Blue lighting accelerates post-stress relaxation: Results of a preliminary study
Researchers at the University of Granada subjected participants to short-term (acute) social stresses similar to having to meet a deadline for work or having a holiday dinner with family. The results demonstrated that after acute stress blue light accelerates relaxation compared to normal white light.
After performing a stressful task, participants were sent to lie down in rooms with either blue or standard white light. For the test group, the relaxation time was approximately three times faster than for the control group.
