Everyone feels tired at some point – getting too little sleep, recovering from common illnesses, an unexpectedly heavy workload, partying into the night. But when should tiredness be taken seriously?
Exhaustion that lingers isn’t the norm. In a healthy person, exhaustion is temporary and remedied by extra rest. But there’s a second kind of tiredness that’s prolonged.
The term “fatigue” describes an overall feeling of a lack of vitality. People who are fatigued are deficient in energy and usually lack motivation. It’s not the same thing as feeling sleepy, yet drowsiness can be one of the symptoms. Fatigue is also different from weakness, which is a lack or loss of muscle strength.
