Question 29

Pre-Sleep Screen Habits

Sleep quality is heavily influenced by bedtime routines, particularly the use of digital devices. To investigate this, a researcher used a questionnaire to find out which primary screen activity participants aged 18–25 and aged 50–67 engage in during the 30 minutes immediately before trying to sleep. Below is a table displaying the data collected from 300 individuals who participated in the study.
