The ancient practice of cupping is back but does it work for pain relief?

© AP
There has been a great deal of media buzz about the purple dots on Michael Phelps' back and shoulders at the Rio Olympics. The Canadian broadcaster CBC focussed on it both on their web page and on Mark Tewksbury's commentary on TV. Both provided interesting discussions, but both concluded that there is no evidence or that "Some experts are skeptical of the treatments effectiveness."

Though there may be little evidence specifically of muscle recovery, there is plenty of evidence of benefit for the type of musculoskeletal pain that athletes can experience.

Wearing blue-blocking glasses can improve your sleep and protect your body's internal rhythm

You may remember the blue-blocking sunglasses that were popular in the U.S. in the 1980s. The glasses, with their amber-colored lenses, had a bit of a cult following and were perhaps best known for how clear they made regular objects appear.

They were promoted by Joel Sugarman who is actually a friend of mine and regular reader of this newsletter.

However, many are not aware that these glasses were originally designed for the NASA space program. Astronauts need powerful eye protection in outer space, where ultraviolet (UV) rays from the sun are incredibly strong.

A sunglass manufacturer developed a special design that blocked not only the UV rays but also blue rays.1 The glasses had the desirable "side effect" of making objects appear sharper, but the real benefits of blocking blue light are only beginning to be understood.

Far beyond the benefits to your visual clarity, blocking blue light serves an important biological purpose, helping to regulate your internal clock to control sleep patterns and other body functions. Quite simply, avoiding blue light at night is crucial to protecting your health.

Why Exposure to Artificial Blue Light Needs to Be Avoided

Exposure to artificial light is one of the largest often-overlooked health risks of living in the 21st century. Your early ancestors had no such worries, as their day started and ended with the rise and fall of the sun, which synchronized perfectly with their circadian rhythm.

Today, your body is still attuned to this internal clock. In the morning, bright, blue-light-rich sunlight signals to your body that it's time to wake up. At night, as the sun sets, darkness should signal to your body that it's time to sleep.

The problem is that most people living in developed countries no longer go to sleep when the sun sets.

Simple scratch and sniff test can be used to predict Alzheimer's Disease

Introduction:

The ability to correctly identify odors may prove to be a more functional approach to identifying people at risk for early stages of Alzheimer's disease (AD). Currently, physicians have to rely on expensive medical imaging (CT, MRI, or PET scans) to look for changes in the brain that are characteristic of AD. However, one of the problems with brain imaging beyond their cost is that it simply like taking a picture of the brain. Although sometimes these pictures provide valuable information, they do not evaluate the actual function of the brain.

Research has suggested that simple smell tests evaluating a person's ability to identify odors may prove to be a practical screening tool for AD and age-related mental decline. Now a new study from Columbia University researchers has shown that a simple, inexpensive scratch and sniff test was shown to be better than an MRI measurement in predicting the early stages of AD.

No surprise: Infertility-causing chemicals found in humans are also found in dogs

The same chemicals that disrupt sperm quality in humans are also being discovered in a range of commercially available dog foods--including brands specifically marketed for puppies. Sperm quality in dogs has fallen rapidly over the past three decades, a trend which could help explain the purported decline in human fertility.

Researchers at the University of Nottingham believe that the study could help explain the reported significant decline in human semen quality.

The work, published in Scientific Reports, highlights a potential link to environmental contaminants, after they were able to demonstrate that chemicals found in the sperm and testes of adult dogs-- and in some commercially available pet foods -- had a detrimental effect on sperm function at the concentrations detected.

Why you don't want to be Vitamin E deficient

Vitamin E is an important fat-soluble vitamin and antioxidant that helps combat damaging free radicals. It also plays a role in the making of red blood cells and helps your body use vitamin K, the latter of which is important for heart health.1

Unfortunately, estimates suggest about 6 billion people worldwide are deficient in this basic micronutrient.

According to a recent review presented at the World Congress of Public Health Nutrition, more than 90 percent of Americans fail to reach the recommended daily allowance (RDA) of vitamin E.2

An earlier review3 published in 2012 found that over 75 percent of Americans and Britons failed to meet minimum RDA levels for vitamin E. The RDA for people over the age of 14 is 15 milligrams (mg) of vitamin E per day, but most Americans get only half that amount.4

Is your urine Roundup ready? The majority of tests come back positive

According to urine tests taken in the European Union rather recently, 48 members of the EU Parliament volunteered to have their urine tested and ALL tests came back positive! [1]

According to the article titled "We are pissed off" [1],
The Biocheck lab in Leipzig that carried out the 'Elisa test' concluded: "All participants excreted glyphosate by urine. This means that glyphosate could be also a health problem of EU-parliament members." [....}

On average, the MEPs had 1.7 micrograms/litre of glyphosate in their urine, 17 times higher than the European drinking water norm (0.1 microgram/litre). This means that everyone we tested was way above the limit for residues of pesticides in drinking water.

Additionally, No less than 99.6% of all citizens who took part in this survey had higher residue levels. This means that virtually all citizens are contaminated with glyphosate. [....]

Sunlight avoidance correlates with a global rise in cancers


Fearful beachgoers in China are trading their suncreen and hats for facekinis.
A causative link between the sun and cancer does not exist and never has. The cancer and sunscreen industries have made it their mission to convince the world that sunlight is a primary cause of skin cancer, when in fact it has been shown to prevent it and many other forms of cancer.

It is a common sight these days to come across girls riding their two-wheelers and scooties, all covered up to avoid the sun's rays on their person. They even wrap a stole around their faces, such that not an inch of their face is seen, and wear gloves to keep the sun away from their skin.

Experts say that despite living in a tropical climate, it is unfortunate that many don't expose themselves to the sun to get the RDA (recommended daily allowance) of vitamin D.

Men are significantly weaker than they were 30 years ago, says new study

Think you'd beat your dad in an arm wrestling competition when he was your age? Bad news: he'd probably kick your ass.

Men today are weaker than they were 30 years ago, research in the Journal of Hand Therapy found.

In the study, men aged 20-34 have lower grip and pinch strength - which measures how strong your hand and upper extremities are - than the same aged guys did three decades ago.

In fact, the average grip strength for men ages 25-29 is nearly 12 kilograms lower today than it was before.

Your grip may not seem super important unless you're a competitive arm wrestler, but it actually serves as a good proxy of your overall strength.

Epigenetics: The keeper of the code

© Unknown
When it comes to DNA, the way it is packaged is as important as the code.
In recent years, attention has increasingly turned away from DNA's code and toward the way that DNA is packaged and the proteins that interact with it. These so-called epigenetic factors are heritable, reversible, and hugely influential.

Over the last few decades, epigenetics has become a hot scientific topic.

With potential roles in cancer, neuropsychiatric disorders, and immune disorders, it is no surprise that epigenetics is garnering such intense attention.

The way in which genes are expressed is incredibly complex; it requires the infinitely detailed coordination of multiple molecular players.

Epigenetics creates an additional layer of complexity that researchers are only now beginning to understand.
