让我们停止这种有损无益的竞争吧。

Let's end the wasteful competition.

忏悔可能对灵魂有好处，但对声誉则有损无益。

Confessions may be good for the soul but they are bad for the reputation.

此外，长时间的风吹日晒及反复“日光浴”对老年人的皮肤养护有损无益，应尽可能避免。

In addition, the prolonged and repeated wind and sun, "sun" on the skin and conservation to the detriment of older persons, should be avoided.
