Is Sleeping Next To Your Phone Dangerous?

Ever since the concept of wireless phones came into existence, folks have been trying to find if they can be harmful to human body. Nowadays, many people use their phone before sleeping and most of them keep their phones next to their head or under the pillow while they sleep. If you have are one of the people and you have been wondering if it can be dangerous to your health, the short answer is no. No research has thoroughly proven that sleeping next to a phone can cause cancer or any other damage to human body.

Is Sleeping Next To Your Phone Dangerous?

Here is a details answer to the question that Toxicologist Renee Hartsook answered on Quora:

First, let’s understand the facts about mobile devices and this perception of risk of harm:

  • The type of energy emitted from mobile devices is radiofrequency and it does not have the ability to damage to DNA like ionizing radiation (such as an x-ray).
  • Several large epidemiology studies were conducted on mobile phone use and the risk of central nervous system cancers. The studies do not establish an association between mobile device use and the risk of central nervous system cancers.
  • The International Agency for Research on Cancer (IARC), part of the World Health Organization, is the predominant public health authority on identifying and labeling carcinogens as such. Their working group concluded that it was possible that radiofrequency exposure from mobile devices is associated with cancer risk.

However, all of US health agencies (Centers for Disease Control, Food and Drug Administration, and National Institute of Environmental Health Sciences) make strong statements for mobile device safety and find no link between radiofrequency energy and cancer risk.

The National Cancer Institute has created a great fact sheet on this topic.

Bottom line: As a toxicologist do I believe that there is a risk? No.

That said, common sense is a good thing. I would not advocate sleeping with your phone next to your head, primarily because you will benefit from uninterrupted sleep.
