A combination of meditation and skin conductance plus skin temperature biofeedback reduces stress and depression more than meditation alone or routine nursing in people with diabetes and mild depression. A randomized controlled trial with 102 participants divided into three groups of 34 found statistically significant differences among the groups, with the combined intervention producing the greatest reduction in the linear combination of stress and depression measured by the Symptoms of Stress Inventory and Beck Depression Inventory. The biofeedback program helps people learn to relax by feeding information back through on-screen visual signals.
An eight-week daily practice of deep breathing and body scan meditation combined with music improved sleep quality and quality of life in older adults with poor sleep. The intervention group showed a significant decrease in global PSQI scores and an increase in PTQL scores, while the control group showed no change. Among PSQI components, daily disturbance improved significantly more than in controls, though sleep efficiency and perceived sleep quality did not differ between groups. PTQL domains all improved except the economic domain. The authors conclude that this combined intervention positively affects sleep and quality of life in older adults.
