Quick Answer
No, persistent fatigue is NOT a normal part of aging! Waking up still feeling exhausted despite a full night's sleep is one of the most frustrating experiences for older adults. This persistent fatigue is not normal aging and deserves attention. Understanding why you're always tired is the first step toward restoring your energy and enjoying life fully.
According to the National Institute on Aging, fatigue in older adults is often caused by treatable factors rather than aging itself. Most fatigue in seniors has identifiable, treatable causes like medical conditions, medications, or lifestyle factors. If you're constantly tired, consult your healthcare provider.
