First of all, it should be noted that not all patients are suitable for drinking more water. People with heart disease, kidney and liver problems are not suitable for the general measure of drinking more water, because drinking too much water will aggravate the condition. Such people had better follow the doctor's advice on how to drink water and how much water to drink. Moreover, drinking more water means 2.5L a day, and it's useless to drink more. There are many reasons why drinking more water can relieve physical discomfort. First of all, when you are sick, your body fluids will be lost. Drinking water can replenish your body fluids. Secondly, drinking water can promote the transport and function of drugs in the body, and also help the body to discharge metabolic waste through excretory organs. Moreover, when free water increases, cell metabolism and other activities are easy to play, and life activities are often more vigorous, so that more antibodies can be secreted and more stress-resistant proteins can be synthesized to defend and repair the body. Moreover, drinking water reduces blood viscosity and promotes many physiological activities. Ah, give a few examples. -The following comes from knowing that water is an important part of the human body, such as blood, lymph and body secretions. The water content in blood is above 90%. After eating, we need the help of water to swallow, digest, transport nutrients and even excrete waste. Water can lubricate joints, prevent dry eyes, help digestion with saliva and gastric juice, regulate body temperature, and take away excess heat in the body through perspiration. Drinking more water can reduce uric acid, prevent gout, reduce urinary calcium concentration and avoid urinary calculi. Our body has about 40 liters of water, and our daily water loss varies according to personal activity and environment. Under normal circumstances, our daily urine output is about 1500CC, plus the water directly evaporated from sweat, skin and feces. , add up to about 2000~3000CC of water loss every day, so it is best to replenish water within this range. Breathing will also lose water. With the increase of workload and temperature, the amount of respiration and perspiration will also increase, and the loss of water will also increase relatively. Fever, vomiting and diarrhea caused by illness can also cause a lot of water loss, so it is necessary to supplement as soon as possible to maintain the balance of water in the body in order to maintain good health. Because losing 10% water is harmful to health, and losing 20% water is dangerous to life. Almost all foods contain water, which is absorbed by the body when it is digested. Besides boiled water, fruits and vegetables are also good water sources. Water is the best medicine. Everyone should drink 8 glasses of water every day (about 2000~3000CC, if the urine color is dark, it means that the water is not enough) to prevent and treat many diseases. Examples are as follows: cold and fever: preventing colds requires adequate sleep, a balanced diet, adequate water and liquid food to supplement the water lost due to fever. Cholelithiasis and kidney calculi: Drink enough water every day to wash away kidney calculi or prevent the occurrence of stones. Gout: Gout is inflammation and tissue accumulation around joints caused by uric acid is too high. Therefore, drink plenty of water every day to prevent crystal deposition caused by uric acid and make uric acid easily excreted from the kidneys. Asthma: Asthma is characterized by chest tightness and dyspnea, accompanied by wheezing and hissing. Patients should drink plenty of water to keep respiratory secretions thin and not sticky. If there is phlegm, it is easy to cough up, and it will not block the bronchus and aggravate asthma. Cystitis: This urinary disease is mostly caused by bacterial infection of urethral orifice, but sometimes it is also caused by infection of kidney and spreads from urine to bladder. Cystitis mostly occurs in women, and patients need to drink a lot of water to wash away infected bacteria in their bodies. Constipation: Drink plenty of water and liquid food to avoid intestinal water loss, eat more fiber-rich food to facilitate excretion, and do enough exercise. People who drink too little or not enough water are not only more likely to get sick, but also more likely to get tired and confused, and it is not easy to eliminate toxins in their metabolism. Office workers who sit in air-conditioned rooms all day are more prone to dry skin and fine lines. For the elderly, children or athletes, if they stay in the sun for a long time, they are likely to have dehydration symptoms such as dizziness, rapid heartbeat, shortness of breath, pallor and blood pressure drop, so don't underestimate the little gesture of drinking water! Remember to replenish the necessary water for your body at any time. However, although drinking water seems to be a very simple action, there are many points to pay attention to: (1) Drinking water after three meals: it is more appropriate to drink water half an hour after meals, but modern people are used to drinking canned drinks and don't like drinking boiled water. But we should also carefully choose canned drinks, among which sports drinks or fruit and vegetable juice are the best, because fruit and vegetable juice can supplement a variety of nutrients, and sports drinks have a proper amount of electrolyte, which is equivalent to the osmotic pressure of the human body and better than water. Recently, light sports drinks have appeared in the market, which is a suitable choice for office workers who don't exercise often to supplement water and electrolytes. (2) Getting up in the morning and drinking a glass of water can be said to be the best hydration time in a day, because drinking water in the morning can immediately wake up the stomach, stimulate peristalsis and prevent constipation. More importantly, after a long sleep, the blood concentration increases. Replenishing water at this time can quickly reduce blood concentration, promote circulation, and make people refreshed and awake. (3) When you sleep with a glass of water before going to bed, you will naturally sweat and lose water and salt unconsciously, but you can't replenish water within six to eight hours of sleep, which is why you will feel thirsty when you get up in the morning. Therefore, it is recommended to supplement water and