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.

Cognitive Function and Chiropractic

One of the proposed mechanisms for the benefit of regular exercise on mental functioning involves alterations in the amount of blood reaching the brain. A complementary proposed mechanism involves alterations in the structure and function of the brain's own blood vessels.

The ability of regular exercise to stimulate growth of new blood vessels and strengthen and improve existing blood vessels depends, in part, on a properly functioning nerve system. Your nerve system supports the activity of all other body systems. It needs to be operating at peak levels in order for all other systems to operate at their peak levels.

Regular chiropractic care helps ensure the integrity and proper functioning of your nerve system, including your brain, spinal cord, and spinal nerves. By doing this, chiropractic care helps you get the most out of your exercise.

Many people experience lapses in memory as they get older. Every so often, it may become frustratingly difficult or even temporarily impossible to recall a particular word or a specific person's name. A person might commit a phone number to memory and then immediately forget it. Of course, everyone is familiar with the sinking feeling associated with the critical question "where did I put my keys?" For most people these glitches are minor, nothing more. However, for a certain percentage of older persons (approximately 10-20%), these lapses represent mild cognitive impairment.1 And for a proportion of these people, mild cognitive impairment will progress to Alzheimer's disease.

Normal aging can include instances of subtle forgetfulness such as having difficulty recalling words, not remembering where you put an important document, or leaving a full milk carton on the kitchen counter overnight. But the memory loss associated with mild cognitive impairment represents an actual condition, i.e., an actual disease entity. Such memory loss is more prominent. People forget important information such as meaningful telephone conversations, recent events that would normally be of interest, and dates and times of appointments.

In the early stages it may be challenging to differentiate mild cognitive impairment from the effects of normal aging. Some suspected cases of impaired mental activity may in fact represent treatable conditions such as depression and an underactive thyroid. People experiencing the significant memory problems associated with mild cognitive impairment may be expected to decline by about 10% each year. Risk factors associated with more rapid decline include a low metabolic rate in regions of the brain associated with memory and processing of information. More rapid decline is also associated with reduced size of the hippocampus, a seahorse-shaped structure located in the center of the brain which is important in memory, spatial memory, and navigation.

The good news is that people can take action on their own behalf to preserve and improve cognitive function. Numerous recent studies have shown that regular exercise provides a significant benefit in people with memory problems.2,3 For example, long-term improvements in cognitive function were obtained by walking for 50 minutes a day, three times per week. People exercising for 150 minutes each week had better delayed recall and they performed better on cognitive tests. Additionally, people doing moderate exercise had lower Clinical Dementia Rating Scores. In one study, a 6-month program of physical activity resulted in improvements which persisted over an 18-month period.

The message is clear. We want to have the opportunity to get older and we also want to live well. There are natural effects of normal aging, but we don't want other potential effects of aging to grind us down. Exercising is an important action step that has a wide range of benefits, including improved cardiovascular and respiratory function. We now know that exercise can also preserve and improve cognitive abilities. It's smart to do regular exercise to help us stay smart.
