Dr. Berry’s findings, presented last week in San Francisco at the American Heart Association’s Annual Epidemiology and Prevention Conference, are based on an analysis of 1,765 men and women who had physical examinations performed during the 1970’s and 1980’s at the Cooper Institute, the Dallas-based birthplace of the aerobics movement. Put another way: If you’re not fit in your 50’s, your projected life span “is eight years shorter than if you are fit,” Dr. Berry says.

So regular exercise is the most cogent weapon we have to ward off illness and fight disease- as it results in lower blood pressure, healthier cholesterol, and lower blood sugar.

Rest assured… there is a silver lining to all this before you start jogging, digging ditches, or playing singles tennis:  Studies also indicate that exercise’s greatest impact occurs when individuals move from a sedentary lifestyle to embarking on regular moderate exercise regimens.

That’s encouraging. You go, Girl!

So what do we do to slow down? Here are some ways to manage your stress.

• Be realistic about your goals and keep things simple. If you offer to host the annual family Holiday party, don’t go over the top and self cater the entire thing. Take-out side dishes and salads are great fill-ins.

• Express your thoughts in writing. Keeping a journal, blog or diary can be very therapeutic. And if you are not keen of the pen, try recording yourself via a digital voice or video recorder.

• Incorporate some form of exercise into your day and be consistent about it. You don’t have to run the marathon; take a walk with a friend, join the pool at the local Y or shoot some hoops with your kids.

• Massages are the ultimate relaxant. If you don’t believe me, try one for yourself. An aside, did you know that despite the gloomy economy – massage therapy has remained quite popular according to a recent survey from the American Massage Therapy Association?

• Find out if your workplace has any stress-fighting resources in place. Many Employee-Assistance Programs (EAP), wellness programs or health plans provide confidential personal stress-relief plans.

“Having a routine gives you a sense of control over the day,” says Ian A. Cook, MD, director of the Depression Research Program at UCLA. “We know that helps, and we know that not having a sense of control makes people feel worse.”

– Exercise is proven to be a great mood-booster.

– A basic healthy eating plan will do wonders.

– Get a good night’s sleep.

– Set realistic goals daily and try to meet them.

– Incorporate some downtime for fun or relaxation into your schedule.

– Have a support network of family and friends and don’t distance yourself from them.

– Make sure you have some responsibilities that give you a sense of accomplishment and keep you active.

– Try a natural supplement such as fish oil, but only after checking with your doctor.

– Stay away from substance abuse.

– When you’re in a rut, go out of your way to try something new and different. Push yourself to go to a museum . . .Volunteer at a soup kitchen . . . Take a language class. . .

Here are some cognitive ways to fight automatic negative thinking:

– Use logic when you have exaggerated terrible thoughts about yourself.
“Try to impose some reason,” says Cook. “Inject some reality.” Is it really true that no one likes you? Is there real evidence for that? Sure, you might feel like the most stupid and hateful person on the planet, but really, what are the odds?”

– Clear your head of negativity by taking a break. Breathing exercises or a simple walk around the room can help.

Just remember not to ignore serious signs of depression. If you’re not functioning make sure to get professional help.

Wives who cared for husbands with dementia were nearly four times more likely to develop dementia than wives of men who didn’t have dementia, while husband caregivers in the same circumstances were almost 12 times more likely to develop the disease.

So what exactly is it that causes the risk of developing Alzheimer’s to skyrocket? You can’t catch it, can you? Researchers think the root cause is the stress that comes along with these caregiving situations.

Ralph Nixon, MD, PhD, a psychiatrist and Alzheimer’s disease expert at NYU and vice chairman of the Medical & Scientific Advisory Council at the Alzheimer’s Association feels that “the amount of stress involved in caring for a spouse with dementia is tremendous,and stress is a known risk factor for dementia.”

Healthy diet and exercise are key factors of good brain health, and both of these areas tend to falter when one is stressed out. It is critical that caregivers look after themselves properly, making sure to rest, to visit a doctor regularly and to maintain social ties.

Since men tend to rely on their wives to serve as the impetus for seeing the doctor and keeping up with friends and family, they are more apt than women caregivers to let these things slide when their spouse is cognitively impaired – thereby increasing their risk of high cholesterol, blood pressure and other conditions that can lead to dementia.

Today’s medical announcement would be astounding if it wasn’t almost intuitive; the results clearly demonstrate that lifestyle behaviors do contribute to stroke risk independently of the intermediate risk factors.

We are all aware that the following four behaviors are beneficial to one’s health. Physical activity, moderate alcohol consumption, no smoking, and the daily consumption of five or more servings of fruits and vegetables a day can only have a positive impact. The strength of that impact was recently bolstered by a defining EPIC (European Prospective Investigation of Cancer) study conducted in England.