electrolytes half an hour before going to bed, so that the body can still maintain a balanced state during sleep, and at the same time, the urine concentration can be reduced to prevent the occurrence of stones. (4) Sports drinks contain sodium chloride, which is suitable for supplementing body fluids after sweating or diarrhea. It is not advisable to drink a lot of boiled water at ordinary times, so as not to increase the burden on the kidneys. (5) If you drink mineral water or distilled water instead of tap water for a long time, it may increase your child's chances of tooth decay because there is no fluoride added to protect your teeth. The preventive method is to brush your teeth with fluoride toothpaste. (6) The electrolyzed water for drinking in the market is alkaline water, which is suitable for people with acidic constitution or who usually like to eat meat but eat less vegetables and fruits. Drinking water in the morning is beneficial to water and is one of the seven important nutrients of human body. According to Chinese medicine, water can help Yang Qi and dredge meridians. Modern medicine believes that water is an important component of human tissues, and 60% of adults' weight is water. The metabolism in the body needs water to complete, so it can be said that water is the clear spring of life. When people get old, with the increase of age, the inherent water and intracellular water in the body gradually decrease, resulting in chronic and physiological water loss. This is also one of the reasons why the skin of the elderly is dry and wrinkles increase. Because the skin is dry for a long time, the secretion of sebaceous glands decreases, and the skin's resistance to pathogenic bacteria decreases, which is prone to furuncle, dermatitis, eczema and other skin diseases. In addition, the decrease of water in the elderly can also reduce the normal mucus secretion in the intestine, make the feces stay in the intestine for too long, and the harmful substances produced by bacteria in the feces accumulate too much in the intestine, which will cause headaches, dizziness, listlessness and other symptoms after being absorbed by the human body. Toxins in feces are harmful substances that induce intestinal cancer. Water plays a more important role in the elderly. Scientific research and practice have proved that drinking a glass of water every morning for the elderly and sticking to it have the following benefits for health and longevity. 1. Diuretic effect: Drinking water on an empty stomach in the morning will have diuretic effect within 15 ~ 30 minutes, and the effect is rapid and obvious. 2. Promote defecation: Drinking water in the morning can prevent habitual constipation. Because the gastrointestinal tract is cleaned and cleaned in time, feces will not accumulate and dry. At the same time, drinking water is also a slight stimulation to the gastrointestinal tract, which can promote gastrointestinal peristalsis and facilitate defecation. 3. Detoxification: Many families have the habit of eating a lot at dinner, so the animal protein and salt ingested at dinner enter the body more. Protein, an animal, catabolizes and produces some toxic substances in the body. Drinking water in time in the morning can be excreted as soon as possible by promoting urination. 4. Prevention of hypertension and arteriosclerosis: If you drink a cup of warm water immediately after getting up in the morning, it will help to excrete the sodium chloride you ate in the body the night before. People who usually drink more water and love tea have a lower incidence of hypertension and arteriosclerosis. 5. Prevention of angina pectoris: After a night's sleep, the body loses a lot of water with urine, sweat and breathing, and the blood becomes sticky, and the vascular cavity narrows due to the decrease of blood volume, which often causes acute blood supply insufficiency and even occlusion of the coronary artery supplying blood to the heart. Therefore, angina pectoris and myocardial infarction often occur in the early morning and around 9 am. If the elderly drink a glass of water in the morning, it can replenish water, reduce blood viscosity, dilate and restore blood vessels, thus reducing the occurrence of angina pectoris and myocardial infarction. Drinking water in the morning should be boiled water, and the amount of drinking water is generally around 200 ~ 400 ml. Drinking too much water is not good for the stomach, and it also affects breakfast. Be moderate. People must guard against "drought" in middle age. The drought in nature has caused many disasters to human production and life, and the "drought" in human body will also bring many harms to people's health. Generally speaking, frequent vomiting and diarrhea cause acute "drought" to the human environment, which is easy for people to find and prevent. However, the chronic "drought" in the body caused by the decline or aging of human physiological function is easily ignored by people. Physiological research shows that middle-aged and elderly people are most prone to chronic water shortage in the body. This is because after middle age, the plasma renin and adrenal levels gradually decrease, and the secretion of atrial natriuretic peptide increases, which leads to the continuous loss of sodium ions in the body and reduces the thirst response of the human body to water loss. Usually, insufficient drinking water is easy to cause chronic dehydration. This chronic dehydration will do a lot of harm to middle-aged and elderly people, and sometimes even directly threaten their lives. For example, the liquid content in cataract eyes is high, which will change when the body is short of water, causing degeneration of lens protein, and finally causing lens opacity and decreased vision. The data show that the incidence of cataract in the elderly who have suffered from acute dehydration once before is higher, and the incidence of cataract in the elderly who have suffered from dehydration twice or chronic diarrhea is higher. High blood viscosity is one of the important reasons of cerebral thrombosis. In addition to the "blood turbidity" caused by dyslipidemia, one of the main reasons for high blood viscosity is the lack of water in the body. Among them, water loss at night is the most serious, which strengthens the coagulation and adhesion of platelets, so early morning is the peak of cerebral thrombosis. Arrhythmia is monitored by hemodynamics. When