Mobile phones are electronic devices that emit electromagnetic waves and heat at high frequencies. According to the World Health Organization (WHO), electronic devices in general can be harmful to the body and increase the risk of cancer if used for too long. In particular, placing a mobile phone next to you while sleeping is even more harmful than using it normally.
Placing your phone next to you while sleeping can directly impact sleep quality.
Health effects
Smartphones communicate by transmitting radio waves through a network of antennas. These radio waves are also known as radio frequency waves. In 2014, the International Agency for Research on Cancer (IARC) classified the electromagnetic fields emitted from smartphones as "possibly carcinogenic to humans."
However, shortly afterward, this organization found no increased risk of head or neck cancer for people who had used smartphones for more than 10 years. Numerous other studies have yielded similar results. Another reputable organization, the American Cancer Society, also acknowledges that this remains a difficult issue to clarify.
Many people believe that placing a phone near your body while sleeping can cause cancer.
In 2018, a research team in the US also showed that the risk of developing rare heart tumors increased in male mice when the animals were continuously exposed to electromagnetic fields, but not in female mice. The study also reported an increased risk of certain types of tumors in the brain and adrenal glands.
To date, the harmful effects of sleeping next to a smartphone on the body are still not fully understood. Furthermore, most of us not only keep our phones near our beds but also carry them in our pockets or hands throughout the day. Any health risk could arise from sleeping near a phone for varying lengths of time.
Interrupting sleep
Many experts have warned that using phones before bed is not good because it directly impacts sleep quality. The bright screen and stimulating mobile signals can disrupt our sleep cycle and even make it difficult for the brain to enter a state of rest.
Using your phone before bed directly affects the quality of sleep for many people.
Most people wake up a few times during the night. At these times, the first thing you want to do is grab your phone for a little entertainment before going back to sleep. However, this won't help you fall back asleep quickly; on the contrary, it will only make it harder to fall asleep.
Because the light from your phone signals to your brain and body that your sleep time is over. This is something no one wants to experience. Keeping your phone out of reach can help resist this temptation. Therefore, stay away from your phone if you accidentally wake up in the middle of the night.
