How Light Bulbs Make Us Fat…

It’s true. It’s Edison’s fault. While technology has advanced our species it has also impacted eons of evolutionary progress. Few people understand the connection or how the process of invention can have a negative effect on our health, but I can’t help but sense their related connection.

For example, “circadian rhythm” is a term used to describe the internal clock regulating the activities all living creatures perform throughout a 24-hour day. While this internal clock may differ, some animals are nocturnal while others are active during the daylight hours, the circadian rhythm reigns supreme over everything within the body like temperature, appetite and energy level. It’s the reason why some people can regularly wake up at a specific time without the use of an alarm clock.

Before Edison’s miraculous invention came about, our human circadian rhythms were closely matched with the 24 hour cycle found in nature. We got up with the Sun and slept when it went down. By nature, and extensive evolutionary history, we developed a close relationship with 24 hour days.

When the Miracle at Menlo Park introduced the world to a light source that was able to make a room almost as bright as the day, we no longer had to squint under the dim light of torches, gas lamps or candles. We were now able to see greater distances and perform tasks that had been previously reserved for the brighter light of day.

Here is the problem: our bodies depend on light levels to determine when to release some of the many hormones that drive our behavior and our health. This ability is solely dictated by our circadian rhythms which developed with the sunlight cycles.

Let me fast forward to a 21st century example. We’ve all experienced late nights; times you stayed up to watch a movie, TV or surf the Internet. These seemingly harmless pursuits expose us to light sources during times the body thinks it should be sleeping, thereby disrupting our natural circadian rhythm.

Over time, this disruption can limit your immune system’s efficiency and interfere with the regulation of your body temperature which closely relates to your metabolism, too. Although there is no harm in the occasional late night, if made a habit, late night activities can derail the body’s ability to recover from daily stress. Stress releases Cortisol and Cortisol can make the body store fat. Hence: light bulb = fat.

Ok. Maybe I jumped the gun on my logic there, but the truth really isn't that far off. The negative impact on our circadian rhythms by modern technology is being researched by numerous organizations, with a general consensus that has not been positive.

So, while I would like to blame my extra pounds squarely on Edison and his invention; the light bulb, I must be fair. It really isn't his fault. I know that. It is up to me to develop a responsible way in which to continue to benefit from modern advances while maintaining balance with nature. After all, the Sun is not going away anytime soon. And, neither is my circadian rhythm.

As always – Enjoy Your Life,

The Benefits of Regular Massage Sessions

Once people discover the many joys and benefits of massage, a common question arises—“How often should I schedule my massage sessions?”

Of course, there is no set answer, but studies indicate that massage at regular intervals is most beneficial to your overall health.

In a Newsweek article entitled “The Magic of Touch,” the advantages of frequent massage are considered. The following excerpts help to answer the question, “How often?”

“A weekly massage may seem an indulgence, but new research suggests it can have major health benefits...

“Since instituting a program of massage, job-specific exercises and ergonomics in 1990, the Virginia-based company [Wampler Foods] has cut repetitive-stress injuries by 75 percent...

“From assembly lines to corporate headquarters, Americans are discovering the magic of massage. At Boeing and Reebok, headaches, back strain and fatigue have all fallen since the companies started bringing in massage therapists...

Should You Take Supplements?

Often I am asked about supplements and their role in a healthy diet. My take is that while vitamins and minerals are essential to life, the human body cannot self sustain this requirement. Therefore, it is imperative that we eat a well-rounded, low fat diet in order to obtain an adequate variety and supply.

Unfortunately, Americans have become infatuated with supplementation. Mega-dosing has become a common practice for both athletes trying to improve their performances and the “average Jane or Joe” trying to compensate for inadequate nutrition.

Research indicates supplementation is ineffective in improving athletic performance in a well-nourished adult. That’s to say if you are eating well, taking additional doses of supplements won’t give you an edge.

In fact, excessive amounts of fat soluble vitamins (vitamins A, D, E and K) may prove toxic since they are stored in the body and not easily excreted. Even some water soluble supplements such as vitamin B-12 have been shown to cause toxi…

What To Do When You’re Chronically Stressed

Of all the modern-day ailments that seem to affect us, none is more pervasive than stress. Everywhere you turn, there are factors lurking to redirect you from your peaceful pursuit of happiness and lock you in the clutches of “stress.”

What exactly is stress—and what more insidious effects does it cause? The dictionary defines stress as “great pressure or force; strain.” In today’s world, we think of stress as the result of too much pressure laid upon us by life, causing mental worry or anguish. This, in turn, manifests itself in tight neck and shoulders, headaches, nervous stomach, etc. But these physical and mental conditions are really only the beginning.

Studies show that stressful situations can develop into more threatening health conditions. For instance:

A sudden or unexpected stressor can activate your adrenal glands, which sends adrenaline and other hormones into your bloodstream. This brings about an increase in your breathing, heart rate, blood pressure, and blood flow to…
