School TV: Technology and Sleep

Technology and sleep factsheet

Recent studies suggest that sleep is indeed affected by technology use in the hour before bed.

Late-night technology users reported having a less satisfactory sleep more often than those not using technology before bed. These users are also more likely to feel sleepier during the day in a range of situations, including driving.

These findings relate to both using a computer or laptop before bed or texting on a smartphone. Repeated use of a bright screen over 5 days can delay the body clock by 1.5 hours. This means you consistently want to go to bed later and sleep in longer. This can be a real problem when you need to get up at a set time in the morning for school or work.
