Energy Zappers 

1. Dehydration
Your extreme fatigue might be coming from hidden sources. Nixing these spirit-depleting factors from your life will automatically help reboot your verve.
It turns out that even moderate dehydration (which results in the loss of 3 percent of your body weight) can make you feel mentally sluggish and mess with your concentration. The next time you're feeling foggy or lightheaded, don't just assume you're in serious need of some food. Try downing a glass or two of water.

2. Cell Phones
Checking your cell before bed amps up brain activity, making it harder to doze off. Plus, any electronic gadget's artificial blue light can suppress the sleep hormone melatonin. A 2011 poll by the National Sleep Foundation found that 20 percent of people ages 19 to 29 are awakened by a call, text, or e-mail at least a few nights a week. Power it down well before bedtime.

3. Medication
Many drugs have veiled energy-sapping side effects. Chief among them are some classes of antidepressants and certain beta-blockers used to prevent migraines or treat high blood pressure. If you start a new med and feel more lethargic than usual, see doctor Bert for an alternative. (If there isn't one, take your dose right before bed.)

 4. Overtraining
While working out zaps the stress hormone cortisol, prolonged sweat sessions--like, for example, regularly running for more than 30 minutes at a steady rate--can actually rev cortisol production. Interval training (bursts of intense activity) combined with strength training (free-weight and body-weight moves) helps keep cortisol in check.

5. Low Iron
The mineral shuttles oxygen around your body and removes waste from your cells. If you're not getting around 18 milligrams a day, your body struggles to function properly and you can feel worn out; low iron levels in your diet can cause iron deficiency anemia. If you feel sluggish, call our office and ask for a simple blood test to see if you should be taking a supplement.

Connective Tissue - Use It or Lose It

What's so good about regular exercise? Apart from the well-known and significant cardiovascular benefits, regular exercise helps you maintain, strengthen, and continually upgrade your store and supply of connective tissue - muscle and bone.

Weight-bearing exercise is the key. One of the primary structural purposes of bone is load-bearing. Your long bones are designed to support the weight of your body and carry that weight around in three-dimensional space. Your skeletal muscles (voluntary muscle) support the functions of bone. Muscles are the tissues that move bones and joints. The bones passively bear the loads and the muscles actively move around those weight-bearing loads.

But your body is very smart. If you're not doing enough physical work your body will begin to break down muscle and bone tissue and use those biochemical components elsewhere, where the need is greater. In order to maintain the optimal health of your muscles and bones, you need to do sufficient exercise - regularly and ongoingly.

Just like the well-known, best-selling American truck, your body is built to last. But if it's built to last, why do so many people have serious problems with their bodies? If a human body is built to last, why does it seem to break down so easily?

The pharmaceutical industry earns billions of dollars each year, profiting from the tendency of so many people to suffer from debilitating disease. For example, osteoporosis affects more than 10 million women in the United States. The disorder involves loss of bone mass and may lead to fractures of the hip and lumbar vertebras, both of which may have severe consequences. In June 2010 a new drug was approved by the FDA to help prevent such fractures in postmenopausal women.

It is estimated that 55% of all Americans older than age 50 either have low bone mass or have lost sufficient bone mass to have received a diagnosis of osteoporosis.1 But if our bodies are built to last, why is the prevalence of osteoporosis so high? It doesn't make sense that our internal systems are simply designed to fail.

It is much more likely that our bodies are designed to withstand a tremendous amount of wear and tear. Human bodies are self-healing, self-renewing, and self-replicating machines. A human cell's most basic survival systems are based on deep complexity. Yet once a woman reaches menopause she joins a group of individuals at risk for losing a significant amount of bone mass and developing osteoporosis. What is wrong with this picture?

The hidden factors, revealed only upon close analysis and understanding, relate to lifestyle - what it is that we're doing with our bodies. If your driving style consists of flooring the accelerator and alternately slamming on the brakes, you'll quickly burn out the brake lines and ruin the tires of your fine built-to-last truck. If you rarely change the oil and oil filter your truck's performance will seriously degrade. If you ignore traffic signals and highway signs you'll probably crash your vehicle.

Defective care and maintenance and dangerous driving will drastically shorten the useful lifespan of your truck. The truck may be built-to-last but you've effectively voided the warranty. The day will quickly come, much sooner than anticipated, that you'll be forced to junk your truck.

This extended metaphor is exactly analogous to how we live our lives. Much recent research demonstrates that lifestyle is responsible for a large proportion of all cases of cancer, heart disease, and diabetes. For example, 82% of coronary deaths in women may be related to individual health behaviors.2 The main strategy to prevent loss of bone mass and osteoporosis is to engage in regular vigorous, weight-bearing exercise.3

From a broader perspective, the main strategy to preventing disease in general is to eat a healthy, diverse diet, do vigorous exercise regularly, get sufficient rest, and ongoingly engage in rewarding, fulfilling activities with family and friends. Our bodies are built to last. How long they last, to a large extent, is up to us.
