August 6, 2000- Muscle Up Your Mind
The next time you curl up with a good book, you may be working out more than your creative imagination.

Research shows that not only can reading yield beneficial structural changes to the brain, but it also may play a role in delaying the onset of cognitive decline as you get older. Education and the continuous use of the brain have been shown to decrease that amount of cognitive decline associated with Alzheimer's disease and aging. As with any muscle in the body, when it comes to your brain, "use it or lose it" certainly applies.

August 13, 2000- Beat the Summer Heat
Now that summer is in full swing, make sure you know the best ways to beat the heat.

Record-setting temperatures can prove deadly for some people. To keep your cool--and protect your health when the mercury soars--wear lightweight, loose clothing, and a wide-brimmed hat. Also, avoid peak heat hours if you're going to exercise outdoors--or better yet, make your way to an air-conditioned gym. Be sure to stay hydrated. You may need more than your usual daily 6 to 8 glasses--especially if you're working out. Don't forget that fresh fruits and veggies also are good sources of water. Finally, don't wait until you're thirsty to drink; by then, you may already be mildly dehydrated.

August 20, 2000- Calcium Conundrum
You know you've got to get your calcium. But, do you know which formulation of calcium is best for you?

There are two different forms of calcium commonly found in calcium supplements: calcium citrate and calcium carbonate. As it turns out, citrate appears to be the better choice. In a recent study from the University of Texas Southwestern Medical Center, researchers found that calcium citrate had an absorption rate 2.5 times faster than calcium carbonate. Calcium is important for strong bones and teeth, and has also been shown to reduce the risk of heart disease and colorectal cancer.

August 27, 2000- Walk This Way
Ever wonder which one is better for you: several short bouts of exercise or one long workout? Both are helpful, but taking the long way just may do your heart more good.

A recent study examined the cholesterol levels of people who participated in an 18-week walking program. Participants took either one 20- to 40-minute walk, two 10- to 15-minute walks, or three 5- to 10-minute walks per day. The results showed that those people who took the single, longer walk had lower cholesterol levels than those who walked for a shorter duration more frequently.

Of course, if your schedule more easily accommodates two or three shorter walks, by all means, take them. The most important thing is to get moving.
