• The Idea to demonstrate the advantages of the building material
wood with a study project

Results of the pine study:
• Significant reduction in cardiac workload after sleeping in a bed made
from pine wood (3,500 heartbeats / night)
• Lasting positive effect also noticeable during daytime
Relevant previous projects: Pine study

Results of the spruce study:
• Significant advantages of the spruce room regarding
HRV-parameters and heart rate in 25.6 % of the test phases
• Lower stress level in the spruce room, especially in the relax phase
and after power nap
• Significant advantages of the spruce room under conditions of
stress (mental stress was perceived less strenuous)
Relevant previous projects: Spruce study

• Heart rate:
... in awake state; decreases in "Wood classroom" group (test
group) but increases in "Standard classroom" group (control
group)
• Vagus nerve activity (cardioprotective value):
... in awake state, increases in test group but decreases in
control group
... during night time; remains unchanged in test group but
decreases in control group
• Social stress of pupils caused by teachers:
... remains unchanged in test group but increases in
control group
• School performance and concentration skills:
... less mistakes due to lack of concentration in test group

Effects of the results on other fields

What do these results mean for the
education sector?
• Proof that schools made from wood provide a stress-free
environment for pupils and teachers:
- Less aggression among pupils
- More willingness to learn and less mistakes due to lack of
concentration and / or focus
- Higher teaching quality due to less behavioural problems
- Probably reduced burnout risk for pupils and teachers
