Smart medical devices play an increasingly vital role in enhancing human health through their ability to continuously monitor various vital signs. These devices contribute to the early detection of diseases, enabling individuals to take preventive measures before conditions worsen. For example, smartwatches like the Apple Watch and Fitbit monitor heart rates and alert users when irregularities such as atrial fibrillation are detected, which may indicate serious cardiac issues. Additionally, blood glucose monitoring devices like the Dexcom G7 assist diabetic patients in maintaining stable blood sugar levels, reducing the risk of long-term complications.<br />Moreover, these devices provide real-time data that help doctors monitor their patients remotely, improving the chances of timely medical intervention when needed. Integrated health applications also encourage individuals to adopt healthier lifestyles by offering personalized advice on nutrition, sleep, and physical activity. For instance, devices like the Withings Body+ can track weight and body mass index (BMI), motivating users to maintain a healthy weight and thereby lowering the risk of cardiovascular diseases.<br />Furthermore, smart devices play a crucial role in combating epidemics by tracking the spread of diseases. During the COVID-19 pandemic, contact-tracing applications helped limit the virus's spread by notifying individuals of potential exposure. Devices like the Kinsa Thermometer monitor health patterns within communities, enabling health authorities to respond swiftly to any rise in infection rates. Additionally, artificial intelligence integrated into some devices has enhanced diagnostic accuracy; for example, the SkinVision app helps detect skin cancer early by analyzing skin images.<br />With these advanced capabilities, smart medical devices have become essential tools for disease prevention and public health promotion. They not only aid in detecting health issues but also motivate individuals to adopt healthier lifestyles, reducing the likelihood of chronic diseases and improving overall quality of life.<br />Almustaqbal University, the first university in Iraq.