the blood volume is obviously reduced, atrial fibrillation can be induced, and chest tightness, palpitation, dizziness, fatigue and other manifestations appear. Clinicians used overcurrent cardioversion for this kind of patients, but the results were ineffective, but sinus rhythm was restored immediately after rapid intravenous fluid infusion and volume expansion. It can be seen that water loss is one of the bane of arrhythmia. Myocardial infarction is easy to cause myocardial injury due to the decrease of systemic blood volume, cardiac perfusion pressure, myocardial ischemia and cardiac output, and can lead to myocardial infarction in severe cases. Clinically, cases of myocardial infarction caused by acute diarrhea are common. The accumulation of harmful substances in the body and long-term water shortage not only reduce urine output, but also reduce skin function and sweat gland secretion. This will affect the excretion of metabolites in the body, cause harmful substances to accumulate in the body, and cause chronic poisoning of the human body. This chronic poisoning is quite harmful, which can damage various organs and tissues and accelerate human aging. Therefore, people should pay special attention to hydration after middle age. Whether in spring, summer, autumn and winter, it is very important to keep enough water in the body for health and longevity. Experts believe that water intake should be both moderate and timely. Generally speaking, it is better to drink a small amount many times, and drinking water in the morning is better. (China Medical Journal) What did you do this morning? Everyone has his own habits, but good habits directly affect your health. Here, I only recommend five ways to get up in the morning from the perspective of health care. First, get up early. Do you often stay up until the last minute of getting up in the morning? Experts suggest that the way you get up in the morning will affect how you feel all day. If you are in a hurry, you will feel uneasy all day. Therefore, you'd better give yourself enough time to prepare and set the alarm clock a quarter of an hour in advance, so that although you sleep less, your mood will be more stable. If you are depressed, get up at dawn and your depression will be swept away. Second, wash your face. Most people like to use hot water when washing their faces. Actually, hot water is not as good as cold water. This is because cold boiled water is a kind of "degassed water", with little air and great "elasticity", which can easily penetrate into the skin, so that cells can keep enough moisture and appear soft, delicate, shiny and elastic. Especially for middle-aged and elderly people, washing your face with cold water often can not only prevent colds, but also make you radiant and stay young forever. Third, drink water. Drinking water in the morning has unique benefits for the human body. Experts believe that in the process of metabolism, organisms constantly produce some poisons that are harmful to the body. The function of drinking water in the morning is to clean these poisons and keep the intestines clean. Health experts believe that if you want to live a long life, your intestines are always clean. Fourth, exercise. Drink water early and exercise later. At this time, it is better to improve your health. During exercise, the movement of limbs, the acceleration of breathing and the contraction of abdominal muscles make water wash back and forth in the gastrointestinal tract, which is equivalent to a more powerful washing of the gastrointestinal tract, which can wash away some dirt and waste on the gastrointestinal mucosa and help food be digested and absorbed by the human body. At present, many people in our country insist on drinking in the morning, most of which are closely coordinated with physical exercise. After drinking, they go out for activities, some play Tai Ji Chuan, practice Baduanjin, and some take a walk or jog, which has a certain therapeutic effect on their indigestion and constipation. Fifth, breakfast. As we all know, physical exercise can enhance physical fitness, and nutrition is the material basis of physical fitness. Therefore, sports nutrition must be balanced. In a day, getting up early to exercise pays the most energy. From the physiological needs, breakfast is the most important thing in a day. But many people ignore the function of breakfast. Breakfast is very simple, and some even go to work without breakfast. A person has not eaten for at least 12 hours from dinner on the first day to breakfast on the second day, and his stomach is empty. Breakfast determines the sugar level in the blood. If you eat breakfast and work or study at 10 in the morning, your blood sugar will be low, which will seriously affect the functional activities of the five permanent members of the brain. Some people will feel flustered, dizzy, dizzy and even faint. So, not only eat breakfast, but also eat well. Foreign nutritionists disapprove of eating starchy food for breakfast. They think there should be enough protein and fat to achieve a balance between import and export. Only in this way can health be guaranteed. An hour in the morning is worth two in the evening. Insisting on doing exercise in the morning will have many effects on human function, and its significance is no longer a dispensable living habit, but a very beneficial health care measure to prolong life. Reasonable drinking water Some medical schools and research institutions in the United States have formulated a "longevity code", one of which is "drinking water between half an hour before meals and morning 1 hour." The thirst perception center of the elderly brain is slow and insensitive to thirst. If you don't take the initiative to drink water, you will lose water when you are thirsty, which will dry your skin and increase wrinkles. If you drink 5 to 6 glasses of water every day, you can avoid dehydration. It is most suitable to use fresh cold boiled water with natural cooling and temperature of 20℃. Drinking a glass of water in the morning can dilute blood and reduce blood viscosity. Drinking water at 1 hour half an hour before meals can supplement the needs of human cells and help digestion. Drinking water on an empty stomach in the morning is particularly effective. Of course, the elderly should especially prevent drinking a lot of water at one time, so as not to increase the burden on the heart and kidneys.
