Do you often use nicotine or smoke while you are working or writing? If yes, you should read this article to know the effects of nicotine on the brain. I am sure it's not good.
One of the major components of a cigarette is nicotine. It can cause a series of side effects on the human body. Apart from being known as a carcinogen, it is also considered to be addictive. While there are significant studies and restrictions on the use of dependency drugs, no such ban is placed on cigarettes. This makes it all the more dangerous since you can get it from anywhere.
Getting Dependent on Nicotine
It takes approximately ten to twenty seconds for nicotine to reach your brain cells through your blood stream. It is then that it binds to your neural receptors and interferes with the neural activities of the brain. These neurons, when triggered on a larger scale, make its way to the basal ganglia of the brain. Now normally this is just another area of the brain, but what makes it special is that it monitors the brain's motivation and reward system.
Once the nicotine-bonded neurons enter this area of the brain, they release a chemical called dopamine. This chemical is responsible for making humans feel a sense of satisfaction and pleasure. This particular area of the brain is also responsible for our survival instincts and hence, the nicotine makes its way into the list of things you need to survive.
Every time nicotine makes its way to your brain, the idea of it being a positive aspect increases to a point where there is no question left about its positivity to your body. Before you know it, you are dependent on a drug that you swore you could leave anytime. Furthermore, your body starts to develop tolerance against the act and soon, you require more and more nicotine to make you feel satisfied.
What does nicotine do to you in the long run?
Once the nicotine dependency is completely formulated inside a smoker's body, the addiction worsens. With the passage of time, the neural pathways that initially made way for nicotine start linking smoking to more and more actions performed by the human body. For example, various individuals feel that they cannot digest their food without having a smoke first.
Before you know it, your body starts relating other aspects of the world to smoking. Thus, a bad day at work might mean you need a smoke.
Similarly, with the passage of time, the number of these neural pathways increase and the answer to everything in life becomes smoking. As they continue to grow in both strength and number, so does your dependency on cigarette.
It is not just your need for cigarettes that increases. It is also the amount of cigarettes needed to stimulate a similar effect on the body.
To summarize things up, using a box of cigarette a day can cause at the minimum advanced chronic brain diseases.
