Fatigue and lethargy are commonly recognized as the first signs of physical stress on the human body. When an individual experiences stress, whether it be from physical exertion, mental pressure, or emotional strain, the body's natural response often includes feelings of tiredness or a lack of energy. This is due to various physiological changes that occur in response to stress, such as the release of stress hormones like cortisol, which can affect overall energy levels and lead to sensations of exhaustion.

While increased energy, improved focus, and rapid weight loss may occur as a result of certain stress reactions in specific contexts, they are not typically the initial or universal signs of physical stress. In fact, increased energy and improved focus can sometimes be seen in short bursts of acute stress. However, sustained stress tends to manifest more prominently as fatigue and lethargy, marking it as a primary indicator of the body's struggle to adapt to ongoing stressors.
