Exhaustion, or fatigue, is a state of extreme tiredness that can result from physical or mental exertion. It often occurs after prolonged activity, lack of sleep, or stress, leading to decreased energy levels and motivation. Symptoms may include weakness, irritability, and difficulty concentrating. Chronic fatigue can be a sign of underlying health issues, such as anemia, depression, or chronic fatigue syndrome. It is important to address the causes of fatigue through proper rest, nutrition, and medical consultation if necessary. Managing stress and maintaining a balanced lifestyle can also help alleviate feelings of exhaustion.
