Acute bronchitis, commonly known as a chest cold, is a viral or bacterial infection in the bronchial tubes that affects your ability to breathe normally, according to the U.S. Centers for Disease Control and Prevention. A chest cold can last up to two weeks.

Asthma is the result of inflammation and constriction of the bronchial tubes. Allergens, environmental irritants and even stress can cause symptoms of asthma. If untreated, asthma can start with mild symptoms such as a cough or wheezing, and then escalate into an asthma attack.

The lungs are a pair of organs in the chest responsible for respiration, a process that involves breathing in air and adding fresh oxygen to the blood, which then carries the oxygen to the cells. Many factors and conditions can alter how the lungs function, such as lung cancer and respiratory infections.

Muscle aches, fatigue and shortness of breath are three symptoms that often present themselves concurrently and are common to a variety of disorders or illnesses.

Four-square breathing, sometimes referred to as the box breathing technique, is a simple technique that you can do at any time that you feel stressed.

Many people have allergies to airborne dust, mold, and pollen. These tiny particles can accumulate in your home environment, potentially leading to health problems.

There’s a popular saying in the Philippines that goes, “A coconut a day keeps the urologist away.” It sounds quirky, but there seems to be some truth to it.

Bronchial pneumonia, also called bronchopneumonia, infects the bronchioles, the tubes leading to the lungs and the lungs themselves. Bronchial pneumonia affects millions of Americans each year, particularly the elderly and immunocompromised. Many different bacteria, viruses or fungi can cause bronchial pneumonia.

As a chronic lung disease, asthma is commonly treated with inhaled medications delivered to the airways with either a handheld inhaler or a nebulizer. A nebulizer machine changes liquid medication into a mist inhaled through a mouthpiece or mask.

Poor air quality is a problem all over the world. Polluted air is linked to a variety of health concerns, ranging from short-term irritation to serious diseases or even death. Much of the pollution that's affecting our air comes from human activities.
