how much alcohol is safe

There is a relationship between alcohol and heart attack. Alcohol causes extensive damages to the cardiovascular system.  Alcohol of any form like binge drinking, heavy drinking, or alcohol use disorder, that is AUD leads to heart diseases.

Several studies conducted to find out the relationship between alcohol and heart attack found that any kind of alcohol intake along with being obese or overweight increases the risk of heart attack by 40%.

Another study conducted by the Centers for Disease Control and Prevention or CDC revealed because of alcohol abuse, 88000 Americans on average die every year.

According to the CDC alcohol abuse of any kind causes clots and hardened arteries that lead to a heart attack. Drinking too much alcohol blocks the arteries of the heart so blood flow to the heart becomes less hence the heart does not get the proper amount of oxygen that it requires. It furthermore causes weakening of the heart muscle, which causes the death of the heart muscle, and finally, the heart stops breathing.

Let me give you a chart of SEVEN bad effects on alcohol your heart and overall health –

  1. Alcohol directly suppresses your immune system and increase your chances of having infections,
  2. Alcohol can directly inhibit your heart muscles and leads to alcoholic cardiomyopathy,
  3. Alcohol increase body weight,
  4. Alcohol has very high dependency and certainly can lead to addiction,
  5. Alcohol increases cognitive difficulty and makes you more reactive and less creative,
  6. One study showed alcohol increases up to 50% in increase in sudden death due to heat electrical issue known as ventricular arrhythmia
  7. Increases risk of stroke.

Now having said that – the scientific community will argue that this is how alcohol is safe –

Up to 20 to 40 gm per day for 3 to 5 days a week


2 to 3 drinks per day for 3 to 5 days a week.

Any poison is safe at lower dose and even may provide some medicinal benefits. But here the catch who leaves the dose of that medicines in the hands of patients. Especially when we all know that alcohol is addictive and it has significant chances of addiction.

Once you are in that “NEED” zone – it will destroy you from your heart, brain, physical and mental health.

Alcohol is kept in the bars, hotels, restaurants, local shops and places of celebration. And alcohol by any definition is a drug. The placement of alcohol with such easy reach promotes addiction and dependencies. Especially when the person who will earn money selling it more.

If a safe drinking is advocated – the alcohol should be made a prescription medicine and a pharmacist should dispense it.

Remember “prevention is always better than cure”.

How alcohol causes a heart attack?

Alcohol drinking can be kept in three different categories as moderate drinking, binge drinking, and heavy drinking. So, let’s check out the relationship between the amount of alcohol intake and heart attack:

  1. Moderate drinking

For some people drinking a moderate amount of alcohol lowers the risk of heart attack as it has some relaxing effects on the mind. But drinking more than three servings of alcohol increases the risk of heart attack as it boosts the level of toxic substances in the blood. Moreover, drinking too much too often leads to an increase in the lipids of the blood that is a type of fat. Furthermore, it leads to hardening of the arteries and increasing arterial plaque and cholesterol. Thus, it can cause a heart attack at any time.

  • Binge drinking

Binge drinking is more harmful to the body than moderate drinking. A quick and high level of alcohol consumption that can cause intoxication in a person is called binge drinking. A person with an underlying heart problem is more at risk of heart attack if he consumes large amounts of alcohol at a time. As it results in blood pressure to quickly rise and make way for a heart attack. The research found that drinking six or more servings of hard liquor at a particular time boosts the risk of stroke or heart attack for seven days after it.

  • Heavy drinking

Heavy drinking doubles the risk of a heart attack in a person. According to research, the risks of heavy alcohol drinking are high blood pressure, irregular and rapid heartbeat which leads to the 2.3-fold risk of congestive heart disease and failure. This contributes to an increased risk of a heart attack later in life. Therefore, alcohol is directly proportional to the heart attack as it increases the risk of heart attack by 1.4 times.

Let’s discuss few commonly asked questions on ALCOHOL– FAQs
