The human brain is a complex mechanism and a very sensitive organ. If it functions properly, a person enjoys mental and physical balance. When the “command center” begins to fail, problems arise, including lack of concentration and memory lapses. What habits negatively affect brain function? Which daily activities are better to give up?
- If a person is awake several nights in a row, his brain begins to falsify reality and create unlikely visions
- The brain needs approx. 300 kcal for passive functioning – during increased activity the demand increases, therefore a balanced diet is necessary
- In 1995, scientists discovered the link between the way people think and how the brain works
- Smokers have a thinner cerebral cortex, it is necessary to part with cigarettes in order to rebuild the brain structure

Too short sleep – how does it affect the work of the brain?
Sleepless nights or too little sleep are becoming the “norm” for busy people, diligent students, young mothers and party lovers. However, chronic sleep deprivation has a very negative effect on brain function. All thanks to the glial cells present in our most important organ. Under normal conditions, they help to get rid of the faulty components, which improves the functioning of the nervous system. In a situation where a person does not sleep regularly, the glial cells increase their activity, destroying healthy neurons.
Scientific experiments confirm the link between abnormal brain function and poor sleeping habits. Prof. Michele Bellesi from Universita Politecnica delle Marche in Italy observed changes in the brains of mice forced to sleep too short. In this case, microglial cells were activated, which occurs in the human organ, among others, in Alzheimer’s disease. In turn, scientists from Michigan State University prove that just one sleepless night disturbs the processes of remembering and may falsify memories.

No breakfast – how does the brain react?
Living in high gear and the constant rush that accompanies it, many people miss the most important meal. A healthy breakfast – because we are talking about it – not only has a positive effect on metabolism, but also ensures smooth functioning of the brain throughout the day. A wholesome meal rich in complex carbohydrates (e.g. whole grain bread, oatmeal), proteins and fats should be eaten within an hour or two after waking up. Thanks to nutrients, the body produces, among others neurotransmitters that are responsible for the proper functioning of the nervous system.
- What is best to eat for breakfast? Five suggestions
A person who skips breakfast usually experiences symptoms such as lack of concentration, depressed mood, and embarrassing memory lapses. These symptoms can be explained very simply. It is enough to imagine that the brain – the organ responsible for the work of the whole body and sending millions of impulses throughout the day – is cut off from the primary source of energy. This unhealthy practice leads to a situation in which a person more than compensates for the lack of calories at the beginning of the day and more willingly reaches for high-calorie foods.

Smoking cigarettes and brain function
Smoking not only causes lung cancer, it also causes negative changes in the brain. In addition to hypoxia, the relationship of this addiction with the thickness of the cerebral cortex was indicated. It is thinner in smokers than in people who do not smoke. In practice, this means impairment of functions such as:
- proper use of the language
- correct perception
- ability to concentrate
- memorizing.
Researchers from the Montreal Neurological Institute in Canada and the Scottish University of Edinburgh studied a group of 500 smokers of various ages. There were more areas in their cortex where it was much thinner. Fortunately, it has also been proven that harmful processes can be reversed. Quitting smoking will help. People who give up the addiction have a chance to re-grow the outer layer of the cerebral hemispheres, but its full regeneration is not possible.
Unhealthy Diet – The Effects of Sugar and Fat on the Brain
Simple sugars, including in sweets and carbonated drinks, they promote weight gain, and also adversely affect the brain. Research confirms that an excessive amount of simple carbohydrates in the diet worsens memory, lowers concentration and increases the risk of depression. Saturated fats, which can be found, for example, in sweet snacks, fatty sauces or processed cheese, have a similar effect.

