How Technology Shapes Your Sleep Patterns

The Dual Role of Technology in Sleep

Technology and sleep have a complex relationship. Devices like smartphones can disrupt rest, but tools like sleep trackers can enhance it. Studies show excessive screen time delays melatonin production, yet strategic tech use can support better sleep hygiene.

Blue Light’s Impact on Your Brain

Blue light from screens mimics daylight, tricking your brain into staying alert. This delays sleep onset and reduces deep sleep phases.

Why Timing Matters

Evening screen use has the strongest effect on circadian rhythms.

Reducing Exposure

Use blue light filters or glasses to minimize disruption.

Enable Night Mode

Most devices have settings to warm screen tones.

Set a Tech Curfew

Stop screens 1-2 hours before bed.

Social Media and Mental Stimulation

Endless scrolling keeps your brain engaged, increasing stress and delaying relaxation.

Limit Notifications

Turn off alerts to avoid late-night distractions.

Curate Your Feed

Follow calming content to reduce overstimulation.

Unplug Gradually

Replace scrolling with reading or music.

Charge Devices Elsewhere

Keep phones out of the bedroom.

Not all technology harms sleep. Apps and devices can promote better rest when used wisely.
