Sleep efficiency is a measurement often used to assess the effectiveness of insomnia treatment. This measurement is a percentage value that is calculated by dividing the amount of time you spend sleeping by the amount of time you spend in bed.
Your sleep efficiency = (time you spend sleeping / time you spend in bed) x 100%
Let's say you spend 8 hours in bed but only sleep for 6 hours of that time
Your sleep efficiency = (6 hours / 8 hours) x 100%
= 0.75 x 100%
= 75% sleep efficiency
For the majority of us, our bedtime and our sleep time are not a synchronised event.
Even after the laptops, tablets, books, and phones are put away, our minds can still be racing in the dark. Unfortunately, this can lead some of us into a toss-and-turn bedsheet tango – the harder we try to get to sleep the more it evades us.
Conversely, others begin their journey to dreamland the moment their heads hit the pillow - but lo and behold – they may awake in the wee hours of the morning and struggle to get back to sleep.
