sömneffektivitet

Sömneffektivitet, often translated as sleep efficiency, is a measure of how much time a person spends asleep while in bed. It is calculated by dividing the total time spent asleep by the total time spent in bed and then multiplying by 100 to express it as a percentage. For example, if someone spends 8 hours in bed and sleeps for 6 hours, their sömneffektivitet is (6 / 8) * 100 = 75%.

A high sömneffektivitet is generally considered desirable, indicating that a person is sleeping soundly and without significant interruptions. Typical benchmarks suggest that a sömneffektivitet of 85% or higher is considered good for healthy adults. Lower sömneffektivitet can be an indicator of sleep disturbances, such as difficulty falling asleep, frequent awakenings, or restless sleep.

Factors that can influence sömneffektivitet include sleep disorders like insomnia, environmental factors such as noise or light, lifestyle habits like caffeine or alcohol consumption, and psychological factors like stress or anxiety. Monitoring sömneffektivitet can be a useful tool in assessing sleep quality and identifying potential issues that may require attention. In clinical settings, it is often measured using actigraphy or polysomnography.
