Ozone is a gas. It can be good or bad, depending on where it is. "Good" ozone occurs naturally about 10 to 30 miles above the Earth's surface. It shields us from the sun's ultraviolet rays. Part of the good ozone layer is gone. Man-made chemicals have destroyed it. Without enough good ozone, people may get too much ultraviolet radiation. This may increase the risk of skin cancer, cataracts, and immune system problems.
"Bad" ozone is at ground level. It forms when pollutants from cars, factories, and other sources react chemically with sunlight. It is the main ingredient in smog. It is usually worst in the summer. Breathing bad ozone can be harmful. It can cause coughing, throat irritation, worsening of asthma, bronchitis, and emphysema. It can lead to permanent lung damage, if you are regularly exposed to it.

What is pneumonia?
Pneumonia is an infection in one or both of the lungs. It causes the air sacs of the lungs to fill up with fluid or pus. It can range from mild to severe, depending on the type of germ causing the infection, your age, and your overall health.What causes pneumonia?
Bacterial, viral, and fungal infections can cause pneumonia.
Bacteria are the most common cause. Bacterial pneumonia can occur on its own. It can also develop after you've had certain viral infections such as a cold or the flu. Several different types of bacteria can cause pneumonia, including:
Viruses that infect the respiratory tract may cause pneumonia. Viral pneumonia is often mild and goes away on its own within a few weeks. But sometimes it is serious enough that you need to get treatment in a hospital. If you have viral pneumonia, you are at risk of also getting bacterial pneumonia. The different viruses that can cause pneumonia include:
Fungal pneumonia is more common in people who have chronic health problems or weakened immune systems. Some of the types include:
Anyone can get pneumonia, but certain factors can increase your risk:
The symptoms of pneumonia can range from mild to severe and include:
The symptoms can vary for different groups. Newborns and infants may not show any signs of the infection. Others may vomit and have a fever and cough. They might seem sick, with no energy, or be restless.
Older adults and people who have serious illnesses or weak immune systems may have fewer and milder symptoms. They may even have a lower than normal temperature. Older adults who have pneumonia sometimes have sudden changes in mental awareness.What other problems can pneumonia cause?
Sometimes pneumonia can cause serious complications such as:
Sometimes pneumonia can be hard to diagnose. This is because it can cause some of the same symptoms as a cold or the flu. It may take time for you to realize that you have a more serious condition.
Your health care provider may use many tools to make a diagnosis:
If you are in the hospital, have serious symptoms, are older, or have other health problems, you may also have more tests, such as:
Treatment for pneumonia depends on the type of pneumonia, which germ is causing it, and how severe it is:
You may need to be treated in a hospital if your symptoms are severe or if you are at risk for complications. While there, you may get additional treatments. For example, if your blood oxygen level is low, you may receive oxygen therapy.
It may take time to recover from pneumonia. Some people feel better within a week. For other people, it can take a month or more.Can pneumonia be prevented?
Vaccines can help prevent pneumonia caused by pneumococcal bacteria or the flu virus. Having good hygiene, not smoking, and having a healthy lifestyle may also help prevent pneumonia.

What is pulmonary rehabilitation?
Pulmonary rehabilitation, also known as pulmonary rehab or PR, is a program for people who have chronic (ongoing) breathing problems. It can help improve your ability to function and quality of life. PR does not replace your medical treatment. Instead, you use them together.
PR is often an outpatient program that you do in a hospital or clinic. Some people have PR in their homes. You work with a team of health care providers to find ways to lessen your symptoms, increase your ability to exercise, and make it easier to do your daily activities.Who needs pulmonary rehabilitation?
Your health care provider may recommend pulmonary rehabilitation (PR) if you have a chronic lung disease or another condition that makes it hard for you to breathe and limits your activities. For example, PR may help you if you:
PR works best if you start it before your disease is severe. However, even people who have advanced lung disease can benefit from PR.What does pulmonary rehabilitation include?
When you first start pulmonary rehabilitation (PR), your team of health care providers will want to learn more about your health. You will have lung function, exercise, and possibly blood tests. Your team will go over your medical history and current treatments. They may check on your mental health and ask about your diet. Then they will work together to create a plan that is right for you. It may include:

What are the health effects of smoking?
There's no way around it; smoking is bad for your health. It harms nearly every organ of the body, some that you would not expect. Cigarette smoking causes nearly one in five deaths in the United States. It can also cause many other cancers and health problems. These include:
Women who smoke while pregnant have a greater chance of certain pregnancy problems. Their babies are also at higher risk of dying of sudden infant death syndrome (SIDS).
Smoking also causes addiction to nicotine, a stimulant drug that is in tobacco. Nicotine addiction makes it much harder for people to quit smoking.What are the health risks of secondhand smoke?
Your smoke is also bad for other people - they breathe in your smoke secondhand and can get many of the same problems as smokers do. This includes heart disease and lung cancer. Children exposed to secondhand smoke have a higher risk of ear infections, colds, pneumonia, bronchitis, and more severe asthma. Mothers who breathe secondhand smoke while pregnant are more likely to have preterm labor and babies with low birth weight.Are other forms of tobacco also dangerous?
Besides cigarettes, there are several other forms of tobacco. Some people smoke tobacco in cigars and water pipes (hookahs). These forms of tobacco also contain harmful chemicals and nicotine. Some cigars contain as much tobacco as an entire pack of cigarettes.
E-cigarettes often look like cigarettes, but they work differently. They are battery-operated smoking devices. Using an e-cigarette is called vaping. Not much is known about the health risks of using them. We do know they contain nicotine, the same addictive substance in tobacco cigarettes. E-cigarettes also expose non-smokers to secondhand aerosols (rather than secondhand smoke), which contain harmful chemicals.
Smokeless tobacco, such as chewing tobacco and snuff, is also bad for your health. Smokeless tobacco can cause certain cancers, including oral cancer. It also increases your risk of getting heart disease, gum disease, and oral lesions.Why should I quit?
Remember, there is no safe level of tobacco use. Smoking even just one cigarette per day over a lifetime can cause smoking-related cancers and premature death. Quitting smoking can reduce your risk of health problems. The earlier you quit, the greater the benefit. Some immediate benefits of quitting include:
