Malicious Scientific Miscommunication

As you probably have seen in malls or in online ads, there have been a recent surge in products known as “energy bracelets”. Examples you may have heard include “negative ion” bracelets or “hologram bracelets”.

You have probably also heard that these bracelets can improve balance, treat disease, and perhaps even save the world. Skeptical, you might ask the salesperson why or how these bracelets would help you. They would then give you a whole lot of scientific jargon and explain why each piece of false evidence is true.

If you were to look at a typical bracelet website, such as  Energy Force,  you would find that they make numerous claims such as

“ENERGY FORCE…regulates your body’s frequency to an ideal level. Optimal health and peak performance occur when your body maintains ionic balance (the exchange between negative and positive charges) and free flowing energy pathways (harmony) at the optimum frequency.”

How does this bracelet maintain balance? Why does ionic balance matter for health? How does it help you stay healthy? Why is it good to have the “optimal frequency”?

In reality, you wouldn’t find any answers to these questions, because these claims are not scientifically proven.

However, there are some much more devious scams that try to trick you in much less obvious ways. They do this by manipulating scientific data in order to make it fit their claims.

Some examples of the claims made by EQbandz

1. “Anti-oxidising: US Dept. of Agriculture found that anions led to 52% less dust in the air and 95% less bacteria“
2. “Emotional: 25 people tested with seasonal affective depression (SAD) found that anion treatment proved to be as effective against SAD as antidepressants without the side effects of these drugs”
3. “Immune system: Norwich Union Insurance Group: Reduced incidence of sickness and headaches by 78% when exposed to 1000 anions per C/C.”
4. “Aging: Dr Nagao Katsharu, Japan found that skin cells were replaced at 2.5 times normal speed with anions by accelerating the delivery of oxygen to the cells and tissues.”

These claims sound like the band is 100% scientifically proven to work! However, if one was to track these down, they would find that  these claims reference studies that were done using gigantic air-ionizer fans, which are much more powerful than a small bracelet. Interestingly a simple Google search reveals that the “doctor” in claim 4 does not seem to even exist. There are much more problems with these claims, and they can be found here.

katatrepsis has this to say:

[The companies are basically saying] “look at all this good stuff air ionisers do, here’s a bracelet that does the same thing” [which] is like saying “look how great scuba equipment is for breathing underwater, here’s a paper bag filled with air”

The conclusions that can be made from research have to be very carefully constructed. By taking legitimate research and formed their own unscientific conclusions, these companies can maliciously miscommunicate the studies to trick potential consumers.

As students in a science communication class, we have a duty to be able to identify these miscommunications and set them straight for the public, as katatrepsis does.

Sleep Quantity VS. Sleep Quality!

Does sleeping longer really benefit us throughout the day? Most of us have been told that lots of sleep is necessary to function at our best, but there really haven’t been any findings that show more than 7 or 8 hours of sleep causes you to function well or to function even better than normal compared to sleeping 6 or 7 hours. Not many  people realize the importance of the amount of time that is actually needed for the brain to refresh itself and the habit of sleeping at the right time along with waking up at the right time.  I argue that sleeping longer does not improve cognitive and body functions, but sleeping with a consistent schedule and good sleep quality is better for the body and brain.

Sleep quantity is important, especially in the time the brain needs to refresh itself through different stages. Sleep can be characterized into four stages and rapid eye movement (REM). The first stage is where the body is in between consciousness and unconsciousness and theta activity is between 3.5 and 7.5 Hz. The second stage is where eye movement ceases, and brain waves slow down. The third stage is when the brain starts producing delta waves. By the fourth stage, the brain pretty much just produces delta waves exclusively.

After the fourth stage, the body is now in REM sleep, usually referred to as deep sleep. During REM sleep, breathing becomes more rapid and the eyes jerk rapidly in different directions. It is also during this time that the quantity of sleep is very important because the brain and body is rejuvenating itself. But is it wise to think that, because brain and body need lots of time to rejuvenate itself, oversleeping is justified?

According to the American Sleep Association (ASA), the average amount of sleep for adults usually fall in the range of 7.5 to 8.2 hours of sleep; however, there are variations where others may need as little as 5 or 6 hours to function just as well.

Mercy Medical Group neurologist and sleep specialist Alan Shatzel shares that efficient and quality sleep is very important, and the reason why people are sleep deprived even when they do sleep some 8 hours is because there are various factors that are interfering with their sleep.

An article from the Journal of Psychosomatic Research looked at the sleep quality vs. the sleep quantity between college students. What the study showed was that sleep quality was better related to health, feelings of tension, anger, anger, fatigue, and confusion. This study not only shows that sleep quality is more important than sleep quantity, it also shows that sleep quality with a consistent schedule is necessary for better performance.

From my own experience, university is tough and in order to do well, there are times when I have skipped several nights of sleep just to review more material. However, whether I did well or not, I would always feel very unsatisfied afterwards; not because of the test, but because I would be getting headaches and other pains. Even after sleeping for 10 hours just to make up for lost sleep, I would still feel horrible and tired.

Therefore, I would strongly advise everyone that whether you have an exam tomorrow or a big presentation in a few weeks, the best strategy for doing well is sleeping with  consistency (~7-8 hours per day) along with good quality sleep!
