Autonomic function indices of heart rate variability at sitting rest and during psychomotor workload under the two types of combined lighting. Data are least-square means and the standard errors of the means (error bars) adjusted for the effects of experimental order. Low-low = low-CCT (4500 K) ambient lighting+ low-CCT (5000 K) task lighting; high-low = blue-enriched high-CCT (12000 K) ambient lighting + low-CCT (5000 K) task lighting. *P <0.05 and **P <0.01: The significance of difference between the low-low and high-low combined lightings within each age group
