What is now believed to be primarily a result of mental origin?

Fatigue is often recognized as a condition that can arise predominantly from mental origins, particularly due to cognitive and emotional factors. It extends beyond just physical exhaustion and can be heavily influenced by one's mental state, such as stress levels, emotional well-being, and overall mental health. Individuals experiencing high levels of mental stress may find themselves feeling fatigued even if they have not engaged in significant physical activity.

This understanding is vital in fields such as cosmetology, where professionals might observe how clients' mental states can impact their physical appearance and energy levels. For example, a client may appear to suffer from fatigue due to long-term stress or poor mental health, rather than merely lack of sleep or physical exertion.

In contrast, while stress, anxiety, and depression also have mental components and impacts, they are typically recognized for their broader psychological implications and effects. Stress can be a contributing factor to fatigue but is not solely a result of mental origins, as it can stem from external pressures. Anxiety and depression often manifest with physical symptoms, but the question specifically addresses fatigue's primary origin, highlighting its close ties to mental factors.
