Fatigue is temporary loss of strength and energy resulting from hard physical, mental, or nervous exertion (stress).
Explanation:
Fatigue is a temporary loss of strength and energy If we lose strength we have mainly done a hard physical activity, however, If we lose energy we have done a very demanding activity for our brain (mental activity), muscles, and nervous system.
