Best Drug Ever: Exercise

Fountain of Youth

I have long said that exercise is a panacea and a cure-all, but new research has just backed up my claim. I find it funny to think that Ponce De Lion, the legendary explorer who went off in search of the fountain of youth, actually found the elixir to long life, only it wasn’t a fountain at all, but the exercise he was getting looking for the fountain.

Joy of Exercise

Exercise is a powerful way to change how you feel and it can actually alter or reverse many diseases. If exercise were a drug, doctors couldn’t keep it on the shelf; the incredible part about the exercise story is that this “drug” is free and has virtually no side effects.

The importance of exercising is best summed up with this quote:

The Global Burden of Disease Study initiated by the World Health Organization included physical inactivity among the most important risk factors threatening global health. A sedentary life style may be as detrimental to health as smoking.(1)

Read that again! That quote is saying that not exercising has the same bad health effects as smoking. Clearly you have to get up off your butt and start moving it around some.

Let’s take a look and see just how powerful of a drug exercise is.

Health Benefits of Exercise

The research supporting the benefits of exercise is enormous and the following are just a sample of what is out there.

  • Cardiovascular Disease: Exercise improves heart function, blood flow to the whole body, nervous system control over the heart, and a technical measurement called endothelial function in patients with heart disease.(2) It appears from a large number of studies that exercise can help prevent heart disease. Exercise even helps people who have had a heart attack, reducing symptoms, complications, trips back to the hospital, and longer life. Not only that, but their quality of their life is better, they have lower depression, and they return to work or active life quicker than people who don’t exercise.(3)
  • High Blood Pressure: The good news is that high blood pressure appears to respond best to moderate exercise (as opposed to strenuous exercise). With as little as 30 minutes of continuous exercise a day, patients are able to reduce their high blood pressure. It is important to note that the kind of exercise is important: continuous. Continuous exercise is walking, running, biking and not tennis, golf or even soccer or basketball.(4) The jury is still out if weight training or high-intensity exercise will help high blood pressure.
  • Rheumatoid arthritis: Moderate exercise has been shown to improve the symptoms (less pain) and the functional ability (they can do more) in people with rheumatoid arthritis.(5)
  • Diabetes: Exercise has been studied in diabetics for a long time and has been shown to improve blood sugar control and reduce the need for medications. In a new study on the effects of exercise in diabetics, researchers were able to prove that long-term blood sugar control (by measuring hemoglobin A1c) is much better in diabetics that exercise than those that don’t, even when there they didn’t lose weight because of the exercising.(6)
  • Weight Loss: As you can guess, exercise and weight loss has been extensively studied. A new study on overweight children showed that exercise helped them (more than adults) maintain their weight loss over a long period of time.(7) This study is so important and demonstrates that exercise can become a habit if introduced early enough in someone’s life. While normal-weight people should exercise at least 30 minutes (moderate intensity) on most days; overweight people should exercise 60 to 80 minutes a day.(8)
  • Cognitive function: There is pretty good evidence that exercise will help maintain brain function, including memory, cognitive function, and attention in older adults. Since Alzheimer’s (and dementia in general) are becoming such a health disaster, it is good to know that exercise can be preventive.(9)
  • Depression and Anxiety: A prescription for exercise often works better in people with depression and anxiety than taking a drug. New research suggests that this effect may be due to the ability of exercise to help us deal with stress.(10) Who couldn’t use a little stress and anxiety reduction?

What Else?

Exercise has been show to:

  • Improve self-esteem, especially in children.(11)
  • Reduce the risk for colon cancer.(12)
  • Improves our quality of life, especially in older people.(13)
  • Reduce back pain.(14)
  • Prevent osteoporosis.(15)

Move Your Buns Around

Okay, I didn’t quite tell you the truth above, there are side-effects from exercise and you can hurt yourself; luckily, though, most of the damage you can do is only temporary (unlike some drug damage).

Here is what you need to know to get started on your own exercise program:

  • Always check with your health care provider before starting an exercise program.
  • You don’t have to kill yourself; moderate exercise is what has been shown to be the most effective for most conditions.
  • Start slow and build up to 30 minutes every (or most) days. You’ll want to do more if you are overweight.
  • Pick a continuous exercise: this means your heart rate is up for a sustained period. Choose exercise like running, walking, cycling, cross-country skiing and others.
  • Consider adding weight lifting into your program.

Most of all, you want to have fun and stick with it. Yes, it can be a drag putting on clothes and getting out the door in the rain and snow, but most people love their exercise once they get going. If you can’t exercise outside, I recommend that you “pay” for the television that you watch by putting an exercise bike or a treadmill in front of the TV.
