Noncommunicable Diseases (NCDs) are one of the major health challenges, which has caused global concern due to their magnitude and high social cost. Industry 4.0 will significantly bring in IoT in the healthcare sector in an age of great growth in connected devices (up to 100 billion by 2030). The COVID-19 pandemic further accentuates the importance of using IoT in healthcare settings for both the providers and NCD patients due to controlled movements and enforced self-isolation throughout the world including Malaysia. In this regard, the improvement of “connected devices” has had a remarkable effect upon the entire healthcare sector and has been noticeably appreciated in “remote clinical monitoring”, “chronic disease management”, “preventive care”, and “assisted living” for senior NCD patients. This study intends to interpret the significance of IoT in connection with wearable technologies and digital healthcare. The study discusses several benefits of IoT like reducing cost, rising profits for the healthcare service providers in Malaysia, a higher level of success and productivity, and precision of “health monitoring and treatment systems”. The insights of this study will help the elderly NCD patients’ community and healthcare providers to recognise the significance of IoT Enabled Health Monitoring and Assistive Systems due to their significant contribution to improving healthcare in the country in the long run.
