The formula to calculate sleep efficiency is:
\[ SE = \frac{TS}{TB} \times 100 \]
Where:
Let's say the total time asleep (\( TS \)) is 6 hours and the total time in bed (\( TB \)) is 8 hours. Using the formula:
\[ SE = \frac{6}{8} \times 100 \]
We get:
\[ SE = 0.75 \times 100 = 75\% \]
So, the sleep efficiency (\( SE \)) is 75%.
Sleep efficiency is the percentage of time spent asleep while in bed. It is calculated by dividing the total time asleep by the total time spent in bed and multiplying by 100. This metric is important for assessing the quality of sleep and identifying potential sleep issues.
