Human physiological responses to wooden indoor environment

Area of Science:

• Environmental Psychology
• Human Physiology
• Building Science

Background:

• Limited research exists on the physiological effects of wooden indoor environments.
• Previous studies primarily focused on non-wooden settings, leaving a gap in understanding wood's impact.
• The influence of wooden interiors on human physiology remains largely unexplored.

Purpose of the Study:

• To investigate distinct physiological responses to wooden versus non-wooden indoor environments.
• To assess how different indoor materials affect occupant well-being and physiological markers.
• To provide empirical evidence on the benefits of wooden environments for indoor occupants.

Main Methods:

• Physiological parameters including blood pressure, electrocardiogram (ECG), electro-dermal activity (EDA), oxyhemoglobin saturation, skin temperature, and near vision were measured.
• Twenty healthy adults participated in a 90-minute experimental investigation.
• Comparative analysis of physiological data collected in wooden and non-wooden indoor settings.

Main Results:

• Participants experienced less tension and fatigue in wooden rooms compared to non-wooden rooms during work tasks.
• Wooden environments demonstrated positive effects on the autonomic nervous system, respiratory system, and visual system.
• Significant improvements in physiological regulation and ease of function were observed in wooden settings, particularly after sustained work.

Conclusions:

• Wooden indoor environments offer greater physiological benefits than non-wooden environments.
• Exposure to wooden interiors positively influences key physiological systems, enhancing occupant well-being.
• The findings support the integration of wooden elements in indoor design for improved health and comfort.
