Middle-aged Warning

When people reach middle age, they must be on guard against "drought". Droughts that occur in nature cause many disasters to human production and life. If a "drought" occurs in the human body, it will also bring many harms to people's health. Generally speaking, frequent vomiting and diarrhea cause acute "drought" in the internal environment of the human body, which is easy for people to detect and prevent. However, chronic "drought" within the body caused by the decline or aging of physiological functions is very likely to be overlooked by people. Physiological research shows that middle-aged people are most prone to chronic dehydration in their bodies. This is because after middle age, the levels of plasma renin and adrenaline in people progressively decline, and the secretion of atrial natriuretic peptide increases, which leads to the continuous loss of sodium ions in the body, reducing the body's thirst response to water loss. Insufficient water intake on a regular basis can easily cause chronic dehydration. This chronic dehydration can cause many harms to middle-aged people and sometimes even directly threaten their lives. For instance, in cataracts, the fluid content in the eye is relatively high. When the body is dehydrated, biochemical changes occur, causing denaturation of the lens proteins and eventually leading to lens opacity and vision loss. Data shows that elderly people who have experienced one acute dehydration in the past have a higher risk of developing cataracts, and those who have had two dehydrations or chronic diarrhea have an even higher incidence of cataracts. High blood viscosity is one of the important causes of cerebral thrombosis. In addition to causing "blood turbidity" due to abnormal blood lipids, a major reason for excessively high blood viscosity is water deficiency in the body. Among them, water loss is most severe at night, which enhances the cohesion and adhesion of platelets. Therefore, the early morning is the peak period for the incidence of cerebral thrombosis. Arrhythmia can be monitored through hemodynamics. When blood volume significantly decreases, it can induce atrial fibrillation, presenting symptoms such as chest tightness, palpitations, dizziness and fatigue. Clinicians had previously administered electric shock rehydration to such patients, but the results were ineffective. However, after rapid intravenous fluid replacement and volume expansion, sinus rhythm was immediately restored. It is evident that water loss is one of the main causes of arrhythmia. Myocardial infarction is caused by a reduction in systemic blood volume, a decrease in cardiac perfusion pressure, myocardial ischemia, and a decrease in cardiac output. Therefore, it is prone to cause myocardial damage, and in severe cases, it can lead to myocardial infarction. Clinically, cases of myocardial infarction caused by acute diarrhea are not uncommon. Chronic dehydration due to the accumulation of harmful substances in the body not only reduces urine output but also weakens skin function and decreases sweat gland secretion. This affects the excretion of metabolic products in the body, causing harmful substances to accumulate and leading to chronic poisoning. This kind of chronic poisoning is quite harmful. It can damage multiple organs and various tissues and accelerate human aging. Therefore, people in middle age should pay special attention to replenishing water. No matter the season, maintaining sufficient water in the body is of great significance for health and longevity. Experts believe that water intake should be both moderate and timely. Generally speaking, it is better to drink water in small amounts frequently, and drinking water in the early morning is even more effective. With the continuous enhancement of competitive awareness, many middle-aged people work and study efficiently in the tide of the market economy, remaining in a highly tense mental state for a long time and "enduring" it. Little do they know that "enduring more" is a major enemy of health. For your health and the happiness of all the passengers, it is suggested that you do not "struggle hard". When people reach middle age, due to the heavy workload, especially those in the fields of culture, health, education, journalism and various mental workers, it is advisable to stay up late from time to time and make up for it with a nap the next day. This will not cause much harm to their health. If one works hard for a long time and stays up late for a long time, it can lead to the occurrence of diseases such as neurasthenia, ulcers, hypertension and coronary heart disease caused by excessive tension of the nervous system. Long-term lack of sleep can also cause brain damage and accelerate premature aging. Some middle-aged people, due to their busy work, intense study or business, often don't even have time to take a sip of water for a long time. Skipping breakfast is a common occurrence. If this continues for a long time, it can lead to "water deficiency syndrome", which may cause cerebral thrombosis and urinary calculi. Frequent hunger without eating can also cause gastric ulcers, induce hypoglycemia, and even lead to coma and shock. On the contrary, frequently eating without discrimination and overeating is even more detrimental to health. Therefore, only by eating meals at regular intervals and in fixed amounts can the brain's functions be fully exerted, and the abilities of memory, comprehension, thinking and analysis be kept in a relatively ideal state. Civilized, relaxing, healthy and moderate entertainment activities can regulate one's nerves, cultivate one's sentiments and be beneficial to health. However, excessive play can lead to excessive consumption of vitamin A in the body, resulting in decreased vision and nervous fatigue. If one listens to manic music for a long time, it will cause excessive tension in the eardrum and affect hearing. Playing video game consoles for a long time will lead to "game console syndrome". Playing cards, chess or mahjong all night long will consume too much mental and physical energy, be harmful to the body and mind, and affect health. Therefore, when having fun, one should also know when to stop and pay more attention to civilized elegance and a relaxed and comfortable atmosphere. (Jingyi
