Happiness increases when we experience more positive emotions throughout the day. Fredrickson, a leader in the field of psychology, identifies 10 positive emotions, including joy, interest, hope, pride, amusement, inspiration, love and so on. How often we experience these positive emotions compared to negative emotions in a day affects not only our mood, but also our physical health. He has discovered that those who have a 3∶1 ratio of positive to negative emotions on a daily basis are happier and healthier.
Sadly, most people, even those who consider themselves positive people, are far below that ratio. The good news is that you can learn to increase your ratio of being positive, which leads to greater happiness, health and success.
Research shows that by increasing positive emotions, we become more creative, perform better at tasks, and have better relationships. The most exciting finding is that we now have proof that selfgenerated positive emotions can improve our physical health.
Nevertheless, we don’t want to get rid of all negative feelings. Negative emotions are proper and helpful sometimes. It’s appropriate to feel sad about the loss of a loved one. Anger often pushes us into action to improve a situation or correct a mistake. However, if you find yourself waiting impatiently when the driver in front of you doesn’t instantly notice the light turns green, or if you find yourself scolding your kids for laughing too loud while you are on the phone, you are having negative feelings in your daily life too often. Then you should step back and analyze those feelings, and turn them around.
【解题导语】 研究表明：积极的情感不仅能增加幸福感，而且对身体健康也有好处。但是负面的情绪也并非一无是处，有时候也会起帮助作用。所以我们要学会调控自己的心情。
