Your brain is one of the most important organs in your body. As we all know, our lifestyle habits affect our general health.

Its delicate structure can be easily damaged and thus cause various serious health issues and complications. According to the World Health Organization, these are the top 10 brain-damaging habits nowadays.

No Breakfast

We constantly hear that the breakfast is the most important meal of the day, but you surely know a lot of people who avoid it on a daily basis, including the ones who tend to reduce blood sugar levels.

However, after the night of no food, the avoidance of the breakfast will provide insufficient amounts of nutrients to the brain, and if repeated, it can lead to brain degeneration.

Overeating of Fat Damages the Brain

We all know about the dangers of having too much fat in our diets, however, eating too much fat can also damage your brain. Scientists have discovered that fatty foods can rewire the brain to start craving foods that are high in fat.

A study carried out by the Neuroscience Program in Substance Abuse at Vanderbilt University found that people who regularly overeat fatty foods develop a defect in the brain. This defect causes the brain to send signals to continue eating, even though the person is technically feeling full.5 So, the brain’s system that is used to curb appetite starts to make a person crave fatty foods and this results in obesity and other health problems.

Excessive Sugar Intake

Sugar intake has long been associated with several health complications, from obesity all the way to cancer and other life-threatening conditions. For some reason, we still end up taking excess sugar either knowingly or unknowingly. The effects are heartbreaking.

Apart from the many conditions it keeps you at risk of contracting, you may be surprised to know that it also causes damage to your brain over time. This is because loads of sugar in your bloodstream prevents proteins and nutrients from being absorbed.

Head Covered While Sleeping

It may sound strange, but this habit reduces the intake of oxygen during the night, and while sleeping, one cannot feel the light-headedness or air deprivation. Additionally, there is an increased risk of inhaling excess carbon dioxide.

Excessive Alcohol Consumption

Alcohol consumption affects your body in many ways and it has long-lasting damaging effects on your brain even after it left your body.

According to the U.S. Department of Health & Human Services, alcohol affects the brain in many ways, such as impaired memory and slowing in reaction times. People who have been consuming large amounts of alcohol for extended periods of time run the risk of developing serious and persistent changes in the brain that persist well after the person achieves sobriety. The damage can be a result of the direct effects of alcohol on the brain or may result indirectly, from a poor general health status or from severe liver disease.


Just when you had thought that overeating was already causing a lot of negative health effects to your body, then this?

Yeah, get used to it already. Apparently, when you overeat the brain arteries harden, decreasing our mental power.  Do I need to add that overeating also causes low self-esteem, weight gain and bloating? I don’t think so. I guess there is no stopping when it comes to overeating as far as threatening our lives is concerned. Avoid this habit as much as you can. Eating a heavy healthy breakfast is a nice way to start.

Lack of Stimulating Thoughts

Thinking expands the brain and supports its function, so this potent tool significantly improves the brain and opens new pathways in the mind.

The neuroplasticity of the brain ensures that you will either enhance the mind, or the brain will shrink and your lack of interest and reduced efforts will decrease your skills and abilities.

Lack of Social Integration

Psychologists generally agree that our brains function best when we have opportunities to socialize with others. The website Psychology Today says that lack of social contact can lead to depression, feelings of loneliness, and even affect our ability to remember things. Children who don’t get enough social contact with their parents and peers are more likely to develop psycho-social problems. In adults, a lack of social integration can also lead to forming bad habits like over drinking and drug abuse.

To avoid a lack of social integration, it is important to look for ways to socialize with others. For example, the University of Michigan studied how social integration can help boost mental abilities. The researchers reported that even just regularly talking for 10 minutes a day can boost memory and mental performance.


Smoking is a damaging habit for your brain and other organs in your body. A team of researchers found that chronic smokers experience a drop in dopamine function in the brain. This drop in dopamine is a factor that leads to addiction and also increases the chance of relapse when trying to quit. The researchers found that when a person quits smoking, dopamine levels normalized, thus showing that low dopamine function isn’t a precursor to smoking.
