EEG under black light

Verification of the physiological mechanism of Snoezelen

Abstract

In recent years, many modern people are required to be able to adapt quickly to diverse social situations. In practice, however, it is often the case that people are unable to adapt immediately to rapidly changing environments, resulting in a maladaptive state.

Until now, measures have been sought to address various issues such as developmental disabilities and support for ageing societies, etc. One facility that is expected to improve the situation is the Snoezelen, which originated in the Netherlands. Snoezelen is generally referred to as a facility with a multi-sensory environment and was started as a recreational activity for severely mentally handicapped people. In recent years, however, the Snoezelen has been used for a broader range of purposes and has proven to be successful. However, the clear mechanism of the effect has not been clarified. Therefore, this study focused on the black light used as snooze lens equipment and conducted EEG measurements to verify the physiological mechanism. The results showed that, although there were individual differences, changes in the appearance rate of δ, θ and β - waves were observed even under black light illumination.
