The lungs are very important organs as they are the ones that make it possible for the cells to obtain much-needed oxygen. Also, they are involved in having the body safeguarded against disease-causing microbes. Below are some tips on how to keep a person's lungs and entire respiratory system in tip-top shape, says a pulmonologist New York residents trust.

Quit smoking. Definitely, one of the most important steps that a smoker should take is turn his or her back on smoking. Tobacco smoke contains more than 7,000 toxic chemicals. Experts say that 70 of those are carcinogens or substances that can cause cancer. Needless to say, cigarette smoking is the number one risk factor for lung cancer.

Stay away from secondhand smoke. It's very much possible for an individual to end up with lung cancer even if he or she is not a smoker. Such is made possible by the inhalation of smoke given off by cigarettes or breathed out by smokers. This is what's known as passive smoking. Per year, passive smoking is the cause of around 3,400 lung cancer deaths in non-smokers in the US.

Reduce pollutant exposure. Pollutants in the air are just as bad for the health as cigarette smoke. That is why it is highly recommended for anyone to minimize his or her exposure to those. Sadly, pollutants can be found not only outside but also inside the home. In order to reduce indoor pollution, there are some steps that may be taken. Some examples include installing exhaust fans, removing carpets, vacuuming more often and getting rid of household products that have questionable ingredients in them.

Stay hydrated. Health authorities say that drinking about 2 liters of water per day is necessary for the proper functioning of the body's various organs, and they include the lungs. The consumption of plenty of water helps keep the mucus in the lungs and many other parts of the respiratory system thin. Mucus that's too thick can keep a person's respiratory system from carrying out its many different tasks properly.

Wash your hands with soap and water. It's important for you to regularly wash your hands or use alcohol-based hand sanitizer. This is a must especially when it's the flu or cold season. When in a public place, put on a surgical mask especially if there are lots of people around.

Exercise on a regular basis. In order to keep the lungs working optimally, the muscles involved in respiration such as the diaphragm the ones between the ribs should be strengthened. Such can be done with the help of cardiovascular exercises like brisk walking, jogging, swimming, bicycling, dancing and playing tennis. Taking slow, deep breaths most especially during stressful or anxious situations can help a lot, too.

Have well-balanced meals. The respiratory system is one of the body's various first lines of defense against disease-causing bacteria and viruses. It's for this reason exactly why keeping it in an excellent shape is of utmost importance. Opting for healthy eating helps ensure that the respiratory system is being supplied with all the nutrients it needs. The inclusion of foods rich in immune-boosting vitamin C to the diet is highly recommended.
