A Continuous Glucose Monitor (CGM) is a tiny wearable medical device that accurately measures the amount of sugar (glucose) in your blood 24 hours a day.

These monitors track the user’s blood sugar levels close to real-time without resorting to the standard blood stick test using a glucometer. Please be aware that blood sugar and blood glucose mean the same thing and the terms interchangeably.

Blood glucose is measured in milligrams of glucose per deciliter of blood (mg/dL). Deciliter is 1/10 of a liter.

At first, you may think that Continuous Glucose Monitors (CGM) are only for diabetic or prediabetic (people prone to diabetes) needing better control of their blood sugar. Admittedly that is the target market. And before start-up digital health companies like NutriSense made…

Acupuncture is rooted in the belief that the balance of vital energy in your body influences your health.

An ancient Chinese medical practice call Acupuncture has been tested for weight loss. Acupuncture is rooted in the belief that the balance of vital energy influences a person’s health. When your vital energy is in balance, you’re healthy. Acupuncture helps balance a person’s vital energy by stimulating specific meridian points to promote circulation and healing.

Traditional acupuncture uses very thin needles to stimulate meridian points on the body. Meridian points are located all over the body, such as the face, chest, legs, or ears. For weight loss, acupuncture points on the ear are commonly used. …

Tinnitus affects approximately 15% to 20% of the population.

People suffering from tinnitus hear sound in one’s head or ears without the stimulus of external sound. Tinnitus affects approximately 15% to 20% of the population, with older adults being the most affected. 1

What are the indications of Tinnitus?

Tinnitus is characterized as a ringing in the ears despite the absence of external sound. Variations of Tinnitus include sounds, such as clicking, buzzing, humming, ringing, pulsating, or other auditory sensations. Tinnitus may affect one or both ears.

Red Light Therapy has been investigated for decades. Green Light Therapy (GLT) is beginning to emerge.

Green Light Therapy (GLT) is similar to Red Light Therapy (RLT). It’s a simple, non-invasive procedure using light. With GLT we are using green light with wavelengths between 515 nm and 540 nm.

Green light initiates biochemical reactions at the cellular level as does red light.

GLT for Skin Rejuvenation:

GLT slows helps with many skin issues. It is reported to help with redness and skin pigmentation, toning (tightness), and texture.

GLT for Migraines:

Many migraine sufferers are light-sensitive. Strong light intensifies their migraine pain. Which leads sufferers to rest in a darkened room until the migraine passes. In a light sensitivity study performed by…

Fear-Mongering 60 Hz EMF Using Baseless Assumptions

3.9 milligauss reading off RLT panel — photograph by author

Some companies are suggesting that EMF from RLT devices “may” be detrimental to your health.

Mains-powered devices and appliances generate low-frequency electromagnetic fields (EMF). We will focus on the lower, 50–60 Hz portion of the electromagnetic spectrum. EMF can occur at three different frequencies: extremely low frequency (ELF), moderate frequency (IF), and radiofrequency (RF).

How does ELF-EMF possibly affect the human body?

For many years the biological effects of EMF and its implications for human health have been a subject of intense public discussion. A situation fuelled by a series of epidemiological reports that reported harmful effects of EMF on human health.

According to some epidemiological researchers, 50/60 Hz electric and magnetic fields (ELF-EMFs) in the region of 0.3 to 0.4 uT (…

Some companies claim that LED light flicker in RLT “may” be detrimental to photobiomodulation therapy.

Some companies are claiming that light flicker in RLT “may” be detrimental to photobiomodulation therapy. To bolster their premise, some have gone back to the 1990s when a 12 Hz strobe effect placed in a broadcasted cartoon caused several children to become ill. However, how a 12 Hz strobe effect that may have caused seizures in children connects to a 120 Hz flicker in photobiomodulation eludes me.

First, flicker is not a stroboscopic light. A stroboscopic light turns off entirely then back on. This on-off cycle repeats rapidly.

Most people can not see the slight 120 Hz flicker in RLT…

Solar power meters are notoriously inaccurate for measuring light irradiance from red light therapy units, here’s proof.

Photography by Author

Solar meters are notoriously inaccurate for measuring light irradiance from red light therapy units. Solar meters are broad-spectrum devices designed to measure sunlight, hence the name “Solar Power Meter”. Yet despite this fact these solar power meters are inaccurate for measuring narrow bandwidth light radiation from RLT units you see many authors and even manufacturers (still) using these devices and quoting mw/cm² power levels. Some try to justify their usage by saying that they know the meter is inaccurate, but they are using it to check relative power levels between RLT units.

For a short amount of time, I sold…

RLT has been clinically shown to improve vision in older adults.


The retina ages faster than other organs in the body due to its high metabolic rate. By the age of 70 years olds, approximately 30% of our central rods have dies and our cones have reduced functionality. Recently use of 670 nm red light has been clinically proven to counteract this age-related vision loss. The improvement is only seen in older adults age 40 years old and older. The use of Red Light Therapy (RLT) to treat eye and vision-related issues is nothing new. …

Been waiting to try out Red Light Therapy, here are a few low-cost products to get you started.


You don’t have to spend a bundle of money to try Red Light Therapy (RLT). Amazon sells a few low-cost low-power LED light devices that are suitable for RLT. Because of their low-power, you use these devices a bit differently than high power RLT panels. The how and why of using these devices are discussed later. First I want to review the devices I purchased and their measured power output.

API 12 Watt 660 nm LED Bulb

This LED light is available on Amazon. It supplies a single 660 nm wavelength of light. …

If so, it may be time to reset and reboot for success.

By the end of February, millions of people who in January resolved a positive change for themselves in the new year have already given up. Most will blame their lack of willpower. But is that the reason?

Willpower Isn’t the Solution

The brute force approach will fail more than 90 percent of the time. Willpower is finite, and you can use it up just getting yourself to work on time every day, let alone succeeding at a new resolution goal.

If you’ve given up on giving up, maybe it’s time to reset and reboot your New Years’ resolution for success.

Specify Your Resolution
