Abstract
The Hajj season poses significant health risks due to extreme heat and the dense movement of millions of pilgrims. To combat heat-related illnesses (HRIs), Saudi authorities have implemented measures such as pre-travel health education, heat-reflective pavements, air-conditioned tents, mist sprayers, and water distribution. These efforts, coordinated with government agencies and healthcare providers, have effectively reduced HRIs. However, overcrowding during key rituals like Tawaf and Ramy al-Jamarat heightens the risk of HRIs and the spread of infections. Additionally, the surge in emergency cases during large-scale events can strain healthcare services, particularly for vulnerable groups.

To address the challenges, a smart system for continuous body temperature monitoring is proposed to improve healthcare management during such events. This system provides real-time vital sign data, enabling early detection of health risks like heatstroke and dehydration, while helping healthcare providers prioritize care based on the severity of conditions.

In this experiment, users were classified based on their body temperature, enabling the efficient allocation of medical resources to those in greatest need. This proactive strategy enhances patient outcomes, minimizes delays in care, and improves healthcare system efficiency, especially in scenarios with limited hospital beds and urgent decision-making requirements.

Saudi Arabia’s advanced digital infrastructure enables real-time health monitoring for pilgrims, ensuring swift medical care and efficient resource allocation. Aligned with Vision 2030, this apparatus highlights the Kingdom’s dedication to the safety and well-being of ‘Guests of Allah’.
