Allergies and the Brain

A foal, just 9 hours old, at the Cal Poly Equine Center and another “newborn”

Spring time on the Central Coast starts…. NOW!

Thankfully, we’ve had some rain and the hills are green from San Luis Obispo to Sonoma. I traveled north this past weekend to assistant with wedding photography in Sonoma. During the car trip, I had fun taking in the ambiance of some northern sites, like the Golden Gate Bridge.  Also, I navigated with a map! (Imagine that!) An easy way to exercise your brain is to leave your GPS at home when traveling to new places.

Since I took a Cal Poly orienteering class I rarely struggle with getting lost, but the toughest part about going new places for me used to be my allergies.  There is nothing more embarrassing than wiping your nose constantly or sneezing your head off when trying to venture out.  It gets trickier when you run out of Kleenex and there is none near.  My friends who have known me since childhood will tell you that I’ve always had a tissue on hand.  In fourth grade, my teacher once jumped and threw his books in the air after I let out a LOUD sneeze due to the aroma of freshly cut grass sneaking in the open window.

I’ve had allergic symptoms to all the main culprits: dust, mold, pollen, grass, trees, pet dander, etc.

I never wanted my allergies to “win” so I hated taking allergy medicine.  When my husband finally forced me to go see an allergist, the doctor informed me I was a prime candidate for allergy shots because I was basically allergic to almost everything.  After the allergist’s assistant performed the arm and back prick test, I was just one red irritated mess.

Luckily, I had good insurance because that trip to the allergist would have been pretty expensive otherwise (don’t let that deter you from seeking help though!).  At that visit, the doctor informed me of a helpful online site where I could purchase special bedding and pillow case covers to deal with my dust mite allergy (gross!).

There were no dust mites out on the trails but that did not stop my runny nose and itchy eyes.  I continued to walk outside during the spring among the wild mustard in the open spaces in SLO County around Highwy 1.  I refused allergy shots, never went back to the allergist, and continued to sneeze A LOT (which really annoyed my husband).

Now, I don’t know why or how, but I seem to have kicked my extreme allergic symptoms.  Maybe it is because I quite walking in the open spaces during spring? Or maybe my sneezing fits stopped because I got rid of any carpet in my house or I am keeping my environment cleaner? Or that I moved closer to the ocean where there is a breeze that keeps the offenders away? Perhaps it is because I changed what I ate? I consume a lot more healthy fruits and vegetables than I did in the past.  Sadly, the only thing orange in my lunch used to be cheese puffs!

I don’t know exactly what to attribute it to, but I made positive changes and I am loving life without the daily attack of sneezes! I am not totally free of my allergy symptoms but I have noticed a big improvement.

Perhaps you can relate to having allergies? In a quick search for allergy statistics, I found that the American Academy of Asthma, Allergy, and Immunology website states that, “Allergies are among the most common chronic conditions worldwide.”  According to WebMD, allergies rank 5th among other leading chronic diseases in the U.S and one in 5 people in the U.S. have either allergy or asthma symptoms.  WebMD listed one estimate of the annual cost of allergies to the health care system and businesses in the U.S. at $7.9 billion.

There are many environmental factors that are causing today’s allergies. I just read, “The biodiversity hypothesis and allergic disease: world allergy organization position statement.”  (See end of post for the full citation and article link.)  Here’s how it starts off:

Abstract

Biodiversity loss and climate change secondary to human activities are now being associated with various adverse health effects. However, less attention is being paid to the effects of biodiversity loss on environmental and commensal (indigenous) microbiotas. Metagenomic and other studies of healthy and diseased individuals reveal that reduced biodiversity and alterations in the composition of the gut and skin microbiota are associated with various inflammatory conditions, including asthma, allergic and inflammatory bowel diseases (IBD), type1 diabetes, and obesity. Altered indigenous microbiota and the general microbial deprivation characterizing the lifestyle of urban people in affluent countries appear to be risk factors for immune dysregulation and impaired tolerance. The risk is further enhanced by physical inactivity and a western diet poor in fresh fruit and vegetables, which may act in synergy with dysbiosis of the gut flora. Studies of immigrants moving from non-affluent to affluent regions indicate that tolerance mechanisms can rapidly become impaired in microbe-poor environments.

I think if you take the tech talk out, the authors are trying to say there is less diversity in our good bacteria on our skin and stomachs, folks aren’t eating enough fresh fruits and vegetables, and aren’t exercising enough. When people move from a non-affluent area to a crowded city their immune systems suffer.  Hence, more allergies.  I was surprised at the mention of type 1 diabetes above. It is usually type 2 that would be mentioned along with obesity.

What also stood out to me from the article was the connection with nature and the natural environment and how it helps improves allergies.

