Understanding and Improving Sleep Efficiency
Striving to get a good night’s sleep but often find yourself lying awake for hours? Your sleep efficiency might be the culprit. According to a recent article by Men’s Health, sleep efficiency is a crucial factor in determining how well-rested you feel. Here’s a summary of the article “What Is Sleep Efficiency—And How Can You Improve It?”
What is Sleep Efficiency?
Sleep efficiency refers to the percentage of time you spend asleep compared to the total time you spend in bed with the intention of sleeping. Dr. Zachary Strumpf, a sleep medicine physician at University Hospitals in Cleveland, Ohio, explains that it’s different from simply getting a better night’s sleep. Instead, it measures how effectively you can fall and stay asleep.
A high sleep efficiency score doesn’t always equate to adequate sleep. For instance, someone might sleep only five hours but still have high sleep efficiency. According to Dr. Nishay Chitkara, director of sleep medicine at NYC Health + Hospitals/Bellevue, it’s crucial to not only have good sleep efficiency but also get enough sleep.
Calculating Sleep Efficiency
To calculate sleep efficiency, divide the total minutes you spend asleep by the total minutes you spend in bed trying to sleep. A sleep efficiency score of 85% to 90% or greater suggests you have little trouble falling and staying asleep. However, a score below 80% indicates poor sleep efficiency, which may necessitate improvement in sleep habits or addressing underlying medical conditions.
Factors Affecting Sleep Efficiency
Several factors can impact sleep efficiency, including diet, exercise levels, sleep schedules, and sleep environments. Poor sleep efficiency can lead to numerous health issues, including lower mood, cognitive ability, and productivity. It’s also linked to increased mortality risk in older adults.
Improving Sleep Efficiency
Improving your sleep efficiency involves optimizing your sleep hygiene. Here are some actionable tips:
- Maintain a Regular Sleep Schedule: Go to bed and wake up at the same times daily.
- Get Seven to Eight Hours of Sleep: Ensure you’re getting enough sleep each night.
- Avoid Caffeine and Alcohol: Stay away from caffeine late in the day and avoid alcohol three to four hours before sleep.
- Limit Screen Time: Avoid watching TV or scrolling your phone an hour before bed.
- Avoid Napping: Cut out napping to help improve nighttime sleep efficiency.
- Optimize Your Sleep Environment: Ensure your bedroom is conducive to sleep. Consider sleep cooling strategies like using a fan, keeping the room cool, and using cooling mattress toppers.
Role of Sleep Trackers
Sleep trackers can be beneficial in improving sleep efficiency. They provide insights into your sleep habits and environmental factors affecting sleep, such as light, temperature, and noise levels. By monitoring health metrics like heart rate, movement, body temperature, and blood oxygen levels, you can make informed adjustments to enhance your sleep quality.
When to See a Doctor
If you experience trouble falling or staying asleep, waking up frequently during the night, or feeling excessively sleepy during the day, it’s important to consult a doctor. Persistent sleep issues might require evaluation by a sleep specialist, especially if symptoms last for more than three months or if your sleep disruptions affect your bed partner.
Sleep apnea is another condition to watch for. Symptoms include snoring, gasping or choking during sleep, or periods of not breathing. If you notice these signs, seek medical advice promptly. Total Snooze can get you started with a free sleep quiz.

Implementing good sleep hygiene practices, using sleep trackers, and consulting with healthcare professionals when necessary can help you optimize your sleep.
