Feeling tired all the time isn’t a personal failure — it’s a signal. Modern life places a load on your body that it was never designed for: constant stimulation, irregular sleep, processed food, low‑grade stress, and long periods of sitting. These inputs drain energy just as much as physical exertion. When your biology is overwhelmed, tiredness becomes the default state. Understanding the mechanisms behind fatigue helps you make small, targeted changes that restore stability, clarity, and consistent energy.
