveoli, nicotine and other chemicals are quickly absorbed into the bloodstream, where it quickly penetrates your brain and throughout the body.
Less than ten seconds after taking this layer, nicotine enters the brain, its main sphere of influence. Nicotine is a psychoactive drug, meaning that it affects the chemistry of the brain. He does it in different ways, one of which is particularly insidious. This leads to the release of dopamine, a naturally occurring chemical in the body. Dopamine works on the path of rewards, which lead to a pleasant feeling that we get after doing something good. In this case, nicotine deceives the neurons in the brain to make us feel like a good factor for doing something dumb - smoking cigarettes.
Meanwhile, nicotine causes adrenaline adrenaline prolapse, which causes an increase in heart rate, blood pressure, and glucose release. At the same time, nicotine says that the pancreas reduces insulin, which leads to an increase in blood sugar levels. Your heart rate increases by 30%.
All of these reactions in the body combine to form the rush in which smokers live.
As this happens, nicotine causes the stomach, increasing its acid secretions. When many smokers skip a meal, it has many unpleasant consequences, such as a stomach ulcer.
But the worst thing is that nicotine does not come alone. He brings more than 4,000 cohorts ready to damage your body. While nicotine works on your brain and keeps you addicted, other chemicals in the smoke are busy destroying other parts of your body. These include tar, arsenic, deadly poison, used to make rat poison, ammonia an ingredient in floor cleaning products and butane, which you will find in your cigarette lighter
Let's give some examples. Under the onslaught of smoke, the walls between the bags of the alveoli collapse. Once they are destroyed, they never grow. This can lead to chronic conditions such as emphysema. Smoke also paralysis cilia, small hairy sweepers that clean your lungs. When you need protection most of all, your cleaning products become incompetent.
In addition, tobacco smoke chemicals damage the walls of blood vessels. This allows plaques to grow faster, increasing the risk of heart disease by accelerating arteriosclerosis.
Nicotine has a short but destructive life in the human body. With a half-life of one hour, he was almost gone in six hours. Except that the average smoker has lit ten times over this period, repeating a destructive cycle.
About 80 percent of nicotine is processed by liver enzymes, and most of the rest is filtered by the kidneys.
Many other chemicals in tobacco smoke are more dangerous than nicotine. But nicotine is a master, without which they will never enter your body.
Recognizing nicotine for what it is is a key step to conquering tobacco addiction.
