In today’s digital age, many of us rely on our smartphones for various tasks, even while we sleep. Whether it’s charging overnight or serving as an alarm clock, our phones often find their way onto our bedside tables and even our beds. However, a common concern that has surfaced is whether sleeping near a charging phone poses any health risks, including the possibility of causing cancer. Let’s delve into this topic and separate fact from fiction.

Does Sleeping Next to Your Phone Raise Cancer Risk?

Cell phones do emit radiation, and radiation does have the potential to increase cancer risk. But the radiation that comes out of your phone isn’t thought to be harmful to your health.

Ionizing radiation, which is sent out from X-rays and radon, can cause damage to DNA that may increase a person’s chances for cancer. But the radiation emitted from cell phones, called radiofrequency radiation, is nonionizing, meaning it does not cause DNA damage, according to the National Cancer Institute (NCI).  For the record, it’s not the only source in your day to day; radiofrequency radiation is emitted by radio and TV signals, microwaves and Wi-Fi, to name a few, per the NCI.

“Large meta-analyses have been done to look for any support that there’s a relationship between cell phones and cancer, but none have been able to make a strong claim,” says Stephanie Weiss, MD, Chief, Division of Neurologic Oncology at Fox Chase Cancer Center in Philadelphia. “As of now, we do not have any reason to believe cell phones cause cancer.”

That being said, it’s essential to exercise caution and practice good sleep hygiene when it comes to using electronic devices in the bedroom. While the radiofrequency radiation emitted by charging phones are generally considered safe, excessive screen time before bed can disrupt sleep patterns and interfere with the body’s natural circadian rhythm. The blue light emitted by screens can suppress the production of melatonin, a hormone that regulates sleep-wake cycles, making it harder to fall asleep and potentially leading to sleep disturbances.

A sudden beep, buzz or other sound emanating from your cell phone is sufficient to awaken you from sleep.

To promote better sleep quality, experts recommend establishing a bedtime routine that does not involve screen time at least an hour before bed. This can include activities such as reading a book, practicing relaxation techniques, or engaging in light stretching exercises. Additionally, consider keeping electronic devices, including charging phones, at a distance from your bed to minimize potential disruptions to sleep.

In conclusion, there is no scientific evidence to suggest that sleeping near a charging phone poses any health risks, including cancer. While it’s essential to practice good sleep hygiene and limit screen time before bed, there is no need to fear the radiofrequency radiation emitted by smartphones. By adopting healthy sleep habits and maintaining a balanced approach to technology use, you can enjoy restful nights without unnecessary worry.
