Input your screen exposure data

Formula

Screen impact score = (Bedtime screen time × 25) + (Daily screen time × 1.5), capped at 100.

Blue light exposure = (Bedtime screen time × blocking factor × 100) + (Daily screen time × blocking factor × 2).

Blocking factor = 1 - (Blue light blocking usage / 10) × 0.6 (reduces exposure up to 60%).

Bedtime screen time (within 2 hours of sleep) has a much greater impact than general daily screen time due to melatonin suppression and mental stimulation.

Steps

  • Enter total daily screen time in hours.
  • Enter hours of screen time in the 2 hours before bedtime.
  • Rate your overall sleep quality (1 = poor, 10 = excellent).
  • Optionally rate your blue light blocking usage (0 = none, 10 = always use filters/glasses).
  • Review screen exposure impact, recommendations, and optimal screen cutoff time.

Complete guide snapshot

Screen exposure, particularly in the hours before bedtime, significantly impacts sleep quality through blue light exposure (which suppresses melatonin) and mental stimulation. Understanding this relationship helps optimize bedtime routines for better rest.

Use this analyzer to assess how your screen time patterns affect sleep quality and receive personalized recommendations for reducing screen exposure before bed.

FAQs

How does screen time affect sleep?

Screen time, especially before bed, exposes you to blue light which suppresses melatonin production, delays sleep onset, and reduces sleep quality. The light and content can also be mentally stimulating.

What is blue light and why is it problematic?

Blue light is a high-energy visible light emitted by screens. It suppresses melatonin, the hormone that regulates sleep-wake cycles. Exposure before bedtime can delay sleep by 30-60 minutes or more.

How long before bed should I stop using screens?

Ideally, stop using screens 1-2 hours before bedtime. However, even 30-60 minutes can help. The exact time depends on individual sensitivity and whether you use blue light filters.

Do blue light filters or glasses help?

Yes, but they don't eliminate the problem completely. Blue light filters can reduce melatonin suppression by 50-60%, but the mental stimulation from content and the light itself still affect sleep quality.

Does the type of screen matter?

Yes. LED/LCD screens (phones, tablets, TVs) emit more blue light than e-ink or OLED screens. Brightness level also matters - dimmer screens have less impact than bright ones.

Can I use devices with night mode enabled?

Night mode (blue light filters) helps but isn't a complete solution. While it reduces blue light exposure, the mental stimulation from engaging content can still interfere with sleep quality.

What about audiobooks or podcasts on devices?

Audio content is generally better than visual content, but using a screen device still exposes you to light. Consider using a separate audio device or keeping the screen off/turned away.

How does screen time throughout the day affect sleep?

Excessive screen time during the day can lead to eye strain, mental fatigue, and disrupted circadian rhythms, all of which can indirectly affect nighttime sleep quality even if you avoid screens before bed.

Are there apps that can help?

Yes. Screen time tracking apps can help monitor usage. Blue light filter apps can reduce exposure. Some devices have built-in features like Night Shift (iOS) or Night Light (Windows) that adjust colors.

What are good alternatives to screen time before bed?

Good alternatives include reading (physical books or e-ink), gentle stretching, meditation, journaling, listening to calming music, or having a warm bath. These activities help prepare your body for sleep.
