As much as you may like it to be, seeing isn’t always believing. In fact, more often than not, your eyes are almost constantly playing tricks on you. This is precisely why optical illusions are so fascinating.

A prime example of this is the infamous “dress” that went viral earlier this year. Online users — and even the First Lady — engaged in heated debates over the true color of the dress, which was black and blue. However, due to a literal trick of the light, the dress appeared white and gold to many frustrated viewers who swore what their eyes saw was indeed correct. #sorrynotsorry

Often times, it’s what the human eye doesn’t or is incapable of seeing that can be the most intriguing (and the most problematic). Examples of powerful forces and organisms unseen to the human eye include single-celled organisms such as bacteria, viruses, and pathogens, matter such as atoms and their even smaller components, gravity, and of course electromagnetic frequencies (EMF) and radiation emitted by various devices.

Though considered safe by many government agencies and based on countless research studies, it is still a good idea to protect children from EMF and anyone else who may be sensitive to its frequencies. Being that humans are highly electrical beings, EMF frequencies and radiation can easily cause bio-disruptions in the human body in the form of shorten attention spans, feelings of restlessness, headaches, and possibly even tumor growth.

Luckily, there are several ways to block EMF and radiation emitted from common household devices such as laptops, mobile phones, and others. This is where EMF shields come into play. EMF fields are just one of many of EMF protection. EMF shields are especially necessary for those with electromagnetic sensitivity, such as children, empaths, and those who are very energy sensitive.

In today’s modern world, people are almost constantly “plugged into” one device or another, whether it’s a smartphone, a tablet, a laptop, a desktop, or some other kind of digital device. In fact, these devices have changed so much about the way people work, play, and even date. However, too much of a good thing is never a good thing, and constantly being connected to these devices delivers pretty heavy hits of EMF and radiation.

Though further clinical research is still necessary to understand the exact long term consequences of long term exposure to EMF, many studies have already found some conclusive evidence of adverse effects. As such, now is the perfect time to invest in EMF shields for your personal protection as well as to protect those closest to you.
