The Internet of Behaviour (IoB) is an effort to dissect behavioural patterns as explained by data collection. IoB is an extension of the Internet of Things (IoT). Therefore, both are anticipated to experience exponential growth in the upcoming years. Healthcare firms have many opportunities to employ IoB to provide individualised services and anticipate patients’ behaviour. As behaviour and analysis are closely related to psychology, many techniques exist to collect relevant data. The IoB improves the doctor’s and patient’s experience. As IoT and IoB are interconnected, IoB technology collects and analyses data depending on user activity. These offer a practical technique for developing real-time remote health monitoring systems. This technology aids in the optimisation of auto insurance premiums in the healthcare sector. It tries to alter patient behaviour in order to improve the treatment process. IoB has applications in various areas, including retail and entertainment, and has the potential to change the marketing sector significantly. This technology is helpful for the appropriate analysis and comprehension of behavioural data used for creating valuable services for treatment. The primary purpose of this paper is to study IoB and its need for healthcare. The working process structure and features of IoB for the healthcare domain are studied. This paper further identifies and analyses the significant applications of IoB for healthcare. In the future, IoB technologies will give us a higher quality of life and well-being. IoB is the ideal fusion of technology, data analytics, and behavioural science. This will help healthcare professionals collect data and analyse the patient’s behaviours for an efficient treatment process. The IoB will be the digital ecosystem’s intelligence in a few years.
