Human nature is designed in such a way that a person grows old and dies. Aging of the body is not as bad as aging of the brain. Our brain begins to age first and begins to age after 25 years. By the age of 70, a person’s cognitive functions - memory, thinking, reaction speed - decrease by about 50%. Brain aging occurs in every person. But it’s difficult to say when it will come. Everything happens individually for each person. One of the main reasons for brain aging is slower reaction speed. How do you know if your brain is starting to age? Scientists have proven that the first sign of brain aging is a change in posture. Correct posture - relaxed vertical position of the body, horizontal level of the shoulder girdle, symmetrical arrangement of paired organs, flat stomach. With correct posture when moving, all internal organs are protected. Correct posture is a person’s calling card. When your posture is poor, discomfort appears, pain in the spine, difficulty breathing, you want to sit, headache, dizziness, rapid heartbeat, tightness, bad mood. Poor posture occurs slowly, the person does not notice it. When posture deteriorates, a “silhouette of old age” appears. Therefore, it is necessary to delay old age as long as possible. We need to consider in time when our posture worsens. After all, there are certain moments that show that your posture is changing. Your teeth begin to hurt and fall out. A person chews only soft foods; he does not eat hard foods. Chewing functions are impaired. Chronic diseases of the nasopharynx. When a person is healthy. He breathes through his nose, all airways are open. If he breathes through his mouth, then the airways are shortened. A person has a reduced number of nerve impulses that go to the brain. Some impulses do not reach the brain, its tone decreases, and it affects muscle tone. The second sign of brain aging is decreased concentration. This is the difficulty of learning something new. Attention is interest in something. Concentration is the collection of energy. Our intellect attracts attention and interest. The joint work of our intellect and emotions achieves concentration. When we don’t want to do anything, there is no interest in anything, then our intelligence works at 2%. It disrupts concentration. The reduction of our attention depends on intelligence. Therefore, it is necessary to develop your intelligence at any age. With a decrease in concentration of attention: It is more difficult to learn something new, Memory impairment appears and the cognitive methods of the brain are disrupted. Loss of mental, then physical endurance. Problems appear in communication, lethargy appears. They try to avoid communicating with people who influence negatively, who have a different opinion , another look. Each person has his own views, his own thinking. If views do not coincide, this does not mean that you cannot communicate with a person. Compare different opinions - this is the environment when new cognitive abilities appear. Slowness in movement, orientation, space. When the intellect does not work fully, then freedom appears in emotions. Moods and emotions often change. People become more careful and thoughtful. We can't stop the aging process, but we can slow down the rate at which the brain ages. This is an active lifestyle, physical exercise, proper nutrition. Walk more in the fresh air, enjoy nature. You can play a musical instrument, this will help avoid cognitive changes and preserve your hearing. Read, learn foreign languages, train your memory, feed your brain with new knowledge, communicate more. Maintain a stable psychological state. Focus on positive information and maintain a positive mood. After all, aging is not a disease, but a new stage in human development, a new stage in his life. It is important to discard all negative preconceptions about brain aging and constantly.
