In our daily lives, mobile phones have become our inseparable companions. However, there is a common concern that leaving our phones next to our pillows at night can expose us to radiation. So, is this statement true? Let’s explore it together.
Sources of cell phone radiation
The radiation emitted by a mobile phone mainly comes from its antenna, and this radiation exists in the form of radio frequency (RF) waves. This energy lies between radio waves and microwaves on the electromagnetic spectrum and is non-ionizing radiation. Non-ionizing radiation has low energy and is not powerful enough to directly damage DNA within cells.
Effects of mobile phone radiation on health
Although the radiation energy emitted by mobile phones is relatively low, long-term exposure may still have an impact on our health. The human body does absorb energy from devices that emit radio frequency radiation. However, the only widely recognized biological effect of radio frequency radiation on the human body is the heating effect. For example, the temperature of the hands and head may increase when a mobile phone is used. However, this heating is not enough to significantly increase core body temperature.
The relationship between mobile phone radiation and sleep
Studies have shown that exposure to cell phone radiation at night may reduce the amount of REM sleep, leading to impaired cognitive function and reduced daytime alertness. Additionally, notifications, reminders, and phone calls from your phone may interrupt your sleep.
How to reduce radiation exposure
There are some things you can do to reduce your radiation exposure. For example, you can keep your phone at least three feet away from your bed. If you need to use your phone as an alarm clock, you can turn on Airplane Mode to prevent your phone from sending or receiving calls and text messages while you sleep.
Conclusion
While cell phones do emit radiation, the energy of this radiation is low and not enough to directly damage our DNA. However, in order to ensure good sleep quality, we still recommend that you place your phone far away from the bed or turn on airplane mode while sleeping. In this way, you can protect your health while enjoying the convenience brought by technology.
