Warning! Passive smoking seriously affects adolescents' reading and reasoning ability.

WASHINGTON, Jan. 5 (Xinhua) -- A study in the United States found that children and adolescents exposed to smoking can have their reading and reasoning skills affected even if they passively inhale even a small amount of smoke.

Researchers at Cincinnati Children's Hospital in Ohio, USA, surveyed 4,400 children between the ages of 6 and 16 in the latest issue of the journal Environmental Health Outlook.

In the study, researchers measured the level of cotinine in the blood of these children. Cotinine is a by-product of nicotine entering the human bloodstream and is therefore a measure of the concentration of inhaled tobacco. The researchers also tested the children on reading, math and reasoning skills.

It was found that the higher the level of cotinine in the children's blood, the lower the score on the test. Not only that, but even children with very low levels of cotinine in their blood have their reading and reasoning skills affected.

But researchers don't know why passive smoking causes children to score low on aptitude tests. Perhaps passive smoking leads to a decrease in oxygen inhalation, they suggest. **。

No, there is a high chance of getting lung cancer.

I believe that many men like to smoke in life, and even many teenagers smoke in order to be cool, in fact, smokers also know that smoking is harmful to health, according to some studies, smoking is the most obvious is to cause neurasthenia, of course, neurasthenia is not only caused by this reason, there are many reasons for neurasthenia, see the specific introduction below. ◆1.Smoking Smoking is known to be harmful to health, but its effects on the central nervous system of the brain are often overlooked.

Although a small amount of smoking can increase the excitatory process of the brain, it weakens the inhibition process and disrupts the dynamic balance of the two, while a large dose of smoking will cause the cranial nerves to be inhibited. ◆2.Alcoholism The main ingredient in alcohol is alcohol, which is medically an anesthetic and the nervous system is very sensitive to it.

As a result, drinkers often lose modesty and self-control, as well as weakened or lost discernment, memory, concentration and comprehension. ◆3.Infection When people are infected with diseases such as pneumonia, typhoid fever, infectious hepatitis or tuberculosis, digestion and absorption are reduced, while consumption is greatly increased, and activity is reduced, often affecting brain function.

If you encounter external adverse mental factors at this time, it is easy to cause neurasthenia. ◆4.Trauma Brain dysfunction such as difficulty concentrating, headache, dizziness, memory loss, sleep disturbances, affective disorders, intellectual disability, and personality changes often occur after head trauma.

5.Poisoning Nowadays, there are signs of pollution everywhere in life, and if you don't pay attention to it, you will be poisoned, which will cause you to suffer from some strange diseases. The symptoms of neurasthenia are complex and changeable, and many patients compare their symptoms with themselves, blindly seek medical treatment, often misdiagnose and misdiagnose, and delay the best time to cause further deterioration of the condition.
