What is harmful to our brain?

admin Health 134

Who among us does not want to keep youth and clarity of mind for many years? The health of the whole organism depends on the health of the brain. It is this organ that allows us to live, think, plan , experience emotions and devote time to our favorite activities.

Agree, it would be great if scientists invented a drug that can prolong life and save us from diseases forever. But, unfortunately, this still remains an impossible task.

However, this does not mean at all that it is now possible to put an end to attempts to prolong the youth of the brain. Everyone’s health is in his hands, and something supernatural is not required to preserve it.

What can happen to the brain?

The brain is the most important, most complex and at the same time the least studied organ in the human body. Its possibilities are great, but at the same time they are far from being fully utilized .

Scientists around the world conduct hundreds of studies every day to find out exactly how the brain works. Thanks to their work, we already know how it functions, what capabilities it has and what failures in its work are possible.

Even the most well-oiled mechanisms fail sooner or later. The human brain is no exception. Over time, age-related changes begin to occur in it , affecting the entire body as a whole. This is a natural process that cannot be stopped, but it is possible to slow it down.

These changes include:

  • decrease in intellectual abilities;
  • memory impairment;
  • apathy;
  • irritability;
  • insomnia
  • deterioration of the general condition of the body;
  • senile dementia;
  • decreased body reactions;
  • Alzheimer’s disease.

This is not a complete list of negative consequences that can arise from neglect of the most important organ in the human body – the brain.

But sometimes this kind of change begins to occur in fairly young people. This is due to the wrong way of life and the abuse of things that cause irreparable harm.

Before figuring out what needs to be done to maintain brain health at the proper level, it is important to understand what exactly can harm it.

Let’s talk about mistakes that can be too expensive.

Lack of communication

People who avoid communication are much more susceptible to age-related changes in the brain than those who like to once again exchange a few phrases with a colleague or neighbor.

Numerous studies show that even 10 minutes allocated for communication daily can activate neural responses . The more a person spends time alone, the slower the connections between neurons begin to work, which, in turn, leads to a slowdown in many thought processes.

The good news for introverts is that face-to-face communication is not required to keep the brain healthy. Talking on the phone or making an online call can also activate neural connections.

Lack of complex tasks

Many people figuratively call the brain a muscle that needs regular exercise. Just as an athlete who quits classes begins to lose strength, endurance, and muscle mass, our brain loses its basic indicators without constant stress.

Scientists believe that the peak of maximum brain activity falls between 16 and 25 years. It was during this period that its effectiveness reaches large limits. Later, in the absence of new unusual tasks, the performance of the brain declines.

Our brain is designed in such a way that when we master an unusual type of activity or immerse ourselves in an unfamiliar area, be it a foreign language or a hobby, new neural connections are formed in its cortex.

The more such neural connections arise, the more flexible the human brain becomes and the longer its health remains. Regular smart exercise is vital to prevent Alzheimer’s and senile dementia.

Frequent use of a mobile phone

Horror stories that the abuse of smartphones leads to the onset of cancer have become part of our lives. Research that would certainly confirm this theory does not exist at the moment, and therefore at the moment it remains just a guess of scientists.

However, this does not mean that the radio waves emitted by telephones do not affect the brain in any way. For example, Swiss and Belgian scientists have conducted a study on the effect of smartphones on memory. After analyzing the telephone habits of 700 teenagers aged 12 to 17, they came to the conclusion that electromagnetic radiation from mobile phones negatively affected the ability of children to remember information , especially abstract images.

It was also interesting that a stronger effect on memory occurs when the phone is at the right ear during a call.

This is why scientists recommend cutting back on phone calls or using a headset when making calls.

Lack of oxygen

Spending the whole day in a stuffy office, and then the rest of the evening at home in front of the TV or buried in a smartphone screen, a person deprives his body of precious oxygen. An insufficient amount of it contributes to a decrease in the performance of the brain. This translates into fatigue, poor concentration and decreased reaction rates.

People who have a habit of covering themselves with a blanket while sleeping tend to feel more overwhelmed and tired in the morning than those who sleep with open windows and in well-ventilated areas. This is due to the fact that, under the blanket, a person begins to breathe already “processed” air, saturated with carbon dioxide, thereby forcing the brain to experience oxygen starvation.

Insufficient amount of consumed clean water

Our brains need water as much as all living things. The human brain is 80% composed of this valuable fluid. It is with its help that the delivery of nutrients occurs, due to which it begins to function more efficiently.

When the body becomes dehydrated, the brain is one of the first to suffer. A person begins to experience weakness and fatigue, he has headaches and changes in blood pressure.

Doctors recommend in such cases instead of a pill, first drink a couple of glasses of clean water. As a rule, relief comes almost immediately.

Bad habits

There are many studies on the harmful effects of cigarettes and alcohol on the human body.

The brain of a smoker or a person who regularly drinks alcohol (regardless of their strength) undergoes serious neurobiological changes.

