For the last week I have had a cold. I usually get one each winter. I have two kids in school and they bring home a lot of viruses. I also work in a hospital, which tends (for some reason) to have lots of sick people. Although this year I think I caught my cold while traveling. I’m almost over it now, but it’s certainly a miserable interlude to my normal routine.
One thing we can say for certain about the common cold — it’s common. It is therefore no surprise that there are lots of cold remedies, folk remedies, pharmaceuticals, and “alternative” treatments. Finding a “cure for the common cold” has also become a journalistic cliche — reporters will jump on any chance to claim that some new research may one day lead to a cure for the common cold. Just about any research into viruses, no matter how basic or preliminary, seems to get tagged with this headline. (It’s right up there with every fossil being a “missing link.”)
But despite the commonality of the cold, the overall success of modern medicine, and the many attempts to treat or prevent the cold — there are very few treatments that are actually of any benefit. The only certain treatment is tincture of time. Most colds will get better on their own in about a week. This also creates the impression that any treatment works — no matter what you do, your symptoms are likely to improve. It is also very common to get a mild cold that lasts just a day or so. Many people my feel a cold “coming on” but then it never manifests. This is likely because there was already some partial immunity, so the infection was wiped out quickly by the immune system. But this can also create the impression that whatever treatment was taken at the onset of symptoms worked really well, and even prevented the cold altogether.
What Works
There is a short list of treatments that do seem to have some benefit. Nonsteroidal anti-inflammatory drugs (NSAIDs), like aspirin, ibuprofen, and naproxen, can reduce many of the symptoms of a cold – sore throat, inflamed mucosa, aches, and fever. Acetaminophen may help with the pain and fever, but it is not anti-inflammatory and so will not work as well. NSAIDs basically take the edge off, and may make it easier to sleep. Read more »

Yoga is good for your mind and body, including your skin. Yoga mats, on the other hand, might not be. Using someone else’s yoga mat for an hour could lead to an infection.
Fungal infections are common and appear as athlete’s foot, toenail fungus, and ringworm. Unfortunately, the fungus can survive on surfaces like mats long after the infected person has left. Although most people blame the gym locker room when they develop athlete’s foot, you can catch the fungus from a variety of places anytime you walk barefoot.
Fortunately, even if the fungus comes into contact with your skin, it doesn’t always lead to infection. Dry, cracked skin, or soft, wet skin disrupt your primary defense against the fungus — the densely packed barrier of skin cells, oils and proteins on your healthy skin’s surface. Here are five ways to prevent taking a fungus home with you from your next yoga class:
1. Bring your own mat. At least you know what you have.
2. Use an alcohol sanitizer on your hands and feet after your class. Sanitizers with at least 60 percent alcohol are excellent at drying up the fungus and killing it long before it has a chance to infect you. Read more »

A friend suggested she was tired of hearing about vaccines. Her comment and our subsequent conversation seemed to reflect an important shift in parent sentiment: The conversation about vaccines is beginning to get somewhere.
While much of this was born of the mainstream media’s newfound realization that the vaccine-autism connection was cooked, some of this is due to the tireless work of those like the Children’s Hospital of Philedelphia’s Dr. Paul Offit who get the story right.
As part of his passionate agenda to expose vaccine truths, he’s published “Deadly Choices: How the Anti-vaccine Movement Threatens Us All” (Basic Books, 2011). For those looking to understand the origins of anti-vaccine sentiment, read this book.
What struck me is the deep history behind the anti-vaccine movement. From Jenner’s smallpox fix to modern-day MMR struggles, Offit draws fascinating corollaries surrounding immunization that seem to defy the generations. Vaccine resistance was not born of Andrew Wakefield, but broader concerns rooted in religion, individual liberty, fear and propaganda. ”Deadly Choices” puts the anti-vaccine movement in a historic sequence that reads like good suspense. I couldn’t put it down. Read more »

Luc Montagnier received the 2008 Nobel Prize for his discovery of the human immunodeficiency virus (HIV), but now he’s come up with a more-than-strange theory. He thinks DNA can teleport from one tube to another via electromagnetic signals. Is this the so-called “Nobel disease?”
French virologist Luc Montagnier stunned his colleagues at a prestigious international conference when he presented a new method for detecting viral infections that bore close parallels to the basic tenets of homeopathy.
Although fellow Nobel prize winners — who view homeopathy as quackery — were left openly shaking their heads, Montagnier’s comments were rapidly embraced by homeopaths eager for greater credibility.
Montagnier told the conference last week that solutions containing the DNA of pathogenic bacteria and viruses, including HIV, “could emit low frequency radio waves” that induced surrounding water molecules to become arranged into “nanostructures.” These water molecules, he said, could also emit radio waves.
He suggested water could retain such properties even after the original solutions were massively diluted, to the point where the original DNA had effectively vanished. In this way, he suggested, water could retain the “memory” of substances with which it had been in contact — and doctors could use the emissions to detect disease.

One of our readers suggested that I review the book The Great Influenza: The Epic Story of the Deadliest Plague in History, by John M. Barry. It’s not a new book (it was published in 2004) but it is very pertinent to several of the issues that we have been discussing on this blog, especially in regards to the current anti-vaccine movement. It’s well worth reading for its historical insights, for its illumination of the scientific method, and for its accurate reporting of what science has learned about influenza.
In the great flu epidemic of 1918, influenza killed as many people in 24 weeks as AIDS has killed in 24 years. It’s hard to even imagine what that must have been like, but this book helps us imagine it. It tells horror stories: Children found alone and starving beside the corpses of their parents in homes where all the adults had died, decomposing bodies piling up because there was no one left who was healthy enough to bury them.
Sometimes the disease developed with stunning rapidity: During one three-mile streetcar trip, the conductor, three passengers, and the driver died. In another incident, apparently healthy soldiers were being transferred to a new post by train: During the trip, men started coughing, bleeding, and collapsing; and by the time it arrived at its destination, 25 percent of the soldiers were so sick they had to be taken directly from train to hospital. Two-thirds of them were eventually hospitalized in all, and 10 percent of them died. The mind boggles. Read more »
