Why should the elderly drink more water? 1, sedation.
When you are upset and emotionally unstable, slowly drinking a small amount of water has a certain calming effect.
2. Beauty effect
Drinking more water at ordinary times can make the tissues and cells of the body have enough water, make the skin tender, moist and shiny, and reduce brown fat or wrinkles.
Step 3 lubricate joints
Water is a lubricant for joints and muscles, which has a certain buffering effect on human tissues and organs. In particular, it can reduce joint friction and is beneficial to activities.
4. Prevent cataract formation
The liquid content in human eyes is high. When the body is short of water, biochemical changes will occur, which will lead to protein degeneration of the lens of the eyes, which will eventually lead to lens opacity and decreased visual field.
5, the effect is strong
Water has great solubility and ionization ability, which can make water-soluble substances in the body exist in dissolved state and electrolyte ion state, which is helpful to activate chemical reactions in the human body and increase vitality.
6. Reduce fat and lose weight
Experiments show that drinking 8~ 12 cups of cold boiled water every day can make obese people lose 0.5 kg per week. Because cold water is easily absorbed by tissues, it can consume heat, shrink blood vessels and slow down the absorption of fat.
7. Relieve constipation
Get up every morning and drink a large glass of light salt and cold water. Because of the lack of physical activity on an empty stomach, salt water is not easily absorbed by the stomach and small intestine, and soon enters the large intestine, which not only stimulates the peristalsis of the intestine, but also dilutes the feces, which is beneficial to defecation.
8. Cough and expectoration
In the elderly with respiratory diseases, it is often difficult to cough up phlegm, which is related to the viscosity of phlegm besides the lack of coughing power. Sputum is too thick, and it is not easy to cough up if it sticks to the trachea or bronchial wall. Diluted sputum is easy to be discharged after hydration.
9, prevention and treatment of indigestion
Lack of water in the elderly will lead to insufficient secretion of digestive juices such as gastric juice, saliva, bile and pancreatic juice, which will not only affect the digestion and absorption of food, but also hinder the dissolution and absorption of food nutrients. Only by drinking water scientifically can we strengthen the stomach and promote digestion.
10, beneficial to breathing
People need water to breathe. Proper drinking water can keep the lung tissue moist, and the lung function can be relaxed freely, so that oxygen can be inhaled and carbon dioxide can be discharged smoothly. In addition, water is beneficial to carry nutrients in blood and deliver oxygen to cells, which is beneficial to the whole body.
1 1, protect your eyes.
Drinking water can help your eyes have enough tears. When hot objects are close to the eyes or work in the sun, tears will form a thin layer of water vapor under the action of high temperature. This kind of water vapor plays a role in preventing high temperature conduction, which will reduce the degree of eye injury.
12, cancer prevention
Lack of water and time in the elderly not only reduces urine output, but also reduces skin function and sweat gland secretion. It will also affect the excretion of metabolites in the body, causing harmful substances to accumulate in the body, which is easy to cause urinary calculi, breast cancer, urinary cancer and other diseases.
13, protecting renal function
Adequate body fluids can reduce the concentration of metabolites in the body and reduce kidney damage. It is particularly important that the elderly should always replenish water to avoid excessive calcium concentration in urine, which can prevent kidney calculi. In addition, once the urinary system infection is opened, such as timely hydration? Internal washing? At the same time, it can also play a role that antibiotics often can't play.
14, anti-aging
The imbalance of water in the body is the main cause of aging. Water is an important substance to provide energy in living beings, and it is also the transmission medium of various nutrients. If it is lacking, it will hinder the flow of liquid in the body, slow down metabolism and make people start to age. At present, there is no panacea for aging, but if we can stop or delay the process of dehydration of organisms, we can continue life.
The correct way of drinking water for the elderly, drinking water in the morning can prevent diseases.
After waking up, if you drink two glasses of water on an empty stomach, it can not only make up for the nutritional deficiency caused by physiological dehydration, but also reduce the viscosity of blood, accelerate blood circulation and promote the rapid discharge of metabolic wastes such as feces and urine. It has a short-term effect on preventing cardiovascular and cerebrovascular diseases such as cerebral embolism, cerebral thrombosis, hypertension, arteriosclerosis and angina pectoris, as well as urinary tuberculosis and urinary tract infection.
The old man missed the cup.
Some elderly people like to drink plenty of boiled water or other drinks after physical exercise and housework. This is? Emergency irrigation? The new drinking method will suddenly increase the burden on the heart, make the blood concentration suddenly decrease, cause the heart to beat too fast, cause palpitation and dizziness, make heart patients more prone to danger, and suddenly dilute gastric juice, destroy gastric mucosa, and affect appetite and stomach function.
Salt water and tea are the most thirst-quenching.
Sweating in summer takes away salt, vitamins and trace elements such as potassium and magnesium. If it only drinks boiled water, it will not only fail to enter blood vessels and stay in cells normally, but also easily penetrate into sweat glands and bladder and be excreted quickly, which will not only quench its thirst, but also cause discomfort such as fright and dizziness. For example, adding a small amount of salt when drinking boiled water will keep the body nutritious and have the effect of quenching thirst.
Drinking tea in summer can not only supplement nutrients, lost vitamins and other things necessary for the human body, but also promote fluid production to quench thirst, refresh the mind, enhance appetite, and have the functions of detoxification and sterilization.
According to experts' research, not drinking water before going to bed at night will lead to an increase in plasma concentration, an increase in blood viscosity and an overactive platelet aggregation, thus promoting thrombosis in the body. For the elderly or people with cardiovascular and cerebrovascular ischemic diseases, drinking a glass of water before going to bed at night can prevent fatal infarction.
Many elderly people are not used to drinking water before going to bed and are afraid to get up at night to urinate. In fact, the bladder of the elderly is atrophied and its capacity is reduced, so they have to get up at night without drinking water. Old people's kidney contractile function is decreased, and they have too much urine at night, which leads to insufficient water in the body, thick blood, and increased blood flow resistance in the heart and brain, which is easy to cause cardiovascular and cerebrovascular diseases. For the elderly with cardiovascular and cerebrovascular diseases, due to the changes of intima, blood viscosity is high, which is easy to form ischemic stroke, and water shortage at night makes this risk even greater. Therefore, drinking water in the middle of the night is very important.
Drinking a glass of water after getting up can make the blood circulate normally and prevent diseases such as hypertension, cerebral thrombosis and myocardial infarction.
Running after drinking water is more beneficial. Water can keep the gastrointestinal tract clean, help the liver to detoxify, improve renal function and endocrine function, improve immune function, and prevent colds, pharyngitis, arthritis and some skin diseases.
