What symptom might indicate a problem with sleep quality?

Excessive daytime fatigue is a significant symptom that can indicate a problem with sleep quality. When a person experiences poor sleep, it often leads to insufficient restorative processes during the night, impacting their ability to feel refreshed and alert during the day. This fatigue is typically associated with several sleep disorders and can impede functioning, leading to difficulties in concentration, mood disturbances, and a reduced ability to perform daily tasks effectively.

In contrast, improved concentration, heightened alertness, and reduced stress levels would suggest that an individual is likely receiving adequate restorative sleep and not experiencing issues with sleep quality. These symptoms are commonly associated with healthy sleep patterns, further highlighting the impact of nighttime rest on daytime performance and well-being. Thus, the presence of excessive daytime fatigue serves as a critical indicator of underlying issues with sleep quality.
