Looking for health
What is health? Where is health? I take this ancient and eternal proposition to search for the ancient soul.
Qu Yuan said: He pursues the health of personality. When diligence is blocked and loyalty is slandered, throwing white clothes into the river is the answer to "health".
Li Bai said: He pursues the health of culture. When retiring from rivers and lakes, singing about wine and poetry is the interpretation of "health".
Kangxi said: He pursued both physical and mental health. Extensive reading, intensive study of western learning, hunting and harvest, and the prime minister's political affairs are his calls for "health."
Lu Xun said: He pursues the great "health" of the whole nation. When it is found that Chinese people lack not only a healthy body but also a healthy thought, it is the pursuit of "health" to abandon medicine and follow the literature and fight with pen.
I'm a little confused, and I take this proposition with me to search for the life of literature.
Lin Daiyu told me how much she wants to have a healthy body.
Santiago told me how important it is to have a healthy personality.
Jean Valjean told me that a good heart is healthy.
hamlet said: healthy thoughts are the most important.
I walked back to the real world with a formal answer.
I saw Hawking, sitting in a wheelchair, unable to speak, with his wise eyes. He is disabled, but very healthy. Health lies in thinking, fighting and never giving up.
I saw Li Ka-shing, who is rich and simple. He changed from a poor child to a business dajia. His health lies in being rich but not obsessed with money, and giving his big heart to the public.
I also saw them-ordinary people-lend a helping hand when others are in trouble, and put their lives on the line to protect the egrets all over the island
...
Everything is around us.
it suddenly dawned on me that health is like this, including physique, mind, psychology and pursuit. It is great to have one at the same time, but it is also gratifying to have one. It is a way of life for each of us. As long as there is a call for health in our hearts, we will not go astray.
Yes, health is a bright but not dazzling light, a mellow but not greasy sound, a calmness that no longer needs to observe others' words and feelings, an atmosphere that finally stops complaining to the surrounding air, a river that is not rushing, and a height that is not steep ...
Let's visit our own health and sing about its beauty ...

Cut the dried orange peel into shreds, add a little rock sugar, and then slowly boil it with low fire to make a thick orange syrup, which can treat cough! (It is better to eat after three meals.) Scrubbing wooden and bamboo tables and chairs with residual tea leaves can make them smoother.
The residual tea leaves can be dried in the sun and spread in a damp place to remove moisture; After the tea leaves are dried, they can also be put into pillowcases as pillow cores, which are very soft. Water is an indispensable and important substance for human survival. People can live without food for a day, but they can't live without water for a day. However, not all water can be drunk. The following five kinds of water will form nitrite and other toxic and harmful substances to some extent, which will cause certain harm to human body, so people should pay attention to it.
seven kinds of water can't be drunk. 1. aged water: commonly known as "stagnant water", that is, water that cannot be stored for a long time. Drinking this kind of water often will obviously slow down the cell metabolism and affect the growth and development of the body for minors; Middle-aged and elderly people will accelerate aging; The incidence of esophageal cancer and gastric cancer is increasing in many places, which may be related to long-term drinking of aged water according to medical scientists' research.
Relevant data show that toxic substances in aged water also increase with the increase of water storage time. Second, thousands of boiling water: Thousands of boiling water is water that has been boiling on the stove for a night or a long time, as well as water that has been boiled repeatedly in electric water heaters.
Because this kind of water is boiled for a long time, the content of non-volatile substances in the water, such as heavy metal components such as calcium and magnesium, and nitrite is high. Drinking this water for a long time will interfere with people's gastrointestinal function and cause temporary diarrhea and bloating; Toxic nitrite can also cause hypoxia in the body, and in severe cases, it will lead to coma, convulsions and even death.
third, boiler water: boiler water is the leftover boiler water such as steamed buns, especially the boiler water that has been used repeatedly for many times, and the concentration of nitrite is very high. Drinking this water often, or cooking porridge with this water, will cause nitrite poisoning; Scale often enters the human body with water, and it can also cause digestive, nervous, urinary and hematopoietic diseases, and even cause premature aging.
fourth, the water that can't be boiled: the tap water that people drink has been disinfected by chlorination. Thirteen kinds of harmful substances can be separated from the water treated by chlorine, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects.
When the water temperature reached 9℃, the content of halogenated hydrocarbons increased from 53 micrograms per kilogram to 177 micrograms, which was twice as high as the national hygienic standard for drinking water. Experts point out that drinking unboiled water increases the possibility of bladder cancer and rectal cancer by 21%-38%.
When the water temperature reaches 1℃, these two harmful substances will be greatly reduced with the evaporation of steam. If boiling continues for 3 minutes, it is safe to drink. 5. Re-boiled water: Some people are used to re-boiling the remaining warm water in the thermos bottle before drinking, in order to save water, coal (gas) and time.
but this "saving" is not worth taking. Because water burns and burns, the water evaporates again, and nitrite will rise. If you drink this water often, nitrite will accumulate in the body and cause poisoning.

If your eyes are dry and itchy, close them and rest for a few minutes before opening them. Never soften them with your hands. If there is no improvement, you must seek medical attention, because it may be caused by other infections.
Daily eye care and drink plenty of water: Especially in air-conditioned offices or rooms, special attention should be paid to the supplement of water, which can improve the dry state of eye mucosa. Eye drops, physiological saline, artificial tears: people who wear contact lenses often rely on such eye drops to protect their eyes; Some people buy some eye drops in the pharmacy to prevent dry eyes, but it is safer to pay attention to the source of the liquid medicine, which is best prescribed by a doctor.
Because most eye drops or artificial tears are added with preservatives or fungicides for the convenience of storage, the average person should not have much problem in using them, but it's hard to say if you are allergic. Cold and hot compress: when eyes are tired, you can use ice compress and hot compress alternately, but you can't ice or press your eyes. The same is true for hot compress, which lasts less than 5 minutes at a time and can match your eyes.
