If you drink regularly, you tend to ignore the immediate effects of alcohol on the brain as you would have developed a tolerance for it. As a result, you may often drink without realizing the ill effects as alcohol does not let you know. Such tolerance is metabolic – the liver breaks down the alcohol quickly and “efficiently” – and the person unconsciously learns to make good for the deficits caused by alcohol. However, the harmful drinking will be obvious in the long term. Habituation generally means that drinking has long been established, and that you have started behaving as if you are not under the influence.

Just a little amount of alcohol can affect the heart rate, blood pressure and the heart’s ability to pump to maintain blood circulation. These reactions can be serious if there is an existing heart disease. However, as of a certain age, regular and moderate drinking in a perfectly healthy person can provide some protection against cardiovascular disease. But these benefits can be achieved with simple efforts and you don’t need to kill the mosquito with a gun. There are much easier and safer alternatives.


Alcohol causes the small blood vessels under the skin to dilate, among other things. This explains the pink complexion in heavy drinkers and as a result this dilation also causes heat loss. Contrary to the popular belief, it is dangerous to drink to ‘warm up’ when exposed to cold, just because you feel energized after drinking. Fact remains that you are losing heat, continuously.  The intestines begin to secrete acid after drinking. As the BAL rises, a digestive enzyme pepsin is reduced which leads to irritation of the intestinal walls. Drinking causes a sudden increase in blood sugar and the pancreases reacts by a rapid drop in blood sugar. This in turn causes symptoms of low blood sugar levels like dizziness, headaches, difficulty concentrating, anxiety, trembling and cold sweats begin to appear.

More information means better decisions. Understanding the effects of alcohol can help you estimate you BAL, considering the various factors that affect the rate of alcohol absorption into the blood circulation. This information is vital for those who have a demanding job like a pilot or a surgeon. Of course, it is certainly good to know how much alcohol you have absorbed before you drive, but there are better reasons for understanding how alcohol affects the various organs and systems in your body. More information helps you make better choices and when you have more knowledge, you tend to make more enlightened decision. Ultimately, we hope that people who know more about the subject will understand the very real impact alcohol has on the human body. Well-informed people will be more conscious of the unpleasant and dangerous side-effects of abusive drinking. We hope, you will be more aware than ever that irresponsible and mindless drinking is always in bad taste.
