[对应学生用书第1页] The benefits of smiling and laughing 1．Neurotransmitters(神经递质)called endorphins(内啡肽)are released when you smile. These are triggered by the movements of the muscles in your face, which is interpreted by your brain, which in turn releases these chemicals.Endorphins are responsible for making us feel happy, and they also help lower stress levels.The more we stimulate our brain to release this chemical, the more often we feel happier and relaxed． 2．Endorphins make us feel happier and less stressed． They also act as the body's natural pain killers.For sufferers of chronic pain, laughing and smiling can be very effective in pain management. 3．While the release of endorphins is increased, the stress hormone cortisol(激素皮质醇)is reduced． Cortisol is more active when we feel stressed or anxious and contributes to the unpleasant feelings we experience, and by lowering it we can reduce these negative feelings. 4．Laughing expands the lungs, stretches the muscles in the body and stimulates homeostasis(体内平衡). This exercises the body, replenishing the cells from a lungful of oxygen and gaining all the benefits of exercising the body. 5．A good laugh can be an effective way to release emotions. A good laugh can help you release emotions, especially those emotions that you might bottle up inside.Everything looks that little bit better after a good laugh and life can be seen from a more positive perspective.Smiling and laughing have positive social influences as well. 6．Smiling is an attractive expression, which is more likely to draw people to you rather than push them away. Smiling makes you appear more approachable.Interaction with others is easier and more enjoyable when smiles and laughs are shared, and these behaviours are contagious, making others feel better too, and make you a more appealing and attractive person to be around． 7．A happy, positive expression will serve you well in life. This is particularly true for challenging situations such as job interviews: a smiling, relaxed person indicates confidence and an ability to cope well in stressful situations. 1．interpret v.　　　　　 解释， 说明 2．stimulate v. 刺激 3．contribute to 促使 4．bottle up inside 憋在心里 5．contagious adj. 有传染性的 How can we smile and laugh more often?
