"TV eyes" approach you, me and him
Television has long been the most important and largest part of people's entertainment life, and watching TV properly is of positive significance for entertainment, acquiring new knowledge and eliminating loneliness. However, extremes meet, and any excessive behavior will always bring trouble to people and affect their health. Some people say that excessive addiction to TV will make people obese and increase the chances of gallstones, hypertension and diabetes. Recently, it has also been found that if people stare at the screen in front of the TV for a long time, they will be prone to "TV eyes".
The main symptoms of TV eyes are obviously decreased vision, blurred vision, tired and dry eyes, frequent eye drops, dizziness and headache. In severe cases, nausea, vomiting and even temporary blindness may occur. Most students suffer from TV eye diseases, which can reach more than 90%, but some patients are young people in their twenties.
The way to prevent TV eyes is simple, that is, don't indulge in TV; Don't stare at the TV screen Every 15-20 minutes, take your eyes off the screen and blink frequently. Get up and walk every 1 hour 1 minute.
How can we strengthen our vision and avoid the symptoms of blurred vision, swollen eyes and dry eyes? The following simple methods can prevent and treat TV eyes:
1, close your eyes and relax, sit about 15 cm away from the 25-watt desk lamp, and gently shake your head left and right to expose your eyes to warm light.
2, take a sitting position, with the waist as the center, so that the upper body swings left and right.
3. Close your eyes quickly, open your eyes and take a deep breath slowly.
Ten killers endangering human health
1, the toxin in the air-automobile exhaust. The main pollutant in the air is carbon monoxide. Hydrocarbons, sulfur dioxide, lead, mercury, etc. All of them are discharged with automobile exhaust, among which lead is a heavy metal element that seriously harms human health, and can affect organs such as nerves, hematopoiesis, digestion, urine, reproduction, child development, endocrine, cardiovascular, immunity and bones. Seriously affect children's growth and intellectual development, damage cognitive function and brain function, and seriously cause dementia. Mercury poisoning can lead to meningitis, hypokalemia, renal failure and even shock death.
2, gentle killer-non-environmental cleaning agents and toiletries. Inferior and low-priced emulsions generally contain a lot of caustic soda, and surfactants are not added according to the standard. A large amount of phosphate exceeds the standard and contains a large amount of urea, which is extremely harmful to human body. Phosphorus directly irritates the skin, including burning, pain, peeling, itching, chapped and other symptoms. It is a common source of sexually transmitted diseases such as contact dermatitis and diaper rash in infants. Diseases caused by detergent and washing powder poisoning account for 5% of the total outpatient visits in the world every year. Cleaners and toiletries produced by regular manufacturers must meet the national hygiene standards for food safety, with weak alkaline PH and no sodium tripolyphosphate.
3. Toxins in tobacco and wine-nicotine and ethanol. Nicotine is a cancer promoter, and its main components are carbon monoxide, carbon dioxide and acrolein. Compared with the hot smoke inhaled by smokers, the contents of tar and nicotine in the cold smoke exhaled by smokers are 2 times, benzopyrene is 2 times, carbon monoxide is 4 times and ammonia is 50 times. Compared with non-smokers, the incidence of smoking or lung cancer is 8- 12 times higher, laryngeal cancer is 8 times higher, esophageal cancer is 6 times higher and bladder cancer is 4 times higher. Nicotine in cigarettes can poison a mouse, injecting nicotine equivalent to 25 cigarettes can poison a cow, and 20 cigarettes can poison a person. Ethanol, the main component of alcohol, has strong toxic and side effects. Excessive drinking can lead to drunkenness, headache, dizziness, nausea, vomiting, unstable blood pressure, arrhythmia, limb tremor, convulsions, coma, restlessness, loss of consciousness and respiratory arrest.
4. Toxins from drugs-hormones and antibiotics. Long-term medication and improper medication will lead to poisoning and malnutrition, which is called drug malnutrition in medicine. Excessive, excessive and miscellaneous drugs will produce a lot of toxins and endanger health. Long-term use of broad-spectrum antibiotics is easy to cause secondary infection, inhibit the growth of normal intestinal flora, and make other pathogenic bacteria multiply, which will cause vitamin K and vitamin B deficiency in the body and make it easy to catch a cold. Hormone drugs are mainly manifested as neuroendocrine disorder, which is not conducive to protein's digestion and absorption, and sugar can not be converted normally, which contributes to children's obesity and premature development.
