    How Traffic Affects Our Health

    When talking about traffic problems, we also need to take into consideration the pollution that we are exposed to and the health problems traffic causes. Given below is an in­depth exposition on how traffic affects our health and what we can do to avoid some of these effects to live a longer and healthier life.

    Achesand Pains

    Driving in a slouched(无精打采的) position puts pressure on your back and neck. Back pain is often due to poor posture which can have a negative effect on your health. Your bad posture also puts stress on the joints of your elbows and knees, causing pain and tiredness to these areas of your body.

    When you are driving in traffic, you are constantly shifting between the accelerator and brake (in automatic transmission cars), and clutch, brake, and accelerator (in manual transmission cars). This constant shifting puts pressure and stress on your knees, causing knee­related problems and aches.

    What can you do?

    You can counteract these ill effects and posture problems by sitting upright and having a support for your lower back and neck. Adjust the position of your seat in such a way that you can drive at ease without any discomfort. The backrest of the seat should be straight up, and not pulled down too much.

    Respiratory(呼吸的) Problems

    Exposure to heavy traffic implies exposure to poisonous gases that are emitted by vehicles. It is believed that the transportation sector in the US is responsible for a quarter of the country's greenhouse gas emissions.

    Our lungs are like sponges, soaking in everything that is breathed in by our respiratory system. The smoke coming out of the tailpipes of vehicles presents a serious threat to human health. Prolonged exposure to traffic emissions can cause various respiratory diseases including lung cancer.

    What can you do?

    There are ways to avoid breathing in polluted air. If you can, avoid driving in parts of your town with heavy traffic congestion. However, if you find yourself driving through such areas, roll up your car windows to minimize exposure to harmful gases. If you plan to go out for a walk or run, do it in a place where you get loads of fresh air. Eat foods that are rich in antioxidants(抗氧化剂), and exercise regularly so that your immune system is strong enough to fight off potential threats to your health.

    Travel and traffic are two things that are absolutely unavoidable, and that is why we should try to be as comfortable as possible, to be stress­free and illness­free!
