Why Do We Wear Underwear?

It’s one of those things we put on every day without thinking twice. Underwear is so woven into our routine that most of us never stop to ask: why do we wear it at all? Is it purely about hygiene, comfort, or fashion—or simply a societal norm that we’ve carried for centuries?

This article explores the real reasons behind underwear: its benefits for hygiene and comfort, its history, fabric types, the cultural forces that shaped it, and even why some people are skipping it entirely.

Key Takeaways

• Underwear provides hygiene, comfort, and support during daily life.
• It helps prevent friction, sweat, and genital irritation.
• Societal norms and cultural history explain why most people wear it.
• Breathable, moisture-wicking fabrics like TENCEL™ make underwear better for workouts and all-day wear.
• Going commando is safe in some cases. What matters most is personal comfort fabric and choice.

So, Why Do We Wear Underwear?

At its core, underwear is practical. It acts as a barrier between your body and your clothes, absorbing sweat and natural discharge while protecting outerwear. It also provides comfort and support during daily movement, keeping everything in place whether you’re sitting at a desk or in the middle of a workout.

Beyond hygiene and support, underwear helps reduce genital irritation by minimizing friction. And when made from breathable, moisture-wicking fabrics, it keeps you cooler and drier, especially during (un)comfortable workouts or long days on your feet.

In other words, underwear quietly performs multiple jobs that most of us take for granted.

Hygiene, Comfort, and Support

When it comes down to it, the three most practical reasons people wear underwear are hygiene, comfort and support. It’s less about fashion or tradition and more about protecting your body (and your clothing) while keeping you supported throughout the day.

1. Hygiene – It prevents sweat, discharge, and bacteria from reaching your outer clothing, reducing odor and extending clothing life.
2. Comfort & Support – It adds a soft, protective layer that keeps you comfortable whether you’re running errands, working out, or sleeping.
3. Moisture Management – Breathable underwear made with moisture-wicking fabrics like TENCEL™ helps regulate temperature and prevents dampness.

Societal Norms & Cultural Influences

While hygiene is important, there’s no denying that societal norms play a huge role in why people wear underwear.

Historically, underwear has been linked to modesty, morality, and even fashion trends. Advertising, movies, and celebrity culture have all shaped what styles we buy and how we think we’re “supposed” to wear them. Gender expectations also influence design—think bras and panties for women, boxers and briefs for men.

In short, while underwear began as a functional garment, societal pressure and cultural influence made it a near-universal habit.

A Brief History of Underwear

• Ancient times: Civilizations used loincloths or simple wraps, mainly for warmth and modesty.
• Middle Age: Europeans wore layered garments to protect clothing and maintain hygiene.
• 1800s: Corsets, bloomers, and men’s drawers became widespread, mixing function with fashion.
• 1900s: Briefs, panties, and bras emerged, driven by utility but also heavily marketed through advertising.
• Today: Comfort, inclusivity, and sustainable fabrics like CUFT®’s 100% TENCEL™ underwear define the market.

Do You Need to Wear Underwear?

Believe it or not, some people choose not to wear underwear at all. Here’s why:

• Benefits of going commando: better airflow, fewer yeast infections for some women, and a feeling of freedom.
• When it’s not ideal to go commando: during workouts (sweat + friction), or when wearing rough fabrics like denim.
• A balanced perspective: going without is fine if it’s comfortable for you, but underwear can provide much-needed support and protection.

At the end of the day, it’s about personal preference and comfort, not societal rules.

The Importance of Fabric

Not all underwear is created equal. The fabric you choose can make or break your comfort:

• Natural fabrics like cotton, TENCEL™, and bamboo are breathable and reduce irritation.
• Synthetic fabrics like polyester and nylon often trap heat and moisture, which can increase the risk of discomfort and genital irritation.

That’s why CUFT® underwear is made from 100% TENCEL™, a plant-based material derived from eucalyptus. It’s naturally moisture-wicking, breathable, and compostable—keeping you comfortable all day without relying on synthetic blends. Perfect for comfortable workouts and daily wear.