20,040 men and women ages 40 to 79 had a physical exam and completed a detailed health and lifestyle questionnaire upon enrolling in the study. This data determined which participants smoked, drank, were physically active, and whether they ate their fruits and vegetables. The risk of stroke for those who did not practice any of the above mentioned behaviors increased twofold compared with individuals who adopted all four.

“These results provide further incentive and support for the notion that small differences in lifestyle can have a substantial potential impact on risk,” the authors concluded.

Relax actively. That’s the advice of researchers to the retired and the elderly. Not only is it beneficial for your heart, it’s beneficial for your mind.

This news is the conclusion of numerous studies concerning how exercise affects the brain. Exercise causes a chain of reactions that release chemicals into the bloodstream, while regular aerobic workouts build up the presence of these chemicals. The results are startling. Far from the usual shrinking that accompanies aging, the brain begins to grow.

Children have flourishing brains that branch out new neurons with an exuberant frequency. The adult brain begins trimming back unused neurons, and some also die on their own. Until these recent studies, scientists believed that these dead neurons could never regrow. Now they know differently.

In a study by Columbia University’s Scott Small and the Salk Institute’s Fred Gage, subjects asked to exercise regularly seemed to sprout new neurons; the more fit they became the more neurons they grew. The neurons appeared in the section of the brain dedicated to learning and memory, one of the first sections to age. “It’s not just a matter of slowing down the aging process,” explained Arthur Kramer, of the University of Illinois. “It’s a matter of reversing it.”

Exercise does more than just grow a bigger brain. A research group at the University of Washington found that people who exercise three or more times a week have a 30% lower risk of developing Alzheimer’s. Nor did the exercise have to be an intense aerobic workout. Lead researcher Dr. Eric Larson said that a 15-minute walk three times a week was enough to reduce the risk. A similar study found that five to six hours of vigorous physical activity each week led to a 40% decrease in risk of developing Parkinson’s Disease.

Scientists don’t know why this happens, and they haven’t yet zeroed in on the best exercises. But until they figure it out, one thing remains clear: being a couch potato is bad for the brain. So move!

Sometimes it seems like everything causes cancer. Then it seems like everything prevents it. What advice should you follow and what can you regard skeptically until further research actually proves something? Here are a few lifestyle tips for cancer prevention. All are well proven to correlate with reduced cancer risks.
1. A little alcohol affects men and women differently. Men actually benefit from a small daily intake of spirits, while women should not exceed a single drink a day, if even that much.
2. Avoid processed meats at all cost, and limit your consumption of all red meat. Fish and fowl are rich in all the proteins you need without the unhealthy fats that come along with.
3. Along the same lines, try to avoid overdosing on sodium and salt, which most people do. The average salt intake is already well above the necessary limit, so any reduction on your part can only be good.
4. Whole, unprocessed foods are your best bet. Fruits, veggies, and things that grow from the ground are healthy. Foods with ingredients you can’t pronounce or that don’t resemble any naturally occurring edible should be shunned. And while you’re at it, aim for a variety of veggies and fruits. Different foods have different vitamins and minerals, so take in as much as possible.
5.  Exercise. About 30 minutes of activity per day, enough to get your heart rate up, should do the trick.
6. Avoid fat, especially saturated and hydrogenated. Hydrogenated fats, found in margarine and most junk foods, are directly linked to cancer risks. Processed sugar is also a known evil. Reduce your calorie intake as much as possible, a strategy linked to longer life overall.

Some news from the science front! Hormone replacement in women is linked to hip replacement -  and childbearing is linked to knee replacement. These two new findings come out of England where 1.3 million women were followed since 1996.
Hormone replacement therapy is quite common among post-menopausal women, particularly those at risk of osteoporosis. Estrogen prevents bone-loss, which in turn prevents osteoporosis. But it seems to have a negative affect on join strength. Notable, estrogen with progestragen was more closely correlated with hip replacement than estrogen alone or tibolone.
The second finding is more startling. It’s well known that running, excessive jumping, climbing, and carrying heavy things can damage the knees, but nobody ever thought to apply that to carrying children. Though, when you think about it, some of those babies can get quite heavy.
This finding creates one of those tight corners often created by conflicting medical advice. Exercise during pregnancy is highly recommended, but it’s important to avoid unduly stressing the knees. Here are a few recommendations:
1. Swimming. Swimming takes the weight off your legs while getting your heart rate pumping. An outdoor pool or swimming no more than once a week because of the chlorine and ammonia that can build up over indoor pools.
2. Rowing, weightlifting (from sitting position), and similar exercises are healthy and will also get you ready to start carrying around a 10 lb baby.
3. Biking on a stationary bike will support your weight while giving you great aerobic exercise.
4. Yoga is both relaxing and healthy and a good idea any day.
