Conditions

Autonomic Nervous System Imbalance, Emotions, Physical Activity

Brief summary

Light influences on human movement, autonomic nervous system, and emotion. It is inconclusive whether illuminance (Ev) and colour temperature (Tc) is appropriate to human movement, autonomic nervous systme, and emotion. Effect of Ev and Tc on responses of movement, autonomic nervous system, and emotion in human is investigated.

Detailed description

The adult and elderly sign informed consent form. They sit in a room where Ev and Tc is adjusted. During sitting they are measured response of movement, autonomic nervous system, and emotion.
