Drink high sugar drinks and easy to heat hot water needed diversification
The heat of summer, in time for the hydration of the body is also important, most people think water filling water works best, and the United Kingdom recently, a new study shows that replenishment effect of milk and other drinks better than water. Experts caution that summer water also needs to be diversified, don’t wait to be thirsty to drink water. High temperature days because many people are thirsty, like sugary drinks or cold beer. But, in fact, high sugar drinks and alcoholic beverages can make the body lose more water at high temperatures would not be suitable for a lot of drinking. Experts suggested that the high temperature days heat stroke prevention, diet food high less high-fat food, reduce calorie intake, eat more fruits and vegetables, eating more milk, yogurt, drink-food soup, tomato soup, bean soup, soy milk, plum juice, white fungus soup such as water yield.
Dog days, across into high temperature heat mode, because the sharp increase in stroke patients attending hospital emergency department. The third affiliated hospital of Guangzhou Medical University Emergency Department Deputy Director Chen Dexiong reminders, high temperature days because many people are thirsty, like sugary drinks or cold beer. But, in fact, high sugar drinks and alcoholic beverages can make the body lose more water at high temperatures would not be suitable for a lot of drinking. In addition, in summer, many people worry about indoor air conditioned children catch cold, this is error, there is no open air children are more prone to heat stroke.

Moist heat more heat than dry heat, caused by severe heat stroke heat exhaustion heat stroke
Chen Dexiong introduced, known as heat stroke, refers to a long period of high temperatures, high humidity and heat under the action of radiation, causing dysfunction of thermoregulation, heat sink function, resulting in water and electrolyte metabolism disorders and dysfunction of the nervous system.
Chen Dexiong pointed out that high temperature environment is the main factor leading to heat exhaustion. When at room temperature over 35 degrees, high humidity and poor ventilation environments or engage in heavy manual labor for a long time under the heat radiation and strenuous exercise, excessive exposure to the Sun and lack the necessary cooling measures have a heatstroke may occur. Under the same conditions of temperature and heat more easily than dry heat causing heat stroke.
Chen Dexiong said, according to the severity of the symptoms of heat stroke, precursors can be divided into heat stroke, light heat stroke and severe heat stroke.
Early sign of heatstroke after a period of working in a high temperature environment, a slight dizziness, headache, tinnitus, Vertigo, thirst, weak and unstable walking. Body temperature is generally not more than 37.5 degrees Celsius. Replenish fluids and salts, symptoms can be restored.
Mild heat exhaustion means in addition to the above symptoms, fever, skin flushing, chest tightness, dry heat, or pallor, nausea, vomiting, sweating, blood pressure, pulse and other early signs of peripheral circulatory failure. Body temperature 38 ℃, time, supplemental electrolytes, water cooling treatment, hours can be restored.
Severe heatstroke in addition to the above symptoms, often collapsed or ventilation after Khan, irritability, thirst, scanty urine, muscle pain and weakness. Severe heat stroke can be divided into 4 types:
1. heat cramps: thirst after sweating and drinking lots of water, lack of sodium supplements and disease, characterized by limb clonic spasms and pain, and sometimes abdominal pain can also occur.
2. heat exhaustion: more common in the elderly and infirm, and in severe cases due to dehydration or hypernatremia causes circulatory collapse. Characterized by headaches, dizziness, palpitations, pallor, nausea, vomiting, thirst, body temperature is normal or slightly higher.
3. sunstroke: heat, temperature rises than the nervous system symptoms, severe headache, nausea, vomiting, fainting, or blurred mind, and even unconscious twitch. Quadriparesis, urinary retention and positive pathological reflex. Severe Central respiratory, circulatory failure, Mydriasis, abnormal EEG.
4. heat stroke: characterized by high fever, anhidrosis, disturbance of consciousness, multiple organ function failure, occurs in the labour or exercise under high temperature environments.
High temperature days indoors without air conditioning against heat stroke, high-sugar drink more drink more water
Chen Dexiong pointed out that prevention of heat stroke, first to develop good habits of drinking water, don’t wait to be thirsty to drink water because thirsty bodies already were short of water. Usually pay attention to eat fresh vegetables and fruits. “Paying particular attention is that alcoholic drinks and sugary drinks can make the body lose more water at high temperatures would not be suitable for a lot of drinking. ”
Chen Dexiong also warns of high temperature days should reduce outdoor exercise, avoid prolonged driving, parking, avoid leaving children unattended in the car. If you want to go out, to avoid the noon-time and sunscreen, Dai Kuan hat or use umbrellas and wearing dark glasses, wearing a thin, loose, light clothing. Meanwhile, to ensure adequate sleep, can cause the brain and various systems of the body are relaxed, but also to prevent heat stroke.