An urban environment appears to lack elements that apparently are important for the proper development of immune tolerance. The recognition of the (absolute) dependence of humans on both the commensal and environmental microbiota is crucial to unravel the mechanisms involved. In recent years, concepts such as ‘ecotherapy’ [152], ‘green exercise’ [24] and ‘forest therapy’ [27] have been launched. Urbanization and densification policy continues globally, and within the next 30 years, it is estimated that two-thirds of the world’s population and 85% of the population in the developed countries will live in urban areas with little green space [153]. Prevalence of inflammatory diseases is likely to increase even more. The health effects of nature and green spaces (see ‘Biodiversity and human health’) should be recognized, and measures to limit excessive land use and fragmentation urgently undertaken.

As a biology enthusiast and graduate from California Polytechnic State University with a degree in Recreation Administration and a concentration in Natural Resource Management, the subject of forest therapy highly interests me.  It involves protecting natural resources, environmental medicine, and then you add in the brain component and you have all my favorite subjects tying together! (Nerd alert!)

A few years ago, I read the book, “Last Child in the Woods. Saving Our Children from Nature-Deficit Disorder,” by Richard Louv.  It seems that, “More time in nature– combined with less television and more stimulating play and educational settings– may go a long way toward reducing attention deficits in children, and, just as important, increasing their joy in life” (pg. 107).   Enjoying time outdoors may diversify a child’s microbes, help them focus better, and limit their need for Ritalin. Sounds like an inexpensive way to improve your child’s brain function, right? Time in nature might even boost their immune system and limit their need for allergy medication.

One of my favorite books to help with allergies, “Is This Your Child? Discovering and Treating  Unrecognized Allergies  in Children and Adults,” was written by Dr. Doris Rapp.  She states that: “Specialists in environmental medicine believe it is possible that any area of the body can be affected by an allergy or a food or chemical sensitivity” (Rapp, pg. 35).  This means your brain, even an infant’s brain, can be affected by allergies (Rapp, pg. 114).

Here’s some signs to look for in your child if you think their brain might be affected by an allergy: expressionless look  associated with red earlobes, wiggly legs, and dark eye circles (Rapp, pg. 67). Some adults may feel tired, depressed, and unable to think or remember things because of allergic brain fatigue. On the flip side, there are also hyperactive adults who are workaholic with brain allergies. (Rapp, pg. 153).

It has been noted that the brain can be affected by a wide range of common allergic stubstances.  Observation dating back to the mid-1930s indicated that odors, foods, pollen, molds, and dust could cause a wide range or problems in the nervous system. Entire chapters in texts for physicians written between the thirties and fifties were devoted to the role of allergy in relation to headaches, fatigue, epilepsy, behavior problems, minimal brain dysfunction, psychological  problems, and a wide range of other neurological or learning problems in children. (Rapp, pg. 394).

It seems this valuable information mentioned above was not included in past or present medical training for physicians specializing in allergy or neurology (Rapp, pg. 394). I truly hope things have changed and brain allergies are more widely studied.  If this subject interests you, you can read more about it in Dr. Rapp’s book listed in the sources below.

Take some time to let your brain find joy outdoors and do your part to protect the environment!  Future generations seeking allergy relief may depend on it!

Two Products My Brain Would Agree to Give Awards To

DishwasherTwo weeks ago, Parade, published their winners for “The Product of the Year Awards!”

Here’s the two products that I would give a thumbs-up to from their 23 picks (note: I am not “sponsored” by any companies):

1.  Le Savonnier ­Marseillais All-Purpose Soap

First, let me state that I’ve never used this soap. I’m basing my opinion solely on what I’ve read about the soap and checked out online.  This soap does not contain dyes and seems to contain a minimal amount of “safer” preservatives. I give it a thumbs-up since they offer a fragrance free option and say, “Way to go, Le Savonnier Marseillais!”

Their all-purpose soap sounds great and has really pretty packaging, but for now I will be sticking with my go-to-soap, Dr. Brooner’s Magic Soap, specifically the Baby-Mild Liquid Unscented Soap (certified fair-trade and organic).  I steer clear of products with fragrances since my household is allergic to most chemical and natural fragrances.  This soap is great for sensitive skin.  I mix it with water in a foaming hand soap dispenser to make it last longer.  This is a big plus since I have children who can be a bit overzealous when pumping soap.

2. Finish Quantum Power & Free

I must admit I use Finish products- A LOT! I use my dishwasher at least 7 times a week.  When I bought my dishwasher five years ago, I consulted Consumer Reports on which dishwasher to purchase and what dish washing detergent worked best.  I believe they recommended Finish Powerball tabs.  I was delighted with the clean dishes and even happier when I found out Costco sold the tabs in bulk.  Once my husband bought another brand on sale at Costco and it was a lemon-flavored dish-coated disaster after the first load.  He quickly returned the lemon goo and went back to Finish Powerball formula.

