What are the hazards of inhaling secondhand smoke

In today's society, perhaps due to work pressure or family troubles, more and more people are smoking, and many women are also slowly starting to smoke. Of course there are people who smoke and there are also people who advocate smoking cessation. Many non-smokers are also harmed by smoking because smokers produce some substances when they smoke, and these substances can pose a threat to human health. These substances can be called secondhand smoke. Moreover, the harm of secondhand smoke to the human body is actually no less than that of direct smoking. Now let’s talk about the dangers of inhaling secondhand smoke.

While smoking harms the health of smokers themselves, secondhand smoke also affects non-smokers. In addition to irritating the eyes, nose and throat, it will also significantly increase the chances of non-smokers developing lung cancer and heart disease, as well as other respiratory diseases, seriously harming people's health.

If you spend more than 15 minutes with a smoker every day, the harm to you from second-hand smoke is the same as that to smokers themselves. 75% of lung cancer patients can be traced back to smoking. Everyone has "proto-oncogenes" that enable people to grow during the embryonic period, but they should stop working at the appropriate time, otherwise people are prone to cancer. Smoking can cause this gene to start working again and cause cancer. If a non-smoker lives or works with a smoker and smells cigarette smoke for a quarter of an hour every day for more than a year, the harm is equivalent to smoking.

As the name suggests, secondhand smoke is an indirect form of smoking. Direct smoking can cause harm to the human body, but the harm caused by indirect smoking is no less than direct smoking. There are actually many dangers of inhaling secondhand smoke. Although many people do not want to smoke, they may inhale secondhand smoke and endanger their health because there are people smoking around them. So, from now on, advocate no smoking and stop smoking.
