They keep us alive and well and for the most part, we don't need to think about them. That's why it is important to prioritize your lung health. Your body has a natural defense system designed to protect the lungs, keeping dirt and germs at bay. But there are some important things you can do to reduce your risk of lung disease.
Here are some ways to keep your lungs healthy. Cigarette smoking is the major cause of lung cancer and chronic obstructive pulmonary disease COPD , which includes chronic bronchitis and emphysema. Cigarette smoke can narrow the air passages and make breathing more difficult. It causes chronic inflammation, or swelling in the lung, which can lead to chronic bronchitis. Over time cigarette smoke destroys lung tissue and may trigger changes that grow into cancer.
If you smoke, it's never too late to benefit from quitting. The American Lung Association can help whenever you are ready. Secondhand smoke, chemicals in the home and workplace, and radon all can cause or worsen lung disease. Make your home and car smokefree. Test your home for radon. Avoid exercising outdoors on bad air days. He is charming, friendly, talkative, quick to anger and quick to make a joke. At 74, he is once again confined to the lung full-time.
Only one other person in the US still uses one. The last person to use an iron lung in the UK died in December , at the age of No one expected someone who needed an iron lung to live this long.
And after surviving one deadly epidemic, Paul did not expect to find himself threatened by another. P oliomyelitis kills by suffocation — not by damaging the lungs, as Covid does, but by attacking motor neurons in the spinal cord, weakening or severing communication between the central nervous system and the muscles. The ensuing paralysis means that the muscles that make it possible to breathe no longer work.
Poliovirus enters the body through the mouth, via food or water, or unwashed hands, contaminated with infected faecal matter. Until the 19th century, almost all children would have come in contact with poliovirus before the age of one, while they still enjoyed protection from maternal antibodies transferred from mother to baby during pregnancy.
However, as sanitation improved, children were less likely to come into contact with poliovirus as babies; when they encountered it as older children, their immune systems were unprepared. In the US, from onwards, each summer brought an epidemic of polio in some part of the nation. At its peak in the 40s and 50s, the virus was responsible for more than 15, cases of paralysis in the US each year.
During this same period, it killed or paralysed at least , people annually worldwide. The year Paul contracted the virus, , saw the largest single outbreak of polio in US history: almost 58, cases across the nation.
Of those, more than 21, people — mostly children — were left with varying degrees of disability, and 3, died. Though polio was not the most lethal of epidemic diseases, it transformed everywhere it touched. In places where outbreaks occurred, families sheltered in fear at home with the windows shut.
All kinds of public gathering places closed. Human interactions were laced with uncertainty. According to the historian David Oshinsky, some people refused to talk on the phone out of concern that the virus could be transmitted down the line. Before the arrival of a vaccine in , what made polio so terrifying was that there was no way of predicting who would walk away from an infection with a headache, and who would never walk again.
In most cases, the disease had no discernible effect. As the virus hacked its way through the neural tissue of the spinal cord, a few of those infected were paralysed; this progression of the virus was known as paralytic polio.
If we had forgotten the terror of epidemics, we are now being forcibly reminded. The last time I spoke to Paul, in April, it was over Skype, from our respective lockdowns — him in his iron lung in an apartment in Dallas, with a rotating staff of full-time carers and an Amazon Echo next to his head, and me in my house in Surrey, England. Like polio, it has put normal life on hold. And just as with polio, we are pinning our hopes on a vaccine. There is even talk of bringing back the iron lung — a UK-based initiative is trying to bring a new negative-pressure ventilator called Exovent to hospitals for Covid patients.
This is Mr Shelter-in-Place. More than four months earlier, he had developed a persistent respiratory infection, which had sent him to hospital. He also suffers pain in his legs every time he is moved. His voice is slow, raspy and sometimes punctuated by gasps. His father crafted a stick like this when Paul was a child, and he has been using versions of it since. Though his body inside the lung is scarcely larger than it was when he was a child and his muscles atrophied, his neck measures 18 inches around and his jaw muscles bulge.
Its metal legs, ending in black rubber wheels, raise it to a height that suits a caregiver, while windows at the top allow them to see inside, and four portholes on the sides let them reach in. To open the machine, which weighs almost kg, carers must release the seals at the head and slide the user out on the interior bed.
The portholes, the pressure valves, the cylindrical shape and the colour all give the impression of a sturdy miniature submarine. Iron lungs were built to last, even if no one thought the people in them would. The device was invented in by Philip Drinker, a medical engineer, and Louis Shaw, a physiologist, at Harvard.
The iron lung was intended to be used for two weeks at most, to give the body a chance to recover. Over time, the claustrophobic iron lung became emblematic of the devastating effects of polio.
As Alexander aged, it became more difficult to breathe on his own. Lying on his back in the iron lung, he wrote using a pen attached to a plastic stick. A mirror above his head reflected his notes back to him. He self-published his memoir, Three Minutes for a Dog , in April. It took eight years to complete. One of the reasons Alexander wants to share his story is so people understand the severity of polio. After American virologist Jonas Salk developed a successful polio vaccine in , countries began spearheading immunization campaigns.
Since , no cases of polio have originated in the U. Children in the U. The calls to avoid gatherings of people. The fears. The anticipation of a cure. I find myself reading the pages of his memoir, in which he implores the world not to forget about the destructive consequences of polio, with a new sense of urgency. Click here to cancel reply. She knew then polio had come for her son. Air also enters through the MOUTH , especially for those who have a mouth-breathing habit, whose nasal passages may be temporarily blocked by a cold, or during heavy exercise.
These, in turn, split further into bronchioles. Each lobe is like a balloon filled with sponge-like tissue. Air moves in and out through one opening—a branch of the bronchial tube. The PLEURA are the two membranes, actually, one continuous one folded on itself, that surround each lobe of the lungs and separate your lungs from your chest wall. This motion carries MUCUS sticky phlegm or liquid upward and out into your throat, where it is either coughed up or swallowed. Mucus catches and holds much of the dust, germs, and other unwanted matter that has invaded your lungs.
You get rid of this matter when you cough, sneeze, clear your throat or swallow. While in the capillaries, blood gives off carbon dioxide through the capillary wall into the alveoli and takes up oxygen from air in the alveoli.
By moving downward, it creates suction in the chest, drawing in air and expanding the lungs. RIBS are bones that support and protect your chest cavity. They move slightly to help your lungs expand and contract.
