INTRODUCTION
The difference between good health and disease is that health is the level of functional or metabolic efficiency of a living being. In humans, it is the general condition of a person's mind, body and spirit, usually meaning to be free from illness, injury or pain (as in “good health” or “healthy”) whiles a disease is an abnormal condition affecting the body of an organism. It is often construed to be a medical condition associated with specific symptoms and signs that may be caused by external factors such as infectious disease, or by internal dysfunctions, such as autoimmune diseases. The differences between signs and symptoms are signs are what a doctor sees, they are the physical manifestation of injury, illness or disease and shows a definite indication of a specific disease, whereas symptoms are what a patient experiences and can be defined as one of the characters of a disease, it can also be described as what a patient experiences about the injury, illness or disease. A doctor may notice in a patient a high temperature, rapid pulse, low blood pressure, open wound or bruising which are all signs of a disease. Whiles a patient notices symptoms of a disease for instance chills, shivering, fever, nausea, shaking and vertigo which are all symptoms.
ASTHMA
Asthma is a disorder that causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest tightness, and coughing. Asthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can pass by.
Common causes of asthma attacks are:
• Animals (pet hair or dander)
• Dust
