Effects of Nicotine on the Brain

At a Glance:
When nicotine enters the body, it instructs the brain to release a hormone called adrenaline. Often called the 'fight or flight' hormone, adrenaline causes an increase in heartbeat, raises blood pressure and causes irregular or shallow breathing.

Apart from all these general effects, adrenaline also instructs the brain to release glucose into the blood. This also negatively affects the functioning of one other hormone known as insulin. This makes smokers prone to hyperglycemia or diabetes. This happens because of the disturbance of the two hormones which means that a smoker is likely to have more sugar than desired in his blood.

In present day and age, smoking is something so widespread that it will only be fair to regard it as a socially acceptable norm. Tobacco has always been smoked in one form or another for what seems like an eternity and as the years progressed, it appeared in the form of cigarettes. Smoking has always been a controversial issue, one that has been raising eyebrows ever since its adoption as an addiction.

The reasons people start smoking are entirely different from the ones that prevent them from giving up this life threatening habit. Research has concluded and it has also been medically proven that smokers put quitting smoking next to impossible as cigarettes contain nicotine which is an exceedingly addictive drug.

Some physicians even claim that nicotine can be as addictive as cocaine or heroin which leaves no doubt as to why individuals fail to quit it once they get started. While it is obvious that the nicotine in cigarettes makes you vulnerable to certain health hazards, the way it affects the brain and other organs remains a mystery.

Physicians believe that the way nicotine can make a smoker feel depends on the quantity and frequency of intake. Based on how much and how often you smoke, one can restrain the influence of nicotine on the brain and body.

When nicotine enters the body, it instructs the brain to release a hormone called adrenaline. Often called the 'fight or flight' hormone, adrenaline causes an increase in heartbeat, raises blood pressure and causes irregular or shallow breathing.

Apart from all these general effects, adrenaline also instructs the brain to release glucose into the blood. This also negatively affects the functioning of one other hormone known as insulin. This makes smokers prone to hyperglycemia or diabetes. This happens because of the disturbance of the two hormones which means that a smoker is likely to have more sugar than desired in his blood.

In addition, nicotine is also believed to reduce one’s appetite. Again, diabetes can be a feasible explanation. When the brain receives signals regarding the increased blood sugar levels, it translates it into satiation, hence, the smoker experiences loss of appetite.

Nicotine also influences one’s metabolic rate. This means that if you are making efforts for weight loss, nicotine will accelerate the process. Even if nicotine helps burn calories faster, you can never secure the desired health benefits by using it for weight loss.

What makes nicotine all the more menacing for the heart is the fact that is that it constricts the arteries. It is a medically proven fact that nicotine causes an increase in levels of LDL, often termed as bad cholesterol. So, if you are consuming nicotine in one form or the other, you are actually at a higher risk for stroke and other heart diseases.

In short, nicotine is the magnet that compels smokers to stay hooked to it. It may make smokers feel good for the time being but in the long run, it can affect the brain and body devastatingly. In order to steer clear of any undesired and menacing health issues, throw nicotine out of your life once and for good.
