Advanced wearables help individuals, particularly those with diabetes, monitor their blood glucose levels continuously. Oxygen saturation (SpO2) tracking has become vital, especially during the COVID-19 pandemic, as it serves as an essential marker of disease severity. Additionally, some wearables provide electrocardiogram (ECG) data, enabling early detection of heart arrhythmias, while others monitor respiratory rate, offering insights into respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). These metrics collectively enhance personalized healthcare management and promote healthier living.

_{Functions of Wearables in Healthcare}

Wearable technology plays a crucial role in healthcare by serving several essential functions that enhance both diagnosis and ongoing health management. One key function is monitoring, where wearables continuously track health indicators such as heart rate, physical activity, and sleep patterns. This allows healthcare providers to remotely monitor a patient’s health, which was especially useful during the COVID-19 pandemic for tracking symptoms and long-term effects. Screening is another vital function, with wearables increasingly being used to screen for health conditions like a trial fibrillation, sleep apnea, and cardiovascular diseases. Early screening leads to timely interventions and improved patient outcomes. Wearables are also capable of  detection, as they can identify early signs of illness or infection. This was demonstrated during the pandemic when wearables helped detect pre-symptomatic COVID-19 and seasonal influenza, enabling early treatment and reducing disease spread. Lastly, wearables assist with prediction by leveraging advanced algorithms to predict health outcomes, such as mortality risk, likelihood of hospitalization, or worsening of chronic conditions like COPD. These predictive analytics provide critical insights that help in effectively managing chronic illnesses and improving overall health outcomes.

Benefits of Wearable Technology

The adoption of wearable technology in healthcare brings numerous benefits to both patients and healthcare systems. One major advantage is  real-time monitoring, where wearables continuously track health metrics, allowing individuals and healthcare providers to quickly identify any changes. For example, constant heart rate monitoring can detect irregularities, prompting immediate medical attention and potentially preventing severe complications. This leads to improved patient outcomes, as the data provided by wearables enable proactive management of patients' health, reducing the need for frequent in-person visits. Wearables also enhance patient engagement, empowering individuals to take charge of their health by providing real-time feedback, which encourages healthier behaviors and more informed lifestyle choices.

Another key benefit is cost reduction, as wearables help lower healthcare costs by enabling early detection of health issues and reducing hospital admissions. Remote monitoring minimizes the need for frequent consultations, saving both time and resources for patients and providers.    Remote monitoring  is particularly beneficial for patients with chronic conditions, allowing healthcare providers to track their health remotely, especially in rural or underserved areas where access to healthcare is limited. Wearables also support     data-driven decision making by collecting vast amounts of health data, allowing providers to make more informed, personalized treatment plans. Lastly, wearables provide valuable     behavioral insights     by tracking physical activity, sleep patterns, and dietary habits, helping individuals make healthier choices and assisting healthcare providers in tailoring personalized health plans based on lifestyle factors.
