Breathe better.

Breathing difficulties can have many causes, such as anxiety or strenuous activity. But it can also be a symptom of a serious problem, such as asthma, lung disease, emphysema, heart problems and pneumonia.

Asthma is a long-term condition that affects your breathing. It causes the airways that lead to the lungs to swell.

This is a condition where a person has an overwhelming urge to go to sleep.

Lung cancer occurs when abnormal cells grow out of control in the lung. Lung cancer can start anywhere in the lungs and spread to other parts of the body.

Sleep apnea is a disorder that causes a person to stop breathing for 10 seconds or longer during the sleep cycle. It can be mild to severe, based on the number of times an hour that you stop breathing or have slowed breathing

Snoring is a noise that you make while breathing during sleep. You snore when the flow of air from your mouth or nose to your lungs makes the tissues of your throat vibrate while you sleep. This is usually caused by blockage or narrowing in your nose, mouth or throat (airway).

Pulmonary fibrosis is a condition in which scarring occurs in the lungs. That scarring can be caused by an infection, such as tuberculosis or pneumonia, or injury or by breathing in certain materials, such as asbestos or from certain systemic disease like rheumatoid arthritis. But sometimes no cause can be found for PF. PF makes the lungs less elastic and can lead to breathing problems.

Chronic obstructive pulmonary disease (COPD)is a general term for a group of lung diseases, including emphysema and chronic bronchitis. People with COPD have deceased air flow in and out of the lungs, which makes it hard to breathe. The airways can get clogged with thick mucus. Cigarette smoking is a major cause of COPD.

Emphysema is damage to the air sacs in your lungs. In a healthy person, the tiny sacs in the lungs are like balloons. As you breathe in and out, they get bigger and smaller to move air through your lungs. With emphysema, these air sacs lose their elasticity, resulting in less oxygen getting into your blood and the feeling of a shortness of breath.

Pulmonary hypertension is high blood pressure in the arteries of your lungs. These blood vessels carry blood from the heart to the lungs where the blood picks up oxygen. The walls of the arteries may get thick and the arteries may get narrow. When this happens, blood does not flow as well as it should, pressure builds up in the arteries and causes your heart to work harder to pump blood through your lungs.
