在炎热的夏天里，合理安排作息时间和选择适当的服装来保护皮肤免受紫外线的伤害至关重要。以下是一些建议，可以帮助您制定一份有效的夏季养生作息时间表，以及确定何时适合穿上防晒衣。

早晨（日出到上午10点）

清晨是一天中紫外线辐射较弱的时间段之一。如果您的户外活动较少，可以选择在这个时候做一些轻松的活动，如散步或慢跑，但仍然需要注意防晒措施。避免长时间暴露在阳光下，因为随着太阳逐渐升高，紫外线强度也会增加。

日间（上午10点至下午2点）

这段时间是紫外线最强烈的时候，因此应尽量减少外出和室外活动。如果您必须在这段时间外出，请务必做好充分的防护措施，包括戴上宽边帽、太阳镜，涂抹SPF30以上的广谱防晒霜，并且穿长袖衬衫和裤子等衣物来遮挡皮肤。同时，寻找阴凉的地方休息，比如树荫下或者有遮阳的建筑物的阴影处。

午后（下午2点至日落前）

下午晚些时候，紫外线的强度会略有下降，但仍需注意防晒。这个时间段可以适当地进行户外活动，但同样要做好防晒工作。此外，由于温度较高，身体水分流失较快，要注意补充足够的水分，保持身体水平衡。

日落后（日落到晚上9点左右）

夜晚是紫外线辐射最低的时刻，您可以放心地享受户外的休闲时光。不过，夜间人们行走时应注意道路是否平坦及有无障碍物，在没有路灯的道路上小心慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎
