arousal and stress

Arousal refers to the physiological and psychological state of being awake and alert, with increased mental and physical responsiveness. It is characterized by heightened activity or engagement, often resulting from stimulation or excitement. Stress, on the other hand, is a reaction to events or situations that are perceived as demanding, challenging, or threatening. It involves both psychological and physiological responses, such as heightened anxiety, tension, increased heart rate, and release of stress hormones.
