Scientific research shows that in addition to the hunger signal sent by the body because of nutritional needs, environmental factors such as music and light will also affect people's appetite.
1. Soothing classical music and light music can stimulate appetite and help digestion. Wang Guorong pointed out that good music can relax emotions, and relaxed emotions can act on the hypothalamus of the human body, thus promoting appetite. Moreover, music, as an art of time, can make the hurried modern people slow down and have a good taste of food. For example, Mozart's sonata K 448 for two pianos in D major has been proved by scientists to be a classic piece to improve mood. On the contrary, loud and fast-paced concerts make people unwilling to eat. In addition, American research points out that music with beautiful melody and slow rhythm can increase gastrointestinal peristalsis and digestive gland secretion, which is helpful for digestion. Therefore, you can listen to soothing music during and after meals, especially for the elderly.
2. brightly colored tableware makes people eat well. A study by Boston University in the United States showed that using brightly colored tableware can increase the diet of Alzheimer's patients by more than 25%. Bright food or environment (red, yellow, orange, etc. ) can stimulate people's central nervous system from the senses and make people's appetite increase greatly. On the contrary, dark colors, such as gray and black, will reduce the excitement of eating.
3. The lights are bright. The intensity of light has a certain relationship with the secretion of dopamine in the brain. The light intensity when the sun just comes out can be used as a passing line, and bright light can greatly increase people's appetite. Therefore, if you eat at home, try to make the room brighter, but when you eat in a restaurant outside, the light is not too bright. Studies have found that in public places like restaurants, poor light makes people eat more comfortably.
