【英语时差8,16】微笑有助于健康（上）

（单词翻译）

I've heard that laughing provides the same health benefits as jogging or some other type of light workout. Is this true? Funny you should ask, because a study out of Loma Linda University in California found that mirthful laughter is in fact very healthy. It lowers stress, boosts the immune system, and can lower cholesterol¹ and blood pressure. To go into a little more detail, other studies have found that laughing has a positive effect on the inner lining² of blood vessels³, called the endothelium.
