Tip-offs give athletes time to dilute their blood, or to wait for microdosed drugs to clear their bodies.

这让运动员有时间稀释血液，或者等待微剂量药物清理身体。

When I drink a glass of water and that water is absorbed into my blood, my plasma osmolality drops, which means I'm diluting my blood with the water.

当我们饮用一杯水后，水分吸收至血液中，血浆渗透压降低，意味着血液被稀释。
