Issues of the brain are not just limited to adults anymore. Teenagers and young adults today are sleeping less, scrolling more, and living under constant pressure of the modern faced-paced lifestyle. With screen times soaring past 7 hours a day and stress levels rising steadily post-pandemic, young minds are undergoing a silent but dangerous neurological shift. A recent WHO study reveals that globally, 1 in 7 adolescents aged 10-19 years experiences a mental disorder. In such a scenario, understanding how everyday habits are reshaping both psychological and physical health becomes necessary to prevent long-term damage to the body.
How are unhealthy habits rewiring young minds?
According to Dr Aparna Gupta, Associate Director- Neurology, Indian Spinal Injuries Centre, New Delhi, “The brain is still in the process of developing in the mid-20s. In fact, it is growing rapidly in this period and is highly sensitive to external influences.”
Talkin about potential reasons that causes brain rewiring in young kids, Dr Gupta shares, “Factors like early exposure to screens, sleep deprivation, and stress can disrupt this development in young adults, leading the brain to rewire itself instead of adapting to the changes brought about by the modern lifestyle. So, even simple, seemingly harmless habits can affect the brain negatively.”

How sleep deprivation can affect brain development?
Not sleeping enough or staying up till late at night has different implications for adults and younger populations. According to a study conducted by the University of North Carolina, youngsters are unable to catch up on sleep the way adults do. While sleep is linked to maintenance and repair functions in adults, it relates to cognitive development in young individuals. Lack of it can significantly impact memory and concentration. Without sleep, one cannot form or maintain the pathways that enable learning and creation of new memories.
The National Institute of Health has stated that more than 7 hours of digital screen time for kids is responsible for the thinning of the brain’s cortex. This impacts the critical thinking and reasoning skills of children and young adults. In addition, the brain’s reward system gets overstimulated which results in extremely short attention spans and messed up dopamine cycles. Emotional intelligence and social cognition also take a hit.

Academic pressure, uncertainty of the future, work-related stress, and insecurity caused by social media are some unique problems that are fuelling chronic stress among youngsters. While some amount of stress is healthy for the brain’s development, long-term stress can impact the hippocampus (responsible for learning and memory) and increase the likelihood of depression and anxiety. Stress has also been linked to various cardiovascular conditions.
What small changes can protect the brain from damage?
Tech-neck, tension headaches, and early onset cervical-disc issues are becoming increasingly common in young adults due to reasons like constant tech use and poor posture. Procedures such as a cervical decompression surgery, once mostly done in older adults, is now being seen in patients as young as their 20s.
While it is impossible to eliminate screens completely from daily routines, simple lifestyle shifts can go a long way in preserving brain function. Prioritising quality sleep, taking regular digital breaks, staying physically active, and practicing mindfulness are small but powerful habits that support brain health. In a hyperconnected world, these shifts offer a way to reset, protect, and strengthen the mind one day at a time.