Thus, smoking contributes to a decrease in the thickness of its bark, as a result of which mental abilities and level of thinking decrease. And the ethyl alcohol contained in alcohol destroys the connections between neurons, which also does not lead to anything good.

People suffering from bad habits accelerate the aging process of their brain several times compared to those who lead a healthy lifestyle.

Lack of physical activity

Sports and a healthy lifestyle are needed by the body to maintain muscle tone, increase endurance and improve overall health. Through physical work, blood begins to actively circulate throughout the body, saturating the brain cells with nutrients and oxygen. This has the best effect on long-term memory.

In addition, people who do not engage in any physical activity are often overweight. Obesity results in an increase in free radicals and inflammation, which leads to a decrease in the number of brain cells. This, in turn, contributes to memory problems and premature aging of the organ itself.

Improper nutrition

The brain, like the body, needs nutrients that enter the body with food. Accordingly, if a person eats foods that are not fortified with vitamins, minerals and other useful nutrients, the brain begins to experience a deficiency of them, which leads to a deterioration in its work.

Here’s a list of things to avoid:

  • fast food;
  • fried and fatty foods;
  • smoked meats;
  • foods containing trans fats;
  • ice cream;
  • too spicy or salty food;
  • foods containing sugar and sweeteners.

Ideally, these products should be abandoned forever, since they do not carry any nutritional value for the body. But if you don’t think it is real to forget about your favorite hamburgers or sweets, reduce their consumption to 1 time per month.

In addition to junk food, strict diets that exclude essential micronutrients from the diet also negatively affect the work of the brain.

Skipping breakfast also causes great harm to the main organ. Scientists studying the effect of food intake on the brain have concluded that children who eat breakfast regularly perform better than those who skip the most important meal of the day.

Bad dream

Poor sleep negatively affects the human body and especially the brain. After a bad night, concentration, productivity and energy decrease. Instead, a bad mood, apathy and irritability appear.

On the quality of sleep is affected by many factors, among which are:

  • too many or too few hours of sleep;
  • insufficient darkening in the room;
  • uncomfortable bed and pillow;
  • uncomfortable room temperature;
  • lack of oxygen;
  • lack of silence during sleep.

During sleep, the important hormone melatonin is produced in the human body. Thanks to him, the aging process slows down, the general well-being and condition improves. Melatonin has anti-stress and anti-tumor properties.

That is why people who competently approach the issue of sleep keep the brain healthy and youthful for a long time.

We have not considered the entire list of habits and things that negatively affect the brain, but even this is quite enough to be critical of your lifestyle. And now, understanding what exactly is harmful to brain health, we can introduce new, useful habits into our lives.

How to keep your brain healthy?

To maintain the productivity of the brain, you do not need to spend money on expensive medications or gather a consultation of doctors. Keeping a clear mind is within the power of each of us, just a little change in our lifestyle.

We have prepared several recommendations for you:

  1. Eliminate bad habits. Smoking and drinking alcohol have not yet benefited anyone. Your body will thank you, and the efficiency of the brain will increase significantly.
  2. Go in for sports . Take at least 30 minutes a day to exercise or take long walks in the fresh air. Soon you will notice how your sleep will improve, your mood will improve, your energy will increase, and your body will tighten and your muscles will tone.
  3. Improve your sleep quality . Darken the room and remove all sources of noise. Remember that melatonin is produced in complete darkness. Establish a mode of activity and rest, allocating 6-8 hours of sleep every day.
  4. Chat and have fun. Having fun and relaxing in the company of others is good for the brain because it can help reduce stress in the body and trigger rejuvenation.
  5. Minimize your time on the Internet . Instead, hang out with friends, go for a walk, or read a book. The latter, by the way, is useful not only because it will make you more erudite, but also because it activates those areas of the brain that may not be included in everyday life.
  6. Increase the complexity of the tasks. By regularly training your brain with the help of solving complex issues and mastering new skills, you start the process of forming new neural connections, thereby preserving the youthfulness of the brain for many years. You can train your brain anytime, anywhere. And our online program “Cognitive Science  will help you with this , in which you will not only study in detail many techniques of thinking, but you will also be able to immediately apply them in practice.
  7. Eat right . Eat foods rich in vitamins, minerals, and other nutrients. Avoid skipping breakfast, as lack of it leads to a decrease in blood glucose levels, which in turn negatively affects the functioning of the brain. Eliminate food junk from your diet and add vegetables, berries and fruits to it on a regular basis. Don’t forget about your drinking regime. Drink 2 liters of clean water a day (black tea, coffee, and sugary drinks are not included).

Introduce healthy habits such as healthy eating, physical activity, regular brain training and adherence to sleep into your life, and you will forget about problems with memory, concentration and preserve brain health for many years.


Despite the fact that thousands of studies have been devoted to the brain, it still remains the most mysterious organ in the human body.

Understanding which habits and actions negatively affect the brain allows us to correct the situation in time. With a correct and careful attitude to such an important organ, he will reciprocate and preserve not only his health, but also the health of the whole organism as a whole.

Take care of yourself!
