Research On The Restorative Effects Of Plant Color On Human Physiology And Psychology

As urbanization continues to accelerate,"health" has become a major concern for the public.In the face of the high pressure and fast pace of urban life,health problems caused by stress have become the cause of most diseases,and the long-term accumulation of anxiety without timely regulation increases the chances of hypertension,depression and mental subhealth conditions.The long-term accumulation of anxiety without timely regulation increases the chance of hypertension,depression and mental subhealth conditions.Many studies have analyzed and compared the differences between artificial and natural environments on health effects,and more specific restorative studies on landscape elements have gradually become the focus of research,but previous empirical studies on plant color are mostly single color,and the study of plant combination color is still at a relatively preliminary stage of exploration,so this paper takes typical garden plant flower color as the research object,and firstly researches the common colors of garden plants Finally,using a combination of subjective and objective research methods,we tested the effects of different single plant colors and combined plant colors(contrast,proportion,and color distribution)on the subjects’ indicators by using an eye-tracking device and physiological testing instruments and psychological scales,and compared the data for analysis.The results afterwards were as follows:(1)The results of single-flower color experiments showed that red and purple flowers were the most pleasant;yellow and red flowers had better stress-relieving effects than other flower colors;white and blue flowers had stronger tension-relieving effects;blue and purple flowers had the best effect on attention and cognitive level recovery.(2)The experimental results of different contrast color combinations showed that the180° contrast color combination was the most exciting and had the best effect on stress relief,while the 30° contrast color combination had a stronger effect on tension relief and cognitive recovery;the softer the contrast color combination was,the higher the benefit on the subjects’ psychological recovery.(3)The experimental results of different proportion of color combinations showed that the physiological relief of stress and tension was stronger when the proportion of two contrasting colors in the color combination was balanced,and the effect on psychological recovery was also better;the change of color proportion had a significant effect on the recovery of attention,among which,the recovery of subjective attention was stronger when the proportion of cool or dark colors was larger.(4)The experimental results of different color distribution methods showed that each group of pictures had positive effects on subjects’ physiology and psychology,and the interaction between plant color contrast and color distribution method had significant effects on psychological recovery scores.By scientifically applying the findings of all plant color studies to different needs,we can help create a healthy landscape with the most positive effect on public health.
