Tiredness is a state of physical or mental fatigue that can result from various factors, including lack of sleep, prolonged activity, or emotional stress. It often leads to a decrease in energy levels, motivation, and concentration, making it difficult to perform daily tasks effectively. When someone feels tired, their body may signal the need for rest or sleep. Common symptoms include yawning, heavy eyelids, and a general sense of lethargy. Addressing tiredness typically involves improving sleep quality, managing stress, and maintaining a balanced diet to support overall well-being.
