Why Dirt Is Good: 5 Ways to Make Germs Your Friends [Hardcover]

Mary Ruebush (Author)

Book Description

Release date: January 6, 2009

"The archetypal link between dirt and guilt, and cleanliness and innocence is built into our language," says journalist Katherine Ashenburg. But Dr. Mary Ruebush counters that with the fact that Western civilization's obsession with antibacterial soaps and our quest to be clean all the time is actually making us sick.

Why Dirt is Good is a fun look at the plus side of dirt and germs. Complete with cartoons, the book features irreverant yet medically sound advice that illustrates how we can become healthier by exposing ourselves to a bit of dirt and germs. Divided into four parts, the book will explore through text and cartoons:

Part 1

• Dirt = good, antibiotics = bad

Part 2

• How your immune system really works
• How the immune system develops in children

Part 3

• What a germ or bug is trying to do to prolong its life in the presence of antibacterials and antibiotics

Part 4

• What you can do to make your immune system healthier

Editorial Reviews

From Publishers Weekly

In her first book, microbiology and immunology teacher Ruebush demonstrates a lively mastery of her subject, providing a better education in immunology than a convincing case for the idea that "the most delightful sights for a parent should be a young child covered in dirt from an active afternoon of outdoor play." Her thesis, reiterated throughout, is that obsessive cleanliness is counterproductive: a "young, naïve immune system" needs exposure to germs "to build the ability to produce the right response quickly." Arguing that evolution has conditioned us to coexist with the microscopic threats around us-a human body typically harbors "some 90 trillion microbes"-Ruebush considers the legacy of "superbugs" bred through the overuse of antibiotics and cleaning products, and dismisses vaccination fears as ridiculous ("not even a question"). Ruebush presents a step-by-step guide to the workings of the immune system that should inform readers new to the subject, but her breezy and repetitive approach to arguing her thesis probably won't win over any doubters.

4.0 out of 5 stars Short, sweet and convincing March 2, 2009

By Kristine Lofgren VINE™ VOICE

Format:Hardcover

In this book, Mary Ruebush makes the case that we need to get a little "dirtier" if we want to improve our health and the health of generations to come.

Laid out in 5 different sections, this book explains how we have created "super-germs" and have actually lowered our immune response with our use of anti-bacterials and our hyper-cleanliness and how a little dirt and allowing our immune system to actually do its job will make us healthier in the long run. She shows that the use antibiotics, except in the most serious cases, actually weakens our immunity and how your immune system tends to become lazy and ineffective if it isn't given a job. She also explains the importance of vaccinations. Explained in simple terms and accompanied by cartoons, this book is a super quick read and based in solid scientific evidence. I give it four stars only because it is less an actual book and more like a hard-bound essay it is so short.

After taking an hour to read this book front to end, I found myself taking a deep breath and resolving to follow the advice laid out in this book, despite my germ-o-phobia, that is how convincing and solid this book is.

I would recommend this book to anyone curious about "Why dirt is good", but particularly those with babies or parents-to-be, as that is the primary audience that this book is aimed at. Not only will you find yourself having a better understanding of how our immune system works, you will find yourself better armed to deal with the day to day life with germs.

Its a short book, but full of interesting and helpful pieces of knowledge. the material was presented very clearly and concisely, most of it in terms that normal people can comprehend. it explains clearly how normal household germs strengthen the immune system, and how the ultra hygienic times we live in can actually weaken it and increase allergies to common items. every germophobe should study this from end to end! germs are good!

There would be a lot less sick kiddos out there if all moms would learn to understand the scientific reasons for letting your children get dirty and enjoy being a kid!
