New Delhi. Mobile has become such a part of our lives today that it is not easy to stay away from it. Be it looking at the phone as soon as you open your eyes in the morning or scrolling through social media just before sleeping at night, screens have become a part of our daily habits. Many people check notifications again and again while working, while some people go to reels videos and social media as soon as they get free time. The question is not only about how much of our time the mobile is taking, but now there is also increasing concern about how its continuous use is affecting our sleep, attention and brain function.
Recent research has found many important indications regarding mobile and screen time. A large systematic analysis included data from 21 studies and about 5.48 lakh people. In this, excess screen time was found to be related to less sleep, symptoms of insomnia, late sleep and difficulty in sleeping. According to the analysis, with every additional hour of screen time, sleep time can be pushed forward by about 13 minutes on average.
The problem of using mobile at night is not limited to screen light only. Constant notifications on the phone, social media posts, videos and messages keep the mind active. In such a situation, the person is not able to reach a state of mental rest even after going to bed. The result is that falling asleep may take longer and the quality of sleep may be affected.
A study published in 2026 looked at the impact of mobile phone use before bed on university students. Research found that people who used smartphones for a long time before sleeping were more likely to have poor sleep. The study also linked prolonged use of mobile phones to decreased concentration and some performance-related parameters and increased reaction time. However, the researchers also clarified that further larger studies are needed to apply these findings to a broader population.
The most important thing here is to understand that it would not be scientifically correct to say that mobile is directly spoiling our brain. The real problem often lies in the habits formed due to mobile use. If a person uses the phone late at night and is not able to get enough sleep, then the next day he may feel tired, irritable, have difficulty concentrating and reduced ability to work. If poor sleep persists for a long time, it can affect mental and physical health.
Another 2026 study looked at the relationship between social media and smartphone use before bed among adults. It found that high smartphone dependence and phone use in bed were associated with poor sleep, while there was also an association between poor sleep and difficulties in controlling certain executive abilities, such as working memory and attention. However, this study also does not completely prove the cause and effect.
In such a situation, leaving the mobile is not the solution but it is more important to change the way of use. Stepping away from your phone, especially before bed, can be an easy step to take. Reducing screen time at night, turning off notifications, and keeping your phone away from bed can be helpful habits. The habit of repeatedly looking at the phone unnecessarily even during the day can be reduced.
Mobile is a technology that makes our lives easier, but when this technology starts dominating our sleep and daily concentration, then we need to be careful. Currently, scientific evidence does not suggest that mobile phones are directly changing our brains in a permanent way, but continued, and especially excessive, use at night can affect sleep and related mental performance. Therefore, the question is not about giving up the mobile but about deciding whether the mobile is running us or we are running the mobile.
