To prevent lung cancer in winter, you should stay away from the hazards of secondhand smoke

Winter is the peak season for respiratory diseases and also the season with a higher risk of lung cancer. There are many reasons for this situation, one of the main reasons is secondhand smoke pollution.

Why do I say this? Secondhand smoke can be encountered almost everywhere, whether in public places or at home. As long as someone actively smokes, there will be someone who is passively exposed to smoke for no reason. In fact, the harm of secondhand smoke to the human body is no less than smoking, and studies have shown that secondhand smoke is an important factor in causing lung cancer.

According to research, the smoke from burning cigarettes contains more than 4,000 harmful substances, many of which are carcinogenic. In addition to nicotine, a recognized carcinogen, the smoke also contains a large amount of radioactive elements. These elements are absorbed by the human body and continuously accumulate, releasing alpha rays, damaging the body's cells and creating an environment for the growth of cancer cells.

So why does the harm of secondhand smoke to the human body increase in winter? This is because the weather is extremely cold in winter, and people generally seldom go out and stay in closed houses or other environments for a long time. Many unconscious smokers smoke without regard for the health of others. The smoke will be trapped in the house and cannot dissipate. It will be inhaled into the lungs, increasing the risk of lung cancer.

Even outdoors, there is more haze in winter, and car exhaust fills the air and cannot dissipate in time, especially in traffic jams. The exhaust concentration in local areas will be higher, and high-concentration car exhaust can also cause damage to the lungs and increase the risk of lung cancer.

Therefore, people should strengthen respiratory protection in winter, reduce the harm of secondhand smoke, and pay attention to indoor ventilation to stay away from the risk of lung cancer.
