Exposure


Exposure, Sleep-Research

The amount of time spent using screens is a key factor in understanding the impact of screen time on sleep. Studies have shown that even short periods of screen time can have a negative impact on sleep, and that the more time spent using screens, the greater the risk of sleep problems.

  • Facet 1: Total screen time

    Total screen time refers to the total amount of time spent using screens per day. Studies have shown that adults who spend more than two hours per day using screens are more likely to have trouble falling asleep, staying asleep, and waking up feeling tired.

  • Facet 2: Time of day

    The time of day when screens are used can also affect sleep. Studies have shown that using screens in the hours leading up to bedtime can make it more difficult to fall asleep. This is because the blue light emitted from screens can suppress the production of melatonin, a hormone that helps us to sleep.

  • Facet 3: Content

    The type of content that is viewed on screens can also affect sleep. Studies have shown that watching violent or disturbing content can lead to nightmares and difficulty sleeping.

  • Facet 4: Device

    The type of device that is used can also affect sleep. Studies have shown that using a laptop or tablet in bed can make it more difficult to fall asleep than using a phone or e-reader.

By understanding the different facets of exposure to screen time, we can better understand the impact of screen time on our sleep and take steps to reduce our risk of sleep problems.

Timing