The human brain is an extremely demanding organ. With minimal activity, it uses about 240 kcal per kilogram of its mass. In practice, this means that the organ uses about 300 kcal per day. To ensure its proper functioning, it is worth verifying your eating habits. It should be rich in nutrients (carbohydrates, proteins, healthy fats from vegetables, seeds and fish) in the right proportions, vitamins and minerals. In addition, you can add 10 – 12 tablespoons of white sugar a day without remorse – according to the opinion of the WHO (World Health Organization), this amount should not harm your health.
To support the proper functioning of the brain, supplementation with appropriate preparations can be started. We recommend, for example, Enteril energy and vitality Pharmovit available at an attractive price on Medonet Market.
Everyday stress and its harmfulness to the brain
Short-term stress can mobilize the body to act, but in its chronic form it has serious consequences for human health. Being under pressure for a long time has an impact on the work of the brain. Scientists from the Institute of Experimental Biology of the Polish Academy of Sciences M. Nencki in Warsaw proved that connections between nerve cells are destroyed under the influence of strong stressful stimuli. This can lead to changes in the brain, which is one of the causes of depression.

Research conducted by the Stockholm Brain Institute has also shown that the nervous system of people experiencing chronic stress functions as if they were suffering from PTSD (Post-Traumatic Stress Disorder). To this must be added problems with memory and concentration disorders.
For memory and concentration, you can use Memory and concentration – Pharmovit drop extract consisting of Siberian ginseng root extract, gotu kola herb extract, Rhodiola rosea root extract, Ginkgo biloba leaf extract.
Modern technologies – how do smartphones affect the human brain?
It is difficult to imagine everyday life without a smartphone. As it turns out, this practical device can have a negative effect on the work of the mind. Scientists suggest that too frequent use of modern technology disturbs the chemical balance of the brain. While looking at the screen for many hours, a person experiences intense stimuli, the excess of which leads to:
- stanow lękowych
- insomnia
- exhaustion
- irritability.
Modern technologies – despite their obvious advantages – often lead to addiction.
Excessive consumption of alcohol and its harmful effects on the brain
Consuming alcohol in moderation does not harm your health, but overusing it can lead to irreversible changes in the brain (and more). Drinking too much alcoholic beverages threatens, among others, by temporary loss of consciousness, but also permanent damage to nerve cells. It is for this reason that alcoholics suffer from impaired speech, memory and delirium tremens. The latter defines a serious disturbed state of consciousness which includes delirium, hallucinations and delusions.

Avoiding Physical Activity – Why Is It Bad For Your Brain?
A sedentary lifestyle has a negative impact on weight and overall physical condition. Habitual sitting on the couch after work has other disadvantages. Lack of physical activity reduces the supply of oxygen to the brain. Insufficient air can cause:
- chronic fatigue
- lack of energy and motivation to act
- depressed mood
- headaches
- anxiety
- disturbance of concentration and memory.
Regular exercise can reverse this process, resulting in good physical and mental form. Importantly, practicing sports is a stimulus that causes the body to release serotonin, commonly known as the “happiness hormone”. It is responsible for pleasant sensations as a compensation for your effort.
Lack of mental training – why is it bad for the brain?
The brain – like the body – needs properly adjusted exercises to develop. If this element is neglected, the mind gradually loses its ability to remember and associates facts with much less brilliance. In addition, the risk of developing dementia or Alzheimer’s disease in old age increases. Mental training that combines business with pleasure comes to the rescue. The most common practices are:
- social conversations on engaging topics
- crosswords
- logic games
- puzzles
- learning foreign languages
- reading books
- writing.

Negative thinking is bad for your brain
Seeing the world in black is the domain of pessimists, which can become a habit that is dangerous to your health. Thousands of thoughts flow through the human mind every day, and each of them triggers specific reactions in the brain. In 1995, scientists from the National Institute of Mental Health proved that there is a connection between a particular way of thinking and the activity of this organ. Negative thoughts – fears, worries, bad memories – cause the central organ to produce the chemical responsible for deteriorating mood.
Persistent pessimistic thinking leads to long-term changes in the mind. It often becomes the cause of anxiety disorders or other psychological ailments. By itself, a negative attitude can effectively make everyday life difficult. Fortunately, you can eliminate this habit by cultivating positive visions.
