Health knowledge in the summer of 2022

Speaking of intense heat, you may feel strange, but it is one of the 24 solar terms in China, which belongs to summer. This time I sorted out the knowledge of summer health care for your reference.

Health care knowledge in summer

Keep your head clear and calm in summer, and pay attention to clearing away heat and fire.

In summer, when the climate is hot, people are easily agitated and tired. In self-maintenance and exercise, we should take care of the heart yang according to the five internal organs and the heart in summer, and keep calm to ensure the vigorous heart function, so as to conform to the principle of "nourishing yang in spring and summer". "LingShu? At the beginning of all diseases, it is said that "honesty will hurt the dirty" because the emotional activities of the human body are closely related to the five internal organs and have certain rules. Different emotional stimuli will hurt different viscera and produce different pathological changes. Chinese medicine advocates a word "ping", that is, under no circumstances can there be excessive behavior. When you are overjoyed, you will be sad. If you are heartbroken, you will be distracted, unable to concentrate, and even insane. The heart is the master of the five internal organs, and all life activities are the concentrated expression of the functions of the five internal organs, which are dominated by the heart, and there is a saying that the heart shakes the five internal organs. But the damage to the mind will inevitably involve other viscera. Emotionally speaking, happiness is an inner ambition. This kind of "happiness" is to relieve the tense mood, make the mood comfortable, and make the qi and blood calm. Therefore, it is also the same reason that summer health care focuses on the word "peace of mind".

Summer is also a season with frequent digestive tract diseases, so bad habits such as improper diet, unclean diet and partial eclipse should be changed in diet conditioning. Eat moderately. Hunger leads to insufficient food intake, lack of chemical sources, leading to insufficient qi and blood, causing physical fatigue and emaciation, weak vital qi, decreased resistance and other diseases; Full appetite will exceed the digestion, absorption and transportation functions of the spleen and stomach, leading to diseases that damage the spleen and stomach, such as food accumulation, abdominal distension, putrefaction and pantothenic acid, anorexia, vomiting and diarrhea. "Su Wen?" "Bilun Tablet" says: "Diet doubles, stomach hurts", which means diet should be controlled.

Unclean diet in summer is the culprit of many gastrointestinal diseases, such as dysentery, parasites and other diseases. If you eat spoiled and toxic food, it will also lead to food poisoning, causing abdominal pain, vomiting and diarrhea, and even coma or death.

Dietary addiction is one of the causes of malnutrition, and only proper dietary adjustment can ensure the nutrition needed by the human body. The diet tends to be too cold and overheated, and the five flavors are biased.

Eating too much will damage the yang of the spleen and stomach, cold and dampness can cause abdominal pain and diarrhea, partial eclipse can cause gastrointestinal heat accumulation, thirst, abdominal distension and pain, and constipation will eventually become hemorrhoids; The deviation of five flavors means that people's spiritual qi and blood are all bred by five flavors, which correspond to the five internal organs, such as sour entering the liver, bitter entering the heart, sweet entering the spleen and salty entering the kidney.

If you like a certain food for a long time, it will make the function of viscera rise and fall, and over time it will damage the internal organs and cause diseases. If it is salty, the qi and blood will stagnate and the face will be dull; Eating more bitterness will make the skin dry and the hair fall off; Eating too much spicy food will make tendons tense and nails wither; Eating too much sour taste will make the skin tight and shrink, and the lips will be dry and thin. If you eat too much sweets, your bones will hurt and your hair will fall off easily. What is important is that excessive hobbies will not only lead to malnutrition, but also hurt the spleen and stomach and other viscera, leading to beriberi, night blindness and gallstones.

Therefore, I suggest that five flavors (sour, bitter, sweet, pungent and salty) should be appropriate in diet therapy. Usually, you don't have a partial eclipse, and you don't eat when you are sick. Such as "1000 yuan for the party?" "Preface to the Sky" said: "Don't eat if you don't want to be extremely hungry, and don't eat too much; Don't drink too much if you don't want to be extremely thirsty. Eating too much will accumulate, and drinking too much will turn into phlegm. "When you are hungry and thirsty, you are most likely to drink too much and eat too much. Therefore, when you are thirsty, you should chew slowly. In addition, don't force yourself to eat or overeat when you have no appetite. Tao Hongjing, a doctor in the Liang Dynasty, pointed out in the Book of Health Preservation: "If you are not thirsty, you will be bloated, and if you are not hungry, you will be tired. "

What do you plant in summer?

The signs of hot summer are plum blossom and autumn. This means that the rainy season in the Jianghuai basin is coming to an end, and summer begins, and the temperature rises and enters the summer drought period. However, when North China and Northeast China entered the rainy season, tropical cyclones were active frequently, and the number of tropical cyclones landing in China began to increase. What to plant after the light summer: pay attention to drought resistance in the south and flood control in the north. Crops all over the country have entered a vigorous growth period, and it is necessary to strengthen field management.

1, harvesting wheat in the north

In addition to harvesting winter and spring wheat crops in northeast and northwest China, agricultural production is mainly busy with field management.

2. Early rice ripens, middle rice heads and late rice tillers.

Early rice is in the late filling stage, and early-maturing varieties should be harvested before the heat, and the field should be kept dry, moist and dry. Mid-season rice has entered booting stage at jointing stage, so it should be topdressing panicle fertilizer according to its growth situation to promote large panicle and more grains. The single-season late rice is tillering, so tillering fertilizer should be applied as soon as possible. Two-night seedlings should be protected against pests and diseases, and "marriage fertilizer" should be applied 5 to 7 days before planting.