“A lot of parents worry about kids cold, afraid to open air. In fact, so much easier to heat stroke. “Chen Dexiong said hot weather should be indoors, so, may wish to take some air conditioning, but the temperature is not too low, at 26 degrees. The elderly, children, and the heart-lung Foundation, mental disorder patients most prone to heat stroke symptoms, be sure to take a look.
Milk, orange juice, fruit and vegetable soup, food, seeds and white fungus soup, water effect is better than boiled water
Many people have heard of “should drink 8 glasses of water a day” proposal, especially the summer sweating more need to drink plenty of water, but just drink water effect is best?
In the United Kingdom in a new study, United Kingdom water studies, Loughborough University expert Ronald · Dr j Maughan and his colleagues to follow suit “glycemic index” has identified 13 common drinking water index. Experimental study at the age of 72, 25 per cent of male participants to drink 1 liter of boiled water, lodged in its body water content after two hours (no water excreted through the urine) is 1.0, in a similar method to individually assess the other drinks. If they score higher than 1.0, then the drink body water retention rate is higher than water, whereas the excretion rate is higher than water. Results show that oral re-hydration solution (such as electrolyte liquid, often used to treat diarrhea caused by severe dehydration), skim milk, whole milk and orange juice “water index” significantly higher than that of water, three drinks “water index” is about 1.5, orange juice is 1.1. Research also found that the amount of caffeine-containing beverages, sweet drinks, soda water index and water makes no difference.
China Agricultural University food science and nutrition Engineering College Associate Professor Fan Zhihong think, this research results is reasonable of, water drinking Hou will soon was stomach absorption into blood, last from kidney excretion out, water molecular in human in the of stay time more short, and drinks in the contains of few Pro-water compounds (like protein, and sugar, and starch, and plant glial), and electrolytic quality can adsorption many water molecular, block they in stomach in was fast absorption, can let water molecular of absorption speed variable slow, while put more water with to intestinal even colorectal among In the body longer retention time, so more water. Assuming, of course, is the osmotic pressure of hydrating drinks cannot be higher than the osmotic pressure of body fluids, lots of sugar, salt and protein will be thirsty.
Fan Zhihong proposal for a long drive, and milk both hungry and quench your thirst, is a convenient choice. But under normal circumstances, does not recommend using milk instead of water to fill the water completely, because they contain fat should not be neglected, a lot of drinking easier to have the risk of obesity. The Chinese residents ‘ dietary guidelines recommend, milk intake to 300 grams per person per day is advisable rather than drinking milk, then eat some fruits and vegetables to supplement the water. In addition, index of sweet drinks, soft drinks, water and water of similar, but they tend to be higher sugar content, is also not recommended to drink a lot of it.
Chen Dexiong recommends that preventive diet food high less high fat diet, reduced calorie intake, can have tomato soup, bean soup, milk, sour plum soup and other. Fan Zhihong also said there is a lot of food also has a good moisturizing effect.
Fruits and vegetables. Fruit water content reaches above 85%, it the moisture present in the cells, and exists simultaneously with the pectin and potassium ions, a slow release in the body. Low sugar fruits, such as tomatoes, cucumbers can direct raw vegetables without salt, is water quality.
Food soup. With various grains cooked food soups contain starch and dextrin, can allow water to slowly through the gastrointestinal tract, moisten the mucous membranes and helps water. In addition, whole grains are rich in b vitamins and potassium can also make up for nutrient losses from sweating. Suggested that you drink in the summer grain such as millet soup, bean soup soup.
White fungus soup. In addition to the starch, white fungus soup also contains vegetable gum – polysaccharides from Tremella fuciformis Berk, it can bind large amounts of water, cooked soup is sticky, throat and digestive tract mucosa is fully moist. In addition, the polysaccharides from Tremella fuciformis Berk can’t be digested, so will the rest of the water directly into the large intestine, increased stool moisture, to avoid drying.
Fan Zhihong also reminded, summer of appetite, inadequate protein intake can increase the milk intake, the special advocate “milk + fruit” combination instead of cold drinks. Compared to yogurt, ice cream, ice lollies, sweets and ice-cream high osmotic pressure, contain more sugar and fat to be reckoned with, after the meal is just cool the mouth, not only fail to quench their thirst, but will accelerate the thirst. Chen Dexiong caution, hot days try to avoid drinking a large quantity of chilled drinks, so as not to cause stomach cramps.
