Duh

Exercise is good for you. Here's another reason, in case you didn't believe everything everyone's been saying for the last 40 years. Exercise turns bad, white fat cells into brown fat cells (which aren't just big clumps of stuff that take up space, but are active and use energy and metabolize), once thought to cease to exist in the human body after babyhood. I never knew "babyhood" was a word. But it makes sense. It's because exercise promotes the creation of something called PGC-1 alpha, recently dubbed "irisin," a protein that continues to benefit the body even once exercise has ceased.

But how muscle cells “talk” to fat, what they tell the fat and what role exercise has in sparking or sustaining that conversation have been mysteries — until, in the new study, scientists closely examined the operations of a substance called PGC1-alpha, which is produced in abundance in muscles during and after exercise.

“It seems clear that PGC1a stimulates many of the recognized health benefits of exercise,” said Bruce Spiegelman, the Stanley J. Korsmeyer professor of cell biology and medicine at the Dana-Farber Cancer Institute and Harvard Medical School, who led the study. Mice bred to produce preternaturally large amounts of PGC1a in their muscles are typically resistant to age-related obesity and diabetes, much as people who regularly exercise are.

But never fear, you who are exercise averse or immobilized from disease or injury -

In upcoming experiments, Dr. Spiegelman plans to study whether injections of irisin imitate some of the metabolic benefits of exercise in people who, because of disease or disability, cannot work out. He also hopes to elucidate just how much and what types of exercise produce the greatest natural irisin increases in healthy people.

Mass Health

Massachusetts is often at the leading edge of healthcare reform because of the high quality of its medical facilities, and therefore, the high cost of medical services and insurance in the state. Harvard Business School senior lecturer and Brookings Institution senior fellow, Robert Pozen, has articulated some good ideas in today's Boston Globe.

Everything in Moderation

Doctors are reticent when it comes to recommending that their patients consume alcohol regularly, worrying that it could lead to substance abuse. However, study after study shows that men should be drinking 2 alcoholic drinks per day and women should be drinking 1.

From those wicked smaht guys in Cambridge, Mass. -

"A study by Harvard University researchers suggests that... even among men who are models of health, moderate drinking was associated with a lower risk of heart attack. Those who had one-half to two drinks a day had the lowest heart attack risk -- 40 percent to 60 percent lower than healthy men who didn't drink. And that was true no matter whether they were drinking beer, wine or liquor."

"'These results tend to refute the oft-quoted hypothesis that lower coronary heart disease seen among moderate drinkers is due to their associated healthy lifestyle habits, and not to their alcohol consumption,' wrote Dr. R. Curtis Ellison, director of the Institute on Lifestyle and Health at Boston University School of Medicine, and co-author of a critique of the study." Read the article on MSN Health & Fitness.

Harvard Squash and Happiness

The following list comes from NPR's website. Just today, I heard Diane Rehm interview the Harvard professor who teaches the prestigious university's most popular class, "Positive Psychology".

Dr. Tal Ben-Shahar revealed during the interview that he was a varsity squash player in college, so I was pretty psyched to hear that. I looked him up and it turns out he was national champion in 1995 (he attended Harvard). Not bad.

I have found several references over the years to the idea contained in number 2, and I believe it to be extremely important.

I also think you should listen to NPR if you have any time to do so during your day. You'll learn a lot that you might never have heard about.

Six Tips for Happiness

Advice from Tal Ben-Shahar.

1. Give yourself permission to be human. When we accept emotions -- such as fear, sadness, or anxiety -- as natural, we are more likely to overcome them. Rejecting our emotions, positive or negative, leads to frustration and unhappiness.

2. Happiness lies at the intersection between pleasure and meaning. Whether at work or at home, the goal is to engage in activities that are both personally significant and enjoyable. When this is not feasible, make sure you have happiness boosters, moments throughout the week that provide you with both pleasure and meaning.

3. Keep in mind that happiness is mostly dependent on our state of mind, not on our status or the state of our bank account. Barring extreme circumstances, our level of well being is determined by what we choose to focus on (the full or the empty part of the glass) and by our interpretation of external events. For example, do we view failure as catastrophic, or do we see it as a learning opportunity?

4. Simplify! We are, generally, too busy, trying to squeeze in more and more activities into less and less time. Quantity influences quality, and we compromise on our happiness by trying to do too much.

5. Remember the mind-body connection. What we do -- or don't do -- with our bodies influences our mind. Regular exercise, adequate sleep, and healthy eating habits lead to both physical and mental health.

6. Express gratitude, whenever possible. We too often take our lives for granted. Learn to appreciate and savor the wonderful things in life, from people to food, from nature to a smile.
