Clothes for working in humid rooms

Short answer: In a humid room, sweat cannot evaporate. The air is already saturated, so everything you wear gets damp, however good the fabric is. Choose something that dries quickly afterwards, and change more often than usual.

Evaporation does not work in humidity

When the air is saturated, sweat cannot leave the fabric. Evaporation normally removes moisture from clothing, and it needs air that can take in more water. In a laundry, a kitchen, an indoor pool or a greenhouse, that air is missing. So even the best fabric turns damp after a while. See bamboo slips.

Why breathable fabric is not enough

A breathable fabric lets moisture pass through, but the moisture has to go somewhere afterwards. In dry air it disappears quickly. In humid air it stays in the fabric and on the skin. That does not mean the fabric is poor, only that the conditions set a limit. Expect your clothes to get damp, and plan for it.

Choose something that dries quickly afterwards

When you leave the room, the fabric should be able to dry fast. A thin layer dries faster than a thick one, and clothes that are not too tight let air reach the skin again. Think less about how the clothes feel inside the room and more about how they feel ten minutes after you leave. See bamboo socks for women.

Change more often than usual

In humid rooms your clothes become saturated faster, so you need to change earlier. A change in the middle of the day makes a big difference, because you start again with a dry layer. Many people wait until they notice it, but by then the clothes are damp through. Plan the change in advance. See bamboo sweatpants for women.

Socks get damp first

Your feet are often in closed shoes or boots, and in humid air the moisture has an even harder time escaping. That is why socks are often the first thing to feel clammy. A spare pair in your bag takes up almost no room and can be changed in two minutes. It is often the change that feels like the biggest difference.

Layers you can remove easily

A humid room is often warm as well, while the corridor or break room is cooler. Several thin layers are easier to adjust than one thick one, and each dries faster on its own. Take off the outer layer when you go in, and hang it somewhere with dry air, so it is ready when you leave.

Stepping out into the cold

The biggest challenge often comes when you leave the room. Damp clothes cool quickly in cold air outside. Change into a dry set before you go home instead of taking the damp clothes out with you. If you keep a dry layer in your locker or bag, the change takes only a few minutes.

Washing and drying after a long day

Clothes that have been damp all day should be washed, even if they look clean. Hang them up straight away if you cannot wash them at once, so they do not sit damp in a bag. Air drying is gentle on the fabric, and a thin layer dries quickly on a rack before your next shift.

Frequently asked questions

Why does breathable fabric not help in humid rooms

Because evaporation needs dry air. When the air is already saturated, moisture cannot leave the fabric, however well it lets it through.

What can you do instead

Choose something that dries quickly once you leave the room, and change more often than you otherwise would. A dry set in your bag makes it easy.

How often should you change

At least once in the middle of the day. In saturated air, clothes get damp faster than anywhere else, and an early change gives you a dry afternoon.
