Allergy Season Explained

teded:




Happy First Day of Spring, Tumblr! 


What better way to celebrate than to **ACHOO!!**….wait, what were we saying?


image

Ah, spring! Grass growing, flowers blooming, trees growing new leaves, but if you get allergies, this explosion of new life probably inspires more dread than joy.  


image

Step outside, and within minutes, you’re sneezing and congested. Your nose is running, your eyes are swollen and watery, your throat is itchy. For you and millions of others, it’s seasonal allergy time. So what’s behind this onslaught of mucus?


image

The answer lies within you. It’s your immune system. Seasonal allergies, also called hay fever, or allergic rhinitis, are a hypersensitive immune response to something that’s not actually harmful. Pollen from trees and grass, and mold spores from tiny fungi find their way into your mucous membranes and your body attacks these innocuous travelers the same way it would infectious bacteria. 


image

The immune system has a memory. When a foreign substance gets tagged as threatening, white blood cells produce customized antibodies that will recognize the offender the next time around. They then promptly recruit the body’s defense team. But sometimes, the immune system accidentally discriminates against harmless substances, like pollen. When it wafts in again, antibodies on the surface of white blood cells recognize it and latch on.


image

This triggers the cell to release inflammatory chemicals, like histamine, which stimulate nerve cells, and cause blood vessels in the mucous membranes to swell and leak fluid. In other words, itchiness, sneezing, congestion, and a runny nose. 


image

Allergies usually, but not always, show up for the first time during childhood. But why do some people get allergies and others don’t? Allergies tend to run in families, so genetics may be one culprit. In fact, errors in a gene that helps regulate the immune system are associated with higher rates of allergies. The environment you grow up in matters, too. Being exposed to an allergen as a baby makes you less likely to actually develop an allergy to it. People who grow up on farms, in big families, and in the developing world also tend to have fewer allergies, although there are plenty of exceptions, partly thanks to genetics. One theory is that as children, they encounter more of the microbes and parasites that co-evolved with traditional hunter-gatherer societies.


image

Called the hygiene hypothesis, the idea is that when the immune system isn’t exposed to the familiar cast of microbes, it’ll keep itself busy mounting defenses against harmless substances, like pollen. Another theory is that an immune system toughened up by a barrage of pathogens is less likely to overreact to allergens. Pollen is a common offender, just because we encounter so much of it, but there’s a long list of substances: dust, animal dander, insect venom, medications, certain foods, that can send your immune system into overdrive. Some of these reactions can be scary. An allergy can develop into full-blown anaphylaxis, which typically brings on severe swelling, shortness of breath, and very low blood pressure. It can be deadly.


image

But as we who suffer from seasonal allergies know, even non-life threatening allergy symptoms can make you miserable. So what can you do about it? Medications can help reduce the symptoms. The most common ones keep histamines from binding to your cells. These antihistamines stop the inflammation response. Steroids can help dial down the immune system. Another more permanent option is immunotherapy. Deliberate, controlled exposure to gradually increasing amounts of an allergen can teach the immune system that it isn’t dangerous after all. 


image

Of course, you can always just wait your seasonal allergies out. The spring pollen onslaught dwindles by mid-summer…just in time for ragweed season!

Teaching Children About Inclusion

One of the most important lessons you will ever teach your child is about inclusion. It’s crucial that your child learns about tolerance and diversity in the world. They need to understand that others may be different than them, but they are just as special.

If your child says they don’t want to invite a certain friend to their party because they may act weird, dig for the real concern. You can explain to your child that just because a person may act differently doesn’t mean they are “weird.” You can remind your child that they don’t need to focus on one person at the party. It’s important that they pay attention to everyone equally at the party. They should quickly learn that including everyone will make each person feel special.

Children should grow up to be inclusive from a young age. They shouldn’t have to learn this value later in life. They should learn that everyone is unique.

Always encourage your child to include other people with disabilities. Even if the child cannot play the same as your child, it’s important to engage with them. They can make up games or change their type of play to include everyone., to play.

Teach your child to always treat others the way they want to be treated. It’s a traditional saying, but it rings true just as much today as a thousand years ago. Tell them to try to step into the other person’s shoes. Treat that person with respect and dignity, the way they would want to be treated.

Never label a child that has special needs. Tell your child to never say “the kid that has hearing aids” or “the one that is in a wheelchair.” This only points out differences. It’s important to see past these disabilities to the person’s core. Even if they don’t notice the difference, it’s important they learn not to label them, even if it is on accident.

Tell your child how special they are as a person. They should understand that if a child with special needs is belittling them, they don’t get special treatment just because they have a disability. Everyone is on an equal playing field and should be treated special.
