“…24 Heart rate is a physiological indicator used to control the feedback signal. 25,26 The main indicator of the experiment expressed in beats per minute (BPM). Slow breathing is related to relaxation, while irregular rapid changes or cessation of breathing correspond to higher stimulation levels.…”

An experiment based on physiological parameters and subjective emotional changes is designed to analyze the sound‐light fusion effects. The different effects caused by music in major and minor keys is studied. Three colorful lighting with main wavelength at 623, 537, 445 nm, respectively, as well as two white lighting with 3000 K CCT and 6000 K CCT are evaluated in the same process. Results show that the physiological response to music is stronger than that of the lighting stimulus. Music plays a major role in the sound‐light fusion environment, and the physiological perception under dual‐factor stimulation is stronger than that of single factor. Moreover, music and light interact with each other when they stimulate emotions at the same time. The superposition of two positively related factors can strengthen the effects on emotion. The studies may give suggestions to the designers when they design a lighting show with music or an immersive and interactive lighting project.

Patients in the ICU are exposed to 24 hours of light exposure to abnormally low light levels during the day and constant light disturbances throughout the night. Prolonged abnormal light exposure can impact the circadian rhythm, which may indirectly affect the patient's physiological condition. This literature review aims to determine the effect of light exposure on the physiological condition of patients in the ICU, including heart rate, mean arterial pressure (MAP), body temperature and sleep quality and offer possible alternative options. Qualitative synthesis by collecting research articles for the last five years from Google Scholar, Science Direct, Scopus, Medline, CINAHL, PubMed, and ProQuest. There were 5 international journals with experimental and observational research designs. Abnormal light exposure in the ICU has an effect on increasing the heart rate and decreasing the quality of sleep of the patient. Compared to a decrease in nighttime light levels, an increase in artificial light during the day may be more promising to support the improvement of the patient's physiological condition.