3. Cotton blooms and bears bolls

"It's hot in summer, and the cotton keeps pruning." In most cotton areas, cotton began to blossom and boll, and its growth was the most vigorous. At the same time, old leaves should be pruned and raked in time to coordinate the distribution of nutrients in plants, enhance ventilation and light transmission, improve the microclimate of the population and reduce the shedding of buds and bolls. High temperature in midsummer is the season when aphids, red spiders and other pests flourish, and timely prevention and control of pests and diseases is another important link in field management.

4. Shallow summer precipitation is beneficial to rice growth.

Plum rains in the Jianghuai basin have ended one after another, and the southeast monsoon rainy season from the Pacific Ocean has begun to appear in the vast areas north of Huaihe River and Qinling Mountain in eastern China, with obvious increase in precipitation and relatively concentrated rainfall. South China, Southwest China and Qinghai-Tibet Plateau are also in the southwest monsoon rainy season from the Indian Ocean and the South China Sea. However, under the control of subtropical high, the middle and lower reaches of the Yangtze River are generally hot and rainy, with frequent droughts in summer, which has a great impact on agricultural production. It is very important to store water as soon as possible to prevent drought. The farmer's proverb says, "When it rains, there is rice in the pot." At this time, thunderstorms, tropical storms or typhoons bring precipitation, which is very beneficial to the growth of crops such as rice, but sometimes it also has adverse effects on dry crops and vegetables such as cotton and soybeans.

Prevention of crop disasters and bad weather in Shanghai

The western part of South China enters the season with the most rainstorm, and the number of rainstorm days in July and August can account for more than 75% of the whole year, usually about 3 days. Mountain torrents often occur in places with large relief, and even cause mudslides. However, in the eastern part of South China, due to the frequent control of subtropical high, the weather is sunny and hot, and after experiencing a slight summer heat, it began to enter the summer drought period. The climatic characteristics of drought in the east and waterlogging in the west in most parts of southern China have a great relationship with agricultural abundance and waterlogging, so we must take measures to ensure the harvest of drought and waterlogging as soon as possible to minimize the harm. At the same time, the number of thunderstorms entering all parts of South China will also increase significantly. Thunderstorm is a disastrous weather phenomenon, often accompanied by strong winds, heavy rain and sometimes hail, which is easy to cause disasters and must be prevented.

Principles of summer health preservation and solar terms

1, pay attention to food hygiene, and the diet should be light and moderate.

The rainy and high temperature in summer make the digestive tract diseases more frequent in summer.

Therefore, this season's diet, we must pay attention to food hygiene, diet should be moderate, not overeating, excessive; And the diet should be light and nutritious.

2. Meditate and nourish your heart

In summer, when the weather is hot, people tend to be restless, sleepy and lack of energy. Therefore, according to the characteristics of this season, in terms of health care, we should maintain the heart according to the corresponding relationship between the season and the five internal organs.

The heart is the head of the five internal organs. It is said that when there is a heartbeat, the five internal organs will shake, so the maintenance of the heart is particularly important. Chinese medicine believes that calmness can relieve tense emotions, make people feel comfortable and ease their qi and blood; It not only contributes to the vigorous heart function, but also conforms to the principle of nourishing yang in spring and summer. Therefore, summer should be calm, calm and naturally cool.

3. Don't be greedy, take more baths and eat more cold food.

When the weather is hot, people like to eat cold drinks. Ice cream, ice cream and iced drinks are very popular. Some people take a bath as soon as they come back from outside, and they also like to take a cold bath.

As everyone knows, these are very unhealthy, and it is easy to cause physical discomfort or bury health risks.

Intimate tip: the climate is hot, sweating is much, consumption is large, and fatigue is added, so don't neglect the maintenance of your body.

4. It is advisable to stay up late and get up early in summer.

This is one of the precautions for keeping in good health in summer, and you should not be careless.

Summer is characterized by long sunshine hours, early dawn and late darkness. Therefore, people's daily life and schedule should be adjusted accordingly, and it is better to go to bed late and get up early. It is best to get up regularly to protect the biological clock from being affected.

In summer, you should follow the principle of getting up regularly. Although individuals vary greatly, most people may go to bed at night 10-1 1 and get up at 5: 30 -6: 30 in the morning. Take a nap half an hour after lunch. In addition, the time for three meals and exercise, brain use and leisure should be clear.

5. Don't go shirtless in summer clothes.

In life, some people like to go topless and enjoy the cold in summer, thinking it's cool to go shirtless. In fact, it may not be so. When the temperature approaches or exceeds the body temperature, the shirtless person will feel hotter rather than cooler.

Because human body temperature regulation depends not only on skin evaporation, but also on skin radiation. When the outside temperature exceeds 37℃, the body temperature mainly depends on skin evaporation to dissipate heat; When the temperature continues to rise, the skin will not only be unable to dissipate heat, but also absorb heat from the external environment, making people feel more sultry.

6. Go out and do a good job in heatstroke prevention and cooling.

Heatstroke is a common disease in summer, and the weather characteristics in summer are more prone to heatstroke. Therefore, when going out, you must do a good job of heatstroke prevention and cooling, bring umbrellas, sun hats and other tools, drink plenty of water, and try to avoid going out when the sun is hot in the afternoon.
