In your pocket
Keeping your phone in your pocket seems logical, but you could be doing more harm than good. According to Dr Lilly Friedman, this is actually the worst place to store your phone. “When phones are on, connected to a wireless network, and placed in a pocket, the radiation is two to seven times higher than if it were placed in a purse or holster,” she says. There is a correlation between radiation from a mobile phone and tumour growth, she adds. Plus, radiation can change the structure of DNA and affect male fertility, according to Dr Friedman. The World Health Organization’s International Agency for Research on Cancer also found that mobile phone radiation is additionally carcinogenic to humans. Merely sitting on your phone could cause health issues such as sciatica or back problems.
In your bra
Some research and case studies show that keeping your phone in your bra could be linked to breast cancer due to the radiations and vibrations from the phone. That said, there is not enough evidence to establish a definite relationship between the two. Still, keeping your phone in your bra, especially a sports bra, is a bad idea due to the skin-irritating bacteria it could harbour, Muscle & Fitness reports.
In your bed or under your pillow
Sleeping with your phone is a bad idea for a few reasons. First, keeping your phone under your pillow could build up heat and present a potential fire hazard, especially if your phone is charging or has a defect. It’s also known that the LED light from phone screens can disrupt melatonin production and circadian rhythms, hurting your sleep quality, according to the National Sleep Foundation. And, of course, there’s also radiation to consider. The amounts of radio frequency radiation mobile phones give off are the same ones emitted from microwaves. There is also concern about the safety of mobile phone use with respect to cancer and brain tumours, per the American Cancer Society.
