Secondhand smoke is a known cause of numerous illnesses and is particularly hazardous to people working in the service industry. It can also affect pregnant women, infants, and unborn children. Pregnant women may experience low birth weight and low fetal heart rates due to lower oxygen levels, which may lead to miscarriage, stillbirth, or premature delivery. Infants, meanwhile, cannot always get out of a smoke-filled room, which increases the dangers of exposure.

Secondhand Smoke Cancer

Secondhand smoke is a huge health risk for people who become exposed. People who live with a smoker, who drive with a smoker, and those who work in an environment where there are smokers are all at risk of developing health problems. Secondhand smoke can damage cells in the body and can even set off the cancer process. Fortunately, most people can avoid this threat by staying in a smoke-free environment.

Secondhand smoke can also damage the lungs, causing frequent breathing problems and worse asthma attacks. It can also damage eyes and teeth, and can increase the risk of heart disease.

Heart disease

The American Heart Association recently published a scientific statement about the health risks associated with secondhand smoke exposure in children. The statement addresses the prevailing evidence, the burden of evidence, and racial and socioeconomic disparities. It also points to the potential harm of secondhand smoke on children’s development.

The authors of the report found that secondhand smoke exposure is associated with an increased risk of cardiovascular disease and stroke. This association was also seen in two other studies that examined the relationship between secondhand smoke and other risk factors.

Nasopharyngeal cancer

Nasopharyngeal cancer is a cancer of the back of the throat. It can be diagnosed by the presence of a lump on the back of the neck, which is typically not painful. This lump forms when the cancer has spread to lymph nodes in the neck. Because the symptoms of nasopharyngeal cancer are similar to those of other diseases, it can be difficult to detect it at the early stages.

Nasopharyngeal cancer is generally curable if diagnosed in an early stage. Treatment usually includes chemotherapy and radiotherapy. In some cases, surgery is used. The survival rates for people diagnosed with this type of cancer are not very high in the UK. Nevertheless, most people will live for at least a year and 50% will live five years or longer.

Asthma

Secondhand smoke has been linked to many health problems, including lung cancer, heart disease, stroke, and asthma. Exposure can even lead to early death in children. Children with asthma are particularly susceptible to secondhand smoke because it worsens the symptoms of the disease. Asthma is a breathing condition that affects the airways, which can lead to chest tightness, coughing, and wheezing.

Smoking can also exacerbate the effects of asthma medicines. In children, smoking makes flare-ups more likely, which can cause them to miss school or other activities. Smoking also prevents them from getting enough rest and may lead to problems sleeping. Adults with asthma may also suffer from secondhand smoking symptoms, including wheezing and coughing. Secondhand smoke can also lead to an uncontrollable asthma attack in adults.

Lung inflammation

Secondhand smoke may induce inflammation of the lungs, as a result of the irritant effect on pulmonary tissue. Although the exact mechanisms of this effect are not known, the evidence suggests that secondhand smoke may induce chronic inflammation in the lungs. In Vitro studies have indicated that secondhand smoke can inhibit the growth of endothelial cells in small blood vessels of the lungs. These cells line the inner walls of blood vessels and control the transport of white blood cells into the bloodstream. The decreased number of endothelial cells renders blood vessel walls less elastic and prone to chronic inflammation.

In addition to causing inflammation in the lungs, secondhand smoke can also cause a number of other problems. These include more frequent and severe asthma attacks, and damage to the eyes and teeth. It can also increase the risk of heart attacks and clots. In some cases, secondhand smoke can lead to lung cancer.

Vitamin depletion

Studies have shown that children exposed to secondhand smoke are more likely to have low vitamin D levels than children who are not exposed to smoke. According to a study published in the PLOS One journal, 21 percent of children who were exposed to secondhand smoke were deficient in vitamin D compared to 15 percent of children who were not exposed. Additionally, 18 percent of children who were exposed to active smoking were deficient. The researchers determined that both smoking and exposure to secondhand smoke significantly predicted vitamin D deficiency. The researchers also found that race, body mass index, maternal education, and family socio-economic status were associated with vitamin D deficiency.

Smokers have a decreased intake of vitamin C, an important antioxidant. A survey conducted in 1989 found that smokers had the lowest intake of vitamin C, with those who smoke 20 or more cigarettes per day having slightly higher circulating levels. Moreover, smoking adversely affected smokers’ preference for vitamin C rich foods. It is possible that oxidative stress and reduced levels of vitamin C in the body may be related to heart disease.

Increased risk of heart attack

The risk of heart attack from secondhand smoke is increased in two main ways. First, it affects the heart’s arteries, making it susceptible to thrombosis and CHD. Second, it can lead to increased blood pressure, which in turn can lead to heart attacks. While these two effects are separate, they are related.

Studies also point to the association between secondhand smoke and CHD mortality and symptoms. These findings are based on data from case-control studies and cohort studies. These data show that secondhand smoke exposure contributes to a substantial burden of preventable deaths. In addition, workplace exposure is the most prevalent setting for exposure to secondhand smoke, and pooled RRs indicate that it is a significant occupational hazard.