5. Toxins from crops-pesticide residues. Pesticides generally enter the human body through the digestive tract, respiratory tract and skin. After most pesticides are applied, their toxic active components or toxic degradation products, derivatives and metabolites remain on the surfaces of vegetables and fruits for a long time. The main impact of BHC and DDT on human body is liver tissue. Animal experiments and human data show that the above two pesticides can cause chromosome aberration of blood cells. It is worth noting that organochlorine can enter the fetus through the placenta and be excreted through breast milk. Fungicides, herbicides and mirex widely used in crops are very toxic. Residues on vegetables and fruits enter the human body, which mainly inhibits the activity of acetylcholinesterase in blood tissue and easily causes a series of manifestations such as neurological dysfunction, sweating, tremor, mental disorder and language disorder. Fertilizer (urea, thiamine, etc.). ) shows that excessive sulfate accumulation in vegetables will form nitrosamines (carcinogens) in human digestive tract.
6, toxins from the bedroom-decoration pollution. A large number of chemicals are used in modern decorative materials, including formaldehyde, ammonia, benzene series, radon and radium. The toxicity and irritation of these pollutants mainly cause symptoms such as dryness of eyes, nose and throat, fatigue, headache, dizziness, memory loss, nausea, skin itching, etc. In severe cases, it can cause infant malformation, leukemia and cancer. The release period of formaldehyde in wood-based panels is 3- 15 years, the release time of oil-in-water coatings is longer than 1 year, and the radioactive substances in artificial marble can last for up to 7 years. The International Agency for Research on Cancer believes that radon is a human carcinogen.
7. Sedative killer-electromagnetic radiation of household appliances. After the computer is started, it will produce electromagnetic radiation, including X-ray, frequency folding, ultra-low frequency, electrostatic field and so on. The ultra-low frequency electromagnetic field generated around the computer will have adverse effects on pregnant women, making the embryo unable to develop normally, deformed or even aborted. Microwave emitted by microwave oven is a kind of high-frequency electromagnetic wave, which is between ultrashort wave and infrared ray and has strong penetrating power. Long-term contact will produce modern diseases such as headache, insomnia, forgetfulness and increased heart rate. Pregnant women and children should stay away from the microwave oven. When the TV picture tube is started, its cathode will emit high-energy electron beam, which will produce X-rays with strong penetrating power, which will greatly reduce negative oxygen ions in the air and make people prone to headache, chest tightness and loss of appetite. Cell phone ultrashort wave is bigger than microwave oven. When people are exposed to radiation with uncontrolled ultrashort wave frequency, fatigue, headache and even disabling cataract will occur. Other electrical appliances with electronic, scanning, radar, vacuum tube and other functions will emit different degrees of electromagnetic radiation.
8. Environmental killers-domestic garbage and used batteries. Free radicals in domestic garbage are the most harmful exogenous toxins to human body. There are tens of thousands of harmful gases and carcinogens produced by oxidation and various chemical reactions in domestic garbage, which are spread by rats, cockroaches, mosquitoes and flies, and are the culprit of cholera, hemorrhagic fever and other diseases. Waste batteries contain a lot of heavy metals such as lead, mercury, cadmium, zinc and manganese, alkaline manganese, waste acid, waste alkali and other electrolyte solutions. Electrolyte of waste batteries can pollute soil and water 15 years.
9. Pollution from unclean water sources-70% of human tissues are composed of water, 80% of blood is water, and water is the source of all life. Domestic sewage, food, processing, papermaking and other industrial wastewater contain a large number of pollutants such as polycyclic aromatic hydrocarbons such as phosphorus, nitrogen, arsenic, chromium, nickel, aniline, benzopyrene and a variety of pathogenic microorganisms, which can induce dysentery, injury, cholera, infectious hepatitis, ascariasis, schistosomiasis, amebic dysentery, cancer and other diseases. Industrial sewage contains a lot of heavy metals, which easily pollutes domestic water and cultivated land, and enters the human body through the food chain, which increases the carcinogenic rate of human body by 10 times and the incidence rate by hundreds of times.
10, the toxin comes from food-junk food with high salt and high calorie. Human waste is the chief culprit of human health and longevity. Regular consumption of junk food can produce more than 600 kinds of bacteria and viruses in the human body, 40 billion to 2 trillion, and the accumulated endotoxin is as high as 6500 grams. It is prone to heart disease, vascular disease, hyperlipidemia, hypertension, diabetes, insomnia, dreaminess, irritability, mental fatigue, yellow skin rust, senile plaque (coffin nail), dryness and dryness. Excessive intake of sodium in salt will accumulate a large amount of cholesterol and other toxins in the blood, leading to poor blood circulation, which is the primary cause of heart disease and cardiovascular and cerebrovascular diseases, and also an important cause of kidney calculi and urinary calculi. Eating high-salt and high-calorie food will lead to cell overload, fat accumulation, poor detoxification, excessive acidity and toxicity, which is the real cause of obesity.
