Laughter are healthier and happier.
爱笑的人更健康快乐。
They have improved respiratory health.
改善呼吸健康
Laughter flushes the lungs with fresh air and helps you breathe more deeply. People who love to laugh inadvertently stretch their lungs, increase their heart rate and reinvigorate their entire body when laughing. This is equal to a splash of cool, fresh, rejuvenating water for the respiratory system.
笑有利于肺部吸入新鲜的氧气，有利于我们进行深呼吸。当爱笑的人在笑的时候，他们的肺部扩张，心率增加，全身恢复精力。这就相当于给我们的呼吸系统来了一瓶干净酷爽的回春水。
They have lower chances of heart disease.
远离心脏病
A study conducted at The University of Maryland found that there is a link between laughter and cardiovascular health. Laughter causes the tissue that composes the lining of blood vessels to expand, allowing for better blood flow. In other words, people who love to laugh improve the function of their blood vessels and increase blood flow. This helps protect their heart from diseases.
马里兰大学的一项研究发现笑和心血管健康之间存在着联系。笑会导致血管内壁组织扩大，有利于血液充分流动。换句话说，爱笑的人可以改善血管的功能，增加血流量。这有助于他们远离心脏病。
