Walk into any hospital and you’ll see a sea of solid blues, greens, and maybe some obnoxious holiday prints. It’s the standard. But if you stop and think about it, why do healthcare workers wear scrubs anyway? It wasn't always this way. If you look at old photos from the early 1900s, surgeons actually wore their own street clothes—maybe with a butcher’s apron if they were feeling fancy. Honestly, it was pretty gross.
The shift didn't happen because of a fashion trend. It happened because people started realizing that germs were real.
Today, scrubs are basically a high-tech tool. They aren't just pajamas that are socially acceptable to wear in public. They serve a bunch of specific functions from infection control to helping a nurse not lose their mind during a 12-hour shift.
The Bloody History of Hospital Gear
Before the mid-20th century, surgery was a mess. There was this weird "badge of honor" thing where surgeons would wear their blood-stained coats to show how many procedures they'd done. It’s hard to imagine now, but the idea of "sterile" was a slow burn in the medical community.
When the Spanish Flu hit in 1918, things changed. Doctors started wearing masks. Then, in the 1940s, we got the first version of "surgical greens." They picked green because the bright white of the old drapes and clothes, combined with the intense operating room lights, caused massive eye strain and "afterimages" for surgeons. If you’ve ever looked at a bright light and then seen a ghost-spot on the wall, you get it. Green or teal neutralizes that effect.
By the 1970s, the scrub suit we recognize today—v-neck top, drawstring pants—became the gold standard for almost everyone in the building.
Why Do Healthcare Workers Wear Scrubs for Infection Control?
This is the big one. Cross-contamination is the enemy.
Scrubs are designed to be "lint-free" and easy to clean. Think about the fabric. Most modern scrubs, like the ones made by FIGS or Cherokee, use a blend of polyester, rayon, and spandex. They’re treated with antimicrobial finishes sometimes, but the real benefit is the washing process.
The Heat Factor
Healthcare facilities use industrial-grade laundry services. These machines get way hotter than your home washer. If a nurse wore their favorite cotton t-shirt to work and got hit with a "code brown" or a splash of blood, that shirt is basically ruined. Scrubs are built to withstand high-heat sterilization and harsh chemicals without falling apart.

Identification and Safety
You’ve probably noticed different colors in different departments. It’s not just for aesthetics. Many hospitals use color-coding to identify who does what.
- Navy Blue: Often nurses.
- Royal Blue: Sometimes respiratory therapists.
- Dark Grey: Often technicians or X-ray staff.
- Maroon/Burgundy: Frequently seen on phlebotomists.
This helps in a crisis. If someone stops breathing in a hallway, you don't want to spend three minutes asking, "Wait, are you the doctor or the guy who fixes the TV?" You see the scrubs, you know the role.
Comfort and Why It’s Not Just "Pajamas"
Let’s be real. A 12-hour shift is brutal. You’re running. You’re lifting patients. You’re crouching down to check a catheter bag.
If you tried to do that in jeans, you’d have a breakdown by hour four. Scrubs provide a range of motion that regular clothes don't. But it’s the pockets that really matter. A good pair of scrubs is basically a wearable filing cabinet.
A nurse usually carries:
- A stethoscope.
- Trauma shears (the heavy-duty scissors).
- Alcohol pads (literally dozens of them).
- A saline flush or two.
- Two or three pens (that will inevitably be stolen).
- A smartphone or hospital "spectralink" phone.
- Medical tape.
Modern scrub brands have leaned into this. You’ll see "cargo" style scrub pants with 10+ pockets. It’s about efficiency. When things go sideways in an ICU, you can’t be running back to the supply closet because you forgot a piece of tape.
The Psychology of the Uniform
There is a weird psychological thing that happens when you put on scrubs. It’s called "enclothed cognition." A study published in the Journal of Experimental Social Psychology found that people actually perform better on tasks requiring attention when they wear a lab coat or professional medical attire.
For the patient, it’s about trust. If a guy in a hoodie walks into your room and says he’s going to put an IV in your arm, you’re calling security. If a guy in clean, crisp scrubs does it, you offer your arm. It creates a boundary. It says, "I am a professional, and I am here to take care of you."

It also helps the workers leave the job at the door. There is a huge mental health component to "taking off the day." When a healthcare worker gets home and strips off those scrubs, they are shedding the stress, the smells, and the trauma of the hospital. It’s a physical reset.
Breaking Down the Common Misconceptions
People think scrubs are sterile. They aren't. Not really.
Unless a surgeon just pulled a fresh pair out of a sterile pack (which is rare, usually they just wear clean ones with a sterile gown over them), scrubs are just... clean. They pick up bacteria from the elevator, the cafeteria, and the patient's bed rails.
This is why you’ll see some hospitals banning staff from wearing scrubs outside the building. In the UK, for example, many NHS trusts have strict policies about "commuting in scrubs." The idea is that you shouldn't bring "bus bacteria" into the surgical suite, and you definitely shouldn't bring "hospital bacteria" onto the subway.
Another misconception? That all scrubs are the same. They really aren't.
- Disposable Scrubs: Used in high-contagion areas or if yours get "soiled" mid-shift. They feel like paper. They’re terrible.
- Performance Scrubs: Moisture-wicking, 4-way stretch. These are the "yoga pants" of the medical world.
- Basic Cotton Scrubs: The boxy, itchy ones the hospital provides in a vending machine.
The Economics of Wearing Scrubs
Who pays for these? It depends.
In many specialized units like the Operating Room (OR) or Labor and Delivery, the hospital provides the scrubs. You show up in street clothes, change into "hospital-laundered" scrubs, and then change back before you leave. This is the gold standard for hygiene.
But for most floor nurses or clinic staff? They buy their own. And they aren't cheap. A top-tier set of scrubs can easily run $80 to $100. When you need five or six sets, that’s a real investment. This is why the "scrub industry" is a multi-billion dollar business. Brands like FIGS have completely changed the market by making scrubs look "cool" and athletic.

Actionable Insights for Healthcare Workers and Students
If you’re entering the field or just looking to upgrade your gear, don't just buy the first pair you see on Amazon.
Prioritize the Fabric Blend
Look for a polyester-rayon-spandex mix. 100% cotton scrubs wrinkle the second you sit down and they don't breathe well. You want something that wicks sweat because hospitals are notoriously hot (unless you're in the OR, which is an ice box).
Check the Pocket Depth
Test your phone in the pocket. If it falls out when you lean over, those scrubs are useless. You spend half your day leaning over beds.
Consider the "Vending Machine" Reality
If you work in a unit that requires hospital-issued scrubs, don't bother buying fancy ones. You won't be allowed to wear them. Save your money for high-quality compression socks instead—those are actually more important for your health than the scrubs themselves.
Laundering Matters
If you wash your scrubs at home, use a disinfectant additive like Lysol Laundry Sanitizer. Standard detergent doesn't always kill the resistant bugs like C. diff or MRSA that you might accidentally bring home. Wash them on the hottest setting the fabric allows and dry them thoroughly.
Scrubs are more than just a dress code. They are a barrier, a toolbelt, and a uniform of trust. Why do healthcare workers wear scrubs? Because in an environment defined by chaos and microscopic threats, they are the most practical piece of equipment a person can put on.
Next Steps for Success
- Audit your current rotation: Toss any scrubs with thinned-out fabric in the inner thighs or underarms; these are bacteria traps.
- Invest in a "Work-Only" Bag: Keep your scrubs separate from your personal items to minimize cross-contamination.
- Transition Ritual: Change out of your scrubs before leaving the hospital if possible, or immediately upon entering your home, to keep the "hospital environment" out of your living space.
