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.

Viscoelasticity: The Hidden Ingredient

Regular Chiropractic Care and Spinal Health
Spinal health depends on many factors. Positive benefits are obtained with regular physical activity and exercise. Negative predictors of spinal health include high levels of psychosocial stress as well as a sedentary lifestyle. The majority of these externals are under our control, to a greater or lesser extent. We may choose to make a shift in a sedentary way of living by committing to a program of regular physical activity. We may choose to help manage our stress by beginning a series of yoga classes or starting a meditation practice. Regular chiropractic care can help us significantly in all these activities by addressing internal factors that impact spinal health.

Physiologically, spinal health depends on the ability of spinal vertebras to move freely throughout a full range of motion. Spinal misalignments negatively impact this ability, restricting spinal motion and causing nerve interference. Nerve interference irritates spinal muscles, further restricting mobility. Regular chiropractic care detects and corrects these spinal misalignments, helping restore optimal nerve system function and optimal spinal health. By helping return your spine to good health, regular chiropractic care helps you achieve long-term overall good health and wellness.

Most of us have experienced a painful bout of low back pain brought on by a seemingly innocuous movement such as bending over to pick up a pencil or a dropped set of keys. These painful episodes may last a couple of days or be more severe and last more than a week. We're left wondering, "What exactly happened?" After all, we weren't trying to pick up a 100-pound crate. When our chiropractor asks what caused the problem we say, "I don't know. I didn't do anything." For the patient, the mystery often remains unsolved. But it's important to know there is an answer. The deep background to these unexpected, troublesome back problems is loss of viscoelasticity.

Viscoelasticity is a physical property of both materials and soft tissues. When these structures undergo deformation, they exhibit properties of viscosity and elasticity. Materials and soft tissues that demonstrate viscoelasticity resist shearing forces when a stress is applied (viscosity) and strain when stretched or compressed and quickly return to their initial state after removal of a transient load (elasticity). For viscoelastic structures, the relationship between strain and stress depends on the factor of time.

In terms of spinal biomechanics, viscoelastic structures include joint cartilage (for example, intervertebral discs), ligaments, and tendons.1 If a substantial load is placed on the low back when viscoelastic properties of intervertebral discs and spinal ligaments have not returned to optimum, injury to low back muscles and ligaments may result.2 For example, if you've been sitting for more than 15 minutes the soft tissue structures of your low back have been compressed for that length of time. Standing up and bending over to retrieve something causes your low back to attempt to support all the weight of your torso and head. If you haven't prepared your low back to receive this substantial burden, that is, restored viscoelasticity, you will likely suffer an injury that may be not only very painful but also inconvenient in terms of time and resources spent on recovery.

Injury prevention in these circumstances largely depends upon understanding.3 Being aware of the requirements for maintaining viscoelasticity will help you remember to "wake up" the soft tissues of your low back prior to any load-bearing activities such as bending over or twisting and turning. A simple way to restore viscoelasticity is to pause before suddenly changing a position you've been in for a while, such as getting out of a chair after working at your desk for 30 minutes, and gently rotating your torso from side to side eight or ten times. These rotational movements immediately restore viscoelastic properties to baseline and increase circulation to intervertebral discs, muscles, and ligaments. The result is a spine that is ready for action and prepared for the demands of new physical work. As always, proper preparation and attention help prevent injury.
