Ways to improve your mental health

改善心理健康的方法

Start volunteering

开始志愿服务

A prayer attributed to St. Francis of Assisi tell us, "It is in giving that we receive."

阿西西圣方济各的一段祷文告诉我们:“我们在给予中获得。”

Turns out he was scientifically right. Studies have shown that putting the well-being of others before our own without expecting anything in return, or what is called being altruistic, stimulates the reward centers of the brain. Those feel-good chemicals flood our system, producing a sort of "helper's high."

事实证明他在科学上是正确的。研究表明，将他人的幸福置于自己的幸福之上而不期望任何回报，或者称为利他主义，会刺激大脑的奖励中心。那些感觉良好的化学物质充斥着我们的系统，产生一种“帮助者的快感”。

There are physical benefits, too: Studies show volunteering minimizes stress and improves depression. It can reduce the risk for cognitive impairment. It can even help us live longer.

这对身体也有好处:研究表明，志愿活动可以将压力降至最低，改善抑郁。它可以降低认知障碍的风险。它甚至可以帮助我们活得更久。
