There are always some people who treat other people's lungs as their own ashtray. More than 70% of people are being forced to "take drugs"!
This is about Second-hand smoke . In recent years, people have become more and more "strikes" of second-hand smoke:
"The most hates people in the office smoking. There is always someone smoking by themselves. If you meet people, you will definitely be alone. While smoking, you will walk back and forth in the office..."

"My dad smokes, and I also smoked second-hand smoke for 22 years. I find that I often can't breathe and my brain reacts slowly than my peers. However, when my dad saw it, he said: Who made you stay up late?"
Second-hand smoke has become one of the problems that generally endanger national health, but it has not attracted enough attention. my country has even banned indoor smoking in recent years.
More than 70% of people: they are forced to "take drugs"
China is the country with the most smokers in the world. According to statistics, 316 million people have the hobby of smoking, and at the same time, they have also "made" 740 million passive smokers [1].
This means that more than 7 adults are inhaling second-hand smoke.
The harm of second-hand smoke to the human body is already a cliché. Its harm to the human body is no less than "drugs". In second-hand smoke, there are about 7,000 chemicals, hundreds of harmful substances, and at least 69 carcinogens.
If you think it is too abstract, let’s talk about something specific:
① Children continue to inhale second-hand smoke, and the harm will even continue until middle-aged
Children continue to inhale second-hand smoke, which may cause lung growth and degradation, resulting in the onset and worsening of Asthma , pneumonia and Bronchitis . The annual medical expenses range from 10,000 yuan. The pain you suffer is like boiling a frog in warm water. Some diseases cannot even be cured.

② Adults continue to inhale second-hand smoke, which is equivalent to 2h
adults continue to inhale second-hand smoke, which can cause serious cardiovascular and respiratory diseases. Women may have skin aging and hair loss due to it. annual medical expenses range from 20,000 to see a doctor, and even if they don’t smoke, they even suffer from lung cancer.
③Pets will also inhale second-hand smoke, shortening their lifespan by 3 to 7 years
Research from the University of Glasgow in the UK found that if the owner of a pet smokes, it will increase the risk of oral cancer, lymphoma cancer . Cats and dogs who smoke second-hand smoke are 3 times higher than cats and dogs without second-hand smoke, and some pets may even shorten their lifespans by 3 to 7 years.
WHO has long counted for us. In 2014, China's direct losses caused to us by treating tobacco-related diseases were about RMB 53 billion, accounting for about 1.5% of China's health expenditure of 3.5 trillion yuan in the same year.
As long as I am far enough away, will I not inhale second-hand smoke?
uh...it's hard to say.
Studies have calculated that the smoke produced by burning a cigarette contains many harmful substances, including pyrene as high as 180 ng. If smokes in a 30 cubic meter room, it will cause a concentration of 6 ng ng per square meter.
. According to the current hygiene standards, more than 1 nanogram per cubic meter is harmful. The pollution caused by a cigarette is 6 times that of the normal standard [3].
That is to say, second-hand smoke will cause harm in the space of at least 30 cubic meters.

However, once there is second-hand smoke in the room, only by changing the air 5 to 6 times can the air hygiene standards be reduced to the allowable range.
However, many air conditioners used in offices, hotels and homes do not have the function of filtering and removing such ultrafine particles.
So in these scenes, once the smoke from the cigarette is formed, it is very difficult to clear.
In an environment with poor ventilation conditions, as long as the second-hand smoke is exposed to a room full of smoke for 1 hour, the person who inhales it is about to smoke a cigarette [3]. Is the second-hand smoke produced by
Isn’t it harmful to me?
is not.
e-cigarettes produce not water vapor, but some second-hand aerosol . These gases are equivalent to "second-hand smoke", which also contains nicotine , and even carcinogens such as formaldehyde .
my country's governance and control of PM2.5 has gone through a long process, but e-cigarettes can easily be destroyed: The second-hand aerosol of e-cigarettes can cause the value of PM1.0 to be 14-40 times higher, and the value of PM2.5 to be 6-86 times higher.
At the same time, the content of certain metals (such as nickel and chromium) produced by second-hand aerosols of e-cigarettes is higher than that of traditional cigarettes. These substances look like hard "iron". Inhaled into our bodies, they may cause infertility, gastric ulcers, stomach cramps, and other problems.

So whether it is second-hand smoke produced by smoking or second-hand aerosol produced by using electronic cigarettes, it is harmful.
How can long-term exposure to second-hand smoke reduce the harm?
If you are forced to stay in a second-hand smoke environment for a long time, you can protect yourself through these aspects.
Please note ventilation
Even if the environment of second-hand smoke exists is troublesome, we cannot be careless. We can use these methods to speed up ventilation:
Summer fan: Place it at the source of second-hand smoke, blow it towards the window, and choose the maximum wind force.
More windows in winter: Choose one to two windows and open one third. At noon or in the morning when there are few people, open all doors and windows regularly for thorough ventilation.
Protective smoke-proof professional mask
Ordinary masks cannot filter second-hand smoke, including the blue medical masks we wear every day.
Second-hand smoke is an oily particle, so it is best to use masks with higher protection levels (the product standards can be seen on the packaging behind the mask). mainly uses masks with the product standards of GB/NIOSH type, which can prevent the odor of organic vapor and filter the oily particles.

If you are a family with pets, you can choose gerbera and drug-absorbing weed . It is harmless for pets to eat in small amounts.
Take a special experience
Below is a list of physical examinations for people who have been in a second-hand smoke environment for a long time:
Take others to quit smoking
Take people to quit smoking
Take people to quit smoking is the most fundamental method. The advice from family and friends around you will be more useful than strangers. In addition to verbal advice, you can also take some actions, such as posting some advice words on the cigarette box of smokers.
In addition, families with children or pregnant women should try to avoid contact with people who smoke as much as possible. Choose a smoke-free car when taking the bus, and choose a smoke-free room when staying in the hotel.
Of course, if you don’t smoke, there is nothing to do.
Data research shows that will significantly improve lung function after quitting smoking for 12 weeks. After quitting smoking for 1 year, the risk of coronary heart disease will reach half of the smokers, and after quitting smoking for 5 years, the risk of stroke will drop to normal.
Quit smoking, a simple and cheap way to get your health back, why not do it?
