In America, when you go without wearing any underwear, we jokingly call it "going commando." If you've ever deployed to a joint military base and you've worked alongside Royal Marines, then you understand the term better than most — you've probably received an uncalled-for eyeful when these troops wake up for the work day. That's because they tend to sleep in just their birthday suits.
But it's not for comfort's sake — it's hygienically sound.
It's no secret that, when the mission calls for it, military personnel sometimes have to live in tight berthing areas. Because of this close-quarter living, illnesses and bacteria can quickly spread from person to person.
Most service members are taught to shower before they go to bed. After all, you want to remain as clean as possible throughout the night. But when we sleep, we naturally sweat from our pores. Meanwhile, our microscopic skin cells die and flake off. You might not know it, but you leave behind an imprint of skin and sweat wherever you lay — it's actually pretty nasty.
Royal Marines tend to sleep naked so they don't hold all the juices and skin flakes emitted from their bodies in the clothes they'll later wear.
U.S. troops are taught to sleep in a t-shirt and undies or some type of pajamas. Sure, this might contribute to the ever-growing pile of dirty laundry, but at least it's easier to go to the restroom at 0300 — which is located on the other side of the FOB.
Sleeping naked may work for our Royal Marine allies, but U.S. military culture hasn't accepted the idea — yet.
