Let's dive into the world of fatigue and its implications for your heart health together.
Gaining More Information About Fatigue Fatigue extends beyond just tiredness following a prolonged day or inadequate sleep. It manifests as a constant energy depletion and drive, disrupting daily routines and overall well-being of a person.
Fatigue may manifest physically, mentally, or both, with causative factors differing among each individual.
Although fatigue is often used synonymously with tiredness and sleepiness, in medical terms, it represents a distinct ailment.
According to the Cleveland Clinic, individuals experiencing fatigue feel extremely drained to the extent that it noticeably disrupts their daily activities. While feeling tired might result in slowness at work, fatigue could lead to missing work altogether.

Other indicators of fatigue include:
- Daytime drowsiness
- Difficulty maintaining focus or concentration
- Overall sense of physical and mental discomfort
