【英语时差8,16】微笑有助于健康（下）

（单词翻译）

When we laugh, blood vessels¹ relax and become more pliable², making it easier for blood to flow. Plus, laughter is a good stress reliever. That’s important because stress is known to harden arteries³. Laughter is even good for digestion⁴. If you’re eating with friendly people who are having a good time, you’re much less likely to need an antacid pill afterward⁵. Bottom line, laughter is good for you. In fact, experts recommend that alongside eating well and exercising, people should laugh for at least fifteen minutes a day. But not necessarily by hearing jokes. After all, even the funniest jokes make you laugh for only a few seconds. The best way to laugh is to be around people who make you laugh, at work or at home or wherever.
