Ivory Tower Excessive internet-use linked to poor sleep among medical students, says study

Across-sectional study, conducted across multiple medical institutions in India, revealed a worrying association between excessive internet usage and poor sleep quality among undergraduate medical students. The research applied the Pittsburgh Sleep Quality Index (PSQI) and the Internet Addiction Test (IAT) to assess lifestyle patterns and their impact on health. Medical institutions from across the county, including, Christian Medical College (CMC), Ludhiana, took part in the study.

Key findings

Students with moderate to severe internet addiction recorded a mean PSQI score of 6.76 ± 2.45, indicating poor sleep quality.

Those with mild addiction showed a slightly lower mean score of 6.58 ± 2.57, but still within the poor sleep range.

The study found that 22.45 per cent students with higher internet addiction reported poor sleep quality, a statistically significant correlation (P < 0.01).

Average IAT scores of 39.93 ± 10.36 were directly linked to deteriorating sleep quality. Excessive internet use was associated with poor sleep scores (11.04 ± 1.99), again statistically significant (P < 0.05).

Expert perspectives

Dr Anjali Mehta, a clinical psychiatrist, explained, “Medical students are under immense academic pressure and the internet often becomes both a coping mechanism and a distraction. Unfortunately, prolonged screen time interferes with circadian rhythms, leading to poor sleep quality and fatigue.”

Another expert from CMC added: “Sleep deprivation among young adults is not just about feeling tired. It has long-term consequences—ranging from impaired concentration and memory to increased risk of anxiety and depression. This study highlights the urgent need for awareness and interventions.”

Public health concern

The findings underscore that internet addiction is not merely a lifestyle issue but an emerging public health concern. Poor sleep quality among medical students—future healthcare providers—raises alarms about their well-being and professional readiness.

Recommendations

Experts suggest that students should limit late-night internet use and avoid screens before bedtime. Engage in sports, cultural activities and social interactions to balance academic stress. Practice digital hygiene, such as scheduled offline hours. Seek counselling if internet use begins to interfere with daily functioning.

“Healthy living requires balance. While the internet is indispensable for education and communication, moderation is key. Encouraging students to participate in physical, cultural and social activities can help restore that balance,” added Dr Mehta.
