The Science Behind Blue Light and Sleep Disruption
How Blue Light Impacts Melatonin Production
Suppression of Sleep Hormones
Blue light from screens delays melatonin release, making it harder to fall asleep.
Increased Alertness at Night
Exposure to screens tricks the brain into thinking it’s daytime.
Common Sources of Nighttime Screen Exposure
Smartphones and Tablets
These devices emit high levels of blue light due to close proximity.
TVs and Computers
Larger screens can also contribute to sleep disruption.
Practical Ways to Reduce Screen Time Before Bed

Avoid Screens 1-2 Hours Before Sleep
Replace screen time with reading or relaxation techniques.
Use Night Mode Features
Enable blue light filters on devices if screen use is unavoidable.
Alternative Activities for Better Sleep
