运动与健身
Scenario: Many of us choose the summer to get rid of extra weight for a slimmer figure. But working up a sweat in the sun can compromise the protection offered by sunscreen.
适用情境：大多数人都会选择在夏天减肥，让身材更加苗条，不过，在阳光下大量流汗会减弱防晒霜的防晒效果。
SPF requirement: 45 or more
防晒系数: ≥45
Solution: Sunscreen with SPF of 45 and a water-resistant formula is strongly recommended. You can also look specifically for sunscreens made for athletes, such as a non-greasy spray that is not only convenient to carry with you, but also dries quickly so that it won’t run into your eyes. However, a water-resistant sunscreen cannot maintain its SPF very long when you are sweating, so you had better reapply it every 40 minutes.
防晒建议：这种情况下，强烈推荐防晒系数45并且含有防水配方的防晒霜。你可以专门关注运动员专用的防晒霜，例如非油性喷雾，它不仅便于携带而且干得很快，不会流进眼睛。但是，当你流汗时，防水性防晒霜的防晒时间会大打折扣，所以最好每40分钟重涂一次。
