A peaceful night of slumber can leave you feeling more energized and alert when you wake up. But sleep quality is only part of how sleep affects your energy levels throughout the day. Sleep satisfaction also influences how energized you feel at any given moment, and better sleep satisfaction can make people feel more invigorated.


Sleep satisfaction—a subjective evaluation of how satisfied a person feels with his or her sleep — can be influenced by factors in the bedroom environment, such as light, noise, and temperature. It is frequently used along with sleep quantity (the number of hours slept) and sleep quality (the caliber of sleep) to assess your overall state of sleep. When satisfaction, quality, or quantity improves, energy levels can improve as well.


Sleep Restores Energy

During high-quality sleep, your body restores many functions it calls on during daily life, such as temperature regulation, a strong immune system, steady hormone levels, and good appetite. All of these factors play a role in how much energy you have. To operate at your peak potential, you need to maintain these functions through quality sleep.


Sleep Satisfaction Matters

Feeling good about the sleep you got sets you up for other positive emotions. Sleep satisfaction can lead to feelings of greater energy, whereas depression is often linked with feelings of fatigue. So, while sleep satisfaction is a subjective assessment, the outcome of how satisfied you feel could have measurable ramifications on your wellbeing.


Poor Sleep Quality Slows You Down

Beyond making you feel groggy when you wake up, poor sleep quality can make you feel sluggish throughout the day. For example, poor sleep quality has been linked to obesity and weight gain, and not getting enough sleep is also associated with an increase in calorie intake without any increase in activity level. Obesity and its associated health problems, such as heart disease and diabetes, can lower your energy level by making you feel fatigued during the day. Finally, a poor night of sleep can impact your immune system, making you more susceptible to colds and flus and lowering your energy levels for days at a time.


How to Boost Sleep Satisfaction

If you find yourself feeling less than satisfied with your sleep, there are measures you can take to improve your sleep experience.6 Fresh bedding, low noise levels, and cool temperatures in your bedroom all contribute to a more satisfying sleep experience. By taking steps to increase your sleep satisfaction, you can wake up feeling refreshed with consistently high energy levels throughout the day.
