Sleeping Near Your Phone Could Pose Hidden Health Risks, Expert Warns
A leading anesthesiologist has raised concerns about the habit of sleeping with a phone close to the head. Dr. Myro Figura highlighted potential health risks linked to mobile phone radiation, though no definitive proof of harm exists. The advice follows years of research into the possible effects of long-term exposure.
In 2011, the World Health Organization's cancer research agency classified radiofrequency electromagnetic fields as possibly carcinogenic. This decision came after limited evidence suggested a higher risk of glioma—a type of brain cancer—in heavy mobile phone users. Since then, further studies have explored the issue, including a review by Miller et al. of 13 post-2011 investigations. These found increased risks not only for brain cancer but also for tumours in the breast, testes, thyroid, and cases of leukaemia.
Animal research has added to the debate. The US National Toxicology Program and Italy's Ramazzini Institute both reported brain and heart tumours in rats exposed to 1.8 GHz frequencies—similar to those used by mobile phones. A 2015 study also suggested that radiation levels below current safety limits could still promote tumour growth.
Despite these findings, Dr. Figura notes that mobile phones emit non-ionizing radiation, which lacks the energy to break chemical bonds or directly damage DNA. This type of radiation is also present in sunlight and some medical imaging. Yet, the long-term effects on human health remain unclear.
To reduce potential risks, Dr. Figura recommends keeping phones away from the head while sleeping. Using a headset or speakerphone for calls is another suggested precaution.
The WHO's classification and ongoing studies have not provided conclusive evidence that mobile phones cause cancer. However, Dr. Figura's advice reflects a cautious approach to minimising exposure. For now, simple measures like increasing distance from devices at night may offer peace of mind while research continues.
