A smartphone can have a negative impact on a person’s health, including their sleep. This was stated in his blog on WeChat by Master of Engineering Physics Shang Zhinan.
According to the expert, the smartphone is a source of radio magnetic radiation, but you should not be afraid of the device: “I often hear people say that the phone emits strong radiation and you can get cancer.” However, there is currently no evidence that radiation from a smartphone can cause malignant diseases, such as cancer.
How do phones affect sleep? – Jinan said that regulators set specific safety standards that gadget manufacturers are required to comply with. Therefore, the radiation coming from each certified smartphone is strictly regulated. The specialist described the standard of safe radiation in China — the average specific rate of absorption by biological tissue within six minutes should not exceed two watts per kilogram.
However, smartphones and other devices indirectly affect the health of the user. Jinan referred to the recommendations of scientists, according to which with regular refusal of gadgets for 30 minutes before bedtime, the quality of rest increases within four weeks. “Tonight — before going to bed — put your phone away”, – the specialist concluded.

At the end of 2020, the neurologist “SM-Clinic” Maria Ignatova explained the danger of sleeping next to the phone. According to Ignatova, all gadgets have radio frequency radiation, which is absorbed by the tissues of the human body and, as a result, negatively affects its health. At the same time, the expert stressed that there is no reliable data on the negative impact of smartphone radiation on the human body.
