1. What is Sleep Efficiency Score?

The Sleep Efficiency Score is a measure of sleep quality that calculates the percentage of time spent asleep while in bed. It provides insight into how effectively you're using your time in bed for actual sleep.

2. How Does the Calculator Work?

The calculator uses the Sleep Efficiency equation:

Where:

• \( SE \) — Sleep Efficiency Score (%)
• \( TST \) — Total Sleep Time (minutes)
• \( TIB \) — Time In Bed (minutes)

Explanation: The equation calculates the ratio of actual sleep time to total time spent in bed, expressed as a percentage.

3. Importance of Sleep Efficiency

Details: Sleep efficiency is a key indicator of sleep quality. Higher efficiency scores indicate better sleep quality, while lower scores may suggest sleep disturbances or insomnia.

4. Using the Calculator

Tips: Enter total sleep time and time in bed in minutes. Both values must be positive numbers, and sleep time cannot exceed time in bed.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good sleep efficiency score?
A: Generally, 85% or higher is considered good sleep efficiency. Scores above 90% are excellent, while scores below 85% may indicate sleep problems.

Q2: How is sleep efficiency different from sleep duration?
A: Sleep duration measures total time asleep, while sleep efficiency measures how effectively you use your time in bed for sleeping.

Q3: What factors can affect sleep efficiency?
A: Factors include sleep disorders, stress, caffeine intake, bedroom environment, and sleep hygiene practices.

Q4: How can I improve my sleep efficiency?
A: Maintain consistent sleep schedule, create comfortable sleep environment, limit screen time before bed, and avoid caffeine/alcohol close to bedtime.

Q5: Should I track sleep efficiency regularly?
A: Regular tracking can help identify patterns and effectiveness of sleep improvement strategies, but occasional measurement is sufficient for most people.
