fight off sth.中等

If we adults could indulge in a bit of silliness and giggling, we would reduce the stress hormones in our bodies, increase good hormones like endorphins, improve blood flow to our hearts and even have a greater chance of fighting off infection.

如果我们成年人能放纵自己犯点傻、咯咯笑一笑，就能减少体内的压力激素，增加内啡肽等有益激素，改善心脏的血液流动，甚至更有可能抵御感染。
