It’s one of those old wives tales that, to this day, remains an area of contention. Will wearing your bra to bed help keep your breasts nice and perky?

如今，有个传统的说法饱受争议。睡觉时不摘文胸真得能让乳房更加挺拔傲人吗?

Marilyn Monroe swore by it, but others find it uncomfortable and really, and who can blame them?

玛丽莲·梦露就穿着文胸入睡，其他女人却觉得这很不舒服，可谁又能怪她们呢?

But, painful straps and wires aside, Dr Seth Rankin says sleeping in your bra could actually be bad for your health.

医生赛斯·兰金说，事实上，难受的背带和钢圈会使穿着文胸睡觉对身体有害。

Not only does he insist that it will have little-to-no impact on your breasts heading south, but he also suggests that the garment could restrict the lymph glands.

他不仅强调这样做对防止乳房下垂毫无作用，还指出内衣会压迫淋巴腺。

“When you're lying down flat, the effect of gravity pushes the breast tissue back towards your chest, instead of down towards your toes,” he told Cosmopolitan.

“当你平躺时，重力作用会把乳房组织往胸部方向推，而不是朝脚趾方向垂。”他告诉《时尚COSMO》杂志。

“So wearing a bra (the purpose of which is ultimately to support breasts from below) is essentially redundant in bed, as breasts naturally compress back down onto the chest.”

“所以戴着文胸(最终目的是支撑乳房以防下垂)上床睡觉实际是多余的，因为乳房自身能垂直地朝胸部压。”

It might not have any impact on sustaining youthful, gravity defying breasts but it’s not doing any harm, right?

所以睡觉不摘文胸可能无法让胸部保持年轻、不下垂，但也没有什么坏处，是吗?

Wrong. Dr Rankin goes on to explain that, wearing a bra to bed can affect the lymph glands.

错。兰金医生接着解释说，穿文胸睡觉会对淋巴腺有害。

“A tight bra may restrict the flow of lymph to the many important lymph nodes around the breast and armpit, hindering the system's vital function of flushing toxic waste-products from the body,” he adds.

“过紧的文胸会使淋巴循环不通畅，对大量位于乳房和腋下的重要淋巴腺体不利，阻碍了淋巴系统的排毒功能正常运转。”他补充说。

Other experts have confirmed this too. Speaking to the Mail, Professor Mokbel warned women about the dangers of wearing ill-fitting bras.

其他专家也肯定了这点。穆克比勒教授在接受《邮报》的采访时，警告了女人穿着不合身文胸的危害。

“Wearing a constrictive bra to sleep affects the physiology of the breast,” he said.

“穿束紧的文胸睡觉会破坏胸部的生理机能，”他说。

“It can impair the blood flow and lymphatic drainage, which, at worst, can lead to chronic inflammation, oedema (fluid retention) and discomfort.”

“它会阻碍血液循环和淋液流动，最坏的情况甚至会导致慢性炎症，水肿(液体淤留)和疼痛。”
