Winter can be tough on the body, with increased rates of respiratory diseases and cardiac events, but cold weather also helps stimulate the body's calorie-burning fat. Dutch researchers reported findings in The New England Journal of Medicine in 2009 that showed that moderately cool temperatures of 61? F activated brown fat in 23 of 24 study volunteers. No one is suggesting that cold weather be used for dieting purposes (not yet anyway). But when we get chilled this winter, we may take some consolation that at least we're firing up those brown fat cells.
Research appears to support the idea that a regular dose of
vitamin D helps improve strength and balance in older people,
which helps reduce the incidence of falls.
It is not always easy to tell whether an oncoming illness is a
cold or the flu, but the symptoms do differ, and this chart can
Researchers from Harvard found that people with certain types of
colon cancer who took aspirin were less likely to die of the
Age brings increased likelihood of tooth decay, gum disease, and oral cancer. While there's not much you can do to stem the natural attrition of the tooth surface, the pillars of cavity prevention — brushing, flossing, and regular cleanings at the dentist's office — remain the same at any age and can keep the mouth healthy longer.
Prepping for a colonoscopy is unpleasant, but the bowel needs to
be clear for the procedure to be effective. Split dosing
and some new liquids may make the bowel cleansing needed for
colonoscopy a bit easier and perhaps more palatable. A variety of
flavorings (cherry, citrus-berry, lemon-lime, pineapple) are on
today's bowel prep menu, as are solutions without sodium sulfate,
which produces a rotten-egg flavor. There are also combination
approaches that start with laxative pills and then finish the job
with two liters of solution, instead of the usual four liters (a
liquid liter is just a little more than a liquid quart).
Meanwhile, colonoscopy guidelines were revised in 2008 to
recommend a so-called split dosing strategy: about half of the
liquid prep the day before the examination and the other half the
day it's scheduled, instead of all of it the day before.
I am 85 and have taken an 81-mg aspirin each day for decades for
heart attack prevention. Recently, I noticed these words on the
label: "Stop using if you get ringing in your ears or loss of
hearing." Should I be worried?
I have heard that doctors feel men over 60 shouldn't be treated
for prostate cancer because they're old enough that they are
going to die anyway. Is that so?
