Cell phones have become an almost unavoidable part of daily life. We use them to stay connected to our friends and family, find tasty new restaurants or interesting places to hang out, and even to work. The National Cancer Institute estimates that there are more than 5 billion cell phone users around the world. However, did you know that your phone emits radiofrequency waves that may be detrimental to your health?
Non-ionizing radiation can be emitted from microwaves, radio waves, and cell phones. Although these everyday devices may seem benign, new research is showing that this radiation may be more damaging than we previously thought.
A 2017 study investigated the association between radiation exposure and thyroid dysfunction among people who used cell phones. The study measured thyroid swelling and daily length of phone usage of students at a medical college in South India. The researchers found a significant correlation between total radiation exposure and an unwanted increase in thyroid-stimulating hormone (TSH). The more the participants used their phones, the more TSH increased in their bodies.
This study emphasized a startling fact: we do not really understand the true impact of cell phone radiation on the body. Until more studies are conducted on the damaging impact of cell phone radiation, play it safe and leave the cell phone at home the next time you go for a walk or leave the house! Also, avoid sleeping with a cell phone within 10 feet of your head. You may find that you have better quality sleep.
