Sleep quality profoundly impacts our daily lives. U.S. sleep - related research indicates that a third of adults rate their previous night's sleep as "fair" or "poor".
Inadequate or poor - quality sleep can lead to daytime sleepiness and discomfort. For those with excessive daytime sleepiness (EDS), the issues may be more severe. If you constantly feel tired and lack energy during work, study, or daily activities, it can greatly affect your quality of life.
This article will analyze the differences between daytime fatigue and EDS, explore their symptoms and causes, and provide practical sleep - improvement advice and medical guidance.
Definition of Daytime Fatigue Daytime fatigue is a sustained state of physical and mental exhaustion. The Mayo Clinic explains it can weaken focus, drive, energy levels, and even impact emotional well - being. The Cleveland Clinic notes fatigue differs from regular sleepiness: sleepiness can be relieved by extra sleep, while fatigue may persist long - term and disrupt normal life.

Alerting Data
EDS affects 10% - 20% of people, increasing accident risks (e.g., 91,000 fatigue - related driving accidents in 2017).
The two may coexist and require professional evaluation.

Common causes
（1）Sleep deprivation or poor - quality sleep | Shift work
