Dehydrated, cramped, limping? on a bike. Road nationals 2010.
People who exercise outdoors face a new threat.
It’s unrelenting.
Consistent.
Inescapable.
Perhaps, even more dangerous than distracted or mean motorists.
It’s the heat. Gosh, is it hot. If only I had a dollar for every time I heard someone say, “Doctor M, you aren’t riding in this heat; are you?”
Well…Other than the fortunate souls smart (or lucky) enough to live in cooler climates, most of us are facing an extreme wave of hotness. As a Kentuckian, I live in the epicenter of this summer’s cauldron. Louisville sits in a wind-protected valley alongside the heat sink that is the Ohio River. Think hot and steamy.
The excessive heat smacked me hard last evening. Normally, my highly-veined skin and northern European heritage serves me well in the heat. But last night, while riding in sight of our city’s skyline, it started: My mouth grew dry and my breathing labored. And why was that helmet feeling so tight? Next came the sensation of tingles—not the pleasant kind of tingles, like when your teenager hugs you. And then came the deal-breaker: chills. I stopped, swallowed my pride and called for a ride home. (Here’s an always for you all: When it’s ninety degrees out and you feel cold–stop exercising, immediately.)
After last night’s brush with heat exhaustion, I thought it reasonable to ramble on about the dangers of exercising in the heat. And of course, I will offer some nuggets of wisdom for beating the heat. Read more »

At a Harvard Medical School talk on migraine and food, a nutritionist from Harvard-affiliated Beth Israel Deaconess Medical Center delivered a message that people in the audience probably didn’t want to hear: “There are no specific dietary recommendations for migraine sufferers,” said Sandra Allonen. But she did have some advice to offer—and she emphasized that the connection between food and migraine is a very individual one.
Several foods have been associated with triggering migraine. None of them has been scientifically proven to cause migraines, explained Allonen, but many people report a link between eating these foods and getting a migraine. Possible migraine triggers include: Read more »

My stimulant of choice is coffee. I started drinking it in first-year university, and never looked back. A tiny four-cup coffee maker became my reliable companion right through graduate school.
But since I stopped needing to drink a pot at a time, an entirely new category of products has appeared — the energy drink. Targeting students, athletes, and others seeking a mental or physical boost, energy drinks are now an enormous industry: From the first U.S. product sale in 1997, the market size was $4.8 billion by 2008, and continues to grow. (1)
My precious coffee effectively has a single therapeutic ingredient, caffeine. Its pharmacology is well documented, and the physiologic effects are understood. The safety data isn’t too shabby either: it’s probably not harmful and possibly is even beneficial. (I’m talking about oral consumption — no coffee enemas. Please.) In comparison, energy drinks are a bewildering category of products with an array of ingredients including caffeine, amino acids, vitamins, and other “natural” substances and assorted “nutraceuticals,” usually in a sugar-laden vehicle (though sugar-free versions exist). Given many products contain chemicals with pharmacologic effects, understanding the risks, signs of adverse events, and potential implications on drug therapy, are important.
So are energy drinks just candied caffeine delivery systems? Or are these syrupy supplements skirting drug regulations?
The Message
The ads are seductive. Who doesn’t want more energy? Who doesn’t want their mind and body “vitalized?” And don’t we have time-starved lifestyles? Initially envisioned for athletes, energy drinks are now marketed mainly towards teens and young adults, where uptake has been dramatic. Cross-promotion with extreme sporting events, and creating names like “Full Throttle,” “Rockstar,” and even “Cocaine” burnish the “extreme” image. The market is now segmented further with products targeted at women, vegetarians, diabetics, celiacs, and more. However you identify yourself, there’s probably an energy drink developed with you in mind. Read more »

Nurses and doctors depend on coffee to perform their jobs the most of any profession, reports a survey.
Nurses ranked first and doctors second when asked if they needed coffee to get through their day. The rest of the coffee-fueled careers were a mixed bag of white collar and blue collar positions. Among other findings:
– 48 percent of those in the Northeast said they were less productive without coffee, compared to 34 percent of Midwesterners.
– 40 percent of those aged 18 to 24 said they can’t concentrate as well without coffee.
– 37 percent said they drink two or more cups a day.
NOTE: The study was funded by CareerBuilder and Dunkin’ Donuts.

Last week a popular TV talk show featuring a bunch of doctors (I’m not naming names) discussed how coffee grounds can improve cellulite. They explained how rubbing coffee grounds into your skin imparts caffeine into the cellulite thereby improving the circulation and drawing the toxins out.
This is a great tip, except that rubbing coffee grounds on your skin does not impart any caffeine into it, and there are no toxins in cellulite.
Cellulite is a normal secondary sex characteristic of women. It is the result of thin connective tissue in women’s skin. Massaging the cellulite (with coffee, tea, grapes, cream cheese, or chocolate frosting) pushes the fat back into the skin, temporarly improving the appearance. There is no science behind using coffee to treat this normal condition.
Scientific studies have shown, however, that carrying a wet coffee filter filled with grounds into your bathroom will burn more calories, because you’ll spend 20 minutes later cleaning up the mess in your shower.
