Q: Asthma tends to start during childhood, though it can affect both men and women of all ages. Adult women tend to be at higher risk than adult men. During childhood, however, more boys than girls have asthma. Other factors play a role in asthma as well. Along with environmental factors, there are genetic factors. If someone in the family has asthma or atopy (extreme allergies), the risk for asthma is increased. In asthma, the breathing airways (bronchi, bronchioles) are inflamed. This pattern of inflammation causes the airways to swell and to be sensitive to a number of inhaled substances that act as triggers for an asthma attack.  During an asthma attack, the airways become even more swollen and narrowed, making it very difficult to breath. Also, part of the inflammatory response in the lungs includes the production of mucus. During an asthma attack, even more mucus is produced, increasing the difficulty of getting a full breath and getting enough oxygen. There are 2 main types of asthma: intrinsic (non-allergic) and extrinsic (allergic) asthma. Extrinsic asthma is more common, directly involves an immune response, and is triggered by inhaled substances.  Intrinsic asthma is triggered by cold air, exercise, dry air, and stress. The immune response is somewhat less critical in intrinsic asthma, but both involve an inflammatory response. Both forms of asthma can be mild, moderate or severe and both can be intermittent. Diagnosis is usually by a history of symptoms and family history—you need to have a diagnosis from your physician. The most common symptoms of asthma are: coughing (often worse at night or early in the morning), wheezing (a whistling or squeaking sound that occurs during a breath), tightness in the chest, and shortness of breath. These symptoms can be triggered by a number of different substances or events. It is not altogether clear what causes asthma. However, there is some solid evidence that the lack of exposure to bacteria, viruses, fungi, molds, and other pathogens early in life is at the root cause of asthma. This is called the “Hygiene Hypothesis.”  The immune system discriminates between “self” and “non-self.” Part of the way the immune system learns to do this is by being exposed, from birth, to a variety of pathogens, such as bacteria, fungi and viruses. Because modern society puts so much emphasis on sanitation and cleanliness, we spend a good deal of time sterilizing our environment. As a result, it is proposed that our immune systems do not learn those essential early lessons and tends to over-react in some cases (autoimmune diseases, atopy, allergies) and under-react in other cases (increased number of infections).  One bit of evidence that supports this hypothesis is that children who are raised on farms and around animals tend to have lower rates of both asthma and allergies (atopy).
A: Assess whether you are at high or low risk of having asthma. Understand what asthma is. Understand the different types of asthma. Look for symptoms of asthma. Research theories about the causes of asthma.

Article: Bathroom policies will vary from school to school, teacher to teacher, and grade to grade. If you do not understand the bathroom policy, ask your teacher or professor to explain the rules and procedures to you. If you can not remember the restroom rules, ask your teacher to remind you of the rules. If you can not comply with any part of the bathroom policy, set up a meeting with your parents, teacher, and principal to discuss the concern and develop a solution you can all agree on.  In elementary, middle, and high school, you may be required to ask for permission to use the restroom. In college and graduate school, most professors will let your come and go from the classroom as you please. When you do get up to use restroom, leave and re-enter the room quietly and discretely. If you are an exchange student, ask your host family, roommate, teacher, or professor to explain the country's cultural norms regarding using the bathroom at school. Before asking to use the bathroom, make sure it is a convenient time for you to ask this question. Ask yourself, “Is it a good time to talk to my teacher and leave the classroom?”  Avoid asking your teacher to use the bathroom when they are in the middle of giving instructions, during the middle of a lecture, or during a lesson. Do ask your teacher to use the restroom during independent work times, when you have finished all of your class work, or after you have completed a test. If it is an emergency, remain calm and ask your teacher immediately. When it comes to asking to use the restroom, each teacher has a different policy. While some teachers prefer the traditional method of raising your hand to ask for permission, other teachers find this practice disrupting. Instead, they insist that their students use a special hand signal.  Raise your hand, wait patiently to be called on, and ask for permission to use the restroom. “May I please go to the restroom, Mr./Mrs/Ms. ____.” Raise your hand with the special signal (perhaps crossed fingers) and patiently wait for a response. If your teacher is fine with you using the bathroom, they may nod their head "yes.” If your teacher would like you to wait, they may shake their head “no” or raise a finger to signal “wait a few minutes, please.” Your teacher may respond in one of three ways: “yes,” “no,” or “not right now.” If you don’t receive the answer you were hoping to hear, you must respect your teacher’s answer. If it is an emergency, tell your teacher it is an emergency and you can't wait to use the restroom.  If your teacher says “yes,” thank them and exit the room. After using the bathroom, return to the room quietly. If your teacher says “no” or “in a minute,” ask again in a little while.
