Health tracking involves monitoring various aspects of an individual's health, such as physical activity, nutrition, sleep patterns, and vital signs. This can be done using wearable devices, mobile apps, or traditional methods like journals. The goal is to gather data that can help individuals understand their health better and make informed decisions. By analyzing health data, users can identify trends and areas for improvement. For example, tracking exercise can motivate individuals to stay active, while monitoring diet can help in making healthier food choices. Overall, health tracking promotes awareness and encourages proactive health management.
