Changes of light intensity of different colors can shift many physiological parameters and conditions like melatonin, alertness, body temperature, heart rate (HR), and heart rate variability (HRV). The aim of this pilot study was to investigate acute temperature, HR, HRV, and state of mind reactivities after illumination with red (631 nm) and blue (456 nm) light (illuminance 140 lux for both). Seven healthy volunteers (5 females, 2 males; mean age ± SD 34.1 ± 11.9 years) were investigated at the Medical University of Graz, using new color light panels. Significant decreases were found only after 10 min blue light stimulation in nose temperature (P=0.046), HR (P<0.05), and total HRV (P=0.029), in association with a significant alteration of the emotional state (stress level score,P=0.006). However, red light stimulation of the same persons did not induce the same effects in these parameters. The effect of blue light as environmental stimulation on human health is not clarified in detail and needs further investigations.

Recent evidence shows that both music therapy and resonance breathing (breathing at about 0.1 Hz) may be effective in treating stress-related symptoms and promoting relaxation. However, no study has yet explored the potential of integrating the working mechanisms into a combined approach using live played music to guide respiration. Therefore, the objective of the present pilot study was to evaluate the psychophysiological effects of a combined intervention. A total of 60 healthy adults were randomized to either the experimental group or the control group (where participants listened to prerecorded relaxation music). Heart rate and heart rate variability were extracted for the following 5-minute segments: Resting baseline, stress task, intervention, resting post-intervention. Additionally, self-evaluation scores for relaxation and general well-being were assessed with visual analogue scales. Significant time × group interaction effects were found for general well-being (p = .028) and heart rate variability as measured by RMSSD (p < .001), indicative of increased parasympathetic outflow in the experimental group. In conclusion, the combination of music therapy and resonance breathing seems to be a well-received and effective way to induce relaxation and well-being in healthy adults.

Abstract Background Cardiovascular disease is one of the leading causes of death globally with hypertension being a primary cause of premature death from this disease process. Individuals with a family history of cardiovascular disease and hypertension are at a greater risk for developing the same sequela. Autonomic cardiac control is important in the level of cardiac function. One intervention that is effective in improving cardiovascular function is heart rate variability biofeedback training. The purpose of our study was to determine the effectiveness of heart rate biofeedback training on HRV and blood pressure in individuals with a family history of cardiovascular disease. Methods Thirty-four participants (76.5% female, 22.7 ± 4.3 years) completed a baseline assessment and training using an established short-term HRV protocol followed by two weeks of at-home paced breathing employing a smartphone application. The participants were then reassessed in a biofeedback clinic. Results The participants physiological measures showed a significant increase in means between pre and post intervention of SDNN (t (32) = 2.177, p =.037) and TP, (t (32) = 2.327 p = .026). Correlation noted a medium effect on diastolic blood pressure and high frequency heart rate variability, F, r = .41, n =33, p < .05. A multiple regression with all predictor variables in the model found no significance with diastolic and systolic blood pressure. Conclusions The findings from this pilot study demonstrated that a two-week paced breathing intervention may assist in reducing heart rate and diastolic blood pressure while improving heart rate variability.
