In daily life, you can often hear a sentence on the lips of the elderly: "It's not okay to be old if you don't accept old age." When you reach age, the body first begins to react, and all aspects are not as good as before, and all kinds of diseases also follow, so that the elderly friends can experience the ruthlessness of the "years".
1. At the age of 70, people will begin to age "off a cliff".
At this stage, everyone's living conditions are relatively good, many people can't see their actual age, and people in their forties and fifties still look very young and energetic. But I don't know if you feel it, once you are over 70 years old, your body will have obvious aging, and you obviously feel that it is not as good as before in all aspects, this is not a personal illusion!
In June 22, researchers from the University of Cambridge published a study in Nature that pointed out that after the age of 70, the structure and differentiation pattern of human hematopoietic stem cells have changed dramatically.
Specifically, there are different types of stem cells in hematopoietic stem cells of people under the age of 65, which can differentiate red blood cells and white blood cells, with high clonal diversity and stability, and little impact; After the age of 70, 10~20 stem cells will differentiate half of the blood cells, and the clonal diversity will be significantly reduced, which is easy to have a negative impact on health.
Researchers say that as we age, stem cells in the body will accumulate mutations, and by the time we are in our 70s, these abnormal stem cells will become mainstream, dominating blood cell production and dominating the bone marrow.
This can lead to a decrease in blood cell diversity in the elderly, disrupt the production of normally functioning blood cells, and induce a variety of aging-related diseases. This "catastrophic" change in aging also explains why people feel visibly fragile and aging after the age of 70.
Second, these 5 diseases are old people, and overtreatment will hurt the body
In life, many elderly people feel that they are useless when they are old, and they are worried all day long for fear that they will get sick. But many "diseases" are not sick in the eyes of doctors, but just old. Even many "diseases" do not need to be treated, and blind treatment will increase the burden on the body.
Professor Yu Guolong, from the Department of Cardiovascular Medicine, Xiangya Hospital, Central South University, said that these five diseases are normal aging and do not require medical intervention.
1. Insomnia
With the increase of age, the pineal gland in the brain will gradually shrink and even calcify, resulting in the weakening and disappearance of the biological clock, and the secretion of melatonin will also decline significantly.
After the age of 35, it will decline at a rate of 10~15% every 10 years, which is also the main reason for the occurrence of sleep disorders and insomnia in the elderly.
2. Osteoplasty and porosity
Both diseases can cause bone and muscle pain in the elderly, the occurrence of osteoporosis is associated with the loss of bone and bone density due to age, and the occurrence of hyperostosis is associated with the asymptotic degeneration of the osteoiliac muscle, resulting in ligament atrophy, decreased joint support/protection, and increased articular surface irritation.
3. Presbyopia
It is manifested as the inability to see near objects, and the symptoms become more and more severe with age, which is a normal physiological phenomenon after the increase of age. Associated with lens hardening and decreased elasticity.
4. Premature cardiac beats
This is the most common arrhythmia symptom, most patients have no other discomfort, only a small number will have palpitations, discomfort and other symptoms.
It can occur after excessive stress, smoking, drinking, or drinking strong tea, and most are not related to organic disease and do not require deliberate treatment.
5. Enlarged anterior row glands
With the increase of age, the incidence of prostatic hypertrophy in men will increase significantly, which can cause men to experience symptoms such as urinary frequency, urgency, and increased nocturia, and in severe cases, dysuria. As long as it does not affect normal life, there is no need to pay too much attention.
3. Please don't step on any of these 4 health misunderstandings
With the increase of age, the functions of the body will gradually decline, and we must pay attention to health preservation at this time. But nowadays, there are many health regimens on the Internet that are unreliable, and taking the wrong way will be counterproductive.
Ke Daozheng, chief physician of the Department of Cardiovascular Medicine of the First Affiliated Hospital of Anhui Medical University, reminded that four health misunderstandings must be avoided in daily life.
1. Put an end to meat
For all groups of people, it is necessary to maintain a light diet, and middle-aged and elderly people with chronic diseases need to pay more attention. But eating light doesn't mean rejecting meat, it's about eating it selectively and in moderation.
It is recommended to consume at least > 12 kinds of food per day and at least 25 kinds per week, including fruits and vegetables, meat, fish, potatoes, miscellaneous beans and whole grains.
2. Adjust the three highs only through diet
After being diagnosed with a chronic disease such as three highs, it is necessary to follow the doctor's instructions to take medication to control the disease, and do not blindly believe in home remedies to control the disease through food, health products, etc., which will not work and will easily bring additional burden to health.
3. Keen to eat health supplements
Many elderly people are very keen on eating health supplements, believing that this can delay aging and prevent diseases. However, many diseases suffered by modern people are "wealth diseases", which are inseparable from long-term excess calorie intake and lack of exercise.
In addition, some people with weak spleen and stomach are difficult to absorb by taking health care products, which will increase the burden on the gastrointestinal tract. Ordinary people only need to maintain a balanced diet to meet their body's needs every day, and there is no need to consume additional health supplements.
4. The more exercise, the better
There is no doubt that exercise is good for health, but only if it is done in moderation.
The principle of exercise for the elderly should be based on suitable for themselves, moderate exercise, you can choose brisk walking, tai chi, running, swimming, etc., it is recommended to do 5~7 times a week, 30~50 minutes each time.
