Blue light emission
In addition to actually reducing the time spent sleeping, the mobile phone screen and the light it emits can severely affect your body, interfering with your body's natural circadian rhythm.
This causes a day/night confusion for the body and prevents your body from producing the chemicals that make you sleep well (as well as those that cause you to wake up).
In addition, the blue light that mobile phones emit has a stimulating effect on the body.
Using your phone before you go to sleep or even in the middle of the night has a detrimental effect on the quality of your sleep.
Potentially dangerous waves
The harmful effects of radiation from mobile phones have not yet been scientifically proven.
However, this matter has been the subject of lively debate for quite some time, and the talk of cancer and tumour prevails.
Even though there is not yet sufficient scientific evidence - and some of the effects of mobile phones may only appear in the long term - this still raises sufficient doubts about the safety of mobile phones.
Of course, this applies not only to sleeping.
Concerns have been raised about holding your phone up to your ear while speaking or keeping it in your pocket, and, indeed, it is wise to find alternatives to these.
At night, it is strongly advised to keep your mobile phone away from your bed while you're sleeping.
Experts recommend that mobile phones should be at least one metre away from our bodies when we sleep.
Even better, switch the phone off or put it into flight mode.
If you don't feel comfortable doing this, then at least turn off connections such as Bluetooth or Wi-Fi.
