If you care about your health, don’t leave your phone next to your bed at night!


According to the results of a survey, more than half of people go to bed with their smartphone in many cases. Among those who do not take their mobile phone with them while sleeping, many have declared that they put their smartphone on the table next to their bed.

Unfortunately, we have bad news for these people, because sleeping with a smartphone is very harmful to health. Whether you are an adult or a teenager, a lot of research has been done in this regard and the results of all of them are the same: sleeping with a cell phone is bad for your health.


Of course, we do not intend to give you an order in this article, but we will bring you the results of some of these researches so that in the end the final decision is yours.

If you have trouble falling asleep, suffer from insomnia, or can’t stay awake during the day, there is reliable information that shows that these problems are rooted in your cell phone.

What do the reviews say?

For example, a systematic review of the results of 20 studies shows that there is a direct relationship between sleeping problems, staying awake during the day and insomnia, and the proximity of electronic devices while sleeping. Using electronic devices or being close to them while sleeping has a direct negative effect on the quality and amount of sleep.

In other words, if you reached in bed and managed to take your smartphone, it is very likely that your sleep is not deep enough and you are not sleeping enough. Interestingly, these negative effects only increase with the presence of a mobile phone next to your bed, and it is not necessary to use it.

Sleep has a direct impact on our physical and mental health and is essential for children’s biological, psychological and social development. Since portable smart devices such as smartphones have become an integral part of our waking life, their impact on sleep quality is of great concern.

Many of us check our smartphone before going to sleep and the first thing we do after waking up is to check our mobile phone again. This destructive habit affects our sleep health and endangers our physical and mental health.

Serious injury to children

Meanwhile, the most destructive effect is on children; So that ten-year-old children lose eight to nine hours of sleep per week. The study conducted in this regard has a limited statistical population, but it is one of the few studies that has deeply researched the impact of networks such as Tik Tok and Instagram on students’ fear of falling asleep.

Now, children are not only socialized in schools, and social networks have brought this process to their beds as well. These networks are active 7 days a week and around the clock, and the activity of some of them increases especially in the middle of the night.


One of the disadvantages of lack of sleep is depression. A study conducted on a large number of teenagers shows that teenagers who spend more time on social networks suffer more from lack of sleep, and as a result, they are more likely to suffer from severe depression.

Here we see a chain of cause and effect; Teenagers who spend the night spending time on social networks suffer from lack of sleep, and people who do not sleep enough are more likely to fall into the trap of depression. Lack of sleep can even affect the academic grades of these people.

Adults are also at risk

As we said, this effect is not limited to children and teenagers and it has destructive effects on adults as well. A study on people in their 40s shows that using a smartphone before going to bed makes them more tired and affects the duration of their sleep. For people in the age range of 60 years, these negative effects include waking up early and reducing the duration of sleep. Now that these issues and problems have been raised, what is the solution?

Considering these issues, some companies have taken the initiative to improve their use at night by adding some settings to their production smartphones. However, the research showed that the Night Shift function in iPhone phones has no positive effect on increasing the quality of sleep of 167 people participating in this research. Not using a smartphone increases sleep quality more than using it in Night Shift mode. According to this research, it can be concluded that features like this in Android phones, such as Bedtime Mode in Samsung phones, do not have much effect on improving the quality of sleep.

Dangerous psychological injuries are lurking!

But a question may arise here, why using a mobile phone before going to sleep brings such harm? To begin with, we must say that the blue light of the smartphone screen delays the release of the hormone melatonin in the body. Melatonin is the hormone that regulates the sleep and wake cycle in the body. Blue light filters can partially solve this problem; But still somewhat and not completely.

Another reason for the harm of using a smartphone before going to sleep is related to the way we interact with these devices. Today, mobile phone software and applications are designed in such a way that by attracting the user, they keep him in the software environment as much as possible, and in this way, they use all possible methods, including psychological games and creating mental attractions. The truth is, by the time your phone rings or even vibrates, chances are you’ll be checking it to make sure it’s nothing serious. This issue highlights the importance of smartphone notification management. In addition to this issue, the negative impact of smartphone radiation on the human body is also an issue that has been proven many times during various researches.

If you are worried after reading this article, maybe it’s time to give you some good news. Fortunately, all these harmful effects will be resolved with only one month away from the mobile phone while sleeping; That is, if you put your phone away from you while sleeping, a month later, your sleep quality will return to the desired level. Keeping the smartphone away from you during sleep for four weeks improves the quality of sleep, increases its duration, reduces arousal before sleep (high heart rate and inability to focus thoughts), increases positive emotions and improves cognitive memory performance.

What to do?

Getting enough sleep is one of the essentials for maintaining physical and mental health; And this is important depending on your management to work with your cell phone. If you are not satisfied with the quality of your sleep, giving up your smartphone at least two hours before bed can be the medicine you are looking for. Using features like Digital Wellbeing can help you manage your smartphone usage. You can set a daily limit for the use of some of your most used applications so that they do not disturb your sleep at the time you set. Finally, we must note that technology must be used to increase our well-being and health, otherwise it will not be very effective.
