The Negative Effects of Technology on Sleep
Blue Light and Melatonin Suppression
Disrupts Circadian Rhythm
Blue light from screens delays melatonin production, making it harder to fall asleep.
Impacts Sleep Quality
Even short exposure before bed can reduce REM sleep, leading to less restorative rest.
Mental Stimulation and Sleep
Social Media Increases Alertness
Scrolling through stimulating content keeps the brain active, delaying sleep onset.
Work Emails Cause Stress
Checking emails late at night can increase anxiety, making it harder to relax.
Use Night Mode on Devices
Enable blue light filters in the evening to reduce melatonin disruption.
Set a Digital Curfew
Avoid screens at least 1 hour before bedtime to improve sleep quality.
Strategies to Reduce Tech’s Impact on Sleep
Optimize Your Bedroom for Sleep
Keep Devices Out of the Bedroom
Charge phones outside the bedroom to avoid temptation.
Use an Alarm Clock Instead of Your Phone
A traditional alarm clock eliminates the need for a phone by your bed.
Alternative Wind-Down Activities
Read a Physical Book
Reading printed material helps relax the mind without blue light exposure.
Practice Relaxation Techniques
Deep breathing or gentle stretching can prepare the body for sleep.
Listen to Calming Music or Podcasts
Audio-only content is less stimulating than visual media.
