mobile phones, usage hours, sleep pattern


The widespread use of mobile phones has become integral to the lives of medical students, providing constant connectivity and access to information. However, this constant use poses significant concerns regarding its impact on sleep patterns, which are crucial for maintaining health and cognitive function. Which will intern affect both the student and patients.

Aim of study: This research investigates the extent to which mobile phone usage affects the sleep quality of medical students, with a particular focus on the Indian context. By understanding these dynamics, we aim to develop targeted interventions to promote healthier sleep habits and improve the well-being and academic performance of future healthcare professionals.

Material and methods; Totally 1155 medical students ( male 498 and female 657)

from various medical colleges in Coimbatore were taken for study between September  2023 to Dec2023 after getting informed consent , a questioner given Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality and duration and evaluated

Results :of the 1155  students, the more mobile phone  time adversely affects the sleep score so that it is proved that usage of mobile phones  definitely affects the sleep quality , concentration, cognizant behavior of the students

Conclusion: excessive screen time, particularly before bedtime, can negatively affect sleep. The blue light emitted by screens can interfere with the production of melatonin, a hormone that regulates sleep-wake cycles. Additionally, engaging with stimulating content on mobile phones, such as social media or academic materials, can increase cognitive and emotional arousal, making it more difficult to fall asleep
