Juntendo University and NTT Communications Co., Ltd. conducted a demonstration experiment to develop a stress measurement system using wearable biosensors, etc. on November 2018, 11 with the aim of widely spreading the effect of one of the horticultural therapies, "Agri-Healing". Start from the day.
In recent years, the number of patients with psychiatric disorders in Japan has exceeded the number of patients with the four major illnesses (malignant neoplasm, diabetes, cerebrovascular disease, and ischemic heart disease), reaching about 4 million in FY2014.As a result, the annual medical expenses for patients with mental illness amount to about 400 trillion yen, which is equivalent to about 1% of the total medical expenses.In modern society, there is an urgent need to create a method for controlling stress and an environment for reducing stress.
Juntendo University is focusing on the horticultural therapy "Agri-Healing", which improves mental illness through flower appreciation and farm work, as a primary preventive method, and is working on quantifying and quantifying (visualizing) the stress-reducing effect.However, the saliva collection kit used to measure the stress-reducing effect is expensive, and people who have difficulty producing saliva, such as the elderly and patients with mental illness, may feel pain.Therefore, even if the mitigation effect of agri-healing is proved by medical science, it is difficult to utilize it as a stress countermeasure program in companies and schools.
Therefore, this time, Juntendo University will conduct a demonstration experiment in collaboration with NTT Communications in order to realize the visualization of stress reduction effect more easily and with high accuracy.We use a wearable biosensor "hitoe" that can measure heartbeats just by wearing it, and a data distribution platform that collects, stores, and analyzes data.
In the demonstration experiment, we verified a method to measure the autonomic nerves of agri-healing participants in real time with "hitoe".From the obtained data, we will establish a highly accurate and simple measurement method for stress reduction effect and its algorithm. NTT Communications will develop software that reflects the algorithm and incorporate it into the data distribution platform to visualize stress.
In the future, we aim to utilize agri-healing for the prevention and future treatment of mental illness by using this measurement system that uses "hitoe" and a data distribution platform instead of saliva collection.
