Do you wake up feeling tired even after spending enough hours in bed? Do you struggle with daytime fatigue, brain fog, mood swings, or low energy? These may be common symptoms of poor sleep quality.
Sleep is one of the most important foundations of physical and mental health. However, many adults focus only on the number of hours they sleep and overlook the quality of that sleep. Even if you sleep for seven or eight hours, disrupted or low-quality sleep can leave the body feeling exhausted and unfocused.
In this article, you’ll learn the most common signs of poor sleep quality, possible lifestyle factors that affect sleep, and natural habits that may support deeper and more restorative rest.

This may happen when sleep is:
