Do you need an energising blast of water in the morning to wake you up for the day? Or do you prefer a relaxing, warm shower in the evening to help you wind down as part of your nighttime routine? Maybe you just shower whenever you feel like it. For something so many of us do, this topic is bound to divide opinion and stir up passion from both sides. But is one really better than the other?您早上需要充满活力的水才能唤醒您一天吗？ 还是您喜欢晚上放松，温暖的淋浴，以帮助您作为夜间例行的一部分放松身心？ 也许只要您觉得，就可以洗澡。 对于我们许多人所做的事情，这个话题必定会分裂意见并激发双方的激情。 但是一个真的比另一个更好吗？

After a long day in the outside world, picking up pollutants and allergens on your skin and in your hair such as dust and pollen, a reasonable instinct would be to wash it all off before getting into bed. That's what the evening shower enthusiasts would say. But, says microbiologist Primrose Freestone, no matter the air temperature, you will continue to sweat during the night. Bacteria on your skin then eat the nutrients in your sweat which is what causes BO. Showering at night also doesn't stop you shedding dead skin cells. All this means you may not wake up feeling as fresh as you had hoped. Showering in the morning, on the other hand, can help to remove dead skin cells, sweat or any bacteria you've picked up from your bed sheets. "As a microbiologist, I am a day shower advocate," she says.在外界漫长的一天之后，在您的皮肤和头发上捡起污染物和过敏原（例如灰尘和花粉），合理的本能是在上床睡觉之前将其全部洗净。 这就是晚间淋浴爱好者会说的。 但是，微生物学家培养馆说，无论空气温度如何，您都会在夜间继续出汗。 皮肤上的细菌然后吃汗水中的养分，这是导致BO的原因。 晚上淋浴也不会阻止您脱落死皮细胞。 这意味着您可能不会像您希望的那样醒来。 另一方面，早晨淋浴可以帮助清除死皮细胞，汗水或您从床单上捡起的任何细菌。 她说：“作为一名微生物学家，我是一日淋浴的拥护者。”

But it's not all about cleanliness. Nancy Rothstein, who calls herself The Sleep Ambassador, is concerned with sleep quality. In her view, showering in the evening is an essential part of the 'preparing for bed' routine. "Call it an opportunity to shower yourself with mindfulness," she says. And research backs this up. A systematic review of research published in Sleep Medicine Reviews in 2019 found nightly warm showering or bathing one to two hours before bedtime can improve sleep.但这并不是全部关于清洁度。 南希·罗斯斯坦（Nancy Rothstein）称自己为睡眠大使，他关心睡眠质量。 在她看来，晚上洗澡是“准备床”例行的重要组成部分。 她说：“称其为正念洗澡的机会。” 并研究了这一点。 对2019年睡眠医学评论发表在《睡眠医学评论》上的研究的系统评价发现，每晚暖淋浴或在睡前沐浴一到两个小时可以改善睡眠。

What it all boils down to is when you would like to feel freshest. If you're someone who can't fully relax in bed until you've showered, you're likely an evening shower person. Whereas, if you can't stand the idea of putting on fresh, clean clothes in the morning when you haven't showered, then a morning rinse is probably more your style. Whenever you choose to shower, Primrose Freestone says it's important to clean your bed sheets regularly to remove all the sweat, bacteria and dead skin cells that build up and can negatively affect the effectiveness of your showers.这一切都归结为当您想感到最新鲜时。 如果您是一个不能在洗澡之前完全放松的人，那么您可能是一个晚间淋浴的人。 鉴于，如果您不能忍受在没有洗澡时早上穿新鲜，干净的衣服的想法，那么早晨的冲洗可能是您的风格。 每当您选择淋浴时，Primrose Freestone都说，定期清洁床单以清除堆积的所有汗水，细菌和死皮细胞，并可能对淋浴的有效性产生负面影响。