The Finish’s product that was picked for Parade’s list, Quantum Power and Free, contains no chlorine bleach and fewer fragrances and dyes. I wish there were no fragrances and dyes instead of fewer! (Anyone have a recommendation for one that doesn’t have these ingredients but actually works?)  Finish is giving away free samples, so I’m going to give them a try and see if I notice a difference in my dishes.

Until I find the perfect tabs, or get rid of my dishwasher (because of the scary amount of tabs I’ve used in the last five years!), I give a thumbs-up to the product engineers at Finish for trying to improve!

Do dyes in soaps help them clean better?

What about the other 21 products listed in Parade?

I’m going to keep this post positive so I won’t voice my thoughts on the other 21 products.

Check them out for yourself and let me know which product selections  you agree with!  Do you see any patterns from the list in terms of what Americans’ brains prefer? (hum.. convenience food? candy? soda? video games?)

What are the best products for your brain?

I believe the best products for your brain are the ones that are free of dyes and other types of chemicals/preservatives.  I’ve mentioned super brain foods and super brain drinks on my blog, but sometimes the “best-for-your-brain product” is the actual product of your actions.  This is the case when it comes to the benefits associated with exercise and socializing.  It doesn’t cost any money to take off your shoes and go for a walk on the beach or play a board game with your grandchildren.  Don’t be swayed by flashy marketers pushing their best brain supplements.  Do your research, stay active, eat in moderation, get enough sleep, consume healthy fruits and vegetables, try new things, and keep social connections.  Also, make sure to keep your environment clean and as chemical free as possible.

It may seem overwhelming if you are not doing these things I’ve mentioned, but focus on just one area of your life to improve at a time.  You may not win any awards, but if you continue to pay attention to what’s best for your brain you won’t regret it!

I give you a thumbs-up for trying!

A Brainy Invertebrate with a lot of Heart

Morro Bay Harbor

This year I’ve had more contact with cephalopods than usual.  While this sounds like something that belongs in a movie, (perhaps, Close Encounters of the Third Kind?), the type of alien-ish cephalopod I am referring to is an octopus.  They live in the depths of the ocean, not in deep space.

The first octopus I discovered was washed up on the shore in Morro Bay Harbor in January.  I’ve never found an octopus on the shore before (or in the water).  Something was wrong with it, although it seemed to have a pulse.  A sympathetic surfer, my husband, gave it a ride farther out to sea.  Hopefully, the little one made it.

Octopus

Then, about a week ago, I had my second encounter with an octopus– a giant red one.  He was behind glass at the Monterey Bay Aquarium.  After watching a video presentation, I was struck by how smart and “affectionate” giant Pacific octopuses are.  (Maybe they are so affectionate because they have three hearts?)  A giant Pacific octopus at the Monterey Bay Aquarium was able to differentiate between the aquarists and give “hugs” to his favorite aquarist.

Giant Pacific Octopus at Monterey Bay Aquarium

It is thought that a giant Pacific octopus exhibits a red color to show emotion. I wonder what this one was communicating to the two boys in the red shirts?

I listened to a podcast online and the interviewee from the Monterey Bay Aquarium thought giant Pacific octopuses were as smart, or smarter, than a house cat.  However, I don’t think we will be watching any YouTube videos of octopuses doing “cute” things.  Since they are masters of disguise, you will probably be seeing more videos like the one of an octopus’ stealth moves to enter into a game of tug of war over a diver’s camera.  Maybe the octopus was trying to taste it since they can taste/smell through their suction cups?

An octopus has the biggest brain of all cephalopods.  It has 500 million neurons (we have 100 billion).  Their nuerons are not in once place, like ours, and some neurons run along its eight arms, or tentacles.  These arms can unscrew jars, even childproof bottles, to get food out.  Not many marine animals use “tools” like an octopus can.  I guess it helps having so many arms.

What can we learn from an octopus?  Probably a lot. I watched a video,  Octopus Brains, that was part of a presentation at University of New Mexico’s annual conference on Integrating Nanotechnology with Cell Biology and Nueroscience.  Some researchers are trying to design self-maneuvering robots that are based on octopus’ neurophysiology and behavior.   It would be easier to model the robot’s CPU after an octopus brain rather than a human brain, because human brains are much more complex.   Although, recently, I discovered we may not be far off, when I read an article by Traci Pedersen on PyschCentral.com about Spaun, the world’s largest simulated brain.

Researchers are hoping that the world’s largest simulated brain — known as Spaun — will be used to test new drugs that lead to breakthrough treatments for neurological disorders such as Parkinson’s, Huntington’s, and Alzheimer’s disease.

There is some pretty amazing stuff going on in brain research. What about you?  Have you had any cephalopod encounters lately?

What are you doing for your brain health in terms of “new learning”?
