Description
The aim of this study is to investigate the physiological stress effects of light colour on white and coloured LED lighting in the elderly people. The laboratory experiment was conducted on 19 elderly subjects and analysed using heart rate variability. The results showed that the 2700 K and 6500 K conditions, which significantly decreased HR and significantly increased HF, were considered to be relaxing tendencies. Based on the experimental results of previous studies, comparisons with young age groups showed that there were no differences in tendency according to light colour between age groups, but that the tendency to relax may be weakened in elderly people.
