Explanation

Getting enough hours of sleep doesn't always mean you will feel rested during the day. Sleep disorders can affect the quality of your sleep, leading to something called nonrestorative sleep, where you don't feel refreshed even after a full night's sleep.

Nonrestorative Sleep

  • Nonrestorative Sleep: This is when you sleep enough hours but still feel tired. According to research, this can happen because your sleep is not deep or restful enough.

Causes of Poor Sleep Quality

  • Sleep Disorders: Problems like sleep apnea can disturb your sleep without you knowing it. This can make you feel tired during the day. Sleep-related breathing disorders can interrupt your sleep and affect how rested you feel.

Conclusion

Even if you sleep a lot, if your sleep is not good quality, you can feel tired. If you are worried about your sleep, it might be helpful to talk to a healthcare provider for advice.
