News:Press Conference: Research on Material Diminishing Insomnia and Asthenopia
December 21, 2017


On December 21, 2017, Yamamoto Corporation held a press conference at MyDome Osaka in Osaka City. Dr. Kiyoshi Morioka presented the results of research on a material that emits infrared rays at normal temperatures.

The following is an extract from a press release:

From an early stage, Yamamoto Corporation has been focusing on “insomnia” and “asthenopia,” which are big issues affecting many people living in the current era. We verified a material that emits infrared rays at normal temperatures through a double blind test jointly with Dr. Kiyoshi Morioka, a professional doctor solving asthenopia. Furthermore, we are considering making an academic presentation on it in fiscal 2018.

With this verification, it was revealed that not only are users able to sleep well without experiencing insomnia by warming their body with the material that emits infrared rays at normal temperatures, but also that it helps in eliminating insomnia by significantly changing the “balance between beta waves and alpha waves inside the brain” and the “amount of mid-alpha waves inside the brain.”

We conducted the verification through a double blind test without telling the trial subjects whether they are using a simulated material or the material that emits infrared rays at normal temperatures.

As a result, there were almost no changes in the balance between beta waves and alpha waves when the subjects that used the simulated material and the average value of mid-alpha waves was 7%. As for the subjects that used the material that emits infrared rays at normal temperatures, the balance between beta waves and alpha waves resulted in the beta waves decreasing by 1.7 times while the alpha waves increasing by 2.2 times, showing an improvement in the quality of sleep. In addition, the average value of mid-alpha waves was 25% which is approximately 3.5 times higher than the value gained by using the simulated material.

Next, we will show the verification results for asthenopia. We formerly measured the degree of asthenopia before wearing the material that emits infrared rays at normal temperatures and 30 minutes after wearing it and, based on the results of thermography, we were able to verify a significant difference. After that, we commercialized the eye mask for warming the eyes at fixed temperatures. More than 1,000 opinions of praise were received by Dr. Kiyoshi Morioka from the users.

Taking this opportunity, we decided to re-verify the material that emits infrared rays at normal temperatures.

We conducted the verification through a double blind test similarly to the verification of mid-alpha waves. As a result, there were no conspicuous changes in the temperature of the fundus of the eyes when using the simulated material, but it was revealed that the temperature increases by approximately 1 °C when using the material that emits infrared rays at normal temperatures.
