A "Stress Gauge" is a tool designed to measure and assess an individual's stress levels. It can take various forms, such as a physical device, an app, or a questionnaire. By evaluating factors like heart rate, sleep patterns, and emotional well-being, the Stress Gauge provides insights into how stress affects a person's daily life. Using a Stress Gauge can help individuals identify stress triggers and manage their responses more effectively. This awareness can lead to healthier coping strategies, such as mindfulness or exercise, ultimately promoting better mental health and overall well-being.
