When Tiredness Stops Being Normal
Everyone gets tired. Fatigue that lingers for weeks despite rest is a different signal, and worth taking seriously.

What this is
Persistent fatigue is one of the most common reasons men over 35 start paying attention to their health, and it rarely has a single cause. This page explains how sleep, hormones, mood, nutrition, and underlying conditions can each contribute, and why ongoing fatigue deserves a proper evaluation rather than another cup of coffee.
Why it happens
Fatigue is the body's general-purpose alarm. Because so many systems can trigger it, lasting tiredness usually reflects a combination of factors, and sometimes a condition that needs medical attention.
Common causes
Poor or insufficient sleep, sleep apnea, stress and burnout, low mood, nutritional gaps, thyroid or hormone issues, and a range of underlying medical conditions.
Possible paths forward
Looking honestly at sleep quantity and quality first; tracking when the fatigue is worst; and seeing a licensed provider if it persists beyond a couple of weeks, since persistent fatigue can point to a treatable condition.
