Good stress, or eustress, is a positive form of stress that motivates and energizes individuals, enhancing performance and personal growth. It is short-term and manageable, associated with challenges that lead to fulfillment. Toxic stress, on the other hand, is harmful and prolonged, resulting from persistent, overwhelming pressures. It can lead to negative health effects, such as anxiety, depression, and chronic illness, impacting overall well-being and requiring effective intervention.
