For those who prefer to travel light and keep everything in their pockets, there's some bad news.

    If your wallet is jam-packed with old receipts, coupons - maybe even a bit of money - it might be time to invest in either a man bag, a handbag or a sturdy rucksack.

    The reason is: Keeping your wallet in your back pocket is putting you at risk.

    But this time, it's not about being an easy target for pick-pockets, although you should be wary of them too.

    New York City-based chiropractor Dr. Arnie Angrist warned keeping a "fat wallet" in your back pocket is doing your back, hips, neck, pelvis and even your bottom potentially a lot of harm.

    How?

    The doctor explained how sitting on a wallet "creates an asymmetry or imbalance that distorts your pelvis and hips."

    Having one hip sat higher than the other causes the back and neck to compensate for the unevenness, which in turn can lead to problems in these areas.

    But that's not all.

    A professor of clinical sciences at University of Bridgeport College of Chiropractic, Dr. Chris Good also bore more bad news.

    He explained how sitting on a wallet can cause the spine to become tilted, or for the body to compensate for the tilt.

    Over time, this could lead to serious problems for spinal joints, muscles and discs, resulting in serious pain and even failure.

    As for our posteriors, according to Dr. Good, a wallet in a back pocket "could cause irritation to a number of important structures in the buttocks" including damage to nerves, muscles, arteries and veins.

    为什么不要把钱包放在后口袋

    那些喜欢轻装上路、把所有东西都塞在口袋里的人，有个坏消息你们得听听。

    如果你的钱包被旧收据和各种优惠券塞得鼓鼓的，甚至还装了点钞票，那么是时候给自己买一个男士手提包或是一个结实的背包了。

    原因是，把钱包放在你的后口袋里会让你陷入风险。

    不过这次，我们要说的不是你会很容易变成扒手的目标，尽管你也得防着他们。

    在纽约工作的脊椎按摩师阿尼?安格瑞斯特医生警告说，把鼓鼓的钱包放在后口袋里将对你的后背、髋部、颈部、骨盆甚至臀部造成很多潜在危害。

    危害如何产生？

    这名医生解释说，坐在钱包上“产生的不对称性会扭曲你的骨盆和髋部”。

    一半屁股坐得比另一半高导致后背和颈部相应地扭曲来弥补这种不平衡，从而导致这些部位也出现问题。

    但这并不是全部。

    桥港大学脊骨神经医学院临床科学系的教授克里斯?古德医生也带来了一些坏消息。

    他解释了坐在钱包上如何会导致脊柱倾斜，或者让身体其他部位来平衡这一倾斜。

    时间久了，这将会导致脊柱关节、肌肉和椎间盘产生严重问题，最终导致严重的疼痛甚至行动困难。

    古德医生指出，至于我们的臀部，放在后口袋的钱包“将会刺激臀部的多个重要组织”，例如对神经、肌肉、动脉和静脉造成损伤。
