What effect does color have on human health?

People often combine colors with human feelings and emotions and divide them into warm colors and cool colors. Warm colors include red, orange, yellow and red, while cool colors are mainly blue, white, green, purple and black. Red represents enthusiasm, and it excites you when you look at it, so when people are faced with failure and depression, try to create a red world for themselves. On the contrary, if people are angry and anxious, they should try to avoid red to avoid adding fuel to the fire. Therefore, people with high blood pressure and cardiovascular diseases should try not to miss the red color. Yellow is also a warm color, but it is weak. Generally, it is not appropriate to look yellow in front of mental patients when you are upset. Grass green or green is cool, calm and peaceful. When people are placed in a green environment, their pulse slows down, their breathing is stable, their body temperature drops by 1~2 degrees Celsius, and they are open-minded and open-minded, which is very conducive to self-cultivation. No wonder people build hospitals and sanatoriums between green mountains and clear waters, with flowers and trees in the hospital, light green indoor walls and bonsai flowers in front of the bed.
