Asthenic describes a state of physical weakness or lack of energy. Imagine feeling constantly tired, even after a full night's sleep; that's often what being asthenic feels like. It's more than just being a bit tired; it's a persistent and noticeable lack of strength. Think of it as the opposite of feeling vigorous and full of pep. It can be caused by various factors, including illness, poor nutrition, or lack of sleep. If youβre feeling asthenic, getting checked out by a doctor is wise.
