The Science of Blue Light and Sleep Quality
How Blue Light Disrupts Rest
Melatonin Suppression
Blue light from screens reduces melatonin, making sleep harder.
This delays sleep onset and shortens sleep duration.
Impact on Circadian Rhythm
Evening exposure shifts your internal clock later.
This causes grogginess and poor sleep quality.
Digital Habits That Harm Sleep
Late-Night Device Use
Phones and tablets before bed increase alertness.
Set a digital curfew to protect your rest.
Notifications and Stress
Alerts and messages disrupt relaxation and sleep cycles.
Turn off notifications at night for better rest.
Tips to Reduce Blue Light and Improve Sleep Quality
Setting Healthy Boundaries
Use Night Mode Features
Enable blue light filters on all devices after sunset.
This reduces the impact on your sleep quality.
Establish a Screen-Free Hour
Avoid screens for at least one hour before bed.
Replace screen time with reading or meditation.
Optimizing Your Bedroom
Remove Devices from the Room
Charge phones and tablets outside your bedroom.
This strengthens the association between bed and sleep.
Prioritize Sleep Over Digital Distraction
Set a consistent bedtime and stick to it for better sleep quality.
Less blue light means deeper, more restorative rest.
