Sometimes, as a human being, you may do some things that endanger your body. The action which may destroy your brain sometimes has nothing to do with yourself. For example, brain diseases and ailments.

When I started looking at this article and the question about the action that may destroy your brain,  I sometimes lean towards the activities that one takes to intentionally hurt their brain. Think of it more like taking unnecessary risks that could cause injury to your brain.

The brain is affected by factors that we do not always pay attention to in our daily lives: the main factors that destroy the brain.

From the food we eat, the bad habits we have developed over the years, and the extent to which we use the brain, all of these factors play a role in our intellectual development, sometimes increasing it and reducing it.

Some habits are known to reduce intelligence by killing brain cells and promoting mental retardation, but fortunately, the key is to avoid these bad habits. You can learn not to destroy organs.

Below is the action which may destroy your brain

  • Smoking
  • Increased sugar consumption
  • Continuous exposure to pollutants
  • Lack of enough sleep
  • Overeating or undereating
  • Wine
  • Violent reaction or premature stressors
  • Covering your head while sleeping
  • Stressing the brain when sick
  • Mental stimulation and lack of exercise
  • Skipping breakfast
  • High Temperature.

Just to be clear, these self-harming actions can be changed as a part of a healthier movement.


Bad smoking habits can significantly reduce the quality of your brain. It also limits the supply of oxygen to the brain. It is associated with the development of neurodegenerative diseases such as Alzheimer’s disease.

Heterocyclic amines released during the burning of cigarettes can also prevent the proper replication of DNA. In short, it causes mutations that can cause mutations in cancer cells.

Increased sugar consumption

Sugar dependence is one of the habits of damaging the brain. If your diet usually contains refined sugar, white flour, fried foods, and packaged foods, you may hurt yourself. This is especially true for diets that lack enough vegetables, fruits, and fiber. This diet promotes the accumulation of harmful substances in the body.

This increases cancer risk, distorts the immune system, causes malnutrition, and can disrupt neurodevelopment. The food you eat maybe a brain-damaging habit.

Continuous exposure to pollutants

The brain needs to supply oxygen frequently. Various toxic substances can interfere with the exchange of gas and oxygen and their transport to cells. This can reduce the efficiency of the brain.

Lack of enough sleep

You need 8 hours of sleep each night to rest. Sleep also contributes to the normal development of energy-producing metabolic processes. When you are dreaming, cell remodeling also happens. Lack of sleep accelerates the short-term death of brain cells. Also, I get tired all day long.

Overeating or undereating

If you eat more food than your body needs, residues can build up in the form of fat. It also strengthens the cerebral arteries, thereby affecting their normal functioning.

The facts prove that, under the strict control of the diet, the human body is not the only one that loses weight. Studies have shown that, due to severe nutritional restrictions, the brain is eating. This is another reason why it is more reasonable to stick to your eating habits. Don’t get tired of eating the “hungry” diet properly.


Drinking is one of the habits that hurt your brain. Alcohol hurts any organ. Moreover, the nervous system, heart, and liver are the most vulnerable parts of the body. It also affects the chemical reactions that occur in the brain.

Alcoholism also kills neurons and reduces the transmission rate of nerve impulses. Not only can it damage parts of the brain, but it can also damage the rest of the body.

Violent reaction or premature stressors

Stress can cause a variety of reactions in the nervous system. Some reduce intelligence and increase the risk of stroke and heart attack.

Covering your head while sleeping

Get enough sleep, and don’t forget the habit of destroying your brain. Sleeping in the headrest increases the concentration of carbon dioxide in the brain. Similarly, it reduces the amount of oxygen that may have a detrimental effect on your brain.

Stressing the brain when sick

Doing a lot of work and study when you are sick is harmful because you cannot transfer your body’s energy from treatment. Forcing the brain to overwork during this period can reduce the efficiency of the body. Besides, it can further weaken the immune system. This makes it easier to tolerate more types of illness.

Mental stimulation and lack of exercise

Nothing is more important than thinking, talking wisely, reading a book, or finding words that stimulate your brain. Such activities can improve learning ability and memory. Not only that, but it also helps reduce response time to stimuli.

Skipping breakfast

Skipping breakfast is one of the habits that hurt your brain. Breakfast is the most important meal of the day as it can significantly impact performance, endurance, and emotional status. Early in the morning of the day, the brain distributes nutrients. This task helps it to continue to “control” physiological processes after a long fast.

Skipping breakfast can lead to a lack of energy, lack of concentration, and amnesia. Not only that, but other methods can also affect it. Experts have discovered that it can lead to depression and poor physical and mental performance. Eat a basic healthy breakfast

High Temperatures

Staying in high temperatures for a long time usually makes you feel bad. It is difficult for us to think and work, let alone sleep.

As mentioned earlier, our brains need adequate ventilation and adequate oxygen. During high temperatures, the arteries that carry oxygen to the brain harden, and blood flow decreases. Therefore, our brain will also slow down its function, at least until the temperature is correct.


To experience better brain function, avoid habits that destroy mental health, and learn new ways to support brain function.

Solitude is not only bad for your overall mood but also dangerous for your brain. Moreover, it is highly recommended that you meet in a social group to discuss different topics.

Engaging in intellectual dialogue challenges the brain to produce very healthy thoughts, opinions, and solutions.

No matter what bad habits you have, positive changes will always be reflected in you. Therefore, first, learn what will kill your brain.
