With the increase of age, various physiological functions decline, and some aging phenomena appear, such as the gradual atrophy of nerve tissue, especially brain cells, which leads to the weakening of mental activity, slow response and memory loss, especially in near memory. Vision and hearing are also gradually declining. Age spots appear on the skin, and the hair turns white and decreases. With the decline of the function of bone and muscle system, the exercise ability also decreases.
2. It is the change of social status.
Due to the change of social status, some elderly people will have various psychological changes, such as loneliness, inferiority, depression, irritability and negativity. These psychological factors will promote physical aging.
3. It's family relationships.
After retirement, the main activity place of the elderly will change from work to family. The relationship between family members has a great influence on the elderly, such as children's attitude towards the elderly and the contradiction caused by the generation gap, which will also have an impact on the psychology of the elderly.
4, it is nutritional status.
In order to maintain the normal physiological activities of human tissues and cells, we need adequate nutrition, such as protein, sugar, fat, water, salt, trace elements and vitamins. In particular, nerve tissues and cells need nutrition more. When the nutrition is insufficient, people often have mental and neurological symptoms such as listlessness, fatigue, memory loss, lack of interest in external things, and even depression.
5, aging and disease
Aging is not a disease, but it is closely related to it. This is because the aging process is inevitably accompanied by the decline of various functions, the adaptability to external environmental changes is weakened, the compensation function is low, and it is difficult to maintain the internal stability of the body, so the aging body is prone to diseases.
The aging body has its unique disease spectrum: coronary heart disease, malignant tumor, degenerative diseases of brain and organs, cerebrovascular accident, infection, diabetes and so on. With the increase of age 10 years old, the mortality caused by cardiovascular diseases will increase by 2-3 times, as will infectious diseases and malignant tumors.
