You will be unable to sleep
This is the most obvious reason why you should never use your phone in bed. You will never be able to sleep because of all the notifications that are disrupting and disturbing your sleep. Of course, you know that doctors recommend at least 8 hours of sleep daily. Your phone should be on silent if you really want to get a smooth and uninterrupted nap.
You can be depressed
Persons who use their phone more frequently are prone to moodiness and depression. Also, since you are unable to get proper sleep just because you cannot control your phone usage, you are simply making you vulnerable to depression.
You are damaging your eyes
Exposure to blue light at night, emitted by your phone can affect the eyes. And today, there are many smartphones that emit this light. To prevent dry eyes and blurred vision, allow your eyes to rest instead of surfing your phone.
You may experience nomophobia
Imagine waking up in the middle of the night and you are searching desperately for your phone which is just right beside you. And because you cannot find it, you begin to feel anxious and you become agitated. The only time you recover is when you eventually find your phone. It's better to switch it off (if you want) and keep it as far away from you as possible.
Reduce exposure to radiation
Smartphones usually release a form of non-ionizing electromagnetic radiation that can be absorbed if it is too near your body. The risk is limited when the phone is disconnected from either WiFi or turned off.
You pay more attention to your loved one
There is no gainsaying that you will concentrate and listen more if you do away with your phone in bed. So, make that decision to limit phone usage in bed at night.
