Smartphone Overuse Harms Nervous System, Sleep and Mental Health

Excessive screen time and constant digital stimulation keep the nervous system in a state of heightened alert, leading to mental fatigue, difficulty focusing, irritability and physical tension. Experts note that bright screens, endless scrolling and frequent notifications trigger stress responses that make it harder to relax and obtain restorative sleep. Studies cited by health professionals link heavy smartphone use to higher rates of anxiety, depression, poor sleep quality and reduced attention span, especially among adolescents and young adults.

In India, individuals such as entrepreneur Seema Goyal and textile maker Salma Zahoor report feeling drained and are turning to "dumb" phones to reclaim peace. Counselors and researchers observe that the dopamine spikes from app notifications reinforce compulsive checking, while reducing phone use can improve mood, sleep and overall well‑being within weeks.
