Quotes About Respiratory

Being an athlete in a cold-weather sport is really difficult to deal with the asthma.

Since the respiratory tract must allow outside air to pass into the innermost recesses of the body, it is extremely well defended. The lungs became the battleground between the invaders and the immune system. Nothing was left standing on that battleground.

In 2003 a new coronavirus that causes SARS, "severe acute respiratory syndrome," appeared in China and quickly spread around the world. Coronaviruses cause an estimated 15 to 30 percent of all colds and, like the influenza virus, infect epithelial cells. When the coronavirus that causes SARS does kill, it often kills through ARDS, although since the virus replicates much more slowly than influenza, death from ARDS can come several weeks after the first symptoms.)

But influenza is not simply a bad cold. It is a quite specific disease, with a distinct set of symptoms and epidemiological behavior. In humans the virus directly attacks only the respiratory system, and it becomes increasingly dangerous as it penetrates deeper into the lungs. Indirectly it affects many parts of the body, and even a mild infection can cause pain in muscles and joints, intense headache, and prostration.

Supplements don't appear to work. Studies have repeatedly shown that antioxidant supplements have no beneficial effects on respiratory or allergic diseases, underscoring the importance of eating whole foods rather than trying to take isolated components or extracts in pill form.

Influenza transmission is legendary. The dying cells in the respiratory tract trigger an inflammatory response, which triggers the cough reflex. The virus thus uses the body's own defenses to infect other potential hosts.

elderly, sedentary women have a 50 percent chance of getting an upper-respiratory illness during the fall season, those randomized to begin a half-hour-a-day walking program dropped their risk down to 20 percent. Among conditioned runners, though, the risk was just 8 percent.53 Exercising appeared to make their immune systems more than five times better at fighting infection. So what's going on here? How does the simple act of moving

against such respiratory-tract infections as pneumonia and influenza.55 Moderate exercise may be all it takes to boost IgA levels and significantly reduce the chance of coming down with flu-like symptoms. Compared to a sedentary control group, those who performed aerobic exercises for thirty minutes three times a week for twelve weeks had a 50 percent increase in the levels of IgA in their saliva and reported significantly fewer

While regular physical activity improves immune function and lowers respiratory infection risk, sustained and intense exertion may have the opposite effect. As you go from inactive to active, infection risk declines, but at a certain point, overtraining and excessive stress can increase the risk of infection by impairing immune function.57 In the weeks following marathons or ultramarathons, runners report a two- to sixfold increase in upper-respiratory-tract infections.

It was not until summer break that the next episode began. This time, it arrived in the form of a respiratory tic, a compulsive sniffing.

The action of the virus is unique. It begins by attacking the respiratory system, the lining of the lungs and the bronchial in particular. The victim develops a cough, which serves to propagate the virus. Then it spreads to the other internal organs and the brain. We know of no other viral epidemic where the pattern of symptoms match this one. It's a virus that we've never seen before.

An overdose could induce respiratory failure: you fall into a sleep so deep and blissful that you stop breathing. At small hospitals, patients were being admitted close to death. In trailers and dingy apartments and remote farmhouses, police and paramedics would arrive to a familiar scene—the OxyContin overdose—and set about trying to revive the user.

He did not want to have his newfound respiratory freedom ruined so soon be the sultry climate of humans.
