Limit blue light exposure at night for improved sleep

Taking steps to limit blue light exposure in the hours leading up to bed can increase your chances of falling asleep and getting high quality Z’s. 

  • Light exposure regulatest the wake-sleep cycle and impacts your Circadian rhythm. 

  • Exposure to blue light at night inhibits the release of melatonin, a hormone that helps you fall asleep, and can negatively impact your sleep. 

  • Blue light exposure has been linked to increased sleep onset latency, meaning it takes longer for individuals to fall asleep.

  • Indoor lighting and electronic devices emit substantial blue light, intensifying the struggle for a good night's sleep.

  • Reduced melatonin levels contribute to fragmented sleep and increased wakefulness during the night.

  • Keep your devices out of your bedroom so you’re less likely to look at them before you go to bed. 

  • Limit your screen time for 2-3 hours before you go to bed. 

  • Dim the lights after dusk. 

  • Wear blue light blocking glasses.
